Tellor is a decentralised oracle network that provides secure and reliable real-time data for decentralised finance (DeFi) applications on the blockchain. It ensures that smart contracts access high-quality data, which is crucial for their execution. Tellor leverages a network of proof-of-work miners who compete to submit the value of off-chain data, securing the network and reducing the risk of manipulation. The TRB token, integral to the system, incentivises miners and is used for governance and payments within the Tellor ecosystem.
