Abstract

Adiane Cueto Portuondo, Dariel Gonzalez Robinson and Angel Alejandro Guerra Vilches

This research work focuses on zero-knowledge cryptography and its application in blockchain technology. The theoretical foundations of zero-knowledge cryptography, its practical applications and limitations are addressed, and existing protocols applicable to blockchain are explored. The challenges of Privacy and confidentiality in the context of blockchain are discussed and how this type of cryptography can mitigate those challenges. Several Cryptographic protocols are examined and an example of Implementation through the zkLedger system is presented. Finally, several current challenges in this field are identified, including Computational efficiency, scalability and interoperability. The Studio aims to provide an updated vision of zero- knowledge cryptography applied to the blockchain, and to serve as a starting point for future investigations in this area.
