Blockchains are growing in influence for organizing digital files and business transactions. A blockchain refers to a shared, secure database of records linked in blocks. Each record contains a digital signature and cannot be altered. Blockchains provide transparency without central control, allowing transfer of anything valuable. While offering anonymity and verification, blockchains also present risks like hacking and use for illegal activities.

2. FIRST INTRODUCED BY BITCOIN,
BLOCKCHAINS ARE NOW BEING
CALLED THE MOST INFLUENTIAL
TECHNOLOGY FOR THE FUTURE OF
BUSINESS.

3. A blockchain refers to an expansive list of
records known as blocks that are linked
together and shareable.
Records include all versions and copies,
and are secured in a database.
Blockchains can be used to organize and
easily manage digital files, which can
streamline the workday.
WHAT IS A
BLOCKCHAIN?

4. The first blockchain was created by the
same person or group of people who
invented bitcoin, under the pseudonym
Satoshi Nakamoto in 2008.
The blockchain was first used in 2010
with the first bitcoin purchase.
Since then, the bitcoin blockchain has
operated flawlessly, with its only
disruptions being caused by human
errors.
THE HISTORY OF
THE BLOCKCHAIN

5. Blockchains store files in a readable
chain.
Transactions on the blockchain are
signed digitally, using something called
public key cryptography.
Public key crpytography uses a public
and private key together to make it
harder to hack.
HOW DO THEY
WORK?

7. THE PROS AND CONS OF BLOCKCHAINS
Blockchains have proven more useful than other data storage systems like the cloud because
they are transparent, incorruptible and cannot be controlled by any single entity.
According to Don and Alex Tapscott, authors of Blockchain Revolution, "The blockchain is an
incorruptible digital ledger of economic transactions that can be programmed to record not
just financial transactions but virtually everything of value."
There are several other pros and cons to consider as well:
Anything of value can be transferred and saved
safely and confidentially, without unlawful
alteration
Transactions are verifiable by a vast, peer-to-peer
global network
Transactions are irreversible
PROS CONS
The anonymity can be used to hide illegal activies
Hacks and manipulations can still occur
Transactions are irreversible
