Chainlink the Whitepaper for its second iteration. Chainlink 2.0 has been created to allegedly take the “next steps in the evolution of decentralized oracle networks”. With one of the most used applications in DeFi, these protocols need oracles to feed them with off-chain information. In the new iteration, Chainlink could go beyond, as the document claims: We foresee an increasingly expansive role for oracle networks, one in which they complement and enhance existing and new blockchains by providing fast, reliable, and confidentiality-preserving universal connectivity and off-chain computation for smart contracts. Chainlink 2.0 will be based on a concept called Decentralized Oracle Networks (DON). Maintained by “a committee of Chainlink nodes”, the platform will be able to support an “unlimited” number of functions.
