TSUNAGI Project

Independent Cardano node implementation in Zig

TSUNAGI is a deterministic Cardano node built independently from scratch. No Haskell dependency. No IOG codebase fork. Pure Zig implementation covering networking, consensus, ledger, and operator tooling.

Architecture

Networking

Node-to-node mux, ChainSync, BlockFetch, TxSubmission. Interoperable with cardano-node v14+.

Consensus

Praos leadership evaluation, VRF/KES verification, slot observatory, shadow producer, candidate validator.

Ledger

Deterministic UTxO engine with apply/rollback symmetry. CBOR block decode, tx parsing, delta tracking.

Operator

Health scoring, telemetry dashboard, mempool observatory, confirmation tracking, producer dry-run.

Milestones

ChainSync follower (mainnet, preview, sancho)

Deterministic block decode + UTxO tracking

Operator dashboard + health engine

Mempool + tx submission + confirmation tracking

Producer readiness + shadow producer + candidate validation

Forge: real VRF proof + KES signature on preview

ChainSync interop with real cardano-node relay

BlockFetch + relay block acceptance

Historical chain coverage + light node mode

Cross-chain integration path
