Ethereum

Ethereum is an open-source, globally

decentralized computing infrastructure

that executes programs called smart contracts.

It uses a blockchain to synchronize and store

the system's state changes, along with a

cryptocurrency called ether to constrain

execution resource costs.

Ethereum is a deterministic but unbounded

state machine, consisting of a globally

singleton state and a virtual machine

applying changes to that state.

Ethereum's language is Turing-complete,

meaning that Ethereum can straightforwardly

function as a general-purpose computer.
