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.
Bankera is an operational fork of SpectroCoin. As SpectroCoin to be competitive has developed bank-like infrastructure, but was not intended to become a proper bank, it is releasing Bankera to leverage its regulatory and IT infrastructure to develop a bank for the blockchain era. Bankera as a proper bank will offer payments, investments, and loan and deposit solutions. Later on, it is planing to develop new types of money, such as inflation linked baskets.
