What changed, and why it matters
This is a tiny code cleanup in a Bitcoin transaction serialization helper. It removes an unused bytes-to-hex function and avoids creating an empty COutPoint object before deserializing one. There is no apparent security issue.
No action required; treat as routine refactoring.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The commit removes the unused bytes_to_hex_str() wrapper and eliminates a redundant COutPoint() instantiation in CTxIn.deserialize(). The prevout field is already initialized elsewhere (likely in init), so the removed line was unnecessary object creation. No cryptographic, parsing, or memory-safety behavior changes are visible in the diff.
