Chainlink is an oracle platform that supports multiple open standards for designing and operating oracle services. Built upon these standards exists an ever-expanding collection of modular, purpose-built oracle services, which can be easily created and seamlessly composed using the Chainlink Runtime Environment (CRE). CRE is a developer platform and decentralized execution environment for running, managing, and composing oracle services into scalable end-to-end solutions.

Chainlink is an all-in-one platform that fulfills the requirements of institutional blockchain use cases. The Chainlink platform enables developers and institutions to access all the critical data, interoperability, compute, compliance, privacy, and legacy-system connectivity required for advanced blockchain applications that link the onchain and offchain worlds. Chainlink solves four fundamental problems for institutions interacting with tokenized assets. (1) The data problem. Tokenized assets need real-world information to be usable in transactions, such as market pricing, reference data, and proof of reserves data. Chainlink’s decentralized oracle networks are used to aggregate and verify real-world information before delivering it to blockchains and smart contracts. (2) The liquidity problem. Financial institutions need tokenized assets that can be securely accessed and moved across blockchain networks in order to maximize liquidity. Chainlink CCIP is a cross-chain interoperability solution that enables secure connections between public and private blockchains, opening access to global markets for tokenized assets. (3) The synchronization problem. Tokenized assets must remain synchronized with legacy systems once issued across multiple chains. The Chainlink platform offers reliable offchain data, system connectivity, and secure cross-chain interoperability, enabling a Unified Golden Record that stays with assets anywhere. (4) The compliance problem. Regulated institutions require compliance enforcement capabilities such as identity verification (KYC), risk screening (AML), exploit protection, and asset-specific restrictions. The Chainlink Automated Compliance Engine extends existing financial infrastructure for identity and compliance data to blockchains and tokenized assets.

Traditional financial institutions and infrastructures, such as Swift, DTCC, Euroclear, J.P. Morgan, Mastercard, Central Bank of Brazil, UBS, SBI, Fidelity International, ANZ, and many others are adopting Chainlink as infrastructure as they move toward tokenizing trillions onchain. Demand for Chainlink has already generated hundreds of millions of dollars in revenue across a variety of traditional and decentralized use cases.

Chainlink was co-founded by Sergey Nazarov and Steve Ellis in 2017. Nazarov had previously developed blockchain-related projects, including SmartContract, which aimed to link smart contracts with external data sources. Ellis, a software engineer, co-founded Secure Asset Exchange, a project focused on decentralized asset transfers. Their shared vision for enabling trust-minimized, data-driven smart contracts led to the creation of Chainlink, which has since expanded its partnerships and adoption across blockchain ecosystems.
