. . The Mysterious Origins of Bitcoin
Introduction
Though the following chapters are mostly devoted to
informing and enlightening the reader about the
potential of cryptocurrency and the underlying
blockchain technology, the origins of these
developments are somewhat shrouded in mystery.
Halloween 2008 may have been a particularly frightening
one, as the world economy was facing its most
dangerous crisis since the Great Depression. Yet, it also
happened to be the day that Bitcoin, the most widely
used cryptocurrency to date, was introduced in a rather
simple and unassuming email to several hundred
members of an obscure mailing list comprising
cryptography experts and enthusiasts.
The sender, known only as Satoshi Nakamoto, wrote:
“I've been working on a new electronic cash system that's
fully peer-to-peer, with no trusted third party,” followed
by directions to the link
http://www.bitcoin.org/bitcoin.pdf, a nine-page white
paper about a peer-to-peer trustless system of digital
“currency” that purports to solve the problem of doublespending.
After first becoming operational in January 2009, Bitcoin
and its related progeny have exploded in just a short
number of years. Exactly seven years after the initial
enigmatic email was sent, the October 31, 2015, cover of
The Economist featured an article on the blockchain (the
technology underlying Bitcoin), dubbing it “the trust
machine.” Blockchain technology, which is described
below, provides a cryptographically secured ledger that
can be examined by all authorized parties, but cannot be
changed.
Though Nakamoto initially collaborated with developers
on what has been called a revolutionizing innovation, his
participation ended in mid-2010, and in April 2011, he
completely disappeared with the final words, “I’ve moved
onto other things.”
Though we may never uncover the originator of Bitcoin,
we are left with a rapidly developing open source
technology that continues to find increasing mainstream
acceptance and simply cannot be ignored.
In fact, we have seen every sign that blockchain
technology will be widely adopted in various industries.
For example, the Hyperledger Project provides open
source blockchain software that can be adapted to
various applications. Intel has joined IBM, Digital Asset
Holdings, and others in providing code and support for
this project.
Also, Digital Asset Holdings has collaborated
with the Depository Trust and Clearing Corporation
(DTCC) to test and build a blockchain-type distributed
ledger to track and settle financial assets. The R3
consortium is a group of FinTech companies and large
banks that are developing a distributed ledger
customized for financial institutions.
The blockchain has also garnered the attention of
government agencies and regulators, of course. For
example, the U.S.
Office of Comptroller of Currency (OCC)
has released a white paper posing an approach to
handling how banking institutions should experiment
with new technologies such as the blockchain. As
discussed below, regulators in other countries and the
European Union are also paying attention.
The application of the blockchain is anticipated to extend
far beyond financial services to include various
applications of authentication and data storage. Potential
applications of the blockchain include real property
records, digital content ownership verification, and
business process management.

Bitcoin 101 – A Primer
Cryptocurrencies1 have gained significant attention since
the introduction of Bitcoin in 2009. They offer a new
medium of exchange created by and for the Internet that
could potentially democratize the very idea of money
itself. The following is a short primer on bitcoin’s
underlying technology2 and a breakdown of a sample
bitcoin transaction. Armed with this understanding, we
can more clearly see the potential impact, issues, and
opportunities presented by Bitcoin, similar
cryptocurrencies, and the underlying blockchain
technology.
Bitcoin became the first decentralized cryptocurrency,
from which hundreds more cryptocurrencies have been
derived.
Essential to its operation are two underlying
technologies: public key cryptography and peer-to-peer
networking.
•
Public key cryptography is the use of digital
signatures to secure information. These signatures
consist of a public key, which is known by everyone,
and a private key, known only by its owner.
•
Peer-to-peer networking is a way to organize the
flow of information among equal participants on a
network, rather than relying on a central authority.
Bitcoin secures transactions between currency users
with digital signatures and then requires verification over
a peer-to-peer network. Thus, when spending bitcoins3,
you sign the transaction with your private key to prove
you own the bitcoin you want to spend.
Then, your public
key and the details of the transaction are published to a
public ledger so that everyone knows that your bitcoin
has changed hands. This public ledger is constantly being
verified by the members of Bitcoin’s peer-to-peer
network to ensure that each bitcoin is spent only once
and is held by its verifiable owner. As such, Bitcoin
replaces trust with mathematical proof and
accountability among currency users themselves,
thereby doing away with a central authority to monitor
the currency, or trusted third parties to clear
transactions.
Unlike a digital file on your computer, a bitcoin cannot be
copied and pasted infinitely.
It can only be transferred,
and transferred only once, by signing the transaction
with your private digital key and recording the
transaction on a shared public ledger.
Not only did Bitcoin solve the so-called “double spending”
problem, where currency risked being spent more than
once without the involvement of a middleman, but just
as importantly, Bitcoin, owing to this middleman
02 Reed Smith LLP Bitcoin 101 – A Primer
elimination, cut down the time required to verify and
finalize transactions from what can take several days in a
traditional system, to a matter of minutes – thereby
enabling significant efficiencies and the growth of
tremendous opportunities.
The Blockchain
Bitcoin relies on its peer-to-peer network to do two
things: maintain the authoritative ledger of transactions
and issue new currency. To understand how this works,
we must briefly explain the bookkeeping algorithm
behind Bitcoin, known as the blockchain4. The
blockchain is a decentralized ledger that records
information about transactions occurring in real time in
“blocks” that are linked together through a secure
mathematical function, thereby forming a chain of
records (hence the name blockchain).
To add a new block of records to the blockchain,
someone must discover the mathematical key (called a
“nonce”) that will fit the next block of records into the
chain.
This is done by making millions upon millions of
guesses (done by computers), the process of which is
called “mining” and is done by participants on the Bitcoin
network. Once discovered, the nonce must also be
double-checked by other users in order to be verified.
Mining secures the ledger, because once a block of
records is added to the blockchain, the transactions
recorded are considered final. In order to tamper with
those records, a fraudster would have to re-discover the
proof that allowed the records to be added in the first
place.
This is very unlikely for two key reasons. First, the
Bitcoin network is built to adjust the difficulty (up or
down) of finding the key, based on the amount of
computing power on the network, to ensure that just the
right amount of work is necessitated for mining so that it
is neither too hard (thereby requiring too much time),
nor too easy. Second, the Bitcoin network is designed to
follow only the longest chain of blocks.
This means that
in order to go back and tamper with the ledger, you
would have to find the key for the block you want to
change and any others that were found after it in order
to replace the longest chain. The computational difficulty
of that task is so high that most bitcoin transactions are
considered verified after six blocks are added to the
network (which takes one hour on average).
So why do miners dedicate computing power to finding
mathematical keys to verify bitcoin transactions? The
answer lies in how new bitcoins are issued. Rather than
relying on a central bank or other authority, the Bitcoin
network itself creates new bitcoins as a reward for
.
miners who successfully find the next key. The miner
who successfully creates a block of records receives a set
reward of new bitcoins, plus any transaction fees
attached to the transactions that the block records. This
incentive has led to the creation of large bitcoin mining
pools and other organizations dedicating raw computing
power to claim new bitcoins, while at the same time
securing Bitcoin’s ledger.
A Bitcoin Transaction
It would be illustrative to follow one bitcoin transaction
from beginning to end to see how all the pieces fit
together5. Say Alice, who owns three bitcoins, wants to
send Bill two bitcoins.
She would go to her digital “wallet,”
which is a program or online service that stores the keys
that Alice needs to access her bitcoins. Alice puts in the
address for Bill’s digital wallet, which is a 27-34 character
code. She knows that the Bitcoin network tends to
prioritize recording transactions that include a fee, so
she offers 0.05 bitcoins to the miner who records her
transaction.
Alice’s digital wallet creates a data packet containing Bill’s
wallet address, the number of bitcoins to be sent, the
0.05 transaction fee, and Alice’s digital signature.
This
data packet is propagated through the Bitcoin network. It
will flow in Bitcoin’s peer-to-peer network, from one
computer to another, until each member knows of the
pending transaction (this will usually take less than a
minute).
Within about 10 minutes, a miner finds the right nonce
to record the next block of transactions. This miner
prefers transactions with fees attached, so Alice and Bill’s
transaction is at the top of the queue to record.
The new
block of records contains the solution to the block, a
reference to the prior block in the blockchain, and a list
of all transactions, now time-stamped, that the block
records, including Alice and Bill’s.
Note that the transaction now has one input and three
outputs. The input is Alice’s original wallet address of
three bitcoins. The three outputs are: (1) the two bitcoins
going to Bill, (2) the 0.05 bitcoins going to the solver of
this block, and (3) a new public key for 0.95 bitcoins
going back to Alice as the change for the transaction.
This new address is added to Alice’s digital wallet, and is
associated with her private key indicating Alice’s
ownership.
Now that the transaction is recorded in a block, it will
soon be considered final.
The new block of records is
broadcast to the Bitcoin network. The transaction
becomes final as more and more blocks are found with
this transaction included. This will inevitably occur
because the probability that there is a competing chain
with more work performed on it falls to zero.
As long as
it appends to the longest confirmed blockchain, it is now
considered a part of Bitcoin’s ongoing ledger.
In order for Alice and Bill to be satisfied that the
transaction is confirmed, they will typically wait for five
more confirmations to reduce the probability that a
fraudulent miner recorded or changed a block. This
confirmation will normally happen within an hour. Once
it does, Alice and Bill’s digital wallet programs will alert
them that the transaction is confirmed, and they can be
confident that they can spend their new bitcoins.
Summary
Bitcoin and other decentralized cryptocurrencies
eliminate the middleman that verifies transactions and
controls currency.
Thanks to ongoing development by a
dedicated online community, this technology has
spawned new types of businesses, new channels of
commerce, and a renewed discussion over how the
Internet impacts economies across the globe. However,
bitcoin as a currency is merely the tip of the iceberg of
what the blockchain has to offer.

.
As time goes on, more and more blocks of records are
added to the blockchain, each one securely referencing
the next. This is important because if someone wanted
to go back and change a transaction on the ledger – to
cook the digital books – she would not only have to resolve the mathematical puzzle allowing her to create a
fraudulent block, but she would also have to re-solve
every subsequent block in the blockchain. Even worse for
the fraudster, she would have to convince a majority of
network participants to accept these fake blocks before
the next legitimate participant added the next real block.
The sheer volume of work and speed required make it
extremely difficult to alter transactions on a blockchain.
This means that after a certain number of new blocks are
added, the parties to a transaction can be well-assured
that the transaction is considered final – not only by
them, but also by the entire community of participants
on the network. It is precisely this assurance that allows
blockchain participants to trust the ledger itself, even
though they do not necessarily trust (or know) their
fellow participants on the network.
Advantages of Blockchain
Distributed ledgers like Blockchain solve important
problems in Internet commerce.
Chief among them is
the problem of double spending, where two transactions
draw upon the same underlying asset. By requiring every
transaction to be at least partly public, distributed
ledgers dramatically increase counterparty trust.
Moreover, because Blockchain requires proof of work
and consensus to record new transactions, it is very
difficult for fraudsters to tamper with digital records to
steal or re-spend assets.
Blockchain also helps achieve certainty in the concept of
digital ownership itself. A consummate problem with
digital information is that it is freely transferable and may
be copied.
This means that possession cannot be
equated with ownership. Merely having a copy of a file
does not include the right to exclude – a touchstone
right built into the concept of property. Distributed
ledgers like blockchain make proving the ownership of a
digital asset more like performing a real property title
search.
Like the grantor-grantee index in land records,
the blockchain records every transaction involving a
particular digital asset. The advantage of blockchain over
other forms of exclusive digital ownership, like
encryption at rest,8 is that there is always a record that
reflects not only the current possession of the asset, but
also the history of rightful ownership going all the way
back to the digital asset’s creation.
Disadvantages of Blockchain
Like all technical solutions, the blockchain algorithm
reflects certain tradeoffs. Because of latency and
scalability issues, many current blockchain applications
put severe limits on the size of each new block of
records.
This limits the frequency with which a
blockchain network can process transactions. For
example, the Bitcoin network can only process seven
payments per second, while major credit card providers
can handle more than 1,400. Designers of applications
that leverage blockchain should carefully consider
factors such as block size, the proof of work required to
verify blocks, and the expected number of participants
on a blockchain, to ensure the ledger operates efficiently
and effectively.
