Chainlink, celebrating its third anniversary since launching on the Ethereum mainnet on May 30, has evolved to become a vital oracle infrastructure within the Web3 ecosystem, thanks to contributions from developers, researchers, and community members globally. Initially starting with three oracle nodes for a single ETH/USD price feed, Chainlink has expanded to nearly a thousand decentralized oracle networks across 12 blockchains and layer 2 networks, supporting smart contracts worth billions of dollars. It is widely recognized as a critical component in the DeFi sector, extending its services beyond price feeds to include trust-minimized services like verifiable random numbers and transaction automation, which power innovations in dynamic NFTs, play-to-earn games, and other applications. Chainlink's milestones include providing multi-chain support, enabling secure off-chain computations, and integrating with over 1320 projects, including major enterprises like Amazon Web Services and Google Cloud. Its community-driven approach, comprising developers, node operators, and integration feedback from dApp teams, has been instrumental in establishing industry standards for oracle services and fostering blockchain innovation.
