Rust_Credit_System_v1

Decentralized Credit Creation System, Technical Implementation needed.

Elaborate on any specific component, such as the credit assessment algorithms, the governance mechanisms, or the deployment infrastructure, then provide more detailed code examples for particular aspects of the system: Provide a robust foundation for creating decentralized credit creation institutions that prioritize productive and creative investments while maintaining democratic governance and ecological integration.
