Доказательство с нулевым разглашением (ZKP)
Метод доказательства знания без раскрытия самой информации.
Важно для приватности и масштабирования (Zk-Rollups). Позволяет проверять транзакции без раскрытия сумм или адресов. Zk-SNARKs и zk-STARKs — популярные реализации.

🤓 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.
