Tellor (TRB) is the token of this decentralized and secure oracle that aims to automate the transfer of off-chain data to smart contracts where miners compete through Proof of Work to send the official value of finance data decentralized requested. Tellor focuses on decentralization and security. Tellor was born out of necessity. Its creators had previously created Daxia, which required an oracle. TRB tokens will be used to reward miners, deposit miners' participation and resolve system disputes.
Generally, it is an off-chain data solution when a smart contract is issued. It acts like a bank and all the data is collected within this decentralized mining ecosystem.
