⚡ Bounty: Multi-Node Sync Protocol — 3-Node Consensus Hardening (100 RTC)

[Scottcjn]

Bounty: Multi-Node Sync Protocol

Reward: 200 RTC (~$20 at reference rate)

Background

RustChain runs 3 attestation nodes (50.28.86.131, 50.28.86.153, 76.8.228.245:8099). Each maintains its own SQLite database. We need a proper sync protocol.

Requirements

1. Database sync protocol between all 3 nodes:
   • Sync miner_attest_recent (attestations)
   • Sync balances (RTC balances)
   • Sync epoch_rewards (reward history)
   • Sync ledger (transactions)
2. Conflict resolution: Latest timestamp wins for attestations, primary node authoritative for epochs
3. Sync mechanism: HTTP API on existing port 8099
4. Verification: Merkle root of synced tables
5. Monitoring: /sync/status endpoint showing last sync time per peer

Security

• Admin key required in header for all sync requests
• HTTPS only
• Rate limit: Max 1 sync per minute per peer
• Reject sync that would reduce any balance

Deliverables

• rustchain_sync.py — Sync module
• Updated node code with sync endpoints
• Test script validating 3-node consistency
• PR to this repo

Claiming

Comment with approach and timeline. Major bounty — thorough review expected.
