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.
Jelurida is developing its next generation scalable blockchain platform – Ardor, currently running on a testnet. The unique design of this platform allows the simultaneous existence of multiple blockchains, known as child chains, with many features and with their security guaranteed on a global level by the parent Ardor chain. The first child chain of Ardor will be the Ignis child chain which will use IGNIS tokens for its operation. All existing and well tested Nxt blockchain features will be available on the Ignis child chain, with multiple Ardor platform specific enhancements being added.
