Galaxy0.3.0

Galaxy v0.3.0 Release Notes

This minor release focuses on resolving placeholders, stubs, and dummy logic across services to make the codebase consensus-ready for launch. Key improvements include authentication enhancements, real inter-service integrations, and removal of hard-coded values.

Key Changes

General Improvements

• Updated all services to use dotenv for configurable addresses, reducing hard-coded values and improving deployment flexibility.
• Alphabetized imports in all services for consistent rustfmt compliance.
• Enhanced authentication by passing tokens to inter-service calls in all relevant handlers.

Validation Service

• Resolved block_hash placeholder by integrating get_tx_status from index_service.
• Replaced dummy tx_hashes with real data fetched via new GetBlockByHash endpoint in block_service.
• Added stream_spv_proofs function for streaming SPV proofs.

Network Service

• Replaced dummy IPs in discover_peers with real BSV testnet nodes.
• Completed P2P handshake with VerAck parsing in connect_to_peer.

Block Service

• Delegated block validation to consensus_service with new ValidateBlock handler.
• Added GetBlockByHash endpoint to fetch full blocks for Merkle path calculations.

Consensus Service

• Added ValidateBlock handler with basic POW and tx checks.

Transaction Service

• Resolved index_throughput placeholder with real calculation using indexed_count mutex.

Overlay Service

• Implemented full handlers for create, join, leave, stream, validate, and assemble overlays using sled storage.
• Added BSV-specific validation (32GB block size, 4.3GB OP_RETURN).
• Restored and fixed stream_overlay_data function.

Mining Service

• Added token passing to block_service calls for authentication.
• Restored stream_mining_work function for streaming mining work.

Auth Service

• Loaded roles from config.toml, added default admin roles.
• Removed unused EncodingKey.

Alert Service

• Added authentication and authorization to handlers.
• Stored alerts in sled DB for persistence.

Storage Service

• Replaced dummy blocks in GetBlocksByTimestamp, GetBlocksByHeight with sled storage/retrieval.
• Added GetBlockByHash and StoreBlock handlers for real block management.

API Service

• Added token passing to transaction and index service calls.

Torrent Service

• Added authentication and authorization to handlers.
• Implemented OffloadAgedBlocks with call to block_service, dummy torrent creation.
• Implemented GetProof with call to validation_service.

Config.toml

• Updated version to 0.3.0, date to 2025-08-27.
• Added real testnet DNS seeds.
• Set jwt_secret to "a_secure_secret".

Bug Fixes

• Fixed typos and truncations in previous code outputs (e.g., addr strings, function removals).

Known Issues

• Storage block queries use time as proxy for height sorting; add explicit height storage if needed.

Dependencies

• No changes; compatible with existing Rust crates (sv, sled, tigerbeetle, etc.).

Upgrade to v0.3.0 for improved stability and real logic across services.
