Wasabi Wallet v2.6.0: First Version to Sync & Operate Without a Central Server

• Wasabi Wallet v2.6.0 "Prometheus" is a major update for the project, focused on resilience and independence from centralized systems.
• Key features include support for BIP 158 block filters for direct node synchronization, a revamped full node integration for easier setup without third-party reliance, SLIP 39 share backups for flexible wallet recovery (sponsored by Trezor), and a Nostr-based update manager for censorship-resistant updates.
• Additional improvements include UI bug fixes, a new fallback for transaction broadcasting, updated code signing, stricter JSON serialization, and options to avoid third-party rate providers, alongside various under-the-hood enhancements.

This new version brings us closer to our ultimate goal: ensuring Wasabi is future-proof," said the developers, while also highlighting the following key areas of focus for the project:

• Ensuring users can always fully and securely use their client.
• Making contribution and forks easy through a codebase of the highest quality possible: understandable, maintainable, and improvable.

"As we achieve our survival goals, expect more cutting-edge improvements in Bitcoin privacy and self-custody. Thank you for the trust you place in us by using Wasabi," was stated in the release notes.

What's new

• Support for Standard BIP 158 Block Filters. Wasabi now syncs using BIP 158 filters without a backend/indexer, connecting directly to a user's node. This boosts sync speed, resilience, and allows full sovereignty without specific server dependency.
• Full Node Integration Rework. The old integration has been replaced with a simpler, more adaptable system. It’s not tied to a specific Bitcoin node fork, doesn’t need the node on the same machine as Wasabi, and requires no changes to the node’s setup.
  • "Simply enable the RPC server on your node and point Wasabi to it," said the developers. This ensures all Bitcoin network activities—like retrieving blocks, fee estimations, block filters, and transaction broadcasting—go through your own node, avoiding reliance on third parties.
• Create & Recover SLIP 39 Shares. Users now create and recover wallets with multiple share backups using SLIP 39 standard.

"Special thanks to Trezor (SatoshiLabs) for sponsoring this amazing feature."

• Nostr Update Manager. This version implements a pioneering system with the Nostr protocol for update information and downloads, replacing reliance on GitHub. This enhances the project's resilience, ensuring updates even if GitHub is unavailable, while still verifying updates with the project's secure certificate.
• Updated Avalonia to v11.2.7, fixes for UI bugs (including restoring Minimize on macOS Sequoia).
• Added a configurable third-party fallback for broadcasting transactions if other methods fail.
• Replaced Windows Code Signing Certificate with Azure Trusted Signing.
• Many bug fixes, improved codebase, and enhanced CI pipeline.
• Added the option to avoid using any third-party Exchange Rate and Fee Rate providers (Wasabi can work without them).
• Rebuilt all JSON Serialization mechanisms avoiding default .NET converters. Serialization is now stricter.
