Hello,
Together with Nicolas Vescovo and Ramses Fernandez-Valencia, we have created a new draft RSKIP Peg-out efficiency improvement (Segwit).
The purpose of the proposal is the introduction of Segwit V0 for use in peg-ins and peg-outs to improve performance, cost reductions, and security.
You can find the text of the RSKIP for details here:
