# Network - Distributed P2P Database System
|
||||
|
||||
This is a distributed peer-to-peer network project built with Go and LibP2P. The system provides decentralized database capabilities with consensus and replication.
|
||||
|
||||
## Key Components
|
||||
|
||||
- **LibP2P Network Layer**: Core networking built on LibP2P for P2P communication
|
||||
- **Distributed Database**: RQLite-based distributed SQLite with Raft consensus
|
||||
- **Client Library**: Go API for applications to interact with the network
|
||||
- **Application Isolation**: Each app gets isolated namespaces for data and messaging
|
||||
|
||||
## Development Guidelines
|
||||
|
||||
1. **Architecture Patterns**: Follow the client-server pattern where applications use the client library to interact with the distributed network
|
||||
2. **Namespacing**: All data (database, storage, pub/sub) is namespaced per application to ensure isolation
|
||||
3. **Error Handling**: Always check for connection status before performing operations
|
||||
4. **Async Operations**: Use context.Context for cancellation and timeouts
|
||||
5. **Logging**: Use structured logging with appropriate log levels
|
||||
|
||||
## Code Style
|
||||
|
||||
- Use standard Go conventions and naming
|
||||
- Implement interfaces for testability
|
||||
- Include comprehensive error messages
|
||||
- Add context parameters to all network operations
|
||||
- Use dependency injection for components
|
||||
|
||||
## Testing Strategy
|
||||
|
||||
- Unit tests for individual components
|
||||
- Integration tests for client library
|
||||
- E2E tests for full network scenarios
|
||||
- Mock external dependencies (LibP2P, database)
|
||||
|
||||
## Future Applications
|
||||
|
||||
This network is designed to support applications like:
|
||||
|
||||
- Anchat (encrypted messaging)
|
||||
- Distributed file storage
|
||||
- IoT data collection
|
||||
- Social networks
|
||||
|
||||
When implementing applications, they should use the client library rather than directly accessing network internals.
