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.
What is HashNET? HashNET is a scalable, fast, secure, and fair decentralized- beyond blockchain project, leveraging Distributed Ledger Technology (DLT) and consensus algorithm which keeps all positive characteristics of a blockchain technology while increasing throughput to more than 200,000 transactions per second. Network is using Proof-of-Stake with masternodes, which eliminates the need for a massive energy consumption.
