Smart contracts on Ethereum are fully self contained and any information or access to off-chain data is restricted. Tellor solves this problem by creating a system where parties can request the value of an off-chain data point (e.g. ETH/USD) and miners compete to add this value to an on-chain data bank, accessible by all Ethereum smart contracts. Inputs to a data series are secured by a network of staked miners. The main Tellor smart contract creates a time series of each requested data series and aims to become the standard source of high value data for decentralized applications. This oracle, “Tellor”, utilizes similar incentive mechanisms to other cryptocurrency systems through the issuance of Tellor’s token, Tributes, that are used to request a particular data series from miners.

Tellor是一个去中心化的Oracle预言机网络平台，用于将高价值的链下数据融入以太坊。该系统利用有争议的矿工网络竞争解决PoW问题，在链上监测用户数据请求，链下监控和接收数据请求。每个成功的Tellor数据点都将使用代币进行开采，该公司拿出10％的开发份额以支持生态系统的发展。
