BDK v1.0
summary
BDK v1.0 is a ground-up redesign that ships as a modular Rust library with distinct components for wallet, keychain, transaction set and chain backends and a zero-dependency coin module for use across Bitcoin forks and chain sources like Electrum or block files. It implements monotonic CRDT-like data structures so updates are order-independent and introduces transaction anchors tying txids to block locations to produce a consistent history. Prototype works end to end but confirmation tracking has known performance limits being addressed.
