Zcash Layer (Z-Shield Pool)
⛓️ Zcash Layer (Z-Shield Pool)
The Zcash Layer acts as the privacy-preserving collateral pool for ZkStable. This layer ensures that collateral backing $pUSD remains confidential while still verifiably existing.
🧱 Components
Shielded ZEC Pool
Holds user-deposited collateral using Zcash shielded addresses.
Deposit/Withdraw Circuits
Validates proof of asset ownership without revealing balances.
ZK-SNARK Commitment Trees
Stores hashed balances for proof verification.
🔐 How Privacy is Preserved
Collateral is held in shielded Z-addresses, not transparent public wallets.
Balance proofs are generated as zero-knowledge commitments.
The protocol never exposes wallet identities, deposit amounts, or transaction history.
💼 Role in $pUSD Minting
Users deposit ZEC → ZkStable generates a proof-of-reserve → $pUSD is minted.
No centralized custodian. No visible collateral trace.
🔍 Transparency Without Exposure
All collateral is provable, but never publicly revealed.
