Samourai Wallet @samourai_official@mastodon.social

... first bip79++ payjoin (uh probably!) from a Joinmarket wallet:

It gets tagged with UIH, amusingly, but then a lot of transactions probably do.

The rounded amount part is my fault (repeated tries of same amount) 😂

Zooming out and taking in the view after 2 months of mixing. Mobile mixing imminent. https://oxt.me/static/whirlpool_explorer/index.html #Whirlpool #SamouraiWallet

... forgot to add, mean number of counterparties: 5.9

A couple of simple stats from my (extremely slow) Python block parser:

Checked: Approx 375 blocks (so around 2.6 days).
Joinmarket style transactions found: 152.
So average around 58/day ; similar to what I would have guessed (and I think, did in the past, here).

Max size of coinjoin: 54.17 BTC
Min size of coinjoin: 0.00147 BTC
Median size of coinjoin: 1.25 BTC

4 years in operation, still doing like 5-10 coinjoins a day just from my bot (I think there are about 60 active, typically), hundreds of millions (not exaggeration) of dollars worth of btc made more fungible, more than one academic paper analysing it ... but still everyone talks like Joinmarket either doesn't exist or is a dead project.

🤷‍♂️

@harding @Sosthene @FreePietje

Sosthene, I totally agree that this is a subject to be discussed. But this pattern has been repeated over the years. Pretty much all prominent core devs have been super-straight laced.
For example, people you'd expect to be enthusiastic about developing coinjoin decided not to do it (more than one), even though it's a real stretch to imagine that it's illegal or something.

This is a job for nyms, not people, ultimately (gray area for now).

@FreePietje It was pathetic to see him being ignored. Too much back-patting and congratulatory names on t-shirts nonsense going on. Time to get real again. #FuckCapitalControls

@Sosthene @FreePietje 1/ Notification txs are designed to allow full wallet restore from the blockchain. They are not necessary for the address derivation scheme to function. Samourai Wallet is phasing out the use of notif txs altogether. So the "space wasted" via OP_RETURN argument is moot. 2/ Not sure what the "2 txs at least 1 block apart" argument is. Sounds like severe FUD.

@laurentmt

Just to add to the confusion, I'm implementing something I'm calling "payjoin" in joinmarket atm, basically = steganographic tx/p2ep/ etc. No attempt to address the merchant use-case, just wallet-wallet.

I think everyone eventually comes round to the idea that this is a very desirable kind of coinjoin :)

Thanks for linking this on birdsite, I think I must have skipped or missed it when you wrote it https://gist.github.com/LaurentMT/e758767ca4038ac40aaf

Unapologetic idealists have perhaps the best chance of changing the world. Bitcoin has been built by such people, and it offers a revolutionary way of storing and exchanging value.

Thankful for projects like @samourai_official that recognize this, and are willing to take risks instead of just pandering to the masses. Removing fiat conversions really is just a small thing, but the ideal is preserved and promoted.

Just lurking around and testing how Mastodon works.

Here is a 2-wallet Samourai Stowaway spend. Neither output displays the true spend amount which is, in effect, "stowed away" via a trusted cooperation between 2 wallets.
