On February 14th, Jupiter Lianchuang Meow published a document saying that Jupnet is a full-chain network being built to achieve the goal of'aggregating everything '. Jupiter needs infrastructure to connect billions of people and trillions of tokens, so it needs: 1. A single source of truth across the chain. 2. A full-chain ledger; 3. A fully on-chain identity system. Blockchain solves the problem of a single source of fact internally, but not across chains. Therefore, a completely new architecture is required to achieve a single source of fact across chains. Therefore, DOVE: Decentralized verification and execution oracle, by decentralizing the single fact state, will be able to host a decentralized full-chain ledger, including the implementation of dynamic finality. Finally, a fully on-chain identity system will be able to support all traditional authentication methods, including social logins and keys, as well as the ability to generate recovery keys when users need them. There are still many technical issues and important design issues to overcome. We expect to provide a technical preview and a detailed technical overview in early April.
