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.
Plair aims to unify the gaming and streaming worlds onto one platform, propel the amateur eSports scene into the global spotlight, bringing opportunities to gamers of all skill, and give the GAMERS ownership and control of their own data. Additionally, they plan to launch a distributed cloud computing network in which users can rent, play, and stream video games using the combined power of the network's contributors. The PLA token is the blood of this entire ecosystem, itself built upon the ecosystem that is the VeChainThor blockchain, which gives Plair the scalability advantages it needs to succeed over competitors.
