Wasabi Wallet now uses the newest version of Bitcoin Knots (v0.21.1) on its backend after previously using a patched version due to a mempool issue where files over 32mb could not be serialized.

Significant changes to Bitcoin Knots:

  • Mainnet and testnet activation parameters for the taproot soft fork (BIP341) have been included in this release; these also add support for Schnorr signatures (BIP340) and Tapscript (BIP342).

Taproot will be activated at block 709632, expected in early or mid November. When activated, these improvements will allow users of single-signature scripts, multisignature scripts and complex contracts to all use identical-appearing commitments that enhance their privacy and the fungibility of all bitcoins. Spenders will enjoy lower fees and the ability to resolve many multisig scripts and complex contracts with the same efficiency, low fees and large anonymity set as single-sig users. Taproot and Schnorr also include efficiency improvements for full nodes such as the ability to batch signature verification. Together, the improvements lay the groundwork for future potential upgrades that may improve efficiency, privacy and fungibility further.” ~ 0.21.1 Release Notes

Wasabi Wallet does not utilize the Taproot related features.
