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.
Endor.coin is reinventing predictive analytics by democratizing access to Artificial Intelligence data analysis, making it accessible, trustless, censorship-resistance and useful for all. This is achieved through the Endor.coin Protocol, offering the world’s first automated, self-served, predictive platform that allows business users and unprofessional crypto-token holders alike to ask complex predictive questions and obtain high-quality results in minutes. This aims to democratize the field of Data Science, that today is reserved mostly for Fortune500 companies. Endor.coin is based on the novel science of Social Physics developed at MIT by the project’s team members Prof. Alex Pentland and Dr. Yaniv Altshuler
