NEST Protocol is a decentralized price oracle network built on the Ethereum blockchain. NEST defines and implements a novel solution for generating on-chain prices on the blockchain. It leverages market game theory, using a two-way bidding mechanism by miners to synchronously generate on-chain prices from off-chain markets. Furthermore, NESTs price mining mechanism incentivizes miners to participate, forming a logically closed-loop distributed bidding system. This seamlessly synchronizes off-chain prices onto the blockchain, creating the NEST price oracle.
