Added
Security
IBM delivers additional protection for blockchain
By Paul DiMarzio k Illustration by Greg Mably

n November 2008, someone
writing under the pseudonym
Satoshi Nakamoto published
the paper "Bitcoin: A Peer-to-Peer
Electronic Cash System" (bitcoin.
org/en/bitcoin-paper). A few
months later, the first Bitcoin
was successfully mined, setting a
revolution in motion.
More recently, an idea took
shape to deploy the technology
underlying Bitcoin-loosely
referred to as blockchain-to use
cases other than the creation of
a cryptocurrency. This is because
blockchain is a mechanism for
creating distributed, shared
ledgers that are transparent,
secure and immutable.
Because so many of the
world's business processes
rely on that age-old accounting
mechanism, the ledger, a
distributed ledger technology
that could guarantee trust and
remove friction among trading

partners has the potential to
radically change the way business
transactions are processed in
a number of industries. Read
about how blockchain can and is
transforming industries in "The
Business of Blockchain," page 18.
A key component to succeeding
with blockchain lies in an oftenmisunderstood detail: security.

Technology Adjustment
Bitcoin was created and designed
as an alternative to government
centralization and management of
fiat currency. As such, it's a fully
distributed architecture with no
central oversight or single point
of control. The development of
Bitcoin seems to have been as
much a philosophical statement
as a technological one.
From a security perspective,
Nakamoto's decentralized design
can't be compromised unless an
entity were to gain control of half
