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.
Enecuum is the next-generation blockchain that improves security through mathematical smart contracts, allowing instant transactions with zero commission and solving the problem of network scaling by simultaneously supporting three algorithms for mining: PoS, PoW, PoA. 'The project was created as an ideal environment for decentralized applications and business applications. The basic requirements that we set for the project are scalability, speed and security. Using revolutionary developments - mobile mining, smart contracts on Petri nets and linear logic, a hybrid consensus algorithm and project management based on the time contribution to its development and many other solutions, we have created a protocol of tomorrow. Distributed experienced team is constantly working in Hong Kong, Dusseldorf, St. Petersburg, Seoul in order to launch the network and give everyone the opportunity to feel the block of tomorrow.'
