From Theory to Implementation: Leveraging Zero-Knowledge Proofs for Secure Blockchain Transactions

Résumé

The blockchain technologies have the potential of being decentralized and secure, yet they suffer major privacy and scalability issues in the public networks. Zero-Knowledge Proofs (ZKPs) is an influential cryptographic scheme that allows one party to demonstrate whether a statement is valid without disclosing the information. In this paper, the authors discuss the concept of integrating ZKPs into blockchain ecosystems to further their privacy in transactions, increase scalability, and enable trustless checks. We look at the theoretical concepts, challenges of implementation, and practical applications and give a framework of the deployment of ZKPs in blockchain systems. The applications of performance evaluation to decentralized finance (DeFi) and identity management and future research directions are presented. The combination of theory and practice helps develop the potential of ZKPs to develop safe and effective blockchain infrastructures [1]-[3] in this work.
