Show HN: Rust blockchain with sharded propagation and post-quantum signatures

3 days ago

Alphanumeric network features a resilient discovery and light snapshot layer.
Nodes announce their status, clients discover peers, and gateways ensure reconnection and sync.
Network operations include live gateway telemetry, chain health signals, and recent activity monitoring.
Snapshot history is currently unavailable (24h).
Nodes publish signed status and optional stats snapshots.
Gateway deduplicates endpoints and prioritizes fresher peer signals.
Header snapshots transition from pending to verified via signer quorum.
Clients sync from the canonical chain tip using discovery APIs.
Discovery involves nodes POSTing signed announcements and clients fetching ranked peers.
Light snapshot includes validators submitting signed header snapshots with height and timestamps.
Health checks include a simple uptime endpoint and CORS-friendly APIs.
To run a node, set ALPHANUMERIC_DISCOVERY_BASES, keep the binary online, and expose ALPHANUMERIC_STATS_PORT if hosting stats.
Recommended environment variables provided for node setup.
Example of a signed announcement payload with node details and signature.
