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.
Leveraging on blockchain technology, we develop a decentralized, low-cost, and private AI computing platform and also provide perfect peripheral products. The DeepBrain Chain token is traded via smart contract based on NEO, and our token is called DeepBrain Coin (DBC), and the mining node is encouraged according to the incentive system designed by the smart contract. The DeepBrain Chain is a decentralized neural network. The calculating demands of enterprises will be distributed to countless mining nodes all over the world. It will get DBC as a return when the nodes deployed computational mirror image successfully and the GAS fee each enterprise need to pay is far less than the intrinsic fee. The DeepBrain Chain is also a secure data trading platform. Both of the trading parties don’t need to worry about data leakage or reselling. Blockchain technology is used to realize the separation of data ownership and usage rights drastically. Thus, the value of data will be promoted greatly. “the Uber in AI computing”
