In 2021, the Chainlink ecosystem experienced significant growth, enhancing the capabilities of hybrid smart contracts within the blockchain economy. The network's total value secured (TVS) surpassed $750 billion, marking a substantial increase from the previous year, driven by the security and reliability of Chainlink's oracle networks which now underpin over 700 decentralized oracle networks across various blockchains. Chainlink's integration with over 1,000 projects, including innovative DeFi applications, NFTs, and blockchain gaming, underscores its pivotal role in securing significant on-chain value and providing critical infrastructure. Additionally, the network expanded its services with Chainlink Automation and Off-Chain Reporting (OCR), supporting multi-chain ecosystems through integration with prominent blockchains like Ethereum, Avalanche, and Polygon. The ecosystem's growth is further bolstered by partnerships with major companies such as the Associated Press and AccuWeather, which use Chainlink nodes to deliver verified data to blockchain applications. Chainlink's initiatives, including hackathons and community-driven developments, continue to foster innovation and collaboration, positioning it as a crucial infrastructure provider for the evolving decentralized economy.
