0.6.9-420

The final frontier is here for the 0.6.x release line, v0.6.9-420. Nice!

This one has a great new feature for Android, Lightning Box.

Lightning Box is a Lightning Address provider for mobile nodes like Blixt Wallet, letting you receive Lightning Address payments directly to your phone.
This works in conjunction with the Persistent Mode released in v0.6.9, which allows Blixt Wallet to stay active in the background in order to receive payments.
You can also use this for nostr tipping.

Register your own Lightning Address from the left menu -> Advanced -> Lightning Box.
Lightning Box is open-source software and you can run your own instance, working seamlessly with Blixt Wallet.
A draft specification for the protocol can be found here: https://github.com/hsjoberg/blips/blob/lnurl-forwarding/blip-lnurlforward.md.
The Blixt Project hosts a Lightning Box service for @blixtwallet.com Lightning Addresses.

In the future we will look at Lightning Box support without using Persistent mode and for other platforms than Android.

Important note: If battery drain for Persistent Mode is high, try "Compact lnd's databases" from Settings -> Debug.

Changelog

Common

• Updated to lnd 0.17.1
• Speedloader ("LN channel sync") has been improved with support for bsdiff patches
  This means you won't have to download the full channel database for each sync, resulting in speedier syncs
• Zero-confirmation channels is now supported on Dunder LSP!
• Added support Simple Taproot Channels for manual channel openings
  Simple Taproot Channels will be enabled for Dunder LSP too in the near future
• Chain filter syncing should be substantially faster, as a part of Neutrino performance improvements in lnd 0.17.0

• New languages!
  We have support for 12 new languages: Czech, Danish, Finnish, Hindi, Korean, Norwegian, Persian, Romanian, Traditional Chinese, Simplified Chinese, Swahili and Kenyan Swahili.
• Changed the camera lib to react-native-vision-camera. This camera lib should be more performant and offers faster QR code scanning
• Receiving onchain via Taproot is enabled by default and the setting for it has been removed.
  Long-press on the "Generate address" button to generate a SegWit address
• Upgraded react-native to version 0.72.6. This has resulted in faster startup times

Android

• New Tor implementation!

  This also lets you always keep in sync with the Bitcoin chain, making spontaneous payments really quick.
  In the near future, we will allow Lightning Address support for any user running Persistent Mode, via the service Lightning Box.
  Note: This may affect your battery life depending on the device. Experiment with this new feature and let us know your experience.
• We now explicitly only build for arm64-v8a. This has resulted in slightly smaller APK sizes

0.6.8

Blixt Wallet v0.6.8 is here and we have an important new feature called Speedloader!

Speedloader syncs the wallet's channel database ("channel graph") on startup. This is important for payment pathfinding and will make sure you have an up-to-date database.

In previous versions of Blixt Wallet, the channel database would only sync with Lightning peers when the app is active (or when the background sync job runs on Android). This can be problematic as it may lead to missed channel updates, which in turn can result in more errors in pathfinding.

Opt in to this new feature by enabling it in the settings under the Experimental category.

Changelog

Common

• Added the ability to periodically sync Lightning channels (via Speedloader). Find the setting in the Experiments category.
• Added basic hodl invoice support.
  Payments now show up as "pending" in the transaction log before they are settled or cleared out.
• Added 0-conf channel support.
  Add pubkeys for nodes from which you would like to accept 0-conf channels. In the future, Dunder LSP may support 0-conf channels.
• Added the ability to compact lnd's databases.
• Fixed restore via channel backup file not working correctly
• Added Toast notification and Debug Log screens
• Updated lnd to 0.16.4

Android

• Fixed push notifications not working

iOS

• Fixed a long-standing crash issue affecting some iPhone devices.
  The known devices are 5/5s/6/6s/7/X/XR.
  If you have experienced problems with Blixt Wallet crashing in the past, please try Blixt Wallet again with a fresh 0.6.8 instance.

v0.6.2

• The app has been translated to Croatian!
• Updated lnd to v0.15.5
• Lnd's strict graph db channel pruning config is now disabled by default.
  Strict graph pruning is a feature that more aggressively prunes channels that are deemed unusable from lnd's channel database. This database is used for payment pathfinding among other things.
  We've found that this strict pruning is causing routing failures to several lightning nodes within the network, because the algorithm pruned too many channels, so we're choosing to disable this feature. This will lead to a slightly higher memory footprint for the app.
  Note: in order to restore the channels that got pruned, you need to either restore a wallet or create a new wallet from scratch running Blixt Wallet 0.6.2
• It's now possible to see the payment duration for an invoice paid using Blixt. Tap a transaction in the transaction log to view
• Added "Show Network Info" to the Lightning Network category in Settings. This modal lets you see information about the Lightning Network
• Fixed a bug where the camera button did not work in Keysend Experiment
• Fixed a bug where the channel reserve was not subtracted from the remote balance in Lightning Channels
