The Ashigaru team relaunches the CoinJoin tool to enhance Bitcoin transaction privacy.
The development team behind the Ashigaru wallet has officially revived the Whirlpool CoinJoin solution, once again offering users the ability to improve the privacy of their Bitcoin transactions.
The release of Ashigaru Whirlpool represents a faithful implementation of the original protocol developed by Samourai Wallet. The platform allows users to voluntarily participate in Zerolink CoinJoins, ensuring full privacy for both past and future transactions by breaking deterministic links between inputs and outputs with 100% entropy, according to the announcement. All connections to the Whirlpool coordinator occur exclusively via the Tor network.
The core architecture remains true to the original design created by TDevD, Samourai’s ZeroLeak, and LaurentMT of OXT, while introducing updates developed by the open-source Ashigaru project over the past six months.
One of the key innovations lies in the user interface: Ashigaru Whirlpool introduces Ashigaru-terminal, a Terminal User Interface (TUI) application that marks a clear shift from the previous graphical user interface model.
The new system uses an Electrum server as its backend, removing the dependency on Dojo and making the solution compatible with platforms such as Start9, Umbrel, and myNode. This architectural change also ensures that the Ashigaru team has no access to users’ master public keys (xpubs).
Ashigaru-terminal is available on all major desktop operating systems: Windows, Mac, and Linux. To keep continuous remixing active, users must keep their computers connected and online, properly configuring power settings to prevent automatic sleep modes or wireless disconnections. The Ashigaru Whirlpool code is publicly available for community review and contributions.
Fees
The new implementation introduces adjustments to the fee structure and available pool denominations. Initially, two pools are active:
- 0.025 BTC pool: applies a 5% fee (equivalent to 0.00125 BTC) with a maximum limit of 20 UTXOs per Tx0 transaction. Subsequent remixes remain completely free and unlimited;
- 0.25 BTC pool: follows the same 5% fee structure (0.0125 BTC) with an identical maximum limit of 20 UTXOs per Tx0 transaction.
