Entry: Zero-Knowledge Proof: Elgar Encyclopedia of Cryptocurrencies, Blockchain and DLT

The balance between transparency in blockchain technology and the need for confidentiality raises significant challenges for system design. A combination of technologies—such as zero-knowledge proofs (ZKP) and blockchain—provides capabilities that strengthen future digital transformation against malicious actors and the increasing threats toward sensitive information leakage. ZKP has become an increasingly valuable component within blockchain systems to enhance privacy, scalability, and security, ensuring that transaction data and execution cannot be forged or deleted by malicious actors within or across systems. However, applying and creating ZKP claims is still computationally heavy and technically challenging to implement and may not yet be suitable for all use cases.
