NEST Protocol is a distributed oracle network and a permissionless community of token holders, data providers, and validators. As an oracle, NEST Protocol provides a solution to certificate on-chain data, e.g. quotes of digital assets. In NEST network, all data is directly generated on-chain: users (so-called Quote Miners) upload their own asset price quotes with a certain amount of collateral, and the quotes will input to NEST's price chain after a fixed verification period.
