DAGA (Digital Asset Growth Agent) aims to establish a distributed future credit system, which is the foundation of financial and commercial operations. The DAGA protocol will combine and re-innovate based on the advantages of some blockchain technologies, and propose solutions for commercial lending, fundraising, investment, fund management, and fund exit. The DAGA protocol completes the technical connection and value exchange of different blockchains in a distributed manner. In this connection process, it is necessary to establish a universal cross-chain asset exchange protocol, cross-chain transactions, and a distributed accounting system for intra-chain transactions. The DAGA protocol needs to be able to support public chains, private chains, and alliance chains. Assets on the chain in a broad sense can be used as the basis for credit establishment. The DAGA protocol can also reward Tokens to addresses on the chain according to the execution results of asset transactions. In the end, the number of Tokens held by DAGA represents the value of credit in the value-added business of cross-chain assets. Evaluation Standards.
