not having to entrust your personal
financial information to centralized
vendor databases. It might also possibly
entail a lower transaction fee (Bitcoin
transaction fees are much lower than
merchant credit card processing fees).
Merchant Acceptance of
Bitcoin
At the time of writing, the main Bitcoin
merchant processing solutions for
vendors to accept Bitcoin are BitPay and
Coinbase in the United States, and
Coinify in Europe.16 However, it is
difficult for vendors, like the local café,
to run two separate payment systems
(traditional and Bitcoin), so a more
expedient future solution would involve
integrating Bitcoin payment into existing
vendor payment networks. Mobile
payment functionality is also needed for
quick point-of-sale Bitcoin purchases
(for example, a cup of coffee) via
mobile phone. CoinBeyond and other
companies focus on mobile Bitcoin
payments specifically, and BitPay and
CoinBase have solutions for mobile
checkout. In one notable step forward,
Intuit’s QuickBooks accounting software
for small businesses makes it possible
for vendors to accept incoming Bitcoin
payments from CoinBase and BitPay
with its PayByCoin module. 17
Summary: Blockchain 1.0 in
Practical Use
Blockchain is already cash for the
Internet, a digital payment system, and it
may become the “Internet of Money,”
connecting finances in the way that the
Internet of Things (IoT) connects
machines. Currency and payments make
up the first and most obvious
application. Alternative currencies make
sense based on an economic argument
alone: reducing worldwide credit card
merchant payment fees from as much as
3 percent to below 1 percent has
obvious benefits for the economy,
especially in the $514 billion
international remittances market, where
transaction fees can run from 7 to 30
percent.18 Furthermore, users can
receive funds immediately in digital
wallets instead of waiting days for
transfers. Bitcoin and its imitators could
pave the way for currency, trade, and
commerce as we know it to be
completely redefined. More broadly,
Bitcoin is not just a better version of
Visa—it could also allow us to do things
we have not even thought of yet.
Currency and payments is just the first
application.19 The core functionality of
blockchain currencies is that any
transaction can be sourced and
completed directly between two
individuals over the Internet. With
altcoins, you can allocate and trade
resources between individuals in a
completely decentralized, distributed,
and global way. With that ability, a
cryptocurrency can be a programmable
open network for the decentralized
trading of all resources, well beyond
currency and payments. Thus,
Blockchain 1.0 for currency and
payments is already being extended into
Blockchain 2.0 to take advantage of the
more robust functionality of Bitcoin as
programmable money.
Relation to Fiat Currency
Considering Bitcoin as the paradigm and
most widely adopted case, the price of
Bitcoin is $399.40 as of November 12,
2014. The price has ranged considerably
(as you can see in Figure 1-2), from $12
at the beginning of 2013 to a high of
$1,242 per coin on November 29, 2013
(trading higher than gold—$1,240 per
ounce—that day). 20 That peak was the
culmination of a few factors: the Cyprus
banking crisis (March 2013) drove a
great deal of demand, for example. The
price was also driven up by heavy
trading in China until December 5, 2013,
when the Chinese government banned
institutions (but not individuals) from
handling Bitcoin, after which the price
fell. 21 In 2014, the price has declined
gradually from $800 to its present value
of approximately $350 in December
2014. An oft-reported though disputed
metric is that 70 percent of Bitcoin
trades are made up of Chinese Yuan.22 It
is difficult to evaluate how much of that
figure indicates meaningful economic
activity because the Chinese exchanges
do not charge trade fees, and therefore
people can trade any amount of currency
back and forth for free, creating fake
volume. Further, much of the Yuan-
denominated trade must be speculation
(as is true for overall Bitcoin trade), as
there are few physical-world vendors
accepting Bitcoin and few consumers
using the currency for the widespread
consumption of goods and services.
Some argue that volatility and price
shifts are a barrier to the widespread
adoption of cryptocurrency, and some
volatility-smoothing businesses have
launched to address this: Bitreserve,
which locks Bitcoin deposits at fixed
exchange rates;23 Realcoin’s
cryptocurrency, which is pegged to the
US dollar (USD);24 and Coinapult’s
LOCKS, which allow purchasers to peg
Bitcoin to the price of gold, silver, the
US dollar, the British pound, or the
Euro. 25 One of the first USD-pegged
Bitcoin cryptocurrencies was Ripple’s
XRP/USD BitStamp, and there is also
