Tellor is a decentralized middleware protocol.
Middleware represents a crucial part of the underlying blockchain architecture that updates valuable off-chain data, making it available to smart contracts on-chain.
Tellor's middleware provides data that can be requested, verified, and placed on-chain in an open manner for the public, with competing data senders incentivized by TRB rewards. Data senders provide valuable on-chain information for a wide range of decentralized finance applications.
