영지식 증명 (Zero-Knowledge Proof)
비밀을 밝히지 않고 증명하기.
블록체인의 개인 정보 보호 및 확장성(Zk-Rollups)에 필수적입니다. 금액을 공개하지 않고 거래를 증명할 수 있습니다. zk-SNARKs 및 zk-STARKs가 일반적입니다.

🤓 Expert Deep Dive
Zero-Knowledge Proofs (ZKPs) leverage advanced cryptography, such as zk-SNARKs (Succinct Non-Interactive Arguments of Knowledge) or zk-STARKs (Scalable Transparent Arguments of Knowledge), to enable a Prover to convince a Verifier of a statement's truth without revealing the underlying data. In the context of blockchain, this is critical for both privacy (e.g., Zcash) and scalability (e.g., ZK-Rollups). The 'Succinct' nature of SNARKs allows for very small proof sizes that are fast to verify, shifting the heavy computational burden off-chain while maintaining on-chain security. STARKs improve on this by eliminating the need for a 'trusted setup' and being quantum-resistant, though at the cost of larger proof sizes.
