The smart contract ecosystem has experienced significant growth, increasing the need for secure oracles to supply high-quality data to DeFi protocols and decentralized applications. Chainlink, a leading decentralized oracle solution, is addressing this demand by expanding the data types available to smart contracts across major blockchains, including market, gaming, insurance, and proof of reserve data. Sergey Nazarov, Chainlink's Co-founder, highlighted in his ETHOnline DeFi Day 2020 presentation that Chainlink's network is enabling a variety of new smart contract use cases by providing access to additional off-chain resources. This expansion includes on-chain gaming data, insurance data, and proof of reserve data, facilitating the creation of new DeFi markets and collateral options. Chainlink's integration with services like Everipedia and The Associated Press further demonstrates how additional datasets and computations are being utilized to develop innovative protocols and services within the smart contract ecosystem.
