Archived from the original on 6 May In December , Vitalik started sharing a whitepaper that outlined the idea behind Ethereum: These are the people who decide on a course of action on the platform. Most simply stated, the blockchain is a public arbitrator of transactions which cannot be altered and does not fall under the control of any one entity. The Ethereum Virtual Machine has three areas where it can store data- storage, memory and the stack, which are explained in the following paragraphs. Because of the way the Patricia tree works, if few changes are made then most parts of the tree will be exactly the same as in the last block; hence, there is no need to store data twice as nodes in the new tree will simply be able to point back to the same memory address that stores the nodes of the old tree in places where the new tree and the old tree are exactly the same.

Ethereum Virtual Machine is amazing and has incredible potential. The Ethereum blockchain or "ledger" is the decentralized, massively replicated database in which the current state of all accounts is stored. For example, in December, the biggest sales were valued between and ETH.
