Whirlpool requires the use of a blinded coordinator server to pass messages between clients. This server doesn't and crucially cannot know the contents of the messages it is passing.
Whirlpool is different than other CoinJoin services, in that you do not pay a volume based fee per anonymity set, but instead you pay a one time flat fee for an unlimited anonymity set. You do pay a miner fee for each UTXO created after Tx0.
You can use WhirlpoolFees.com to get an estimate of your mixing fees.
To put it simply, it costs the same in Pool Fees to cycle 1 BTC or 35 BTC. Once the pool fee is paid, it costs nothing to continue cycling. With each cycle you gain a greater privacy advantage with a deeper anonymity set.
The pool determines the minimum and maximum amount you can cycle through that pool and what the denomination the mixed outputs in your postmix account will have.
0.001 BTC (plus miner fee)
0.025 BTC (plus miner fee)
0.01 BTC (plus miner fee)
0.70 BTC (plus miner fee)
0.05 BTC (plus miner fee)
3.50 BTC (plus miner fee)
0.50 BTC (plus miner fee)
35.00 BTC (plus miner fee)
Generally the larger the amount you are cycling, the larger the pool you want to choose.
The denomination of the pool determines the minimum amount you can cycle through that pool and the resulting denomination of the newly cycled UTXOs in your wallet. Generally the larger the UTXO you are cycling, the larger the pool you want to choose.
Cycling 0.65 BTC in the 0.01 Pool would create 65 outputs of 0.01 BTC
Cycling 1 BTC in the 0.05 Pool would create 20 outputs of 0.05 BTC
Cycling 1 BTC in the 0.5 Pool would create 2 outputs of 0.5 BTC
Occasionally we will announce promotional SCODE's - or Samourai Discount Codes - that you can apply to your Whirlpool client for reduced price or even free mixes. Keep an eye on our Twitter account and our Telegram rooms to be the first to hear about new SCODE's
Whirlpool is completely non custodial. The term "account" refers to an address space covered by your recovery words and passphrase. Within Whirlpool there are two areas of this address space that are segregated from the rest of the wallet to preserve privacy.
This account consists of all the bech32 UTXOs within your standard Samourai Wallet. UTXOs in this account have not been cycled through Whirlpool yet. You can receive deposits directly into this account or select UTXOs from this account to cycle.
This account consists of all the UTXOs that are prepared to cycle but are still pending. UTXOs will remain in Premix until they have one confirmation and they are selected in a Whirlpool cycle. These UTXOs cannot be spent yet but will have priority in any Whirlpool cycle over UTXOs in the Postmix Account.
This account consists of all the UTXOs that have completed at least one cycle. These UTXOs are available for spending from within Samourai Wallet or available to cycle again for greater privacy.
