This release now uses the updated algorithm from the new Curve Trees/Forest paper ("delta") - see https://eprint.iacr.org/2024/1647 - which makes the code significantly simpler. There is also a substantial speedup in setup time and proving time. For example: a 400K keyset now only needs about 30s for one-time setup, and only 1-2 seconds to create a proof.
Compilation by using cargo test then cargo build --release is strongly recommended, as opposed to downloading the below assets, to reduce trust requirements when using binaries.
