I've been working with jl2012 on some SEGWIT BIPs based on earlier 
discussions Pieter Wuille's implementation. We're considering submitting 
three separate BIPs:


CONSENSUS BIP: witness structures and how they're committed to blocks, 
cost metrics and limits, the scripting system (witness programs), and 
the soft fork mechanism.

PEER SERVICES BIP: relay message structures, witnesstx serialization, 
and other issues pertaining to the p2p protocol such as IBD, 
synchronization, tx and block propagation, etc...

APPLICATIONS BIP: scriptPubKey encoding formats and other wallet 
interoperability concerns.


The Consensus BIP is submitted as a draft and is pending BIP number 
assignment: https://github.com/bitcoin/bips/pull/265
The other two BIPS will be drafted soon.

This is the 3rd BIP for segwit. The 2nd one for Peer Services is being

A new BIP, as part of the SW softfork, is pending BIP number assignment:

https://github.com/bitcoin/bips/pull/270

This proposal defines a new transaction digest algorithm for signature 
verification in version 0 and version 1 witness program, in order to 
minimize redundant data hashing in verification (solving the O(n^2) 
issue), and to cover the input value by the signature (a frequently 
requested feature for cold wallet).
