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.
Sentivate is a revolutionary advancement, not evolutionary, in Internet architecture. Sentivate has a hybrid topology consisting of interconnected centralized & decentralized systems. The network is designed to go beyond the capabilities that any solely centralized or decentralized network could offer. Sentivate has the ability to operate in a decentralized or centralized topology, if the need ever arose, giving it a unique dynamic topology. With Sentivate's data transport protocol, UDSP, all the issues associated with TCP will be a relic of the past. Sentivate is designed to be a realistic and viable replacement for the increasingly slugish Web we have today.
