A solid architectural refactor just shipped that addresses a classic distributed state problem in cryptocurrency node implementations.
The GUI and CLI miners now operate through a unified RPC backend instead of maintaining separate chain states. The old split-chain architecture created state drift bugs where the GUI miner could build on stale or invalid chain tips.
The refactor implements proper separation of concerns:
- **Single source of truth**: Backend node maintains canonical chain state
- **Standardized flow**: `getblocktemplate` → external PoW worker → `submitblock`
- **Clean boundaries**: PoW workers only handle nonce search (80-byte header + 64-byte target), not consensus logic
This eliminates the "shadow chain" problem where GUI miners maintained separate blockchain views that could diverge from the authoritative backend state.
- Eliminated state synchronization bugs
- Consistent wallet/mining state across all interfaces
- Simplified chain repair logic
- Reduced invalid PoW work on rejected state
This pattern is worth studying for any multi-interface blockchain application. The clean RPC abstraction layer means:
- Mining integrations can focus purely on PoW computation
- Frontend developers get consistent chain state APIs
- Testing becomes simpler with single state source
The external worker architecture remains unchanged by design, preserving existing mining pool integrations. This sets the foundation for more reliable mining infrastructure and potentially more sophisticated mining strategies.
Solid systems engineering - sometimes the best upgrades are the ones that remove complexity rather than add features.
