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.
ADN Mainnet is a blockchain-based technology designed to secure ICO investments. Going beyond decentralization, we are pioneers of a built-in investor-oriented mechanism to ensure security and transparency to our investors. ADN aims to transcend into the future of blockchain and ICO with continuous development and innovation. Aiming to provide a tangible solution to existing problems within the industry, we developed a blockchain with high-throughput, high scalability, and high availability for Decentralized Applications (DApps) in the ADN ecosystem. Combining the benefits initially proposed by its cryptocurrency predecessors such as Bitcoin, Ethereum, EOS and TRON, the ADN protocol becomes a high-performance blockchain platform. Integrating the Delegated Proof-of-Stake (dPoS) consensus and ADN Virtual Machine (AVM), it primarily focuses on smart contracts, consensus, and ICO wallet.
