Chainlink initially pioneered decentralized oracle networks for the secure and reliable transfer of external data to the blockchain. The next stage of development, outlined in the White paper Chainlink 2.0, offers a solution for multiple interoperable Decentralized Oracle Networks (DONs). Each network consists of nodes capable of transmitting data in p2p mode and performing decentralized off-chain computing using various consensus protocols. The functionality of Chainlink 2.0, according to the developers, stimulates innovation in many leading blockchains, providing developers with the key functions of the oracle.
