Purpose

Aggregator directory for networking protocol extensions that build on top of the core blueprint-networking P2P layer. Each subdirectory is an independent crate providing a specific multi-party protocol pattern (signature aggregation, round-based MPC, or shared gossip primitives).

Contents (one hop)

Subdirectories

• agg-sig-gossip/ - blueprint-networking-agg-sig-gossip-extension: signature aggregation over gossipsub using blueprint-crypto aggregation primitives and bitvec signer bitmaps
• gossip-primitives/ - blueprint-gossip-primitives: reusable gossip protocol building blocks (message deduplication via LRU/blake3, async round management, optional live libp2p transport); used as a foundation by other extensions
• round-based/ - blueprint-networking-round-based-extension: adapter integrating the round-based crate with blueprint-networking for multi-round MPC protocols over P2P

Files

• (none)

Key APIs (no snippets)

• Signature aggregation gossip protocol (agg-sig-gossip)
• Gossip message primitives with deduplication and round tracking (gossip-primitives)
• Round-based MPC protocol adapter over blueprint networking (round-based)

Relationships

• All extensions depend on blueprint-networking and blueprint-crypto
• agg-sig-gossip depends on gossip-primitives
• These extensions are consumed by blueprint services that need multi-party computation or aggregated signatures
