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.
The VideoCoin Network is a decentralized video infrastructure platform redefining the process for creating, storing, and distributing digital video content. The project is led by the VideoCoin Development Association Ltd. (Cayman Islands). Powered by a large-scale, distributed video infrastructure, the VideoCoin Network will usher in 'the new cloud,' by marshaling underutilized computing resources from around the world to revolutionize video services with blockchain technology. The VideoCoin Network ecosystem will lower costs by deploying unused compute resources and peer-to-peer video distribution, enabling a new generation of applications via open APIs and open source-based development, with increased privacy using decentralized, end-to-end encryption. The VideoCoin Network is the first blockchain project to integrate a third party fiat payment processor, underpinned by a consortium of banks. The model is optimized to enhance the utility of the VID as a reputational staking token that powers the network and ensures that the most qualified network operators are serving customer needs.
