I think the concept itself is pretty solid. I know some people have been proposing alternate methods too. I hope they'll share here, assuming they haven't already. As is, my comments concern typos and general copy editing. - - Just speaking in general, I found the BIP to be a bit hard to read. AFAIK, the basic facts are accurate. I just found myself having to re-read certain passages two or three times. A little polish wouldn't hurt. For example, using the "it" pronoun can be confusing, such as multiple uses in the abstract. Specifying what "it" is (e.g., "The proposed change relies on...") would really help. In addition, the way the "W" value is handled seems like it could be improved a bit. I know the wording is accurate. Seeing 1000 change to 1001 is still a little weird. - - In "Multi-stage soft forks," I presume the second sentence should end as follows: "[...] with additional validation rules that get enabled one by _one_." Depending on semantics, I'd consider changing "one by one" to "incremental steps," but that's your call. - - I found the "High bits" section to be confusing at first. It looks like you chose to show everything as little endian data, matching what's actually in the block. My personal preference would be to represent the data, for readability purposes, as big endian. I doubt I'm the only one who finds big endian to be much easier to process mentally. - - Some sort of legend showing A, I, W, etc. would really help, as opposed to just running into them as one goes along. Otherwise, the alphabet soup can be a bit confusing. Thanks again. - --=20 - --- Douglas Roark Senior Developer Armory Technologies, Inc. doug@bitcoinarmory.com PGP key ID: 92ADC0D7 -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.22 (Darwin) Comment: GPGTools - https://gpgtools.org iQIcBAEBCgAGBQJVZSx5AAoJEGybVGGSrcDXrYEQAOIrsggoZv0LdJHZjPGpEkeb 7ULhO4krZtQmKXjWDP0KnHAsFiyo5EOh1fYFRZz11OCqO4QmteTLPbodZFz47tKp tIYv5uc0qYhjfo5uLkzxuUky08VE4dUoELfqdbNciC45xHras7Wh/+KXc1a20Fib TaisWx9aL6VfPf7urM8b6mQ9XMba4YB3e2syAY8AA+qAEEP4DK2V6tuOQJD3kxP2 tbHtJnDvkDoXEY6tnL7fePo9X/IrlXLi8vNWGqPIf/hoiHmdvU+ORwHta7z9YeIO zi4LRs8n8sYmifY4nt6Wkkc1aoPsmpoXmI3tKgFM2h5bfdg0n3fN3K0nTMWtnR6z HUq8JhrQkZUP8uunN/23bt94FZolvnHTdL9YuWoyrlJ0gQri5YxV1BAN4hM9oCZy 1SqlSmFRplIFWu45q8/I5duDSphmA4NP2qc59QRjftcGYpNxmzaeSViiCDWzAjI9 qTLZgLTa/nf3TFN8oU8RwquGpwD82/fFo9V+uKdNGj79kdV8WOv4sa9q63OTVimJ w+r4l1gDZYyToe0heKtV2kL9Tt4HTn23bj7EvU+98uaKEpfWSP8a3BN9mPR7ork/ lNRGEGQ0tvkeDUzKy9IHuAjXo2XkKctbBRJwZJCGc5WW2sN0HdSu/GFPXrOOLf0J JXqeKpfaS0UriFXkxVHO =3D8uNL -----END PGP SIGNATURE-----
