Ztarknet: Zcash × Starknet: Privacy stays, scale arrives. Let me breakdown the idea in simple terms 👇

1/ Zcash already nailed privacy. What it lacks is cheap scale and programmability. The fix doesn’t require touching shielded pools, just adding a built-in verifier for proofs. One relatively small change could unlock a Starknet-style Layer 2 on Zcash.

2/ Think of it like this: Zcash stays the private base layer. We add a single “proof-checker” that says true/false on a STARK proof. A Starknet L2 then handles fast, programmable transactions, posting proofs back to Zcash for validation.

3/ No new scripting language. No change to the privacy core. No new trust assumptions. Just a clean, bounded verifier that fits naturally in Zcash’s Transparent Extension (TZE) framework.

4/ Why STARKs? They’re hash-based, transparent (no trusted setup), and quantum resitant. They already secure billions in volume on Starknet and other systems. Verification is fast and deterministic, perfect for consensus code.

5/ How it works in practice: The L2 batches transactions, updates a state root, and proves it. It posts “old root, new root, proof” to Zcash. Zcash full nodes verify the proof via the new TZE. If true → anchor accepted.

6/ This approach keeps ZEC supply enforcement fully intact. The verifier never mints coins. It only says whether a proof is valid. ZEC accounting stays in the existing, audited and battle tested consensus code.

7/ Why it matters: ZEC becomes not just a private store of value, but a programmable one. All new utility, DeFi, advanced payments and other apps lives at L2. Settlement and custody stay on Zcash. Fees and gas still paid in ZEC.

8/ Privacy remains the foundation. Scaling and innovation move above it. Zcash stays the safe, encrypted base layer; Starknet brings speed, programmability, and reach. Minimal change. Massive potential. That's it (for now).
