That's the note ABOVE my reply (which remains unaddressed), not a note BELOW it:
#nevent1q…qr0t
Coordinator fees do not protect you at all against a Sybil attacker if the coordinator is part of your threat model 🙄
Mining fees are protect you against a Sybil attacker, and Whirlpool is especially vulnerable to Sbil attacks because THE ATTACK VICTIMS PAY THE MINING FEES FOR THE BLOCK SPACE USED BY ATTACKERS.
The coordinator fee incentives of tx0 give Sybil attackers an advantage over regular users because they get a DISCOUNTED COORDINATOR FEE for splitting their coins and participating in more rounds compared to consolidating into bigger pools.
The worst part is, none of this Sybil attack discussion even remotely touches the original point, which is how premixing is HARMING privacy while WASTING block space:

Whirlpool makes the situation horribly worse by wasting block space with "premix" and "postmix" transactions 💩
WabiSabi coinjoins allow you to mix and send directly to your destination in a single transaction, without leaking common input ownership and without creating any unspendable "toxic change" 🎭

WabiSabi coinjoins are far superior to Whirlpool coinjoins. You get complete privacy on your entire balance, there is no "bad bank" that makes your transactions traceable like Whirlpool.
WabiSabi coinjoins are available in Wasabi Wallet, BTCPay Server, and Trezor.

Wasabi Wallet works as an interface for your Ledger: https://github.com/zkSNACKs/WalletWasabi/blob/master/WalletWasabi.Documentation/WasabiCompatibility.md
Bonus: You protect your IP address from being associated with your transactions since Wasabi uses Tor for all communication by default.

Yes. BTCPay Server's WabiSabi coinjoin plugin allows you to discover coordinators and mix your funds between them: https://docs.btcpayserver.org/Wabisabi/#additional-coordinators

You should try a WabiSabi coinjoin with Trezor, BTCPay Server, or Wasabi Wallet. There's no coordinator fee for inputs under 1 million sats, and less block space/mining fees required.

Lots of things are very wrong in that chart. For example, Wasabi doesn't have change outputs at all, has a flat fee, has free remixing, has postmix spending tools, etc.

Wasabi Wallet for on chain transactions. It has coinjoins built in which makes it so no two transactions you send or receive are ever able to be linked to each other.

I wish there was a chart that tracked the total supply of Bitcoin UTXOs that have a negative value if transferred at the median fee rate for that day.

I tried this approach, but the opinion of the Samourai developers is that privacy MUST be opt-in by default, not opt-out by default. They said any PR to make privacy features enabled by default would not be merged: https://code.samourai.io/wallet/samourai-wallet-android/-/issues/458

I can only thing of one instance in which merging post mix coins could create a near deterministic link, which would be if you sent a single UTXO to an empty wallet, coinjoined for a single round, then swept the resulting UTXOs to cold storage.
This edge case correlation is prevented if you register a second UTXO (especially if the second UTXO is already private), remix any UTXO from the first round, or merge your coins in two separate transactions when spending.

2023-03-26 03:53:33 CEST

What sort of actions in Wasabi would undo the benefits of your coinjoin? If you have both non-private and private coins in your wallet at the same time, the wallet selects your private inputs when making a payment.

2023-03-26 03:51:55 CEST

- reply

Correct. Tor is already bundled with Wasabi so you get privacy out of the box without any other configuration needed.

2023-03-25 12:42:05 CET

You should just use WabiSabi coinjoins instead of Whirlpool coinjoins so doxxic change is never created at all.

2023-03-17 19:32:36 CET

- reply

This is a lie. All Whirlpool coinjoins can be unpeeled to reveal this change, it's trivial to do because of a fatal privacy flaw called 'tx0' that merges your coins without yourself instead of coinjoining them first.
Go ahead and post any example of a Whirlpool transaction on the blockchain, I can easily unmix the change created by the new entrants:

Kortik, you are lying again. Every single line of Wasabi's coordinator code is free and open source software, ANYONE can run their own coordinator just like they can run their own wallet: https://github.com/zkSNACKs/WalletWasabi/tree/master/WalletWasabi.Backend

2023-03-11 03:17:43 CET

Yes. And even worse than a regular self transfer, the ricochet chain of transactions is initiated with an on chain fee payment to Samourai, which rules out any guess that the transactions are payments instead of self spends.

2023-03-11 00:37:29 CET

That address belongs to a remixer, not a new entrant. Whirlpool inputs 1, 4, and 5 leaked their doxxic change in a previous round, only Whirlpool inputs 2 and 3 leaked their doxxic change from this round.

2023-03-10 19:30:54 CET

- reply

The initial mix in Samourai is immediate because you are the taker of liquidity instead of the maker of liquidity. As a remixer, your coins can't move until someone else pays to move them for you.

Anti-samourai Bitcoiners are warning others about how Whirlpool works since we are easily able to unpeel the deterministic links from the tx0 premix:

Wasabi makes EVERY spend a coinjoin instead, so you never reveal any other addresses belong to you:

Would it be fair to blame the user if they imported the seed into a second client running simultaneously? This would cause address collisions since each client is not aware of transactions the other is signing.

What do you mean? Coordinator fees are not a part of a coinjoin's security model at all. They are a completely optional revenue stream.

There is no unmixed change in WabiSabi coinjoins, while there is traceable change left behind from Whirlpool tx0 transactions.

2023-02-26 14:28:51 CET

- reply

Samourai's Whirlpool is extremely expensive to use compared to Wasabi Wallet's coinjoins, so it's a bad example IMO. Wasabi's coordinator fees max out at 0.3%, and amounts under 1 million sats don't pay any coordinator fees at all.

2023-02-26 14:25:37 CET

- reply

Wasabi Wallet does this already. To further protect your network level privacy, each block is downloaded with a single use Tor identity as well so there's no way to even associate multiple blocks to a single wallet.

2023-02-22 02:59:48 CET

- reply

Have you tried the 2.0 version of Wasabi? Coinjoins run passively in the background, don't produce any identifiable change outputs, and doesn't require the user to perform any coin control (even for consolidation, since that is done within a coinjoin).
Here's a short demonstration:

If the default mempool does not include the highest bidding transactions (due to standardness rules limiting size), it makes sense for a miner to accept these transactions out of band in order to maximize the fees from the blocks they create.

This seems like it could be partially fixed by nesting a new npub in the initial message and response.