Blockchain relies heavily on public key cryptography to
identify users and permit access to assets tracked
through the ledger.
For this reason, key security is of
increased concern. If a user’s private key is lost or stolen,
the user has lost access to his or her assets on the
blockchain forever. For example, as many as 4 percent of
bitcoins have been rendered permanently ownerless
because users have misplaced their digital keys.
Future
applications of blockchain, especially in private or semiprivate contexts, should consider employing multi-factor
authentication or digital certificates to safeguard the
cryptographic keys used to identify rightful owners and
permit access.
While smaller blockchain networks may offer more
technical security options, they are not necessarily safer.
Organizations that host private or semi-private
blockchains should especially consider the possibility of
so-called “51% attacks,” where the majority of the
network’s mining hashrate is concentrated in a single
entity, thereby allowing that single entity to manipulate
the public ledger at will. In addition, the pseudonymous
nature of blockchain transactions can make fraud
detection and collusion between users more difficult to
detect. Carefully consider the sensitivity of information
stored in a distributed ledger, the type and number of
network participants, and the incentives for fair play on
the network.

Summary
The blockchain algorithm is an important contribution to
the foundational technologies we use to store and
secure information. It addresses particular problems
with counterparty trust and digital asset ownership.
While not a panacea, the blockchain algorithm presents
exciting opportunities in how we store and share
information securely online. Many commentators posit
that the invention of the blockchain will be remembered
in the same vein as the invention of the World Wide Web
06 Reed Smith LLP Bitcoin 101
or email.9 As a foundational technology, the blockchain
could one day be a major part of how we store and
transmit electronic information itself.10 The opportunity
is wide open for innovators to apply blockchain across
the digital landscape. Armed with an understanding of
how the blockchain works, you can be a part of that
conversation.

U.S. Regulatory Landscape
In the United States, it is currently legal to transmit, mine,
and develop cryptocurrencies, such as Bitcoin. It is also
generally legal to use cryptocurrencies to purchase
goods and services, or for investment purposes.
However, with their dramatic increase in prevalence and
overall use, cryptocurrencies have become the target of
regulations issued by both the federal and state
governments. The increase in regulatory oversight has
been particularly significant during the past year.
One state, New York, has already issued regulations
explicitly subjecting those engaging in virtual currencybased business activities to licensing, supervision, and
other compliance requirements.
In addition, various
federal agencies have provided guidance that certain
virtual currency-related activities may be subject to
already-existing regulations, such as those governing
money transmission.
Furthermore, several agencies have initiated
enforcement actions against businesses and individuals
related to cryptocurrency activities. The focus of these
regulations tends to be on virtual currencies themselves
and their transmission, as opposed to the pure
development of cryptocurrency technology and software.
For example, the New York BitLicense regulations
explicitly provide that those who only develop virtual
currency software and technology are not subject to
licensure.
These recently promulgated regulatory regimes, along
with the guidance provided by other agencies clarifying
the application of already existing regulations to virtual
currency-related activities, have major implications to
companies engaged in virtual currency activities from a
licensing, supervision, compliance, and cost perspective.
Undoubtedly, with the sustained growth of
cryptocurrency, governments will continue to adapt, and
one can expect additional regulations from
governmental authorities within the coming years.
State Regulation
New York: The BitLicense Regime
Led by former Superintendent of Financial Services Ben
Lawsky, New York state has been at the forefront of
virtual currency regulation since 2014. In July 2014,
through its Department of Financial Services (“NYDFS”),
New York became the first state to propose a
comprehensive regulatory regime governing virtual
currency business activities.11 And on June 3, 2015,
following comments from numerous interested parties,
New York became the first state to implement a
comprehensive virtual currency regulatory regime –
popularly known as “BitLicense.”12
As of September 2015, NYDFS has already received 25
initial BitLicense applications.13 Recently, NYDFS issued
the first license under the BitLicense regime to Circle
Internet Financial, a Bitcoin wallet and creator of the app
Circle Pay.14 However, the BitLicense regulations have
been divisive, and some have criticized the burdens that
it places on virtual currency-related businesses.
As a
result, some companies have attempted to block users
from New York in an attempt to avoid falling under the
BitLicense regulations.15
Under the BitLicense regime, companies engaged in
“virtual currency business activities” Under the BitLicense
regime, companies engaged in “virtual currency business
activities” are required to undergo a thorough
application process, obtain a license, abide by numerous
compliance requirements similar to banks and other
financial institutions, and be subject to examinations by
NYDFS.
Who Must Obtain a License?
Under BitLicense, a “virtual currency” is a digital unit that
is a digital medium of exchange or form of stored value,
with specific exceptions for prepaid cards, customer
rewards programs, in-game currency and reward
points.16
Companies that conduct “virtual currency business
activities,” as defined in the BitLicense regulations, and
that operate in New York, or engage in business with
New York customers, are subject to the BitLicense
regime.17
Under BitLicense, the following five activities constitute
“virtual currency business activities”:
•
Receiving virtual currency for transmission or
transmitting virtual currency through a third party
•
Maintaining custody of virtual currency or holding
virtual currency on behalf of others
•
Buying or selling virtual currency as a customer
business
•
Performing virtual currency exchange or conversion
services (whether converting virtual currency to fiat
currency or vice versa; or converting one type of
virtual currency for another type of virtual currency)
U.S. Regulatory Landscape Reed Smith LLP 07
. •
Controlling, administering, or issuing virtual
currency18
BitLicense exempts several activities from licensure. For
example, cryptocurrency mining on its own would not
subject a party to the BitLicense regime.19 Similarly,
consumers or merchants only using virtual currency to
buy or sell goods or services would not be required to
obtain a license.20 And finally, parties who engage purely
in software development and dissemination do not fall
under BitLicense.21 However, there are many
unanswered questions as to the particular
circumstances in which various exceptions would apply.
For example, BitLicense exempts from licensure the
transmission of “nominal amounts” of virtual currency for
“non-financial purposes.”22 Some have surmised that
this would allow for transmission of nominal amounts of
cryptocurrency for purposes of, for example, identity
verification. However, it is less clear whether this
exception would apply to the use of a nominal amount of
cryptocurrency to create a “digital contract.” Likewise,
there are several gray areas as to whether certain
businesses are engaged in one of the five “virtual
currency business activities,” or mere software
development.
Application and Licensing Process
The BitLicense application and licensing process is
extensive, and is similar to the licensing required for
other types of financial institutions chartered in New
York. Applicants must pay a $5,000 application fee, and
submit to NYDFS extensive biographical, historical,
financial, and business information about the applicant,
its principal officers, and its principal stockholders.23
Under BitLicense, NYDFS must approve or deny
applications within 90 days of deeming the application
complete.24 However, in practice, the regulators can also
ask for more documentation, and likely often will as is
the case with other financial regulatory licensing.
Further,
the superintendent may also extend the 90-day window
in certain cases.25 Therefore, as with the licensing
process for other financial institutions, the BitLicense
application will likely be time- and cost-intensive.
NYDFS may also issue conditional licenses under
BitLicense for those applicants that do not comply with
all BitLicense requirements upon licensing.26 This
conditional license is valid for two years. However, the
conditional license may be issued subject to reasonable
conditions imposed by NYDFS, and the licensee may be
subject to heightened scrutiny, review, and examination.
Licensees must also obtain NYDFS written approval to
offer any materially new product, service, or activity, or to
make a material change to an existing product, service,
or activity.27 Finally, NYDFS has the authority to suspend
or revoke both full and conditional licenses on several
08 Reed Smith LLP U.S. Regulatory Landscape
grounds, including on any ground that the
superintendent may refuse an initial license, for violation
of any provision of BitLicense, good cause, or for failure
to pay a judgment.28
AML, KYC, Compliance Issues, and Examinations
Perhaps the most significant BitLicense provisions are
the numerous ongoing compliance provisions that the
NYDFS requires of licensees.
Many such compliance
regulations are similar to those required of New Yorkchartered banks and other types of financial institutions.
Licensees under BitLicense must maintain a
comprehensive anti-money laundering (AML) policy.29
This policy is subject to both an initial risk assessment
and ongoing annual risk assessments.30 Licensees must
adopt internal controls and policies to ensure AML
compliance, including appointing a dedicated compliance
officer and subjecting the policy to review and approval
by the licensee’s board of directors.31 The policy must be
subject to annual independent testing, and the audit
report must be submitted to NYDFS.32
The AML provisions also include numerous additional
know-your-customer (“KYC”) requirements similar to
those in existence for other financial institutions, or for
money transmitters under FinCEN regulations.33
Licensees must identify and verify customers’ identities,
check customers against the list of Specifically
Designated Nationals maintained by the Office of Foreign
Assets Control (“OFAC”), and maintain customer
records.34 Licensees are also required to submit to
NYDFS suspicious activity reports (“SARs”) and currency
transaction reports for transactions in cryptocurrency of
more than $10,000.35
Additional compliance regulations promulgated by the
BitLicense regime include those addressing a licensee’s:
•
Capital requirements36
•

Conference of State Bank Supervisors
On September 15, 2015, the Conference of State Bank
Supervisors issued a model licensing regime as a guide
to states in regulating virtual currency. The Conference
recommends that companies involved in the exchange
and transmission of virtual currencies and “services that
facilitate the third-party exchange, storage and/or
transmission of virtual currency (e.g. wallets, vaults,
kiosks, merchant-acquirers, and payment processors),”
be supervised and licensed by state banking regulators.47
“Virtual currency” is defined here as a digital
representation of value used as a medium of exchange,
unit of account, or store of value, but which does not
hold legal tender status. Virtual currency would not
include the software or protocols governing transfer.48
Other State Proposals
Following New York’s lead, other states have made
various proposals to implement virtual currency
regulations within the past year.
Perhaps most prominently, in June 2015, the California
House of Representatives passed AB-1326.49 The bill,
introduced in February 2015, would provide for a similar,
but not quite as extensive, licensing regime to New York’s
BitLicense.50 Like BitLicense, AB-1326 would provide that
virtual currency businesses could not operate unless
licensed by the California Department of Business
Oversight.
The proposal also calls for capital
requirements and an extensive application process.
However, the California proposal would be more relaxed
than BitLicense in certain areas: for example, it would
not require submission of state-level SARs and would
contain less stringent AML requirements. As of
September 2015, AB-1326 stalled in the California
Senate and is no longer listed as an active bill; however, it
could be revived on a future date.51
At least three states have issued guidance as to how
state law, particularly concerning money transmission,
applies to virtual currency transactions. Washington
state has concluded that virtual currency is included in
the definition of “money transmission” in its Uniform
Money Services Act.52 However, both Kansas and Texas
have concluded that virtual currency does not constitute
money under its money transmission laws, and therefore,
the two states’ respective money transmission laws
generally do not apply to virtual currency transactions;
the one exception may be where the acts may apply is
transactions in which virtual currency is exchanged for
sovereign fiat currency through a third-party exchange
site.53
New Jersey, Connecticut, Pennsylvania, North Carolina,
Utah, and New Hampshire have also made various virtual
currency regulation proposals; however, none has been
adopted as of this writing.54
Federal Regulation
Unlike New York state, federal agencies have not yet
issued specific sets of regulations specifically addressing
virtual currency.
However, in recent years, agencies have
clarified that certain laws and regulations already in
existence may apply equally to activities and transactions
involving virtual currency as to those involving traditional
fiat currency. Two of the agencies whose regulations
may most impact virtual currency businesses include the
Commodity Futures Trading Commission (“CFTC”) and
Financial Crimes Enforcement Network (“FinCEN”).
