crypto: add generic SipHash-1-3-UJ

This commit adds a new, weaker variant of the SipHash algorithm inside Bitcoin Core's cryptography module. It is explicitly designed for low-security uses such as internal hash tables, not for protecting funds or network messages. The code…

test: add SipHash-1-3-UJ coverage

This commit only adds new test cases and fuzzing coverage for an existing SipHash variant called SipHash-1-3-UJ. It does not change any production code, so it cannot introduce a security vulnerability or fix one. The change makes the softw…

crypto: add fixed-width SipHash-1-3-UJ

This commit adds two new shortcut methods for computing a specific SipHash variant on fixed-size inputs. It is a pure performance/ergonomics addition: the new methods copy the hasher's internal state before operating, so they do not alter …

A Bitcoin Core developer removed their own DNS seed (seed.bitcoin.sipa.be, run by Pieter Wuille) from the list of hardcoded network seeds that help new Bitcoin nodes find peers when they first start up. This is a routine operational/mainte…

clusterlin: update SFL comments for deterministic order

This commit only changes comments in a single source file. It updates documentation to describe how transaction ordering is chosen when multiple equally-good options exist. No actual code behavior was changed, so it cannot affect security …

doc: mention Miniscript expressions inside reference

This is a one-line documentation update that adds a reference to Miniscript expressions in the descriptors documentation. It does not change any code, executable logic, or configuration. There is no security relevance.

doc: do not list descriptor RPCs or history

This commit only edits documentation. It removes a list of Bitcoin Core RPC commands that support output descriptors and shortens the introduction. No code, RPC behavior, or security logic was changed.

This is a code-cleanup change in Bitcoin Core that replaces confusing custom comparison operators on a fee/size data structure with clearly named wrapper classes. It does not fix a known vulnerability or change network behavior; it is a re…
