chore(examples): bump noir-rs to v1.0.0-beta.19#1130
Merged
Conversation
zkmopro/noir-rs#37 migrated off the custom bb/ FFI crate to the official barretenberg-rs crate from crates.io, and bumped the noir-lang deps from v1.0.0-beta.8 to v1.0.0-beta.19. * crates/examples/Cargo.toml: bump noir-rs tag. * basic_zk/noir/Nargo.toml: bump sha256 to v0.3.0 and noir-date to v0.5.6 for nargo v1.0.0-beta.19 compatibility. * basic_zk/noir/src/main.nr: drop deprecated `dep::` import prefix. * basic_zk/noir/target/noir.json: recompile with nargo v1.0.0-beta.19 (ACIR serialization format changed). * basic_zk/verifier.rs: adjust public-input extraction for the new proof layout. noir-rs beta.19 prefixes proof bytes with a 4-byte BE num_public_inputs, so the date and hash offsets now start from proof[4..]. Also validates num_pub == 35. * basic_zk/README.md: update noirup version and simplify bbup invocation.