Commodity Futures Trading Commission (“CFTC”)
On September 17, 2015, the CFTC confirmed that it
would treat bitcoin and other virtual currencies as
“commodities” for regulatory purposes under the
Commodity Exchange Act (“CEA”) and other CFTC
regulations.55 Under the CEA and its regulations, the
CFTC may assert jurisdiction over the trading of futures,
options, and swaps on “commodities.”56 The term
“commodity” is defined broadly to include “goods and
articles…and all services, rights and interests…”57 The
CFTC’s determination came in the form of a settlement
order against Coinflip, Inc., which is discussed in more
detail below. The decision to treat virtual currencies as
“commodities” under the CEA and CFTC regulations
confirms prior informal guidance provided by CFTC
Chairman Timothy Massad and other CFTC officials, who
had commented in testimony and speeches that the
CFTC would be able to assert jurisdiction over virtual
currencies.58 The order also appears to confirm that the
CFTC would only treat virtual currency as a “commodity,”
and that it would not treat virtual currency as “currency”;
and therefore virtual currencies would not be subject to
certain regulations governing foreign exchange
derivatives.59
The treatment of virtual currency as a “commodity”
carries significant implications for businesses that
engage in the trading of virtual currency-based
derivatives.
Such firms that come under the CFTC’s
jurisdiction may have to register with the CFTC, and could
be subject to regulation by the CFTC and/or the National
Futures Association. This supervision will undoubtedly
subject the firms to numerous regulatory obligations. As
a result of the CFTC’s September 2015 settlement with
Coinflip, almost any business whose business activities
involve virtual currency-based derivatives will need to
assess whether it is required to register with the CFTC
and may be subject to CFTC regulation.
Two such
businesses might include firms running trading platforms
U.S. Regulatory Landscape Reed Smith LLP 09
. involving virtual currency-based derivatives, or firms
providing advisory services concerning virtual currencybased derivatives.
Financial Crimes Enforcement Network (“FinCEN”)
Like the CFTC, FinCEN has not issued any regulations
directly addressing virtual currency. However,
businesses engaged in virtual currency activities may
come under the purview of FinCEN’s regulations
concerning money services businesses (“MSBs”). Under
FinCEN regulations, MSBs include “money transmitters.”60
In 2011, FinCEN opened the door to regulation of virtual
currency businesses as money transmitters – and
therefore MSBs – when it revised the definition of
“money transmission services” to include “the acceptance
of currency, funds, or other value that substitutes for
currency from one person and the transmission of
currency, funds, or other value that substitutes for
currency to another location or person by any means.”61
Therefore, any party that engages in the transmission of
virtual currency must abide by FinCEN’s MSB regulations,
just as if the business transmitted traditional currency.
The implications for being deemed a money transmitter
and MSB are significant. MSBs must comply with
numerous AML requirements, including implementation,
adoption, and maintenance of an AML program;
independent review of such AML program; filing of SARs
and currency transaction reports; and maintenance of
records.62 Further, MSBs must register with FinCEN.
It is
a federal crime to knowingly conduct an MSB while failing
to register with FinCEN (or state licensing money
transmission licensing agencies).63
Starting in 2013, FinCEN has issued guidance clarifying
what types of virtual currency activities could trigger
treatment as an MSB by FinCEN. In March 2013, FinCEN
provided three types of parties that may engage in virtual
currency activities:
•
Users (those who use virtual currency to purchase
goods or services)
•
Exchangers (those providing for the exchange of
virtual currency for real currency, funds or other
virtual currency)
•
Administrators (those issuing virtual currency, or
with the authority to redeem virtual currency)64
FinCEN concluded that, broadly speaking, users of virtual
currency would not be considered MSBs, but that
exchangers and administrators would fall under the
MSB regulations.65
Since then, FinCEN has provided additional guidance as
to what types of activities may trigger regulation. FinCEN
has issued various guidance providing that it would not
10 Reed Smith LLP U.S.
Regulatory Landscape
view the following activities as subjecting a party to MSB
regulations:
•
Mining virtual currency66
•
Use of virtual currency to purchase goods and
services67
•
Conversion of virtual currency to fiat currency for
one’s own use68
•
Investing in virtual currency for one’s own account69
•
Renting out of computer systems and software that
mine virtual currency to third parties (where any
virtual currency mined by the third party using the
software would remain the property of that third
party)70
Many of the above were deemed not to constitute the
activities of an MSB because they were performed for
one’s own account; however, as soon as such activities
were performed by or on behalf of a third party, the
analysis could change.
On the other hand, FinCEN has confirmed that the
following activities would constitute engaging in business
as an MSB:
•
Maintaining a trading system to match offers to buy
and sell virtual currency for fiat currency71
•
Maintaining a set of book accounts where customers
may deposit virtual currency72
•
Developing and maintaining a system to provide
virtual currency payments to merchants in the United
States and Latin America wishing to receive payment
for goods/services sold in a currency other than that
of legal tender73
•
Conducting Internet-based brokerage services
between buyers and sellers of precious metals, in
which buyers pay sellers directly by check, wire, or
bitcoin; and the entity uses the bitcoin blockchain to
transfer previous metal ownership by issuing a digital
certificate. The customer could then later exchange
its holdings using the bitcoin blockchain ledger.74
Other Federal Agencies
Numerous other federal agencies have also issued
guidance on virtual currency or issued consumer
advisories, although not as significant as the CFTC’s or
FinCEN’s interpretations. For example, the Securities and
Exchange Commission (“SEC”) has issued guidance
stating that, even if it does not consider virtual currencies
to be “securities,” it may still invoke its enforcement
authority to prosecute virtual currency-based Ponzi
schemes and other fraud – which it has already done.75
.
The Internal Revenue Service has concluded that
cryptocurrency should be considered “property” under
the Internal Revenue Code, and thus transfers involving
virtual currencies would be taxable events.76
Other agencies issuing guidance and consumer
advisories include the Consumer Financial Protection
Bureau, Board of Directors of the Federal Reserve
System, the Federal Deposit Insurance Corporation, the
Office of the Comptroller of the Currency, the Federal
Trade Commission, and FINRA.
Enforcement
Over the past several years, various federal agencies
have stepped up their enforcement of virtual currencyrelated activities. Although no federal agencies have yet
issued virtual currency-specific regulatory regimes, such
as New York’s BitLicense, the agencies have prosecuted
numerous individuals applying existing laws to virtual
currency-based activities. In some cases, these
enforcement actions have been precedent-creating, such
as the settlement agreement between Coinflip and the
CFTC, in which the CFTC confirmed its interpretation that
virtual currencies constituted “commodities” under the
CEA.
Some examples of key enforcement actions include the
following:
CFTC
On September 17, 2015, the CFTC settled an
enforcement action against Coinflip, Inc. and its chief
executive officer.
Coinflip operated an online facility
called Derivabit that matched buyers and sellers of
bitcoin option contracts. The CFTC found that Coinflip
was operating a facility for trading commodity options in
violation of the CEA and CFTC regulations, including by
operating the facility without having registered with the
CFTC. Although the Order did not carry any monetary
penalties, this enforcement action was especially
significant because, through the Order, the CFTC
established that it considered virtual currencies to be
“commodities” under the CEA, and thus could exercise
jurisdiction over various virtual currency-related
derivatives.77
FinCEN
On May 15, 2015, FinCEN issued a $700,000 civil
monetary penalty against Ripple Labs, Inc.
for willful
violations of the Bank Secrecy Act regulations.
Specifically, FinCEN accused Ripple of acting as a money
services business by selling virtual currency. However,
Ripple did not register with FinCEN, failed to implement
appropriate AML programs, and failed to report
suspicious activities, among other violations.78
SEC
In September 2014, the United States District Court for
the Eastern District of Texas entered a final judgment
against Bitcoin Savings & Trust and Trenton Shavers
following an SEC enforcement action. The SEC alleged,
and the court found, that Bitcoin Savings & Trust and
Shavers conducted a Ponzi scheme soliciting
investments in bitcoin-related investment
opportunities.79
In December 2014, the SEC sanctioned Ethan Burnside
for operating two digital currency exchanges without
registering them as either broker-dealers or stock
exchanges.80
In June 2014, Erik Vorhees was sanctioned by the SEC for
violating sections 5(a) and 5(c) of the Securities Act of
1933 for publicly offering unregistered securities in two
Bitcoin-related ventures, SatoshiDICE and FeedzeBirds.81
FBI/DOJ
Following an investigation by numerous agencies, Ross
Ulbricht was sentenced to life in prison in May 2015 in
connection with his role in Silk Road.
Mr. Ulbricht
founded Silk Road, an online black marketplace used to
facilitate criminal activity; the site was later shut down by
government task forces. Mr.
Ulbricht was found guilty in
February 2015 of conspiracy to distribute controlled
substances, computer hacking, and money laundering.82
Blake Benthall, who operated Silk Road 2.0, a follow-on
site to Silk Road, was arrested in November 2014 on
similar charges.83
Charlie Shrem, a former vice chairman of the Bitcoin
Foundation, and Robert Faiella, were arrested for
unlawfully converting dollars into bitcoin for users of Silk
Road. Each pleaded guilty in September 2014, and were
sentenced to two years and four years in prison,
respectively. Shrem and Faiella were charged with
operating an unlicensed Money Transmitting Business
(failure to register with FinCEN), money laundering, and
willful failure to file SARs with FinCEN.84
Conclusion
The explosion of cryptocurrencies over the past several
years has not escaped the attention of regulators in the
United States.
For at least the past two years, agencies
have applied already existing laws and regulations to
adapt to the virtual currency landscape, notably FinCEN
and the CFTC. In addition, New York’s BitLicense regime
became the first comprehensive regulatory regime
aimed squarely at regulating virtual currency. The
continued growth and prevalence of cryptocurrency will
undoubtedly continue to solicit attention from regulators
and additional regulations and enforcement actions at
the federal and state level.
U.S.
Regulatory Landscape Reed Smith LLP 11
. International Regulatory Landscape
Internationally, the regulation of cryptocurrency varies
substantially by jurisdiction. Some countries have
minimal regulations on the subject. Several countries
have proceeded with cryptocurrency regulation in ways
similar to the United States—that is, they are currently
studying the potential regulation of virtual currencies,
and are working to adapt and/or update their alreadyexisting anti-money laundering (“AML”) and money
transmission laws and regulations to cover virtual
currencies. These countries include, among others,
Canada, France, Italy, Singapore, and Japan.
Within Europe, the European Court of Justice just ruled
that bitcoin should be treated as a currency.
This ruling
will undoubtedly have a major impact on virtual currency
regulation in the international sphere, and stands in
contrast to the U.S. CFTC’s decision that virtual
currencies should be treated as commodities. This and
future rulings, along with a 2014 Opinion issued by the
European Banking Authority urging an EU-wide virtual
currency regulatory regime, could have the effect of
unifying European regulation on the subject, which had
varied more substantially from country to country.
However, other countries have imposed much more
stringent regulations, and in some cases have banned or
criminalized the use of virtual currencies.
These more
stringent laws may make it effectively impossible to deal
in virtual currency in various countries. For example,
Russia has recently proposed legislation to make the use
of virtual currency a criminal misdemeanor. Virtual
currency has been banned outright in Ecuador and
Bolivia (although the Ecuadorian government has
created its own state-backed digital currency).
In
Bangladesh, virtual currency is not considered legal
tender, and its use may lead to jail time. Iceland has
indicated that virtual currency is not protected currency,
and its purchase may violate the country’s Foreign
Exchange Act. And the Chinese government has
instructed its commercial banks to halt all dealings with
virtual currency exchanges, and has prohibited these
banks from clearing virtual currency transactions –
particularly notable since more than 80 percent of
bitcoin transactions take place in Chinese yuan.
As noted above, international regulation of virtual
currency is fast-evolving and varies substantially across
jurisdictions.
This chapter is just a sampling of notable
regulations in certain countries, and is not meant to
serve as a thorough analysis of all virtual currency
regulations across the globe.
12 Reed Smith LLP International Regulatory Landscape
Europe
October 2015 European Court of Justice Ruling
In one of the first major virtual currency court cases
impacting the European Union as a whole, on October
22, 2015, the European Court of Justice (“ECJ”) held that
bitcoin should be treated as a currency and means of
payment for tax purposes.85 This holding stands in
contrast to regulation in the United States, in which the
U.S. Commodity Futures Trading Commission (“CFTC”)
has recently determined that virtual currencies should
not be treated as currencies, but instead as
commodities.86
The ECJ’s ruling has major implications for all players in
the cryptocurrency space, especially from a tax
standpoint. Under the EU’s Directive concerning value
added taxes (“VAT”), member states may not use their
value added taxes to tax “transactions, including
negotiation, concerning currency, bank notes and coins
used as legal tender.”87 Because the ECJ held that virtual
currencies constitute currency and a means of payment
for purposes of the EU’s VAT Directive, the EU member
states may not use their VAT to tax cryptocurrency
transactions.
