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.
Egretia is cooperating with Egret Technology, a globally well-known HTML5 technology service provider, set up Egretia Blockchain Lab, combining blockchain with HTML5 technology to create the world’s first HTML5 blockchain engine and platform, aiming for applying blockchain to vertical industries. Bringing Egret Technology's existing 200,000 developers and 1 billion mobile terminal devices into the blockchain world, this project has practical and far-reaching significance. As a cross-platform solution, HTML5 technology has been globally recognized. It covers the Internet, mobile games, video, advertising and other industries, with the global market size of hundreds of billions dollars. After blockchain game CryptoKitties became popular, Ethereum's smart contract applications added a new member - HTML5 games.
