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.
Actinium is more than a crypto currency. Actinium is a decentralized currency built on blockchain technology that aims to help bring crypto into every customer’s pocket, every store, and be extraordinarily safe and easy to use. This can be achieved because Actinium is a Lightning Network supported coin that will allow instant transactions with near-zero fees, atomic swaps, and many of the numerous other 2nd Layer solutions. Actinium is completely decentralized without premine and is not an ICO. It has proper mining support, mobile wallets, and hardware wallet integration. Actinium has all the needed features already activated to achieve Lightning Network compatibility. Actinium will not remain a blockchain-only cryptocurrency. The inevitable progress will deliver competing solutions to many problems on different layers.
