This repo documents the idea, constraints, and minimum components to explore a Starknet-like rollup that settles to Zcash L1 via a Transparent Zcash Extension (TZE) that verifies Circle STARK proofs. What is Ztarknet 🛡️🐺? Ztarknet 🛡️🐺 proposes a Starknet-style L2 that executes Cairo programs, proves the resulting state transitions with Circle STARKs (Stwo), and settles those transitions on Zcash L1 by having full nodes verify the proof natively via a TZE verifier. It reuses an existing Starknet client (e.g., Madara ) for sequencing/execution and a Stwo/Cairo prover for proofs. The L1 verification surface is a single TZE type defined by a draft ZIP. Why Zcash? Zcash already offers strong base-layer privacy. Ztarknet explores programmability and scale via an L2—with validity proofs checked natively on Zcash using the TZE framework (ZIP-222) and the associated digest changes (ZIP-245/244). Rationale - Separation of concerns: keep Zcash L1 minimal, push general execution to an L2 VM (Cairo), and anchor L2 with succinct validity proofs. - Clean L1 integration: use a TZE rather than Script changes; TZEs were designed to add new transparent validity conditions in a well-bounded way. - Rust-native path: Madara (Rust) and Stwo/Cairo (Rust verifier + CLI) keep the prototype within Zebra’s Rust ","default_branch":null,"files":null,"tree":[],"storefront":"/r/Ztarknet","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/Ztarknet/ztarknet/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
