Ethereum was created in 2015 by Vitlaik Buterin, Gavin Wood, and Jeffrey Wilcke. With this cryptocurrency, it was possible to create DAPPS (decentralized applications) for the first time. These run on so-called smart contracts. Ethereum also became the basis for other cryptocurrencies that exist as ERC-20 tokens on the Ethereum blockchain.
The Ethereum network is currently kept active by means of the proof-of-work algorithm, which is to be replaced by a proof-of-stake algorithm in the course of the development phases.
MyEtherWallet is a free open-source project. It provides the user with an interface for the Ethereum blockchain. Through this interface to the ETH Blockchain, it is possible to gain an insight into the transactions made there.
