Tellor TRB to Presearch PRE Exchange

Crypto Pair Details: TRB to PRE

Tellor TRB

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.

Presearch PRE

Presearch is an open, decentralized search engine that rewards community members with Presearch Tokens for their usage, contribution to, and promotion of the platform. In a world where one company controls 77% of all searches, influencing trillions of dollars in spending, shaping perceptions and effectively acting as the primary gatekeeper to the Internet, a new, open and community-driven search engine is a necessity. Presearch has an innovative go-to-market strategy to target the most frequent searchers - web workers - and gain early adoption, on our way to releasing future versions of the open source platform that will utilize a blockchain-based index, curated by the community.
