Release Summary

Turbosync Drastically Reduces Wallet Load Times

This release optimizes the filter checking process to reduce wallet loading times by 90% thanks to code cleanup and a clever key prioritization process dubbed “Turbosync”. With Turbosync, internal addresses that have already been used are not checked for coins in new blocks until after unused addresses have been checked first.

Don’t Float in the Mempool

Incoming funds can now be confirmed faster with Child Pays For Parent (CPFP) to self-spend an unconfirmed UTXO, and outgoing transactions can use Replace By Fee (RBF) to increase confirmation priority or cancel the payment entirely. You don't have to worry about the details, it just works magically under the hood.

Privacy Warnings and Spending Suggestion

New Privacy Warnings present users with one click fixes if they are attempting to construct a transaction that spends nonprivate funds or creates change. Notifications are provided when consolidating more than 10 UTXOs or spending unconfirmed funds, allowing users to avoid potential mistakes without restricting intentional usage.

More Privacy, Less Blockspace

The amount decomposer was refined to make the most effective use of scarce block space so that whales who set a high anonymity score target now need fewer coinjoin rounds to reach 100% privacy. The amount of outputs a client can create in a round has been increased from 8 to 10, and decompositions that produce change outputs are now rarely chosen. Adjustments to the anonymity score calculator and default settings additionally reduce the amount of coinjoining required before all coins are considered private. The anonymity score target of the “Maximize Privacy” coinjoin strategy setting was reduced from a random value between 50-100 to a less conservative range of 27-76, which brings the behavior closer in line with the two efficiency based strategies.

A specter is haunting this world

Wasabi now has a daemon! More experienced users can directly interact with core features of the wallet through an RPC (Remote Procedure Call) interface making it easy for developers to customize their experience and build features that are not available in the GUI version. This release bundles the Daemon, an executable called ‘wassabeed’ that runs the wallet without the graphical interface. The wallet can be run in the background by using the RPC interface, or the Wasabi command line interface allowing users to coinjoin, see their balance, and perform every other function of the wallet without the resource consumption of the graphical interface.

Penguins love black and white

Wasabi can now scan QR codes on Linux computers. This makes importing an address from a phone a lot more private, easier and faster. This feature is now available for Linux and Windows, but not yet for macOS.

Database migration to SQLite

Wallet loading speed improved even more by storing the filters in an SQLite database instead of a plaintext file, reducing disk space requirements by about 1 GB and increasing resilience against file corruption.

Fighting Entropy

Included are several updates to dependencies (HWI, Tor, Avalonia) and a lot of the usual bug squashing and UI polishing.
