Blockchain is a digital ledger that can record transactions of any valuable asset in a way that is incorruptible and verifiable. It was first conceptualized in 1979 as a way to securely share data across networks, and was realized in 2008 with the creation of Bitcoin which used blockchain as its underlying infrastructure. Blockchain technology is now poised to enable the exchange of any asset of value through the emerging "Internet of Value," with applications spanning finance, cybersecurity, and the Internet of Things.

2. what?
Blockchain is an incorruptible digital ledger of
economic transactions that can be
programmed to record not just financial
transactions but virtually everything of value.

3. how?
The very primitive form of the blockchain was the hash tree, also known
as a Merkle tree. This data structure was patented by Ralph Merkle in
1979, and functioned by verifying and handling data between computer
systems. In a peer-to-peer network of computers, validating data was
important to make sure nothing was altered or changed during transfer.
It also helped to ensure that false data was not sent. In essence, it is used
to maintain and prove the integrity of data being shared.

4. bitcoin
In 2008, Satoshi Nakamato conceptualized the distributed blockchain. It
would contain a secure history of data exchanges, utilize a peer-to-peer
network to time stamp and verify each exchange, and could be managed
autonomously without a central authority. This became the backbone of
Bitcoin. And thus, the blockchain we know today was born, as well as the
world of cryptocurrencies.

5. internet-of-value
Internet of Value (IoV) will enable us to exchange any asset of value with
another person – from stocks to votes, to frequent flyer points, to
intellectual property, and more. Blockchain is the value exchange
protocol which will take over further.
