Ethereum is arguably the second most popular cryptocurrency after Bitcoin. With the second largest market capitalization in the whole cryptocurrency market, it was the first cryptocurrency to feature “smart contracts”. Smart contracts are individual, decentralised and self-executing agreements which are coded into the blockchain.

Developed by Vitalik Buterin in, Ethereum went live with its beta version in 2015. It features the Ethereum virtual machine, or EVM, capable of running smart contracts as a representation of financial agreements such as swaps, options contracts and coupon paying bonds. One can use Ethereum to fulfil employment contracts, as a trusted escrow and to execute wagers and bets.
