Tellor
Tellor is a permissionless oracle protocol that uses a dedicated L1 and incentivized reporters to bring data to any chain.

What is Tellor?
Tellor Layer is a stand-alone L1 where TRB-staked reporters publish data and validators aggregate it via median consensus. A light-client bridge relays attestations to Ethereum, Arbitrum and other EVM chains, giving dapps censorship-resistant price feeds, custom data queries and dispute resolution without relying on a single source.