Therefore, bitcoin and virtual currency
exchanges that convert traditional currency to virtual
currency are exempt from VAT, and consumers making a
bitcoin exchange would not face a VAT charge as a result
of the transfer. A holding by the ECJ that virtual
currencies should be treated more like commodities (in
line with the CFTC) would have made transfers of fiat
currency to virtual currency potentially taxable under
various EU members’ VATs, similar to the general tax
treatment of other commodities.
The ECJ’s ruling was also significant because it resolved a
conflict among the member states’ taxing authorities on
how exactly to treat virtual currency from a tax
perspective—whether as a currency or a commodity.
For example, while the UK tax authority had taken the
position—like the ECJ—that virtual currency should be
treated as a currency, the tax authorities from Sweden
and Germany argued that virtual currency should be
treated as a commodity, and thus subject to the VAT.88
The ECJ’s ruling should provide a boost to bitcoin and
other cryptocurrency trading in Europe, adding certainty
that exchanges involving cryptocurrencies may be made
free of VAT. The ruling had an immediate impact on
bitcoin, as its price rose 3 percent immediately following
news of the ruling.89 It may also pave the way for
additional harmonizing of virtual currency regulations
across the EU member states.
.
It should be noted that this ruling applies primarily to the
application of the VAT to the exchange of fiat currency
for virtual currency, or vice versa, or the exchange of
virtual currency for another type of virtual currency.
Sales of goods and services subject to VAT but paid for
with virtual currency would likely still be subject to VAT.
And any capital gains on virtual currency appreciation
could still potentially be taxed by member states in
conjunction with their income tax laws.
European Banking Authority Opinion
In July 2014, the European Banking Authority (“EBA”)
issued an opinion regarding virtual currency, providing
recommendations to the EU Council, European
Commission, and European Parliament regarding an EUwide regulatory regime of virtual currencies.90 The
opinion also provides recommendations to national
banking authorities regarding intermediate regulatory
steps that can be taken to address the risks of virtual
currency before a full European regulatory regime is
implemented.
Overall, the EBA’s Opinion concluded that, although
virtual currencies have the potential to create certain
benefits –particularly in the areas of reduced transaction
costs and increased transaction speeds – these benefits
would have less impact in the EU, because of EU
directives aimed squarely at those same goals. 91 The
Opinion also found that the numerous risks of virtual
currency (more than 70 were identified in the Opinion)
would likely outweigh the potential benefits.92
In order to address the numerous risks of virtual
currency, the EBA’s Opinion advocated that “a substantial
body of regulation” be implemented.93 Such a
comprehensive regulatory regime would need to include,
at a minimum, measures addressing governance
requirements of market participants, segregation of
client accounts, capital requirements, and the creation of
“scheme governing authorities.”94 In order to mitigate
the risks of virtual currencies prior to the implementation
of such a regulatory regime, the EBA recommended that
national banking authorities should immediately
“discourage credit institutions, payment institutions and
e-money institutions from buying, holding or selling
virtual currencies.95 Finally, the EBA urged EU legislators
to declare market participants in virtual currencies as
“obligated entities” under the EU’s Anti Money
Laundering Directive, and therefore subject to AML and
counter-terrorist financing requirements.96
Regulatory Status of Cryptocurrencies in Individual
European Countries
Although the ECJ’s recent ruling has provided clarity on
the tax status of virtual currency in EU member states,
the regulations of virtual currency across Europe still vary
substantially. Generally speaking, the mining, exchanging,
and buying and/or selling of goods or services with
cryptocurrency is generally legal and permitted across
Europe. However, much like the United States, many
European countries are currently seeking to apply
existing laws to virtual currency, virtual currency
transactions, and players in the virtual currency space.
For example, Germany, France, Italy, and the Czech
Republic, among others, have explored adapting existing
laws concerning money transmission, AML, taxation, and
registration/licensure of financial institutions to apply to
virtual currency.97 Of course, any prior differences on tax
treatment of virtual currency vis-à-vis the VAT may now
be eliminated following the ECJ ruling.
Notable European nations that many view as having less
stringent virtual currency regulation include the United
Kingdom and Switzerland.
Many believe the United
Kingdom has a relatively more favorable view of
blockchain and digital ledger technology. Numerous
technology incubators focusing on blockchain technology
and cryptocurrencies, such as those backed by Barclays
and others, are headquartered in the United Kingdom.
Further, in September 2014, the Bank of England
released papers praising the potential benefits of
blockchain technology and its potentially wide impact on
the financial system as a whole. The Bank of England’s
papers note that distributed ledger technology is “the
key innovation of digital currencies,” and is “a genuine
technological innovation which demonstrates that digital
records can be held securely without any central
authority.” The Bank of England has also concluded that
virtual currencies as a whole “do not currently pose a
material risk to monetary or financial stability in the
United Kingdom.”98
In June 2014, the Swiss government affirmatively decided
not to propose any new statutory provisions regarding
virtual currency for the immediate future.
Although a
report by the Swiss Federal Council urged caution when
conducting cryptocurrency transactions, the report
concluded that no new legislation was necessary, in part,
because “the economic importance of virtual currencies
like Bitcoin as a means of payment is fairly insignificant at
the moment and the Federal Council believes that this
will not change in the foreseeable future.”99
On the other end of the spectrum, Russia and Iceland
have each passed laws that are particularly hostile to
virtual currency. Legislation has been introduced in
Russia that would prohibit the distribution, creation and
use of “money substitutes,” which includes virtual
currencies; violators of the law would face criminal
penalties.100 Various sources have suggested that the
legislation will be enacted by the end of 2015.101 Even
though the legislation has not passed, as early as
International Regulatory Landscape Reed Smith LLP 13
. February 2014, Russian authorities warned that the ruble
was the sole currency of Russia, and using virtual
currency as a money substitute was illegal.102 The
Central Bank of Iceland has also declared that neither
bitcoin nor Auroracoin is a recognized currency or legal
tender under Icelandic law, and that the purchase of
virtual currency is restricted under Iceland’s Foreign
Exchange Act.103
Asia
Generally speaking, Asian countries have more stringent
regulations governing virtual currency compared with the
rest of the world. For example, the use of Bitcoin and
other virtual currencies is completely barred in
Bangladesh, and officials from the Bangladesh Bank have
stated that anyone caught using virtual currencies may
be sentenced to up to 12 years in jail under the country’s
strict AML laws.104 In China, while the use of Bitcoin and
virtual currencies by individuals technically remains legal,
its use is difficult if not impossible. This is because the
People’s Bank of China has warned financial institutions,
payment institutions, and third-party payment providers
that they may not accept, use, or sell virtual currencies;
may not generally be involved in virtual currency
transactions; and may not work with virtual currencyrelated businesses.105 The regulatory status of virtual
currency in Thailand is far from clear: in 2013, the Bank
of Thailand informed a virtual currency-based business
that virtual currency activities were illegal in Thailand;
however, one year later, the same bank reportedly
concluded that Thai law does not regulate virtual
currency, but that exchanges still could not operate if
they could not prevent virtual currencies from being
exchanged with currencies other than the Thai Baht.106
On the other end of the spectrum, Japan stated in June
2014 that, despite the fall of Japanese-based bitcoin
exchange Mt. Gox, the country would not move to
regulate virtual currencies in the immediate future.107
Finally, several other Asian countries, such as India and
Singapore, are pursuing a more cautious approach
similar to Europe and the United States, where they are
seeking to adapt already existing laws to cover virtual
currencies.108
The Americas
Outside of the United States, two countries in the
Americas hold “first” status in digital currency regulation:
Canada became the first country in the world to enact a
national law specifically regulating virtual currencies,
while Ecuador became the first country to issue its own
state-backed digital currency.
In June 2014, Canada amended its Proceeds of Crime
(Money Laundering) and Terrorist Financing Act to
include provisions specifically governing virtual
14 Reed Smith LLP International Regulatory Landscape
currencies from an AML perspective.109 Pursuant to the
amended statute, dealers in virtual currencies would be
subjected to the same regulations as money services
businesses.110 The implications of this classification are
that those dealing in virtual currencies would be
required to register with the Financial Transactions and
Reports Analysis Centre of Canada (“FINTRAC,” similar to
FinCEN in the United States), and abide by various
regulatory obligations surrounding recordkeeping,
suspicious transaction reporting, and verification
procedures, among others.111 Under the revised
statutes, banks are also prohibited from opening or
maintaining banking relationships with unregistered
businesses that are now classified as money services
businesses on account of dealing in virtual currency.112
Second, in 2015, Ecuador became the first nation to
issue its own, state-sponsored digital currency—the
dinero electrónico—that is officially legal tender in the
country alongside the U.S.
dollar.113 However, although
the Ecuadorian government’s own digital currency is legal
tender, Ecuador has explicitly banned Bitcoin, Ripple, and
other types of virtual currency.114 Bolivia has a similar
ban on virtual currency, but has not issued its own digital
currency as a substitute.115 Perhaps because of these
bans issued by its South American neighbors, authorities
in Argentina and Brazil have issued warnings about the
risks of using virtual currencies not recognized as legal;
however, these countries have not banned virtual
currency themselves.116
Africa
There is limited data on the regulation of virtual currency
throughout Africa.117 In South Africa, a joint statement
issued by the National Treasury, the South African
Reserve Bank, the Financial Services Board, the South
African Revenue Service and the Financial Intelligence
Centre confirmed that “[c]urrently in South Africa there
are no specific laws or regulations that address the use
of virtual currencies.”118 Therefore, the use of the virtual
currency in the country is generally permissible.
However, the same authorities warned against the risks
of virtual currency, and also clarified that because of this
unregulated status, “no legal protection or recourse is
afforded to users of virtual currencies,” and “virtual
currencies cannot be classified as legal tender as any
merchant may refuse them as a payment instrument.”119
. Insuring Bitcoin and Bitcoin Business
Companies that service the Bitcoin industry and its
holders face risks unique to the bitcoin120 market, as well
as to the financial services market generally. Thus, key
questions for potential policyholders include how, if at all,
insuring bitcoin is different from insuring other
currencies? What insurance products currently exist that
may cover bitcoin holders, servicers, and third-party
vendors, and is the industry developing new types of
coverage specific to bitcoin? And, to date, how has the
insurance industry responded to claims made under
those insurance policies? This chapter examines these
questions and identifies practical concerns and tips for
policyholders.
Does Bitcoin Raise Unique Insurance and
Underwriting Issues?
Bitcoin is both an asset akin to currency and a protocol
for digitally recording transactions. Viewed from this
(simplified) perspective, insuring bitcoin holders, storage
providers, exchanges, or related companies should be
no different in terms of risk than any other business that
safeguards or transfers an anonymous commodity, like
cash, or that must protect its trade secrets or sensitive
digital information. A variety of “traditional” insurance
coverages exist, for example, to insure financial
institutions and technology companies and their
management, including network security and privacy
liability (cyberliability) insurance, financial institution
bonds and commercial crime insurance, directors’ and
officers’ liability (D&O) insurance, and professional
liability (E&O) insurance.
At least one court even has
characterized bitcoin as equivalent to traditional assets
like “money” or “securities,”121 suggesting that traditional
insurance ought to respond to risks faced by the Bitcoin
industry, just as insurance responds to similar risks in
more established financial and technology industry
sectors.
But novel issues abound, as Bitcoin (and its derivatives)
feature several unique characteristics. Unlike most
“traditional” currencies, bitcoin requires no financial
institutions to issue new currency and no banks to store
it, and transactions may be anonymous and are nonreversible. Also, because Bitcoin is decentralized, and its
software is open-source, there is limited control over the
currency or technology beyond a core group of
developers and dedicated individuals.
Thus, Bitcoin
raises potentially unique issues with regulation,
information security, price volatility, and reputation.
