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.
Vexanium is building the next generation blockchain for mass adoption, which was born to support the use of DApps (Decentralized Applications) and retail penetration. Vexanium is a blockchain technology that can be accessed and applied to various industries. Currently vex uses delegated proof of ownership [DPOS], Vexanium now operates a smart contract platform and is a decentralized operating system aimed at decentralized applications through a decentralized autonomous enterprise model. We are confident that the technology we bring will have a tremendous impact in all industries and many business models that can be helped.
