zRonin

Privacy-Preserving Smart Contract System for QRL Zond

zRonin brings on-chain privacy to the QRL Zond network using zero-knowledge proofs. It enables users to shield tokens, make private transfers, and interact with DeFi protocols anonymously - all while maintaining post-quantum security through Dilithium signatures and zk-STARKs.

Features

• Private Transactions: Shield ZRC-20 tokens and NFTs from public view
• Post-Quantum Security: Dilithium signatures (NIST FIPS 204) + zk-STARKs
• No Trusted Setup: Transparent proof system without ceremony
• DeFi Integration: Private swaps, lending, and dApp interactions via recipes
• Compliance Tools: Viewing keys and proof-of-innocence for regulatory needs

Token: $ZRON

Prerequisites

• Node.js (Claude says 18+)
• Local QRL Zond node (or testnet access, local reduces costs to operation only)
• Rust (for Winterfell compilation, if building provers)

Cryptography

zk-STARKs

• Transparency: No trusted setup required
• Post-Quantum: Secure against quantum computers
• Scalability: Efficient verification on-chain

Dilithium Signatures

• Standard: NIST FIPS 204 (ML-DSA)
• Security Level: 128-bit post-quantum
• Implementation: QRL battle-tested code

Poseidon Hash

• ZK-Friendly: Optimized for arithmetic circuits
• Merkle Trees: 16-level depth, 65,536 capacity

Security

Security Model

• Privacy: Shielded balances are unlinkable
• Post-Quantum: Resistant to quantum attacks
• Transparent: No trusted parties or setup ceremonies

Responsible Disclosure