Regulation
As discussed in Chapters 3 and 4, governments have
taken divergent approaches to regulating Bitcoin, with
some outright banning cryptocurrencies altogether.122
The possibility remains that governments will impose
substantial regulatory burdens or penalties on
companies operating within the industry, including the
risk of fines, application of anti-money laundering laws,
and rigorous oversight by government agencies that
range in focus from consumer protection to
commodities regulation.
Information Security
The cryptocurrency industry is seeking consensus on
how best to secure Bitcoin and other cryptocurrencies,
and the companies that service cryptocurrency holders,
including storage companies, trading platforms, and
exchanges. Ownership of cryptocurrency is synonymous
with knowing a private “key” associated with an address
on the public chain of title (the “blockchain”). To conduct
transactions, owners may use the services of a company
acting as an intermediary to secure their private keys and
run the software needed to spend bitcoin.
These
companies take varied approaches to securing private
keys in their possession. Some put private keys in “cold
storage,” meaning keys are saved in computers not
connected to the public Internet. Other companies
utilize (among other methods) “multi-sig” technology that
requires knowledge of multiple keys before a transfer of
bitcoin is possible, with the company holding one key,
the owner another, and a third retained offline as a
backup.
Thus, neither the industry serving bitcoin users
nor the users of the currency have yet identified
preferred standards of asset protection.
Price Volatility
Bitcoin has risen and fallen in price dramatically since its
introduction. Price volatility raises issues with respect to
the financial strength of insured companies, the severity
of the risks they face, and how to predict or quantify
losses.
Reputation Concerns
Bitcoin’s infancy has been plagued by an association with
criminal activity. Media reports often discuss Bitcoin in
connection with cybercrime, including schemes to
defraud, phishing attacks, and theft.
Bitcoin has also
reportedly been used by criminals as an anonymous
means of payment for drugs, extortion schemes, and
other illegal activities.
Insuring Bitcoin and Bitcoin Business Reed Smith LLP 15
. Given these issues and concerns, what can companies
operating within the bitcoin economy expect? In short, a
rigorous insurance underwriting process, and potentially
a rigorous claims process when losses ultimately occur.
Insurers may assess a company’s current practices and
protocols concerning data, network and privacy security,
physical protections for data held in cold storage, and
breach or loss response. In the event of a loss,
insurance policies may require rapid identification of the
breach or loss, collection and preservation of
information, mitigation of any damages or losses, and
prompt notification to the insurance carrier. Due to the
sensitivity of the information a policyholder may be
required to share with insurers, both during the
underwriting process and in the event of a loss,
companies should insist on signing strong confidentiality
agreements with insurers and brokers. Coverage
counsel can help policyholders navigate these and other
related issues both during placement of coverage and
after a loss occurs.
Potential Insurance Coverage Under
Traditional Policies
Although Bitcoin raises a number of novel issues,
insurance companies may seek (and have sought) to
insure the risks arising from this technology with wellestablished forms of coverage.
Some insurers also have
begun developing hybrid forms of insurance coverage to
address both the more traditional risks associated with
the industry and the unique aspects of bitcoin and
bitcoin technology.
Cyberliability
Cyberliability insurance is designed to address first-party
losses and third-party liability as a result of data security
breaches and the disclosure of or failure to protect
private information. It commonly insures against (or
helps defray) the cost of misappropriated data,
investigating a breach, responding to regulators,
defending against lawsuits, notifying affected persons,
restoring or recreating any lost data, and paying
damages and settlements, among other expenses.
Cyberliability policies often are negotiable and may be
tailored to a particular company or industry.
Ideally, a cyberliability policy intended to cover Bitcoin or
Bitcoin-related operations should be drafted broadly
enough to cover issues unique to the currency and
technology. The policy thus might insure against liability
related to the company’s storage or exchange of bitcoin,
corruption or breach of its associated technology, or
losses due to a compromised vendor.
The definition of a
liability event should be broad enough to include
disclosure of or damage to the types of confidential
information unique to Bitcoin, including users’ private
keys. Security concerns or vulnerabilities particular to
16 Reed Smith LLP Insuring Bitcoin and Bitcoin Business
bitcoin and bitcoin technology also should be addressed
where possible, including the generation of flawed keys,
transaction malleability attacks, 51 percent attacks
intended to manipulate the blockchain, sybil attacks, and
distributed denial of service attacks.123
Financial Institution Bonds and Commercial Crime
Policies
These policies insure against first-party losses caused by
certain types of criminal, fraudulent or dishonest activity,
including employee dishonesty, fraud, forgery, and
extortion. Many bonds and commercial crime policies
contain coverage for computer crimes and frauds that
directly result from the use of a computer and result in
the transfer of money, property, or securities from within
the company to parties outside of the company.
Businesses that use, keep, or perform services related to
bitcoin should ensure that “bitcoin” is included in the
definition of “money,” “currency,” “property” or any
related terms or definitions that identify covered types of
loss.124 Bitcoin transactions may be conducted “peer-topeer,” meaning the buyer and seller do not need to use a
central exchange.
Companies should examine their
potential exposure to losses arising from peer-to-peer
transactions, because at least one insurer has publicly
stated that peer-to-peer transactions are not covered
under its commercial crime policy form.125
Social engineering and “phishing” attacks also are a
threat to a Bitcoin business. A bad actor could seek to
convince an employee that they are conducting a
genuine transaction or sharing private information with a
trustworthy recipient, when the employee is in fact an
unwitting intermediary in a scheme to defraud. Social
engineering attacks can implicate the “direct” causation
and intent standards in many bonds and commercial
crime policies.
Traditional financial institution bonds
cover only losses “directly caused” by a covered activity.
The “direct loss” standard is not uniformly interpreted by
the courts and is a frequent source of insurance
disputes. Some courts hold that the “direct loss”
standard is equivalent to proximate causation under
traditional tort law, but others hold that “direct loss”
means that there can be no intervening cause between
an action intended to cause harm and the harm itself. If
the latter interpretation applies, it may be difficult to
obtain insurance proceeds for losses caused by a social
engineering or phishing attack on a bitcoin company.
A recent lawsuit filed by bitcoin payment processor
Bitpay, Inc.
against its commercial crime insurer
illustrates this issue. 126 After a phishing attack
compromised the email account of a Bitpay executive,
the hacker used information collected from the
executive’s email to induce the company to transfer
funds to an ostensible customer wallet that was, in fact,
. controlled by the hacker. Bitpay’s commercial crime
insurer denied coverage, asserting that because the
Bitpay executive acted as an unwilling intermediary in the
scheme, the loss was not “directly caused” by the activity
of the hacker. (Bitpay’s lawsuit remains pending as of
this writing.)
In addition, many policies require “manifest intent” by an
employee before a loss caused by employee dishonesty
is insured, a phrase sometimes interpreted by courts to
mean that an employee must not only intend to
personally gain from his or her dishonesty, but also to
intend to harm the company. Thus, an insurer may
assert a defense to coverage if a defalcating employee’s
intent was directed at the bitcoin holder, not the
company.
D&O Insurance
D&O insurance is designed to protect a company’s
directors and officers, and often to a more limited extent,
the company, against third-party liability.
D&O policies
commonly insure individual directors and officers when
they cannot be indemnified by their companies (“Side A”
coverage), the company when it pays indemnification to
its directors and officers (“Side B” coverage), and the
company in connection with lawsuits alleging violations
of the securities laws (“Side C” coverage). Monetary
damages may be covered, but property damage
generally is not. D&O insurance often can be negotiated.
Although a variety of D&O policy provisions should be
tailored to Bitcoin-related risks, three are of particular
note.
First, any Bitcoin-related company should ensure
its policy will cover securities lawsuits triggered by a loss
of bitcoin or damage to the company’s bitcoin operations.
Second, given the prevalence of criminal activity related
to the currency and technology, as well as the uncertain
regulatory environment, the insurance policy should
clearly insure the costs of cooperating with government
investigations, inquiries, and any administrative
proceedings related to Bitcoin. Finally, companies
should pay attention to any exclusion for loss arising
from professional services provided by the company.
E&O Insurance
E&O insurance is designed to protect individuals and
companies from liability for mistakes, omissions, and
other errors made in the performance of a professional
service. E&O polices can be tailored to specific risks and
are frequently negotiable.
Every company that provides
services related to bitcoin in return for a fee – whether
they host or maintain customer “wallets,” operate
exchanges, facilitate transactions, or provide any of the
myriad services relevant to the industry – can potentially
benefit from having E&O insurance. A lawsuit accusing a
company of an error, even if frivolous or baseless, could
result in substantial legal expenses and reputational
damage.
Would a traditional E&O policy cover a financial
institution utilizing new bitcoin technology, such as a
financial institution implementing blockchain technology,
to record and maintain the ledger of private stock
transactions? Although many E&O policies broadly
define what constitutes a covered “professional services,”
E&O policies are not entirely uniform among different
insurers and different industries and may be tailored to
specific risks, and thus the definition of “professional
services” may or may not automatically include such
services. For instance, many E&O policies issued to
financial institutions define “professional services” simply
as those services provided by the insureds to a customer
or client for a fee or other form of compensation or
services.
In some cases this language may be read to
capture all such services provided by the policyholder
(i.e., any service performed for a customer for a fee), but
for other policyholders, this generalized description of
“professional services” may be tied, either explicitly or
implicitly, to particular representations made in the
company’s application for the insurance, or in the
company’s public filings with the SEC or other regulators.
Further, the definition of “professional services” in some
E&O policies may incorporate or list specific types of
services performed by the particular policyholder.
Accordingly, companies performing Bitcoin-related
services should carefully review the way in which their
E&O insurer defines covered professional services to
decrease the possibility of a coverage dispute in the
event of a loss.
Kidnap and Ransom (“K&R”) Insurance
K&R coverage insures an individual or company from
loss in the event the insured, an employee, or some
other identified person is kidnapped, detained, or
ransomed. K&R coverage is an indemnity product,
meaning that the ransom money must first be paid
before the insurer will provide reimbursement.
According to recent media reports, bitcoin has emerged
as a preferred currency for kidnappers and extortionists.
As such, companies should ensure, where possible, that
its K&R coverage allows for ransoms and extortion
payments to be paid in bitcoin. For example, any
definition of “money” or “currency” in the policy should
expressly include “bitcoin.”
Bitcoin-Specific Insurance
Several major insurers reportedly have developed
specialized insurance products for the bitcoin market.
Although the details, terms and conditions of these
policies are not widely known, it has been reported that
at least one major carrier has created an E&O policy with
the privacy and data protection elements of cyberliability
Insuring Bitcoin and Bitcoin Business Reed Smith LLP 17
.
coverage, commercial crime protection, and deposit
protection;127 and another has developed a “new” type of
commercial crime coverage specific to bitcoin. 128 Other
companies have created captive insurance funds to
protect their customers instead of turning to insurance
companies. 129 As this nascent industry and its
technology continues to develop, it remains to be seen
how these initial insurance products will respond to the
unique risks posed by bitcoin and the industry that
serves the currency and its users.
The Bottom Line
Bitcoin has created a small but growing industry focused
on, among other things, securing users’ private keys,
facilitating transactions, running bitcoin exchanges, and
trading bitcoin futures or swaps. In order to increase
customer and investor confidence, and to free capital to
18 Reed Smith LLP Insuring Bitcoin and Bitcoin Business
grow their businesses, companies providing Bitcoinrelated services may, like the financial services industry
supporting “traditional” currencies, look to transfer their
risk of liability and loss through the purchase of
insurance.
Until insurance policies and products
specifically tailored to the industry are widely available to
companies providing Bitcoin-related services, companies
should review their current insurance coverage to assess
how and to what degree insurance will respond in the
event of common claim scenarios. Companies
purchasing either traditional policies or Bitcoin-specific
coverage for the first time should carefully review the
terms and conditions of any proposed coverage, and
consult with a reputable broker and policyholder
coverage counsel when comparing different policy forms
and negotiating important changes and enhancements
where possible.
. Applications in Capital Markets
Although it was developed in the context of creating
cryptocurrency, the blockchain has the potential to have
a major impact on both financial institutions and financial
transactions involving fiat currency. In fact, few Bitcoinrelated developments generated by financial institutions
have to do with trading bitcoins or conducting
transactions involving other cryptocurrencies. Instead,
these institutions are applying the technology behind
bitcoin—the blockchain—to numerous types of other
financial innovations that do not involve any type of
cryptocurrency.
