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.
Cryptaur is a decentralized Ethereum-based ecosystem that will act as a framework for potentially unlimited number of specialized P2P services (dApps) whereby suppliers and consumers of a most diverse range of goods and services can interact directly while increasing the economic efficacy of all transactions being made within the ecosystem. The unique features of the Cryptaur ecosystem include: Universal payment and reward unit—the Cryptaur utility token (CPT). Multi-functional payment platform—Cryptaur Pay (CPP). Proprietary Social Capital Management System (SCMS). Global User Rights Protection System (URPS).
