Cryptopedia - Chainlink

#### What Is Chainlink (LINK)? Founded in 2017, Chainlink is the industry-standard oracle platform bringing the capital markets onchain and powering the majority of decentralized finance (DeFi). Chainlink stands to benefit the most from emerging blockchain-industry trends, such as stablecoin adoption, real-world asset tokenization, and institutional adoption of blockchain technology. Chainlink is powered by the LINK token, which is used to pay for platform services and secure the network’s proper functioning. Chainlink leverages a novel fee model where offchain and onchain revenue from enterprise adoption is converted to LINK tokens and stored in a strategic Chainlink Reserve. Chainlink is at the forefront of financial innovation and the global tokenization trend. 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 fundamental 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. Who Are the Founders of Chainlink? [Sergey Nazarov](https://www.linkedin.com/in/sergeydnazarov/) is a co-founder and CEO at Chainlink Labs. He graduated with a degree in business administration from New York University, with a focus on philosophy and administration. His professional career began as a teaching fellow at NYU Stern School of Business. In 2009, Nazarov co-founded ExistLocal, a peer-to-peer marketplace for authentic local experiences. Nazarov has worked in the blockchain industry since 2010, giving him one of the longest-running tenures of any technologist in the industry, which began only a year earlier in 2009 with Bitcoin’s creation. Sergey initially built some of the first smart contracts before blockchains like Ethereum were even a concept and went on to invent Decentralized Oracle Networks (DONs) in the Chainlink whitepaper. In 2014, he also co-founded CryptaMail, a completely decentralized, blockchain-based email service. In 2014, Nazarov teamed up with [Steve Ellis](https://www.linkedin.com/in/steveellis0606/) and launched SmartContract, a platform that brings smart contracts to life by connecting them to external data and widely accepted bank payments. SmartContract was one of the entrepreneurial ventures that led Sergey Nazarov to the founding of Chainlink. What Makes Chainlink Unique? Chainlink is the only all-in-one platform that fulfills the requirements of any institutional blockchain use case. 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: 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 is the market leader in bringing real-world data onchain securely and accurately. 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 the only cross-chain interoperability standard that securely connects any public or private blockchain, opening up global markets for tokenized assets. The synchronization problem. Tokenized assets must remain synchronized with legacy systems once issued across multiple chains. Chainlink is the only platform that offers reliable offchain data, system connectivity, and secure cross-chain interoperability, enabling a Unified Golden Record that stays with assets anywhere. 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. Since launch, the Chainlink standard has securely enabled tens of trillions in transaction value across dozens of blockchains and published tens of billions of verified messages onchain. Chainlink actively secures the large majority of DeFi protocols across different blockchains, with near total dominance on Ethereum. As a chain-agnostic platform with thousands of users across the world’s largest financial institutions and DeFi protocols, Chainlink accelerates the adoption of blockchain ecosystems and is used by tens of thousands of developers, including protocols such as Aave, GMX, Lido, and many more. Chainlink and Google, Introduction of Staking in 2022, and Introduction of the Chainlink Reserve in 2025. Chainlink has grown from aggregating and providing cryptocurrency price data to DeFi protocols like Aave, to a lot more. The ecosystem currently access over 1B data points, securing over $95B in value across 1,000 project integrations with 700 oracle networks. Mainstream organizations like Swift, J.P. Morgan, Mastercard, and Euroclear have partnered with Chainlink. Another win Chainlink has secured is onboarding Eric Schmidt, ex-Google chairman and CEO, as a technical advisor to the oracle platform. According to Schmidt, "Chainlink is a secret ingredient to unlocking the potential of smart contract platforms and revolutionizing business and society," and he is interested in helping Chainlink build a world powered by truth. Schmidt joins other notable Chainlink advisors, including former LinkedIn CEO Jeff Weiner and DocuSign co-founder Tom Gonser. In 2025, Chainlink launched the Chainlink Reserve is a strategic onchain reserve of LINK designed to support the long-term growth and sustainability of the Chainlink Network by accumulating LINK tokens using offchain revenue from large enterprises that are adopting the Chainlink standard and from onchain service usage.
