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.

Protocol types

• zakura-protocol, including zcash_protocol::encoding from zcash_encoding 0.4.0 (forked from zcash_protocol 0.10.5)
• zakura-address (forked from zcash_address 0.13.0)
• zakura-transparent (forked from zcash_transparent 0.10.0)
• zakura-zcash-script (forked from zcash_script 0.6.0)
• zakura-zip321 (forked from zip321 0.9.0)

Proof of work

• zakura-equihash (forked from equihash 0.3.0)

Transactions and keys

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

Shielded protocols

• zakura-note-encryption (forked from zcash_note_encryption 0.4.2): shared note encryption, trial decryption, and output recovery.

• 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)

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-reddsa-frost: threshold signing for RedJubjub and RedPallas, extracted from zakura-reddsa.
• zakura-redjubjub (forked from )

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

Threshold signing is a separate dependency. Consumers migrating from the zakura-reddsa/frost feature should depend on zakura-reddsa-frost and replace reddsa::frost::redjubjub and reddsa::frost::redpallas imports with reddsa_frost::redjubjub and reddsa_frost::redpallas. Plain RedDSA consumers do not resolve or compile the FROST stack. The Common workspace lockfile still includes it for the dedicated FROST crate.

Experimental arithmetic and proving

• zakura-udon: Pasta field and curve arithmetic and allocation-free FFTs.
• zakura-bento: compile-time arithmetic and checked POD storage and embedding.
• zakura-bento-core and zakura-bento-macros: Bento implementation crates.
• zakura-sensei: proves post-NU6.3 Ironwood Actions, verifies all three Orchard circuit versions, and provides RedPallas signatures.
• zakura-sensei-shared: circuit descriptions and prover record layouts.
• zakura-sensei-artifacts and zakura-sensei-macros: host-side data and code generators.
