As one can tell, Ethereum is a cryptocurrency that is based on blockchain technology. Like Bitcoin, it is a cryptographically signed record of a transaction and store of value. Ethereum was first launched in mid-2015. This means it is still a relatively new technology but it is indeed taking the world by storm. Like Bitcoin, Ethereum is also built on a public blockchain. Think of the blockchain as a public ledger of all the transactions that are taking place. The central idea behind the Ethereum protocol is that of “smart contracts”. It is also a piece of blockchain technology that enables developers to build and deploy decentralized applications. On the Ethereum network, miners work to earn “Ether”. This is also used by application developers to pay for transaction fees on the entire network.
