Idea is that you go from a "vault" state to "unvault" state to "spend" state via the hot wallet keys, with a fixed delay between unvault/spend, and the ability for the cold wallet holder to verify that the spend tx is valid, and if it's not for the cold wallet holder to be able to recover the funds during the delay, before they're lost/stolen/etc.
Spend:

What do you think of just generalising feature negotiation so it's comprehensive?
Suppose "VERSION 80000+" specifies:
initiator sends a VERSION message responder sends a VERSION message
after having both send and received a VERSION message specifying a version >= 80000, both nodes must specify FEATURE support by

As an idea to make it easier to keep track of review work for P2P related stuff, maybe we could use a github project as a dashboard.
Turns out you can do this on a personal project board by creating notes saying things like "bitcoin/bitcoin#16401" and it turns into a bitcoin PR like magic. So I've made a trial:

Should make it easy to pick what to work on:

| Hard-forking Changes to Bitcoin Core | |
| ==================================== | |
| A hard-fork change to the Bitcoin consensus validation rules is one that | |
| treats previously invalid blocks as valid. (Such a change may additionally | |
| include soft-forking changes, treating previously valid blocks as invalid) | |
| In order to safely deploy a change of this type, the following process | |
| should be followed: |
