Subject: Re: [Bitcoin-development] Proposed BIP 70 extension
Date: Wed, 25 Jun 2014 14:10:58 -0400 [thread overview]
Message-ID: <CAJHLa0MaoG2gDkgEkTuV0d3U1=p2Zmr4E-kO=qowpZeRY0q7Ew@mail.gmail.com> (raw)

Remember the IETF RFC process.
1) RFCs are never updated. Extensions go into new RFCs.
2) Build an implementation, write a draft, circulate both. Then get a
BIP number.
3) As MH indicated, it would be useful to have a living payment
protocol document that _is_ updated.
4) Let's stop calling it BIP70. That just reinforces the desire to
update the BIP70 document.
