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 ILCoin blockchain is a revolutionary on-chain data storage system; developed not only to provide a strong foundation for the ILCoin cryptocurrency, but also to open up a wide range of possibilities for exceptionally safe yet transparent data storage, establishment of various smart contract systems and the launch of innovative decentralized applications running on our blockchain systems. What started as an alternative to Bitcoin (BTC), today, has built its own unique blockchain network. Our blockchain network is a revolutionary Decentralized Cloud Blockchain System where on-chain data storage is secured and managed by a quantum resistant SHA-256 Command Chain Protocol (C2P). The ILCoin Blockchain System has not only effectively future-proofed itself against impending threats of quantum computing, but also is proven to be immune to malicious, third-party 51% attacks.
