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.
Decentr is allows users to generate, reuse and exchange high quality data online via a secure browser/browser extension and suite of dFintech tools. Decentr’s “data-as-value” paradigm means users see a correlated decrease in the cost of products and services bought online, via Decentr and our “dPay” system, while at the same providing superior APR’s on consumer crypto loans made via users dWallet and Decentr’s consumer crypto dLoan features. This (necessary) extension of DeFi 1.0, delivers user-centric financial services to anyone, when they want it and how they want it, regardless of their net worth.
