Decentralised oracle network whose node operators are paid in LINK for delivering offchain data and cross-chain messages to smart contracts, and whose institutional stack is used by Swift, Euroclear, UBS and Fidelity International.
Decentralised oracle network created in 2017 by Sergey Nazarov and Steve Ellis, whose white paper with Cornell's Ari Juels was published on 4 September 2017; node operators are paid in LINK for delivering offchain data and cross-chain messages to smart contracts and post LINK as collateral against misreporting. The network reports $32.8tn of cumulative transaction value enabled as of 14 July 2026, and its institutional stack (the Cross-Chain Interoperability Protocol, the Chainlink Runtime Environment, NAVLink for fund net asset values, Proof of Reserve and the Automated Compliance Engine) is used by Swift, Euroclear, DTCC's Collateral AppChain, UBS and Fidelity International. Because tokenized funds and collateral platforms take valuation, reserve attestation and compliance checks from the same oracle layer, its failure modes are shared across otherwise unconnected venues; the Chainlink Reserve, announced on 7 August 2025, converts offchain and onchain service revenue into LINK held in an Ethereum contract behind a multi-day timelock.
