Enigma (ENG) is a crypto platform that’s trying to solve the problem of privacy on the blockchain by giving access to data storage and privacy while remaining scalable. Enigma aims to extend Ethereum Smart Contracts by introducing secret contracts.
Secret contracts would operate off-chain, meaning the execution of the contract doesn’t occur on the Ethereum blockchain, but rather sorts any related data into pieces, encrypts those pieces, and distributes them redundantly among Enigma nodes.
