Tellor functions as a decentralized oracle protocol, playing a pivotal role in blockchain infrastructure. Oracles serve as integral components by providing updated off-chain data, which is then accessible for on-chain smart contracts. Tellor's oracle protocol facilitates the provisioning of data, allowing for requests, validation, and on-chain inclusion in a permissionless manner. Data reporters engage in competition for incentives in TRB tokens, contributing valuable information to various DeFi applications, thus enriching the on-chain ecosystem.
