A new Bitcoin rule will invalidate blocks with specific 64-byte transaction preimages.
This measure aims to address security issues in SPV malleability and potential ambiguities.
The rule targets only those configurations that closely mimic Merkle node preimages.

The `BoP-2` hybrid signature scheme merges Schnorr-like and arbitrary PQC schemes for enhanced security.
`BoP-2` uses a nonce and a combined hash of messages and signatures to ensure signature integrity.
This scheme enhances security against quantum attacks by relying on theoretical commitment properties.

The investigation into Bitcoin's testnet reveals crucial findings for developers.
A 19-block reorg at height 287766 raises questions about its intentionality and management.
The need for clearer documentation and reorg tracking on the testnet is emphasized.