Already, banks and financial institutions have met to
discuss how to respond to and/or utilize this technology,
and several financial institutions are performing in-house
experiments and projects seeking to take advantage of
the blockchain’s benefits.130 Several tech startups, such
as Digital Asset Holdings, led by Blythe Masters, and R3,
which is supported by JPMorgan, Barclays, Credit Suisse,
and Goldman Sachs, among others, are also exploring
the blockchain space, and seek to find ways to
implement blockchain technology into everyday banking
and financial transactions.131
Some analysts are hailing blockchain technology as
transformative, with Accenture describing it as possibly
the “critical backbone” of the future capital markets
infrastructure,132 and the New York Times describing it as
a “fundamentally new way” of transacting and
maintaining records.133 Financial industry consultancy
firm Greenwich Associates interviewed 102 institutional
financial professionals in mid-2015; of those surveyed,
94 percent responded that they believed that blockchain
technology could be applied in institutional markets, and
almost half reported already being in the midst of
reviewing the technology within their firms.134
Spending by capital markets firms on research and
development in the technology will more than double
from $30 million in 2014 to $75 million in 2015,
according to consultancy firm Aite Group.135
While there are those who are more skeptical, industry
professionals, including major financial players, have
demonstrated a keen interest in applications of
blockchain to their industry.
Greater Efficiencies
Transactions involving the blockchain have the potential
to be significantly more efficient. This increased
efficiency will come in the form of quicker settlement,
improved accuracy, lower error rates, automated
settlement, and significantly less reliance on third parties
for post-trade settlement.
This may lead to lower costs
for all parties involved.
One of the most exciting potential applications of the
blockchain in capital markets is the possibility of using it
to eliminate the cost and time of clearing and settling
financial assets. Because the blockchain is decentralized
and is not maintained by any one party, two parties can
exchange an asset or information directly with each
other without the use of a third party validating the
information in a near instantaneous settlement. In the
blockchain, the assets can be tied to individuals, with no
need for institutional custodians.
This development could save Wall Street banks and
investors billions of dollars by radically reducing a
transaction’s lifespan, as it would free up capital that is
otherwise pledged to back trades until they are settled.
Typical securities trades take two to three days to
settle,136 and the potential savings for other
transactions is even greater: for example, the average
bank loan took nearly 23 days to settle in 2013.137
Initially, the blockchain is most likely to impact asset
transactions where there is no central clearing or trading
authority, such as transactions involving FICC derivatives,
syndicated loans, and private investments.
NASDAQ has
already announced that it is looking to implement the
blockchain in connection with the trading of private
companies, and to replace paper trading for these types
of transactions.138
Furthermore, the security provided by the blockchain
may have an even greater impact on markets with high
transaction volume, but less trading infrastructure in
place, such as loans and private over-the-counter
derivatives that cannot be backed by clearinghouses.
More Security and Transparency
Many analysts believe that the blockchain can make
financial transactions more secure. Because the
blockchain is not controlled by a central party, but
instead involves decentralized control, the blockchain is
less vulnerable to (if not immune from) cyberattack. The
blockchain cannot be lost or corrupted by participants,
and thus counterparty risk in transactions is significantly
reduced.
Because of the public nature of the blockchain, and the
completeness of the information contained in its ledger,
the blockchain also has the future potential to more
easily facilitate data-sharing for KYC and AML purposes,
trade surveillance, regulatory reporting, collateral
Applications in Capital Markets Reed Smith LLP 19
.
management, and perhaps even real-time auditing of
transactions.
However, despite the blockchain being publicly available
and easily shared among parties, various identifying
information about parties making transactions may be
hidden and made private in certain circumstances. There
is thus a means to limit privacy risks in conjunction with
the improved transparency.
Imagine also reconfiguring on the blockchain various
protocols widely used in the capital markets, such as
SWIFT (a communications platform designed by the
Society for Worldwide Interbank Financial
Telecommunications to facilitate the transmission of
information about financial transactions), or FIX (a
trading platform for communicating trade information
based on the Financial Information eXchange Protocol).
With the blockchain’s ability to record the complete
history of all transmissions, disputes or errors typically
lost in communications will be minimized, if not
eliminated.
“Smart Contracts”
Finally, the blockchain may offer improved contractual
performance. Innovators are currently working to
develop “smart contracts,” where the terms of contracts
may become automated and agreed upon using
computer protocols within the blockchain.
Potential Risks
Although the blockchain has the potential to provide
tremendous benefits to financial institutions and
transacting parties more generally, widespread use of
this technology does not come without risks and
potential issues.
First, as with the implementation and adoption of any
new technology across a space as complex and massive
as the capital markets infrastructure, there are likely to
be hiccups and growing pains along the way. It is difficult
to predict the immediate impact that any glitches in
blockchain adoption might have on individual
transactions, or the future impact of those glitches on
future adoption of the technology.
20 Reed Smith LLP Applications in Capital Markets
Second, some question whether the blockchain in its
current technological state would be able to handle
transactions in data classes with particularly high volume
and speed requirements.
Some analysts are skeptical as
to whether the blockchain can be updated sufficiently
frequently to be useful in such transactions.
Third, as discussed elsewhere in this paper, there are
numerous unanswered questions as to how regulators
across the globe will react to the blockchain and virtual
currencies more generally. Regulators have still not yet
caught up to the current technology, and when they do,
these regulations could have a significant impact on the
ability of financial institutions and other parties to
implement blockchain technology into everyday financial
transactions.
Finally, whether blockchain technology will impact capital
markets will depend on the use of the technology by
major financial institutions, and the extent to which these
institutions develop the technology. Ironically, although
cryptocurrencies were developed in the hope of
reducing dependency on banks and other major financial
institutions, whether these same institutions cooperate
in instituting the technology will play a role in
determining the impact that the blockchain has on
capital markets.
Conclusion
Despite the potential downsides, the key attraction to
blockchain technology for industry professionals is risk
reduction.
The blockchain offers the potential to
improve the current infrastructure of financial
transactions in significant ways: by making transactions
more efficient and more secure, providing more
transparency and regulatory control, and improving
contractual performance. In addition to highly
capitalized start-ups in this rapidly developing field,
numerous major financial institutions have been
spending significant resources on understanding and
developing relevant applications.
. Bitcoin, Privacy, and Reidentification
As one paper noted, “anonymous digital cash is another
state-of-the-art technology for Internet privacy. As many
observers have stressed, electronic commerce will be a
driving force for the future of the Internet. Therefore, the
emergence of digital commerce solutions with privacy
and anonymity protection is very valuable…”139 Since the
paper in question, Privacy-enhancing technologies for
the Internet was published in 1997, the authors thought
not of Bitcoin but of a predecessor, DigiCash's ecash.
However, the paper identified risks to privacy in using
anonymous digital cash that have only grown:
Of course, the DigiCash protocols only
prevent your identity from being revealed
by the protocols themselves: if you send the
merchant a delivery address for physical
merchandise, he will clearly be able to
identify you. Similarly, if you pay using ecash
over a non-anonymized IP connection, the
merchant will be able to deduce your IP
address.
This demonstrates the need for a
general-purpose infrastructure for
anonymous IP traffic…In any case, security is
only as strong as the weakest link in the
chain.140
Bitcoin has been described as “anonymous but not
private: identities are nowhere recorded in the Bitcoin
protocol itself, but every transaction performed with
bitcoin is visible on the distributed electronic public
ledger known as the block chain.”141 In addition, an
individual Bitcoin user may use one (or very many) public
keys (sometimes referred to as a “bitcoin address”) to
engage in transactions. These public keys do not identify
individual users, and without additional data or analysis,
one cannot determine whether two (or more) public keys
are linked to the same user. Therefore, the Bitcoin
protocol theoretically provides for anonymity (but not
privacy) in transactions because the blockchain does not
involve recording any identifying information to individual
public keys.
However, in practice, it may be difficult to maintain one’s
anonymity when using Bitcoin.
Some chinks in the armor
of privacy when using Bitcoin are akin to those described
22 years earlier as to DigiCash. Some Bitcoin users
voluntarily disclose their public keys; in so doing, they
may either intentionally or unintentionally allow others to
link identifying data with these public keys. Those who
are able to link public keys with this outside identifying
information may have the ability to then analyze the
blockchain and potentially determine the identity of the
user.
This identifying data does not necessarily have to
be as specific as a person’s name, address, or phone
number. It could be something as seemingly innocuous
as the knowledge that a particular user made a purchase
with a particular business around a certain time.
For example, at the onset, many users purchase bitcoin
through an online wallet or exchange service. That wallet
or exchange service has the personal information of the
purchaser.
Bitcoin for these users is effectively no more
anonymous than a bank account, although
this loss of anonymity takes place at the point
of entry into the currency and is not a feature
of the bitcoin protocol itself.
Further, some users voluntarily reveal or disclose their
public keys, whether publicly (as may be the case for
businesses accepting bitcoin as payment), or through
blockchain.info, or more privately in forums, signature
lines in internet posts, or in forums.
In this respect, one
may think of a bitcoin public key in a way similar to an
email address: some email addresses may be relatively
anonymous in nature (for example, an email that does
not reveal one’s name or initials), but one may of course
still choose to reveal that email address to acquaintances.
In addition, “[e]ven supposing one manages to acquire
bitcoins without giving up personal information, one’s
real-world identity can still be discovered in the course of
transacting bitcoin within the network.”142 As discussed
above, when outside information becomes linked with a
particular public key, there is a risk that reidentification
may occur through various types of behavior-based
clustering analysis of the blockchain, and in some cases,
analysis of the IP addresses of nodes adding blocks to
the blockchain.
In the case of Bitcoin, there is not only the risk that a
delivery order to a physical address will lead to
reidentification. There is also, in the distributed ledger
itself, a large amount of public data with respect to
transactions made with the bitcoin currency, leading one
author to note:
A complementary source of potentially
deanonymizing information is available to
every computer that participates in the
decentralized transaction network by hosting
a bitcoin node. This information is the set of
IP addresses of the computers that announce
new bitcoin transactions…
Bitcoin, Privacy, and Reidentification Reed Smith LLP 21
.
An example of this kind of IP address
deanonymization made public is
blockchain.info, which discloses the IP
address of the first node to report a
transaction to its servers. The information is
only as reliable as the web site’s node
connectivity: with a declared 800–900
connected nodes at the time of writing, it is
probably not enough to reliably pinpoint the
originating IP in all cases.143
Some of the concerns surrounding the privacy and
pseudonymity of Bitcoin are similar to the concerns of
pseudonymity raised in other industries and other
contexts. For example, the National Institute for
Standards and Technology (NIST) has issued standards
regarding pseudonymity and deidentification. The NIST
standards concern a different type of pseudonymity
issue than is present in Bitcoin.
Specifically, the NIST
standards concern data sets that have been stripped
from personally identifiable information, and the risk of
re-identification from those data sets. These standards
are aimed at companies managing individuals’ sensitive
information so as to not inadvertently reveal their
identities. In contrast, the “rules of the game” concerning
Bitcoin pseudonymity are more well known and “spelled
out.” Further, Bitcoin users have more control over
whether they made be re-identified, and can take various
actions to greater maintain privacy (however, this
increased privacy may lead to higher transaction costs).
NIST defines pseudonymization as a “specific kind of deidentification in which the direct identifiers [like names or
account numbers] are replaced with pseudonyms.” 144
NIST defines “re-identification risk” as “the measure of
the risk that the identities and other information about
individuals in the data set will be learned from the deidentified data.”145 The factors that determine
reidentification risk include: “the technical skill of the
data intruder, the intruder’s available resources, and the
availability of additional data that can be linked with the
de-identified data.”146
The report includes a number of highly public instances
in which pseudonymized identities were re-identified
based on ancillary information, from movie choices to
medical outcomes to location data.147
22 Reed Smith LLP Bitcoin, Privacy, and Reidentification
However, as NIST warns, “In many cases the risk of reidentification will increase over time as techniques
improve and more background information become
available.”148 In the case of distributed ledger technology,
the permanence of transaction history ensures that the
transaction history available to analyze continues to
expand even as the techniques to do so improve over
time.
