Advanced Cryptography for Blockchains

Principal Investigator: Prof. Sanjam Garg – University of California, Berkeley

Duration: 1 year

‍

Project Overview

This project advances the frontier of blockchain security through the development of next-generation cryptographic tools. Building upon Prof. Garg's seminal work on threshold signatures and privacy-preserving computation, the research will develop new post-quantum-secure cryptographic protocols that enhance privacy, resilience, and interoperability within distributed ledger systems. The work addresses critical challenges in securing blockchain infrastructures against both current and emerging threats, particularly those posed by quantum computing capabilities.

‍

Objectives

The research aims to develop threshold-signature and key-management frameworks that ensure secure, multi-party access to digital assets whilst maintaining robust security guarantees. It will design privacy-preserving mechanisms that balance the competing demands of transparency and regulatory compliance for blockchain transactions. Additionally, the project will investigate cryptographic schemes that demonstrate resilience against quantum adversaries whilst remaining computationally efficient for deployment in real-world blockchain environments.

‍

Ecosystem Development

This project strengthens the blockchain ecosystem by addressing fundamental security challenges that currently limit broader adoption. The development of post-quantum-secure protocols will future-proof blockchain infrastructures against emerging quantum threats, whilst enhanced threshold-signature frameworks will enable more sophisticated multi-party governance and custody solutions. The privacy-preserving mechanisms will help reconcile blockchain transparency with regulatory compliance requirements, creating pathways for adoption in regulated industries.

‍

Expected Outcomes

The project will deliver new cryptographic models and implementations specifically tailored for blockchain infrastructures, contributing both theoretical advances and practical tools that support long-term network security. The findings will be disseminated through peer-reviewed academic publications and made available as open-access resources for the broader blockchain research community, facilitating further innovation and adoption.
