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).
