Speed:
- Bolt12ZapValidator reorders checks cheap-to-expensive: all structural, cross-event,
and payer-proof binding checks run first; the schnorr signature + proof crypto
verifications run only once an event has passed them. A malformed or mismatched
event now rejects with zero schnorr ops. Cannot change accept/reject, only which
reason a doubly-invalid event reports.
- validate() gains verifyEventSignature (default true); LocalCache.consume passes
false since the relay pipeline already verified the outer event — removing a
redundant schnorr on every ingested zap (3 verifies instead of 4).
- Bolt12Merkle precomputes SHA256("LnLeaf")/SHA256("LnBranch") once and hashes the
per-call "LnNonce"||first-tlv tag once per rootHash instead of once per record.
Tests:
- New validator rejections: preimage-mismatch, invalid-invoice-signature,
payer-tag-mismatch, proof-does-not-match-offer, plus the verifyEventSignature
skip-flag both ways (fixture gains corruptPaymentHash / breakInvoiceSignature).
- New commons NoteBolt12ZapTest: millisat→sat total, dedup by payment_hash,
verified-not-downgraded-by-unverified, remove-by-source, clearChildLinks, and
combined totals.
Docs: quartz/plans/2026-07-23-bolt12-zap-interop-vectors.md captures the two
upstream-gated follow-ups (vector-driven interop test + compressed-proof merkle
reconstruction) for when lightning/bolts#1346 merges.
