I asked my robot.
Blinded Signatures: Ark utilizes blinded signatures during transaction coordination. The server signs your transaction request without actually seeing the specific details of the destination or the output.
Continuous, Rapid CoinJoins: Every single payment on Ark is bundled into a collaborative pool transaction—essentially an off-chain CoinJoin—that settles roughly every 5 seconds. Because many users are lumped into the same pool transaction simultaneously, the ASP cannot determine which incoming fund belongs to which outgoing fund.
Unlinkable P2P Payments: By severing the direct cryptographic link between the sender and receiver, the ASP is entirely blocked from building a behavioral graph or history of your payments.
Standardized vTXO Values: To prevent the server from tracking you using unique transaction amounts, virtual UTXOs (vTXOs) are restricted to standardized tier values (similar to physical cash bills). This stops the server from mapping a specific $14.32 payment from a sender to a receiver.
