This upgrades bitcoin to 0.32 and related dependencies accordingly. Note that the bdk_electrum crate has not been upgraded to the most recent version available as the Electrum syncing there takes much longer due to the fetching and validation of Merkle proofs. There are ongoing BDK changes in relation to that and so we can further upgrade this dependency once those changes have been completed. Non-BDK changes to the liana and lianad crates are taken from darosior's commit 20ee8b1e7b77cbf65942bc4f083afea95f2d1506 in draft PR https://github.com/wizardsardine/liana/pull/1228.
Liana fuzzing targets
This folder hosts the fuzz targets for Liana. We simply use
cargo-fuzz for now (see there for instructions on how
to run the targets).
