Taxes are a scam. Inflation is a stealth tax. Bitcoin fixes this.

New record sized coinjoin for my coordinator - 377 inputs/413 outputs: https://mempool.space/tx/5d238e5bd251d55f4b83c10a9834265e59acc48d6027c68d6dc197cec15f7305

18 outputs means you created change. If you are acting as the taker, you should always sweep to terminate the trail of linkable funds in that mix depth.

Reminder: Your money is not subject to the authority of voters. Do not pay any taxes to this mob of thieves.

These transactions are created with either Wasabi (https://wasabiwallet.io/) or BTCPay Server's coinjoin plugin (https://docs.btcpayserver.org/Wabisabi/).

>First of all, you have failed to demonstrate any Samourai Wallet "address reuse bugs" that can be equivalently compared to the systemic & symmetric address re-use vulnerabilities in Wasabi although you claimed them to be equivalent on Vlad's podcast.

Why can't they be compared? I just compared them didn't I? Your comment that Whirlpool's toxic change outputs and coordinator fee outputs already have such terrible privacy that it doesn't make any difference whether or not the addresses are reused doesn't help your argument, it hurts your argument.

>As for Ergo's tweet, when he says "unmixed" change, he's talking about change that comes out of a Wasabi CoinJoin tx

Okay, and when I say "unmixed" change I'm talking about the change that comes out of a Whirlpool tx0.

Now that we are both on the same page, please explain why you wouldn't just solve the problem of unmixed change like Ergo suggested by never creating it in the first place? I even opened a Gitlab issue in Samourai's wallet for doing this: https://web.archive.org/web/20231025112756/https://code.samourai.io/wallet/samourai-wallet-android/-/issues/461

Sounds like you are just talking shit, let's see if you can prove it by tracing my Wasabi coinjoin payment: https://x.com/Kruwed/status/1835105451555312041

If you could then you would have but you can't because you're out of your depth. None of your examples are the result of address re-use in the CoinJoin. Unlike Wasabi's systemic & symmetric address re-use vulnerabilities which both occur in the CoinJoin transaction.

To clarify further: in your first example above, the coordinator fee is provided during the tx0 transaction while the wallet is setting up for and prior to the CoinJoin transaction. Tx0 transactions have obvious on-chain fingerprints and I fail to see how identifying the address used by the coordinator to collect the fee has any bearing on the anonymity of the user.

In your second example, the re-used address was also re-used in a Wasabi CoinJoin tx so that doesn't help your case but more importantly, when it was re-used by Samourai, it was in the tx0 - not the CoinJoin transaction. Additionally, based on the comments in that thread, the wallet was imported to Samourai and admittedly wasn't fully synced.

Finally in your third example and like the others, this was not a case of address re-use in the CoinJoin transaction (unlike Wasabi) but rather limited occurrences of address re-use in post-mix spending tools like Stowaway, Stonewall, & Stonewallx2. As explained in Samourai Wallet's write up of their investigation into the reported issue: not nearly as many addresses were effected as originally claimed and for good measure Samourai Wallet introduced Strict Mode after this report to mitigate unintentional address re-use by the users when transacting with post-mix spending tools.

Despite your efforts to equate Wasabi's address re-use vulnerabilities to Samourai Wallet, you have come up short yet again.

So since you are aware of all of Samourai's address reuse bugs, then please explain to me why anyone would want to create "toxic change" instead of becoming fully untraceable? The WabiSabi protocol solves the "peeling chain" privacy leak that is produced by the Whirlpool protocol: https://x.com/ErgoBTC/status/1181573118810361856

As I mentioned, there is a non-zero chance Wasabi's systemic address re-use vulnerability will send a mixed output to a previously used change address, that's one reason choosing Wasabi would have been a poor choice. Another is that there is also a non-zero chance that Wasabi's symmetric address reuse vulnerability will include the same address on both the input & output sides of the mix. Additionally, fees paid to Wasabi helped support chain analysis companies; utxos are ground to dust if left to CoinJoin for too long; and now that ZKsnacks' coordinator liquidity has been broken up among several new coordinators, users can enjoy dancing with themselves in shallow liquidity pools that offer no practical anonymity benefits.

Further more, the existence of doxxic change makes no difference when a user is intentionally sending all their outputs to their pre-mix wallet (of all places) and then consolidating them. To even achieve what you've demonstrated the user would have to put in considerable effort to make such a mess of things.

Your example is one of intentionally destructive user behavior and this entire exercise has demonstrated that you are purposefully attempting to misguide people and/or you have little to no grasp on the subject. Despite your inability to identify that example as a blatantly obvious and intentional maneuver to consolidate outputs, you chose to confidently use it as an example to equate the vulnerabilities in one wallet with the deliberate choices made by the user in another wallet. The fact that you have been engaging in tactics such as this for years is disturbing and the fact that you continue to do so after the Samourai Wallet coordinator has been shut down is deranged.

I can reply to your wall of text, but it seems you are confused. Here's 3 different instances of address reuse in Samourai:

Samourai coordinator address reuse: https://x.com/Kruwed/status/1735129375001968838

Samourai toxic change address reuse: https://x.com/brian_trollz/status/1559018534675644418

Samourai postmix address reuse: https://x.com/SamouraiWallet/status/1283145015124996098

Not sure what you are looking for with 'entropy', but you can use this open source tool to measure the anon sets of WabiSabi coinjoins with 150+ inputs: https://github.com/turbolay/WabiSabiAnalyzer

Aren't rollups worthwhile since they can be combined with other layered proposals to extend their scalability?

If I'm wrong, why don't you prove it? I already gave you an untraceable coinjoin transaction, how about you try tracing it?

Look at the transaction I posted and see for yourself.

Literally anywhere to spend it. There is zero adoption in my entire region.
