zakura-core/common

This repository contains the Zakura Common libraries: the foundational Rust crates used in Zakura and made available for the Zcash ecosystem. Use this stack in your wallets or in other tools for better performance.

Transactions and keys

• zakura-primitives (forked from zcash_primitives 0.30.0)
• zakura-keys (forked from zcash_keys 0.16.1)

Shielded protocols

• zakura-orchard (forked from orchard 0.15.5)
• zakura-sapling-crypto (forked from sapling-crypto 0.7.0)
• zakura-proofs (forked from zcash_proofs 0.30.0)

The halo2 proving system

• zakura-halo2-proofs (forked from halo2_proofs 0.3.5)
• zakura-halo2-gadgets (forked from halo2_gadgets 0.5.0)
• zakura-halo2-poseidon (forked from halo2_poseidon 0.1.0)
• zakura-halo2-legacy-pdqsort (forked from halo2_legacy_pdqsort 0.1.0)

Curves, hashes, and signatures

• zakura-pairing (forked from pairing 0.23.0)
• zakura-bls12-381 (forked from bls12_381 0.8.0)
• zakura-jubjub (forked from jubjub 0.10.0)
• zakura-bellman (forked from bellman 0.14.0)
• zakura-pasta-curves (forked from pasta_curves 0.5.2)
• zakura-sinsemilla (forked from sinsemilla 0.1.0)
• zakura-reddsa (forked from reddsa 0.5.2)
• zakura-redjubjub (forked from redjubjub 0.8.0)

zakura-redjubjub is a thin wrapper over zakura-reddsa, so the two are maintained together.

Rust toolchain

rust-toolchain.toml pins the development toolchain to Rust 1.97.1, so cargo in a checkout (builds, Clippy, rustfmt, and the benchmarks in crates/orchard/benches) uses the same compiler for everyone. The crates themselves keep a minimum supported Rust version of 1.91 (rust-version in Cargo.toml), which CI builds separately; raising the MSRV is a consumer-visible change, while bumping the development pin is not. The workspace uses Cargo's MSRV-aware resolver, so cargo update prefers dependency releases that the 1.91 toolchain can build. To reproduce the MSRV check locally:

rustup toolchain install 1.91.0 --profile minimal
cargo +1.91.0 check --locked --workspace
