The Chainlink decentralized oracle network is one of the key pillars supporting the global DeFi ecosystem with its price feeds. Its oracles power some of the leading DeFi apps by providing them access to secure, tamperproof, reliable, and timely updates on pricing, without downtime or corruption. Chainlink’s DON is the most popularly used decentralized oracle service in the DeFi industry as of 2022, giving it an edge over its competition. In addition to Price Feeds, Chainlink also offers several other essential services for use within the DeFi market, including Proof of Reserve, Keepers, Verifiable Randomness Function (VRF) as well as Cross-chain Interoperability. It lets DeFi protocols receive off-chain, real-world data and computation. In addition, the Chainlink 2.0 brings with it higher levels of scalability and capability with its plans to support multi-chain DeFi environments as well.
