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.
'Tael is a digital token for safe consumer products. Thanks to its ability to be seamlessly integrated by third parties, it allows for a wide token use-case through interchangeability of the loyalty tokens on the blockchain. Tael’s first use-case is seen in Techrock’s safe consumer products ecosystem. Techrock applies banking-level, tamper-proof NFC smart-labels to consumer goods, pairing them with their digital representations on the blockchain. Consumers ‘touch’ the label with their smartphones to verify a product’s authenticity, discover the product’s journey along the supply chain, and be rewarded for their purchase. Techrock protects products where authenticity matters, such as infant formula, cosmetics, alcohol, and supplements. Tael tokens are used in the loyalty point ecosystem to reward consumers and encourage behavior in the Techrock channel while generating unique data for all companies in the value chain. Tael’s vision is to bring blockchain based payments into the mainstream, across Asia and beyond.'
