We've released bark-0.1.0-beta.6 featuring hArk (Hash-lock Ark), a major protocol evolution that eliminates synchronous interactivity during rounds. Previously, all round participants had to be online simultaneously to sign intermediate transactions. hArk removes this requirement—the server generates a unique secret for each VTXO, and participants can claim asynchronously after signing a forfeit transaction. This also enables efficient consolidation of multiple VTXOs into a single output and reduces server costs during malicious exit scenarios. Note: Wallets created before this release require migration due to security upgrades with hardened key derivations. Create a new wallet and transfer funds before upgrading.

The Ark model of Lightning: Users hold "funds at rest" in VTXOs, then swap into Lightning channels via HTLCs to make payments.

Latest changelog for bark 0.1.0-beta.3 to beta.5 is out! The biggest addition is barkd—a wallet daemon with RESTful API for node runners and businesses wanting simple automation. We've also made ark-lib WASM-compatible for web environments, replaced the arkoor-depth limitation with checkpoints, and improved Lightning payment reliability.
