About Chainlink
Chainlink is an oracle platform bringing the capital markets onchain and powering DeFi. The Chainlink stack provides the data, interoperability, compliance, and privacy standards needed to power blockchain use cases for institutional tokenized assets, lending, payments, stablecoins, and more.
Background
The Chainlink protocol was created in September 2017 by Chainlink Labs (formerly known as SmartContract), which itself was founded in 2014 by Sergey Nazarov and Steve Ellis. Chainlink was created to address the “oracle problem,” which refers to introducing offchain data to the blockchain in a secure way without relying on a centralized entity.
Chainlink went live on Ethereum in May 2019. At launch, it only supported a singular ETH/USD price feed on Ethereum. In the subsequent months and years, coverage expanded to additional price feeds across several blockchains. In 2020, new product offerings, such as VRFs and Proof of Reserves, were introduced.
Notable milestones in the project’s development include:
As of May 2024, Chainlink has deployed beta mainnet versions of the “Functions” product on Arbitrum, Avalanche, Polygon, Ethereum, and Base. Additionally, Chainlink continues to release incremental upgrades across all products. The most recent release was Chainlink VRF 2.5, made available on April 29, 2024.
Furthermore, Chainlink has introduced two proposed solutions that are still under development: (i) Chainlink DECO, a privacy-enhancing protocol acquired from Cornell University in August 2020, and (ii) Fair Sequencing Services (FSS). DECO will employ zero-knowledge proofs in enabling data provenance for a specific data source or arbitrary statements on the computed data. On the other hand, FSS is a transaction ordering solution designed to mitigate harmful forms of maximal extractable value (MEV), enabling fairer decentralized systems. Based on a commercially reasonable search, the project team has yet to publish a definite release date for either of the solutions.
In August 2025 the Chainlink Reserve was introduced - a smart contract that acts as an extension of Payment Abstraction to convert offchain and onchain revenue into LINK.
At the same time, Bitwise filed an S‑1 statement with the U.S. SEC for the Bitwise Chainlink ETF, followed by Grayscale and it's GLNK ETF.
In October 2025, Chainlink introduced DataLink - a data publishing service designed to enable institutions to make market data available on blockchains.
