The profile

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.

Products and services

Cross-Chain Interoperability Protocol (CCIP): Message and token transport between chains, used for delivery-versus-payment settlement demonstrations with Swift and for bank stablecoin transfers.
Chainlink Runtime Environment: Workflow layer that translates existing bank messaging into onchain actions, used in DTCC's collateral eligibility, valuation and margining work.
Chainlink Reserve: Ethereum contract that accumulates LINK converted from service revenue through Payment Abstraction, withdrawable only after a multi-day timelock.

Kalshi asks the CFTC to approve equity index and copper perpetuals

Kalshi submitted perpetual futures on the MerQube US Large Cap Index and on copper for Commission review and approval under regulation 40.3(a) on 18 August 2026, rather than self-certifying them. The copper contract references the Pyth Network XCU/USD feed, and the filing tells the regulator that the network's staking and slashing safeguard is not currently operative.
