Zero-Knowledge Proofs (ZKPs) are a key technology for privacy protection in blockchain.

What Are Zero-Knowledge Proofs?​

Zero-Knowledge Proofs allow one party (the prover) to prove to another party (the verifier) that a statement is true, without revealing any additional information.

Application Scenarios​

1. Private Transactions​

Verify transaction validity without disclosing transaction details.

2. Identity Authentication​

Prove identity without revealing specific information.

Key Technologies​

zk-SNARKs​

  • Succinct proofs.
  • Fast verification.
  • Requires a trusted setup.

zk-STARKs​

  • No trusted setup required.
  • Quantum-resistant.
  • Larger proof size.

Real-World Projects​

  • Zcash: Privacy-focused cryptocurrency.
  • zkSync: Layer 2 scaling solution.
  • Polygon zkEVM: EVM-compatible ZK Rollup.

Learning Resources​

  • ZK Whiteboard Sessions
  • ZK Hack
  • 0xPARC Courses

Conclusion​

Zero-Knowledge Proofs represent a crucial direction for blockchain technology development and are worth deep exploration.
