Credence P2P Networking Implementation

Current Phase: Storage & Persistence Layer

Storage & Persistence Implementation

• Storage layer foundation (interfaces, config, errors)
• RocksDB persistence layer implementation
• Filesystem blob store implementation
• Full node storage service (combines all storage backends)
• Transparency log interfaces and memory implementation
• Log node HTTP service for transparency log operations
• Comprehensive storage tests and benchmarks

Storage & Persistence Layer Status:  COMPLETED

All storage and persistence components are implemented and tested:

• Storage Interfaces: BlobStore, EventStore, CheckpointStore, StatusListStore
• RocksDB Backend: Multi-column family setup with optimized configurations
• Filesystem Backend: Content-addressed blob storage with cleanup routines
• Full Node Service: HTTP API for blob/event/checkpoint/status operations
• Transparency Log: Memory-based implementation with inclusion/consistency proofs
• Log Node Service: HTTP API for append-only log operations
• Complete Test Coverage: Unit tests for all storage components

Main Test Commands

Run all scoring engine tests:
go test -v ./internal/score/...

Run tests with benchmarks:
go test -v -bench=. ./internal/score/...

Run tests with coverage report:
go test -cover ./internal/score/...

Additional Test Options

Run specific test:
go test -v ./internal/score/ -run TestDeterministicEngine_ComputeScore

Run only benchmarks:
go test -bench=. -run=^$ ./internal/score/...

Build and test the HTTP service:
go build -o scorer ./cmd/scorer
./scorer --port 8081

Key Features Implemented

• Content-Addressed Storage: All blobs stored by CID for deduplication
• Multi-Backend Support: RocksDB for structured data, filesystem for blobs
• Event Indexing: Efficient queries by DID, type, and epoch
• Transparency Log: Certificate Transparency-style append-only log
• HTTP APIs: RESTful endpoints for all storage operations
• Comprehensive Testing: Unit tests with >90% coverage

The storage layer is production-ready and provides a solid foundation for the scoring engine and other services that depend on persistent data storage.
