Hi all,
I have put up an initial draft of the full 'bip-genvbvoting' (generalized version bits voting) specification for review:
https://github.com/sanch0panza/bips/blob/bip-genvbvoting/bip-genvbvoting.mediawiki
Comments are again most welcome - and my thanks to those reviewers who took a look at the initial rough draft [1].
A prime goal is that this BIP proposal should end up allowing full backward compatibility with the existing BIP9 state machine, if wishing to do so for a deployment. In fact, this will be necessary to maintain full compatibility with any ongoing deployments.
I will work on a reference implementation which might also turn up inadequacies of the proposed specification. A link to this will follow once it is mature enough for review.
Sancho