NIST’s concern regarding reidentification risk is mirrored
internationally.
For example, under European privacy
law, a pseudonym is personal data under specific
standards set forth by the Article 29 Working Group. 149
“Pseudonymity is likely to allow for identifiability, and
therefore stays inside the scope of the legal regime of
data protection.”150 The Article 29 Working Group lists as
a “common mistake”:
Believing that a pseudonymized dataset is
anonymized….Many examples have shown
that this is not the case; simply altering the ID
does not prevent someone from identifying a
data subject if quasi-identifiers remain in the
dataset, or if the values of other attributes are
still capable of identifying an individual.151
The paper identifies as weaknesses of the
pseudonymous approach, “the user using the same key
in different databases,” as well as storing the key to reidentify in the same place as less secure data. “If the
secret key is stored alongside the pseudonymized data,
and the data are compromised, then the attacker may be
able to trivially link the pseudonymized data to their
original attribute.”152
Of course, every form of extensive activity is potentially
subject to re-identification.
This theoretically includes
Bitcoin activity, in which re-identification is theoretically
possible using information from the blockchain.
Nevertheless, those using bitcoins and distributed ledger
technology should be aware of the already-identified
risks of reidentification inherent in the current model,
and take steps to reduce such risks by protecting
pseudonyms used and linkable public information
. Intellectual Property
While Bitcoin made the blockchain famous, the benefits
of a secure distributed ledger are being implemented
across many fields. Ancillary technologies are being
invented to improve and expand cryptocurrency services,
improve block mining, and implement the blockchain in
new ways. New software is being developed to advance
the technology in even more directions. As with many
technologies, the intellectual property rights surrounding
blockchain technologies are quickly evolving and
maturing—and becoming less open.
Satoshi Nakamoto published his idea for the blockchain
underlying Bitcoin, placing the idea into the public
domain for anyone to implement.
And Bitcoin software
is distributed under an open source license that allows
others to freely use, modify, and share the software. The
Hyperledger Project proposes a similar model. But what
does that really mean for companies involved in the
Bitcoin industry? What are the specific terms of the open
source licenses? Are there any intellectual property (IP)
rights, such as patent rights, that fall outside of an open
source license? And what IP rights come into play for
companies developing or using applications of the
blockchain separate from Bitcoin or Hyperledger? This
chapter examines these questions and identifies
emerging trends in blockchain IP.
The IP landscape
developing around Bitcoin and blockchain technologies
can be a minefield. Stakeholders and market entrants
need to know how to navigate the risks and protect their
contributions.
Bitcoin’s Open Source License
The Bitcoin Project is released under the MIT License.
The MIT License grants the rights to any person with a
copy of the licensed software the rights to copy, modify,
merge, publish, distribute, sublicense, and/or sell copies
of the software. The only condition the MIT License
places on copies and derivative works is that its copyright
notice and terms must be included in all copies or
substantial portions of the software.
Companies
involved in the Bitcoin industry can thus freely copy and
use Bitcoin software.
Bitcoin has sparked development of third-party software,
other cryptocurrencies, and other applications of
blockchain technology. The Bitcoin Project encourages
innovation, and the MIT License permits development of
software and new technologies incorporating Bitcoin
code. The license even allows for proprietary software to
use Bitcoin software.
Some Bitcoin-based software
therefore may not be freely modified or copied.
Companies utilizing Bitcoin software or other open
source blockchain software therefore need to be aware
of the terms of the license to the specific software they
are using to understand their rights and potential
liabilities.
Other Blockchain Application Licenses
Many promising new technologies are developing based
on the blockchain idea and its permissive license. The
Hyperledger Project, for example, is a cross-industry,
open source collaborative effort created to advance
blockchain technology. Its stated mission is to create an
enterprise grade, open source distributed ledger
framework and code base, upon which users can build
and run robust, industry-specific applications, platforms
and hardware systems to support business transactions.
While the Hyperledger Project is open source, like the
Bitcoin Project, its open source license is more restrictive
than the MIT License under which the Bitcoin software is
distributed.
Inbound code contributions to the
Hyperledger Project and outbound code will be made
available under the Apache License, Version 2.0. The
Apache License V2.0 grants broad rights, but includes
additional notice requirements and restrictions on
derivative works not included in the MIT License. The
Apache License V2.0 also grants a patent license from
each contributor with various restrictions.
Companies
using or developing blockchain technologies that are
unaware of the specific terms of relevant licenses risk
infringement.
The Rise of Blockchain Patents
The growth of Bitcoin has sparked innovations in
supporting and complementary technologies. More
innovation is expected as the applications of blockchain
technology beyond cryptocurrencies are explored. A
sharp increase in patent applications in recent years
evidences both the rate at which the technology is
developing and the desire of stakeholders to maintain
their competitive advantage by protecting their
inventions.

Social Impact
Despite being an emerging technology, Bitcoin has been
the focus of several charity and social impact projects
since its inception. While the use of bitcoins to fund
charity projects and for remittances has garnered recent
attention, there has been less focus on how the
blockchain algorithm itself might be used in applications
with a social impact. This chapter describes some
successful applications of the blockchain algorithm to
problems in the social responsibility space, and
describes the wide opportunity in this area.
Lowered Transaction Fees Mean More
Money for Causes
The immediate appeal of cryptocurrencies in the context
of international aid is the potential to lower transaction
and currency exchange fees, especially for smaller
donation amounts. Donors can send small donations of
fiat currency, which are converted to bitcoin at an
approximately 1 percent transaction fee, which are in
turn sent to an aid organization’s digital wallet for
conversion into a local currency of choice.
By reducing
these fees, organizations can make more out of smaller
donations.
ChangeTip, a micropayment service, partnered with
Direct Relief to enable donors to purchase $5 prenatal
vitamin supplements for mothers in the developing
world.153 ChangeTip channeled these small donations
through bitcoin, cutting down on fees that would have
made such small donations impracticable.
Greater Transparency
The Bitgive Foundation, partnering with Factom, recently
launched the Donation Transparency Project, which aims
to track donations and expenditures in aid projects using
the blockchain algorithm.154 The platform aims to add
transparency and traceability to international aid
organizations, so that donors can see the impact of their
giving and make informed decisions about effective aid
organizations. Similar applications could improve the
ability of governments and international charities alike to
track international development spending, reduce
corruption, and analyze trends across projects.
Access to Financial Services
Applications of the blockchain algorithm have much to
offer the 2 billion adults in the world who lack a bank
account. Much of the attention has focused on using
cryptocurrencies to send remittances, which have
typically been subject to high fees.
However, while much
has been said about the potential for Bitcoin to reduce
fees for remittances,155 building an end-to-end money
transfer system using cryptocurrency has remained
difficult.
The most successful applications pick a single country or
region and focus on the so-called “last mile,” where the
incoming money transfer is converted to cash for its
recipient.156 For example, BitPesa focuses on converting
bitcoins to Kenyan or Tanzanian shillings and depositing
that local currency to a mobile money number.157 By
relying on the pre-existing mobile money wallet system
in use by many Kenyans and Tanzanians, BitPesa is able
to sidestep the complicated international money transfer
system that has made a general-purpose bitcoin-based
remittance system so elusive. The Philippines, which is
the world’s third-largest recipient of remittances, has
also seen significant innovation in using bitcoin to send
money into the country. Several startups focus on
converting bitcoins to Philippine pesos and making cash
available to remittance recipients in partnership with the
ATM networks, convenience stores, and pawnshops that
customers already use.
Much like with international aid, the blockchain algorithm
has more to offer than simply reducing fees for money
transfers.
Coins.ph, one of the remittance startups in the
Philippines highlighted above, has introduced a new
service called Teller.158 Teller, in startup nomenclature, is
“Uber for ATMs,” in that the Teller application connects
customers to pre-screened tellers who can take or
distribute cash in exchange for bitcoins. Tellers and
customers are kept accountable through a two-way
reviewing system, and its inaugural tellers are the same
convenience stores and pawnshops that customers
currently use for remittances. Because the financial
transaction itself is secured by the blockchain, Teller can
focus on the security and availability of only one step of
the process: the exchange of an electronic balance for
cash.
Using the blockchain, in other words, makes it
possible to serve the unbanked where they already are.
Financial Empowerment
One of the defining features of blockchain and
cryptocurrencies is democratization. For those who do
not have control over their financial destinies under
traditional financial systems, the blockchain opens up
significant opportunities. For example, two projects
started by Afghan entrepreneur Fereshteh Forough use
bitcoin to pay Afghani women for work they complete as
they learn skills for the digital economy.
The Digital
Citizens Fund159 builds women-only computer centers to
teach young women word processing, presentation,
financial and Internet-based tasks, while Code to
Social Impact Reed Smith LLP 25
. Inspire160 similarly teaches young women computer
programming. Both organizations use bitcoin to pay their
students, not only because of the number of unbanked
people in Afghanistan, but also because of the cultural,
legal, and safety issues associated with giving women
cash in that country.161 With bitcoin, these young
Afghani women can exercise a measure of control over
their financial futures.
Improving Governance and Minimizing
Corruption
As The Economist phrased it, blockchain’s central
innovation is that it is a “machine for creating trust.”162
An important application area for blockchain, and
perhaps one of the largest opportunities, is modernizing
the way we store and secure information relating to large
groups. For governments, blockchain offers the
opportunity for an open, transparent ledger of public
information with an unchangeable audit trail for every
record. One country, Honduras, is already
experimenting with using the blockchain to store land
26 Reed Smith LLP Social Impact
title records.163 The current land title system is not only
incomplete, but it is also subject to near constant
corruption and manipulation.
The government of
Honduras, working with U.S.-based startup Factom,
hopes to leapfrog current land records techniques to
create an auditable and incorruptible title database.
Future applications of the blockchain algorithm could
offer similarly secure records of procurement activities,
votes, budgeting information, or other government
information.
Summary
The initial successes and challenges of using
cryptocurrencies for social impact projects have inspired
a new wave of innovation focused on blockchain. We
have only scratched the surface of the tremendous
opportunity in this area, as entrepreneurs and
institutions around the world find ways to use the
blockchain algorithm to empower the developing world,
reach those in need, and build a better future for all.
. Closing Note
We trust that by now you have become comfortable, and hopefully even enthusiastic, about the potential
transformative power of the blockchain. Many have compared the development of bitcoin and its underlying
blockchain with the development and adoption of the Internet. At that time, many remained skeptical of the
Internet’s application to financial transactions and the financial world more generally. Today, we cannot imagine an
economy and financial system without the capabilities that the Internet offers.
In five to 10 years, we may be sharing
the same view of the blockchain.
Of course, the development of online transactions and e-commerce has generated numerous unique regulatory and
legal issues for financial institutions and other participants in the financial world. To the extent that the blockchain
will impact the financial system as much as some predict, the technology will similarly generate unique regulatory and
legal issues that our clients must address. At Reed Smith, our focus on client services means staying ahead of the
curve, and advising clients on the potential legal issues surrounding new technology as that technology develops.
As
your business or organization begins to devise strategies regarding cryptocurrencies and the blockchain, the Reed
Smith Blockchain Technology Team and its members across our global offices are always available to advise you on
the legal issues surrounding this exciting new technological development.
There is no doubt in our minds that the blockchain has the potential to effect significant changes in the financial
world, and other industries, by providing the ability to have a transparent, immutable record of a transaction, without
the need for trusted third-parties. As has been discussed throughout this white paper, some of the most exciting
potential applications of the blockchain’s distributed ledger technology arise outside of the cryptocurrency context.
We hope that this white paper has provided you the tools to begin strategizing how the blockchain may impact, or
even transform, your business and operations.
Sincerely,
The Reed Smith Blockchain Technology Team

. Glossary of Terms
51% Attack (also Majority Attack)
Blockchain
The ability of someone controlling a majority of network
hash rate or mining power to revise transaction history
and prevent new transactions from confirming.
A blockchain is a public ledger of all bitcoin transactions
that have ever been executed. The term may also be
used to more generally describe the distributed ledger
technology utilized by the Bitcoin blockchain, even if
applied outside of the Bitcoin context.
Bit
Bit is a common unit used to designate a sub-unit of a
bitcoin - 1,000,000 bits is equal to 1 bitcoin (BTC or B).
