Bitcoin Knots
Bitcoin Knots is an enhanced full-node implementation of Bitcoin, maintained by Luke Dashjr. It builds on Bitcoin Core with additional privacy, decentralization, and mining-related features.
Key Differences from Bitcoin Core
- Enhanced block template options — more control over transaction selection for mining
- Spam filtering — stricter mempool policies (notably the "inscriptions" debate)
- Privacy hardening — additional RPC toggles and defaults
- More conservative defaults — prefers decentralization over convenience
Role in Mining Stacks
- Required node software for DATUM-based template construction
- Provides the mempool and UTXO set that DATUM uses to build custom work
- When combined with AxeOS and Ocean.xyz, creates a fully miner-controlled pipeline
Installation Context
- Packaged for StartOS as a system service
- Can run on any Linux/macOS/Windows server with sufficient disk and bandwidth
- Pruning supported but not recommended if serving miners (full chain validation matters)
Relationship to Start9OS / StartOS
- StartOS is the operating system
- Bitcoin Knots is one of the services you run on it (alongside C-Lightning (Core-Lightning), BTC RPC Explorer, etc.)
