Ethereum
Ethereum is a decentralized open-source blockchain platform with smart contract function, designed to "building unstoppable applications". It uses its dedicated cryptocurrency Ether (ETH) to provide a decentralized Ether virtual machine to handle peer-to-peer contracts between users. Ethereum was formally announced by Vitalik Buterin on January 25, 2014, and it was officially launched on July 30, 2015.

Smart Contract
Smart contract is a computer protocol that proposed in 1995 by Nick Szabo, it's designed to spread, verify or execute a contract in an information-based way. It allows users to conduct secure transactions without audited from a third-party, and those transactions are traceable and irreversible.

The purpose of smart contract s is to provide a safer method than traditional contract s and reduce transaction costs between users.
