The Transaction Size and Fees section says a P2MR witness is always 32
bytes smaller than an equivalent P2TR script path spend witness. The
control blocks are 1 + 32*m and 33 + 32*m bytes, each serialised with
a compact size prefix, so at m = 7 the P2TR control block is 257 bytes
and takes a 3-byte prefix while the P2MR one is 225 bytes and takes 1.
The saving there is 34 bytes, not 32. Every other depth up to 128
gives 32.
The section already footnotes this boundary for the P2MR side a few
paragraphs earlier.
- The Test Vectors section linked P2MR_construction.json; the file on
disk is lowercase p2mr_construction.json, so the link 404s.
- The same section still linked the rust implementation under
bip-0360/ref-impl/rust, which #2202 moved out of the repository.
- The header said Version: 0.12.0 while the changelog's latest entry
is 0.12.1.
- The 135-byte depth-1 witness example labeled the merkle path
"(empty)" while counting 32 bytes for it (a depth-1 path has one
32-byte node).
Both BIPs added a changelog entry on 2026-01-23 referencing the updated
BIP Process meta-BIP with the wrong form:
- bip-0360.mediawiki:404 rendered `[[bip-0003.mediawiki|BIP 003]]`, but
the actual file is `bip-0003.md`. The MediaWiki link therefore failed
to resolve to the BIP 3 page on the bitcoin/bips GitHub wiki render
and on the bips.dev / bip339 style mirrors — readers of the bip-0360
changelog landed on a 404.
- bip-0347.mediawiki:170 wrote the same reference as bare text
`BIP 003` with no link at all, so readers of bip-0347 had no way to
navigate to the BIP 3 they were meant to follow.
Rewrite both entries to use the canonical form `[[bip-0003.md|BIP 3]]`:
- `bip-0003.md` matches the actual filename.
- `BIP 3` matches the display text convention the README (line 40) and
every other BIP in this repository already use when linking to
bip-0003 — "BIP 003" with the three-digit zero-pad appears nowhere
else in the repo for any BIP and is not part of the display style
described in BIP 2.
Also drops the trailing whitespace on the bip-0347 line while we are
there (the `typos` CI tolerates it but it is inconsistent with every
other line in the same changelog block).
