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.
Dimension is committed to building a next-generation enterprise-grade blockchain network service, by using C.H.A.O.S. (hybrid consensus, dynamic node, and cross-consensus engine) and DeCommerce service framework (decentralized storage system, decentralized computing framework, and decentralized data trading platform). With the adaptive functionality of the multi-sidechain model, Dimension-X, Dimension satisfies different needs from different business scenarios. It also features a cutting edge community system, which facilitates a more efficient and more friendly blockchain environment and ecosystem.
