Tellor Tributes (TRB) addresses a significant limitation of Ethereum's smart contracts, which operate independently and lack direct access to external data sources. To bridge this gap, Tellor establishes a framework that allows users to request off-chain data points, such as the ETH/USD exchange rate. In this system, miners compete to provide accurate data, which is then recorded in an on-chain database accessible to all Ethereum smart contracts.
The integrity of the data inputs is maintained by a decentralized network of staked miners, ensuring reliability and security. The primary Tellor smart contract maintains a chronological series of each requested data point, positioning itself as a key provider of valuable information for decentralized applications. As an oracle solution, Tellor employs incentive structures akin to those found in other cryptocurrency networks. The platform issues its native token, Tributes, which users can utilize to solicit specific data series from miners, fostering a competitive and efficient marketplace for off-chain information.
