This is probably a blog post of some sort, but I'm snowed under so just writing it here:

I think at a cursory glance, people overestimate Joinmarket's effectiveness, especially against *targeted* attacks, but if anything underestimate it when they take a deeper look.

Consider the idea of a targeted attack on a maker, identified e.g. through having done one coinjoin with them and knowing some utxos (say, just 1 for simplicity).

"Targeted" attack could just mean, acting as a taker, ... (1/n)

yay, tests finally green on the addrman "rewrite"... it's time for a sunset surf

my understanding of addrman.{h, cpp} is inadequate, so spent half the day pulling the code apart, rewriting, and putting it back together. baby steps, slowly but surely

Is your RAM ECC? This comment (and the linked discussion) are about how a single bit flip from a cosmic ray (e.g.) can entirely bork a "blockchain" (in this case Certificate Transparency, used for monitoring internet PKI .. one of the very rare examples of applying the blockchain paradigm outside of bitcoin, that does ~ make sense).

People in that thread are arguing about what and where ECC is needed, I confess a lot of ignorance about this.

It's technically still a bash one-liner! 🤣

Imagine if the international community started refusing ALL extradition to countries with inhumane prison systems.

The El Salvador bitcoin bill was just voted, passing by supermajority and to applause in the El Salvador Congress. El Salvador is the world’s first bitcoin nation!

How many mistakes? Reused address. Round amount. Mixed script types (not sender's fault). Then receiver sends straight to exchange with zero obfuscation.

Honestly tinfoil may be required in the face of this 🤡 behaviour.

Incredible to see the total lack of simple comprehension on the part of people speculating about the FBI seizure of the ransomware coins. None of them should be anywhere near any advice-giving, any recommendations, any financial suggestions, whatsoever, ever.

I wrote this on 1st Feb 2020, probably a week or two after I first heard about the virus:

Apparently the "lab theory" is not nonsense (who woulda thought it!), but that's not the story, the story is that well over a year later, most of our friends are still using the cancer that is corporate/SV social media, that would indeed, and regularly did, "cancel" people for expressing this opinion.

Shame.

RT @pwuille
In version 0.21 @bitcoincoreorg added support for Tor V3: twitter.com/pwuille/status/131

For the next major release we're dropping V2 support. Their usability will rapidly diminish the next few months, as they're deprecated and @torproject will soon remove support. twitter.com/BitcoinMerges/stat

libera's matrix bridging functionality works surprisingly well, to access bitcoin-core-dev through a matrix (instead of IRC) client you can use:
matrix.to/#/#bitcoin-core-dev:

when you push an update at midnight but can't get to sleep until 2 am to see if the CI run is green

At next Wednesday's Bitcoin Core PR Review Club, we'll be looking at PR 21527 "Net_processing: lock clean up" (p2p).

Come discuss and learn about orphans, peer message handling, and mutexes for locking and thread safety.

Notes and questions are up. Thanks to John Newbery for hosting!

In Romania there is a proposal to rename the street with the Belarusian embassy "Roman Protasevich street".

So they won't be able to even give out the address of their embassy without wearing the shame of hijacking an international flight to kidnap a journalist. Brilliant 😂
