Joinmarket 0.6.1 bugfix release out

(bug was basically deposits not showing, without a rescan, if there are a lot of them because of a failure of the address import mechanism)

@jon nice job on the Livera podcast!
Not enough chat out there about open source bitcoin development.

Interesting thoughts here .. the scriptless script construct gives a lot of flexibility in how LN channels can work - like Jonas I remember being very struck by Conner's talk on this last year:

New way to help fund my #Bitcoin work, for the folks who are boycotting Patreon but would still prefer to contribute in fiat currency.

(GitHub also *doesn't* have Patreon's 10% fee, and will even match contributions for a while!)

@jon That makes perfect sense.
Buzzwords and technobabble lobbied at VC's that don't understand tech. Add famous autistic geniuses, the right packaging and you got investments.

@Sosthene @jon Voskuil's arguments are silly IMO. He's arguing that encryption without authentication provides no value (because you can be MITM'd) but Schnelli's protocol makes it possible to detect MITM. Voskuil discounts this because he thinks nobody will attempt detection, but if even one person does, we have a more private protocol than we have today. Moreover, with encryption available, performing authentication too becomes much easier (e.g. no more need to use Tor for that).

Great session of Bitcoin #pr-review-club hosted by @jon today, besides the technical aspect (tbh honest I still feel a bit short on that) I have been particularly interested to hear Jonas Schnelli (is he here btw?) making his point about the benefits of P2P encryption, even if tbf I'm still not entirely convinced, Eric's arguments still looks quite strong to me. I still need some time to make my mind.

I set up a little bot that toot quotes from the Cypherpunks old mailing list : @Cypherpunks_mailinglist
I originally intended to make it tweet and toot at the same time, but when I created the @[email protected] account, it got locked up for "breaking the terms of use" in literally 30s. WTF? I barely created it, how could I break any rule?
And guess what? They demand a phone number to give it back to me 😂
So yeah, it will be Masto only 🖕

At tomorrow's Bitcoin Core PR review meeting, we will be looking at PR #16202 "Refactor network message deserialization" by Jonas Schnelli. It's been a high-priority PR for some time. Please review the PR and prepare the notes and questions before the meeting if you can. See you tomorrow!
