Hornet adds executable spec for Bitcoin consensus rules
On April 24, 2026, Toby Sharp (@bitcoindudebro) announced a Hornet node update: a declarative executable specification of Bitcoin consensus rules, posted to Delving Bitcoin and Bitcoin-Dev and shared via BitcoinOps.
The change is about representation, not a protocol change: encode consensus logic in a machine-readable, executable form. If complete, that can improve auditability and reduce implementation drift across node software, relevant to Lightning and Nostr integrations that depend on strict Bitcoin behavior.
Open question: the feed notes edge-case coverage and behavioral equivalence remain unproven, and formalization methods do not yet have broad core-dev consensus, so the spec alone does not enforce consensus across implementations.