This unit is usually more convenient for pricing tips,
goods and services.
Bitcoin
Bitcoin - with capitalization, is used when describing the
concept of Bitcoin, the Bitcoin protocol, or the entire
network itself, e.g., "I was learning about the Bitcoin
protocol today."
bitcoin - without capitalization, is used to describe
bitcoins as a unit of account, e.g., "I sent 10 bitcoins
today." It is also often abbreviated BTC or XBT.
Bitcoin Exchange
A marketplace that allows people to buy or sell bitcoins
using different currencies. Because of the blockchain
algorithm, exchanges can be made securely upon
transfer.
Bitcoin Foundation
An American nonprofit corporation founded in
September 2012 and headquartered in Washington, D.C.,
with the stated mission to “standardize, protect and
promote the use of Bitcoin cryptographic money for the
benefit of users worldwide.” See bitcoinfoundation.org.
BitLicense
A popular name for the business license (and its
associated regulations) issued by the New York
Department of Financial Services (“NYDFS”) under
regulations that came into effect August 8, 2015,
designed for companies engaged in virtual currency
business activities.
Block
A unit of data containing information regarding
transactions that have occurred during a period of time.
A block contains the hash code of the previous block in
the blockchain, a set of transactions that are recorded in
that block, and (if it exists), a reference to the following
block in the blockchain.
28 Reed Smith LLP Glossary of Terms
Block Height
A measure of the age of a digital ledger - the more blocks
that are solved and added to the ledger, the higher the
block height. When choosing between two distributed
ledgers, the one with the higher block height will often be
more secure, and therefore more likely to be accurate.
Byzantine Generals Problem
An abstraction of a computer system problem
concerning the handling of malfunctioning components
that give conflicting information to different parts of the
system:
A group of generals of the Byzantine army
camped with their troops around an enemy city,
and communicate only by messengers.
The
generals must agree upon a common battle
plan; however, one or more of the generals may
be traitors who will try to confuse the others.
The problem is to find an algorithm to ensure
that the loyal generals will reach agreement. It
is shown that, using only oral messages, this
problem is solvable if and only if more than twothirds of the generals are loyal; so a single
traitor can confound two loyal generals. With
unforgeable written messages, the problem is
solvable for any number of generals and
possible traitors.
Bitcoin has frequently been extolled for solving the
Byzantine Generals Problem with its applications of
proof of work and consensus.
Cold Storage
The storage of a reserve of bitcoins or private keys offline,
i.e., disconnected from the Internet, in a physical storage
device such as a hard drive or USB storage device.
.
Consensus
Cypherpunk
A requirement for updating a distributed ledger
requiring a sufficient number of participants to agree
(usually more than half) before accepting the update as
accurate.
An activist advocating widespread use of strong
cryptography as a route to social and political change.
Cypherpunks have been engaged in an active movement
since the late 1980s.
Distributed Consensus
Refers to consensus from the various different
computers making up the network coming to an
agreement without the need for a central
control unit making that determination, and
then broadcasting it to the rest of the network
This is at the crux of how Bitcoin operates.
Federated Consensus
Consensus achieved under what is known as a
federated Byzantine agreement system,
whereby consensus can be achieved from a
“quorum slice,” a subset of trustworthy nodes
that have earned trust organically on the
system over time.
Cryptocurrency
A digital currency in which encryption techniques are
used to regulate the generation of units of currency and
verify the transfer of funds, operating independently of a
central bank.
Cryptography
The use of mathematics to secure information and to
convert data into a secret code for transmission over a
public network. Today, most cryptography is digital, and
the original text (“plaintext”) is turned into a coded
equivalent called “ciphertext” via an encryption algorithm.
Cryptographic Hash Function
A cryptographic hash function is a hash function that
takes an input (or “message”) and returns a fixed-size
alphanumeric string, which is called the hash value
(sometimes called a message digest, a digital fingerprint,
a digest or a checksum).
The ideal hash function has three main properties:
•
It is extremely easy to calculate a hash for any given
data.
•
It is extremely computationally difficult to calculate an
alphanumeric text that has a given hash.
•
It is extremely unlikely that two slightly different
messages will have the same hash.
Digital Currency (also e-Currency, e-Money,
Electronic Cash, Electronic Currency, Digital Cash,
Cyber Currency)
An electronic medium of exchange in which a person can
securely pay for goods or services electronically without
necessarily involving a bank to mediate the transaction.
Digital Signature
The combination of a public key, which identifies you to
others, and a private key, which allows you to access
secret information. Blockchain uses public keys to
identify participants in the ledger, and requires private
keys to allow participants to access assets recorded on
the ledger.
Distributed Consensus
See Consensus
Distributed Ledger
A record of transactions that is shared over a network
with others without a central server or entity that others
must connect to.
Double Spending
Double spending is the result of successfully spending
the same unit of currency (e.g., the same bitcoin) more
than once. Bitcoin protects against double spending by
verifying each transaction added to the blockchain to
ensure that the inputs for the transaction had not
previously been spent.
Federated Consensus
See Consensus
Fork
When miners produce simultaneous blocks at the end of
the blockchain, each node individually chooses which
block to accept.
Absent other conditions that suggest a
more stable block, nodes usually use the first block they
see, and the problem is resolved once one chain has
more proof of work than the other.
Hard Fork
A permanent divergence in the blockchain. A
hard fork may occur when upgraded nodes
Glossary of Terms Reed Smith LLP 29
. follow newer consensus rules previously
considered invalid, and therefore newer nodes
would recognize blocks as valid that older
nodes would reject. This will cause nonupgraded nodes to not recognize and validate
blocks created by upgraded nodes that follow
newer consensus rules, creating a divergence.
Soft Fork
A temporary fork in the blockchain. A soft fork
may occur when miners using non-upgraded
nodes violate a new, stricter consensus rule of
updated nodes. This would lead to nonupgraded nodes accepting certain blocks, while
updated nodes would reject these same blocks.
Provided that a majority of nodes become
updated, a permanent fork in the blockchain
may be avoided.
Hash
A kind of algorithm that converts a string of data (of any
size) into another, usually smaller, fixed-size output in a
reasonable amount of time.
Generally, hashes are “oneway,” which means that if you have the hash, you don’t
know the original value. Hashes are used in cryptography
to compare and verify data without having to see the
original.
Hot Storage
Refers to keeping a reserve of bitcoins on a web-based
storage device or wallet.
Merkle Tree (or Hash Tree)
A cryptography term that refers to a data structure made
up of linked nodes, called a tree. A Merkle tree is a tree
in which every non-leaf node (a node with children) is
labeled with the hash of the labels of its children nodes.
Hash trees are useful because they allow efficient and
secure verification of the contents of large data
structures.
Hash trees are a generalization of hash lists
and hash chains.
Mining / Miner
Mining is the process of making computer hardware do
mathematical calculations to solve new blocks to add to
the blockchain. In the case of Bitcoin, miners are
rewarded with newly minted bitcoins. But in other
applications of blockchain, miners may be rewarded in a
different way, or not at all.
Mining Pool
30 Reed Smith LLP Glossary of Terms
Groups of people who mine together as a single unit in
order to successfully mine faster by pooling computing
resources.
Mt.
Gox
Mt. Gox was a bitcoin exchange based in Tokyo,
launched in July 2010, which by 2013 was handling 70
percent of all bitcoin transactions. In February 2014, the
company suspended trading, subsequently closed its
website and exchange service, and later filed for a form
of bankruptcy protection from creditors.
In April 2014,
the company began liquidation proceedings and
announced that approximately 850,000 bitcoins (valued
at more than $450 million at the time) belonging to its
customers and the company were missing and likely
stolen. Although 200,000 bitcoins have since been
“found,”, the reason(s) for the disappearance—theft,
fraud, mismanagement, or a combination of these—have
remained unclear.
Multi-signature Address
A multi-signature address is associated with more than
one private key.
Node
A node is a point of intersection/connection within a
network. Any computer that connects to the Bitcoin
network is called a node.
Nodes share a copy of the
blockchain and relay transactions to other nodes.
Nonce
The name for the string of digits that is added to a new
block by miners when attempting to add this new block
to the blockchain. The goal is to find the nonce that,
when linked with the previous hash and the list of
transactions comprising the new block, will produce a
hash output falling below a certain target value. Once
the correct nonce is found, the new block is added to the
Blockchain.
Because it is impossible to predict what
nonce will result in the correct target value, such a
calculation involves computing and re-computing a hash
output for numerous nonce values by “brute force.”
Presentation of the new block with the correct nonce
value constitutes proof of work.
Peer-to-Peer
Describes a type of network where each participant is
considered equal. Peer-to-peer networks share
information without a central server, controller, or
authority. Participants are often connected to a few
neighbors that will pass information to the rest of the
network, and vice versa.
.
Proof of Stake
Silk Road
Proof of stake is a method by which a cryptocurrency
blockchain network aims to achieve distributed
consensus. While the proof-of-work method asks users
to repeatedly run hashing algorithms to validate
electronic transactions, proof of stake asks users to
prove ownership of a certain amount of currency (their
"stake" in the currency). Peercoin was the first
cryptocurrency to launch using proof of stake.
Silk Road was an online black market and the first
modern darknet (a network overlay that is only
accessible by using non-standard communications
protocols and ports) market, best known as a platform
for selling illegal drugs. All products sold on the site
could be purchased anonymously with bitcoin.
Proof of Work
Data that is difficult to produce, but easy to verify.
Blockchain uses proof of work to ensure new blocks of
records added to the ledger are legitimate, because the
miner invested work in producing the new block.
Contracts allowing for contract performance to be
verified and technically enforced, without requiring a
judicial system or other centralized third party.
While
implementation of these new solutions are still fairly
theoretical, a number of companies are actively building
software solutions for smart contracts.
Private Key
Sybil Attack
The unpublished key in a public key cryptographic
system, which uses a two-part key: one private and one
public. The private key is kept secret and never
transmitted over a network. Contrast with "public key,"
which can be published on a website or sent in an
ordinary email message.
An attack to the Bitcoin network where an attacker
attempts to fill the network with nodes disguised to
appear as unique network participants, but which in
reality are nodes controlled by the attacker.
Public Key
“Virtual currency” is defined by the European Central
Bank as "a type of unregulated, digital money, which is
issued and usually controlled by its developers, and used
and accepted among the members of a specific virtual
community," and by the European Banking Authority as
"a digital representation of value that is neither issued by
a central bank or a public authority, nor necessarily
attached to a fiat currency, but is accepted by natural or
legal persons as a means of payment and can be
transferred, stored or traded electronically." The
Financial Crimes Enforcement Network (“FinCEN”), a
bureau of the U.S.
Treasury Department, has also
defined virtual currency in its guidance published in 2013.
An encryption key that can be made public or sent by
ordinary means, such as by an email message. See also
private key and public key cryptography.
Public Key Cryptography
A cryptographic system in which a two-part key is used:
one public key and one private key.
Satoshi
The smallest usable denominations of bitcoin value. One
bitcoin equals 100,000,000 satoshis.
Satoshi Nakamoto
The pseudonym of a person or group of people who
created the Bitcoin protocol and reference software,
Bitcoin Core (formerly known as Bitcoin-Qt).
Smart Contract
Virtual Currency
Wallet
The digital equivalent of a physical wallet containing
private key(s).
Each wallet can show the total balance of
all bitcoins it controls and lets users pay a specific
amount to a specific person

The terms “cryptocurrency,” “virtual currency,” and “digital currency”
are sometimes incorrectly used interchangeably. “Digital currency” is
the broadest term, and means an Internet-based medium of
exchange with characteristics similar to physical currencies. “Virtual
currency” is a subset of digital currency, and is defined by the
European Banking Authority as “a digital representation of value that
is neither issued by a central bank or a public authority, nor
necessarily attached to a fiat currency, but is accepted by natural or
legal persons as a means of payment and can be transferred, stored
or traded electronically.” Finally, “cryptocurrency” is a subset of
“virtual currency in which encryption techniques are used to regulate
the generation of units of currency and verify the transfer of funds.

“Bitcoin” with a capital B refers to the protocol or software, whereas
“bitcoin” (lower case b) refers to the unit of currency.
