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.
Envion has created the technology for the first truly mobile mining unit (MMU) that uses low-priced local energy to mine a broad spectrum of cryptocurrencies. By harvesting locally available clean energy right at the source, Envion can operate at a lower cost than competitors and at the same time reduce the CO2 footprint of the blockchain industry. Envion aims at decentralizing the highly-concentrated mining market and at bringing back control of the market to the users. Hence, profits generated by MMUs are 100% beneficial to token holders. Distribution of profit dividends will occur on a weekly basis: 75% of profits will be emitted, while 25% will be used to reinvest directly in MMUs, in order to guarantee exponentially growing profits to the envion community.
