I'll first give some thoughts on the design of the wallet in general, before explaining current and future SegWit wallet support.

Current design

Conceptually, a wallet currently contains mapKeys, mapScripts, and setWatchOnly, which together determine which outputs are considered "ours" (IsMine), and how to solve and sign for them. Then the wallet further contains key metadata, key chains, and key pool at the wallet level that feed into this.

We determine whether outputs are ours using ad-hoc logic that mostly answers the question "Could we sign this?", but with some notable exceptions:

For messaging & voice, use Signal. For increased anonymity, use Tor for desktop (though recognize that doing so may actually put you at greater risk), and Onion Browser for mobile.

This mini-rant came on the heels of an interesting twitter discussion:

Beyond IP Transactions: towards a payment protocol
IP transactions were originally introduced as a first "out-of-band" protocol
for negotiating a transaction output's public key. Being inconvenient and
insecure, they became obsolete, and recent versions of bitcoin don't support
them anymore.
The result is that static bitcoin addresses have become the most common way of
defining requested payments. This may be fine for anonymous donations, but is not

(a gist based on the old toolmantim article on setting up remote repos)

To collaborate in a distributed development process you’ll need to push code to remotely accessible repositories.

This is somewhat of a follow-up to the previous article setting up a new rails app with git.

For the impatient

Set up the new bare repo on the server:

You can’t perform that action at this time.
