DAGA (Digital Asset Growth Agent) aims to establish a distributed future credit system, which is fundamental to the operation of financial and commercial activities. The DAGA protocol will leverage and innovate upon the benefits of various blockchain technologies, proposing solutions for commercial lending, fundraising, investment, fund management, and exit strategies. Through a distributed approach, the DAGA protocol facilitates the technical connectivity and value exchange between different blockchains. This process involves establishing a universal cross-chain asset exchange protocol, cross-chain transactions, and a distributed ledger system for on-chain transactions. The DAGA protocol needs to support public chains, private chains, and consortium chains. Broadly defined, on-chain assets can serve as the foundation for credit establishment. Additionally, the DAGA protocol rewards chain addresses based on the execution results of asset transactions with Tokens. Ultimately, the quantity of DAGA Tokens held represents the standard for evaluating credit in cross-chain asset appreciation businesses.
