'Remme is an ecosystem of Identity and Access Management products with a digital key at its heart. Founded in 2015, Remme is building the decentralized Public Key Infrastructure protocol and PKI-enabled apps to address the challenges of Web 3.0. Remme Protocol aims to become the next-generation blockchain-based PKI alternative. It is open-source and customizable to suit business needs. Remme Protocol provides a basis for establishing self-sovereign and authority-issued identities, with a host of use cases. Remme Auth is a 2-click authentication solution that allows users to securely access a website without passwords. Instead, the solution uses Web Cryptography API and blockchain technology. With the Protocol being built on EOSIO codebase, REMChain is an independent blockchain fueled by the REM token. REM is an ERC-20 token on Ethereum with the permanent possibility to swap it to REMChain native tokens in both directions.'
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.
