  • Announced LDK Node, a ready-to-go Lightning node library. "Check out @_tnull’s blog post and spattering of workshop appearances about LDK Node, like this one from Bitcoin++ in April. Then see @ConorOkus and Elias’ appearance on the Bitcoin Developers Channel where they discussed the whats and whys of it."
  • "There have been two LDK releases since the last newsletter, 0.0.115 in April and 0.0.116 in July. The latest release includes full (beta) support for Lightning anchor channels."
  • "The Bitcoin Development Kit formed a foundation to promote the development of and public access to BDK."
The BDK v1.0 alpha "is nearly ready. It introduces ChainOracle and related refactoring, making it possible for BDK 1.0-based wallets to directly access blockchain data from sources such as Compact Block Filter clients and the Bitcoin Core RPC interface (coming soon)."
  • "In other BDK news, the [upcoming] 0.29.0 BDK language bindings release includes support for Windows on Kotlin/JVM, new Python targets, exposed Wallet.is_mine(), and Script.to_bytes() methods. Bdk-flutter and bdk-rn also recently released new versions."
