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.
TEMCO is the world's first Bitcoin Smart Contract (RSK) based supply chain data platform. TEMCO connects isolated supply chain data and offers business and consumer services. On the business side, TEMCO provides a Business Intelligence Tool (BI-Tool) to help companies efficiently analyze and gain insights from data on the blockchain. On the consumer side, TEMCO is developing an application where consumers can view transparent supply chain and product data starting from the manufacturer to the final consumer. In addition, TEMCO offers a marketplace where vendors and consumers can directly transact using both fiat and TEMCO tokens.
