A brief history of blockchain:
1991
A cryptographically secured chain of blocks is described for the first time by Stuart Haber and W Scott Stornetta

1998
Computer scientist Nick Szabo works on ‘bit gold’, a decentralised digital currency

2000
Stefan Konst publishes his theory of cryptographic secured chains, plus ideas for implementation

2008
Developer(s) working under the pseudonym Satoshi Nakamoto release a white paper establishing the model for a blockchain

2009
Nakamoto implements the first blockchain as the public ledger for transactions made using bitcoin

2014
Blockchain technology is separated from the currency and its potential for other financial, interorganisational transactions is explored. Blockchain 2.0 is born, referring to applications beyond currency

The Ethereum blockchain system introduces computer programs into the blocks, representing financial instruments such as bonds. These become known as smart contracts.

The second generation
Other blockchains include those that run the several hundred “altcoins” – other similar currency projects with different rules – as well as truly different applications, such as:

Ethereum: the second largest blockchain implementation after bitcoin. Ethereum distributes a currency called ether, but also allows for the storage and operation of computer code, allowing for smart contracts.
Ripple: a real-time gross settlement system, currency exchange and remittance network, based on a public ledger.
