"Demixing" SW 🌀 is not a *thing*. The best an attacker can do is Sybil attack one or more pools (there are 4) 2 currently by probabilistically trying to be 4 of the 5 total participants in a CoinJoin round. At the surface, this doesn't sound difficult, but it is!
Even before the attacker begins, they'll need to split their funds into multiple Samourai Wallets, since there is a maximum number of tx0s that can be created at once. This very act is extremely detectable, but just for argument's sake, let's say they were successful at this.
A CoinJoin round consists of 2 premixers (new entrants) and 3 remixers. So still the attack couldn't begin until they have accounted for being already in a pool while also maintaining being a new entrant. Each new entry pays a coordinator fee, which acts as Sybil prevention.
A fun security property of remixing is anyone who had already entered in a pool and are already remixing aren't affected at all. The attacker can, at best, only learn about premixers after the full scale attack begins, and maintaining the attack has an ongoing cost in fees.
So let's say the attack is ongoing, the attacker knows nothing about existing remixers, they now have to hope that their target enters a pool. Let's say for argument's sake that actually happens. They now have to maintain the attack until their target exits the pool by spending.
This is the hilarious part, and is key to why remixing is important. Remixing has absolutely 0 cost to the target, but maintaining the attack has a significant cost to the attacker because they have to recycle funds to be new entrants again, or they'll lose their target.
This act would also be extremely detectable to anyone monitoring the chain, and the target can literally just chill poolside until the attack stops, get another remix, and move on. Even a single remix breaks links from previous rounds, it's pretty powerful.
Hopefully this helps people understand Whirlpool's security, since it's very well designed.
Soroban is already decentralized and in every dojo today thanks to Pavel the dojocoder.
If soroban is unknown to you here https://medium.com/samourai-wallet/wallet-update-0-99-96-introducing-soroban-adc9a36a7ddb
Whirlpool decentralized client (Java) was ready for beta. Whirlpool decentralized coordinator (Java) was almost ready. but even more important it was being well advanced towards moving 🌀 to a decentralized architecture that uses a single liquidity pool. So every dojo is a coordinator but April 24 2024 prevented that.
