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.
It is a blockchain-based ecosystem that connects all services, like the car dealer shops, mechanic shops and car rental companies, that touch your car to collect its lifetime data. Participants from automobile-related companies, services or trade industry will be connected and they will insert core data related to driving, traffic accidents, repairs and other car-related transactions into the blockchain. Participants who provide data related to automobile will receive MVL Point (MVP), a reward system used to encourage contribution to the ecosystem.
