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.
Piction Network is creating a new peer to peer digital contents ecosystem. We are disrupting the centralized models of content distribution dominated by extractive intermediaries. We intend to build an ecosystem where all participants will co-exist for the healthy growth of the digital content market. Equality of opportunity should be guaranteed for many creators through low entry barriers. The final consumer should not go beyond simple purchasing but expand opportunities for the rights and participation as consumers in the content market. In addition, by creating an open market and eliminating unnecessary intermediary operators, content distributors are expected to benefit from the sharing of reasonable revenues.
