Dr. Sharmila leads research on secure digital asset custody systems at Liminal Custody

The details

• Liminal Custody is developing institutional-grade custody infrastructure for digital assets, focusing on cryptographic security and distributed systems.
• Dr. Sharmila, Principal Scientist and Head of Research & Development at Liminal Custody, leads the development of secure custody systems for digital assets.
• Her work bridges academic cryptography with real-world financial security, applying concepts like multiparty computation and threshold cryptography.
• Digital asset custody must function under a 'zero-trust' model, assuming adversarial conditions and avoiding single points of trust.
• Liminal Custody ensures long-term security through cryptographic agility, allowing systems to upgrade algorithms without dismantling infrastructure.
• The company is preparing for the transition to post-quantum cryptography, which will require rethinking how cryptographic primitives integrate with distributed key management frameworks.
• Real-world deployment of cryptographic protocols involves collaboration between researchers, engineers, and security auditors to ensure resilience.
• Dr. Sharmila emphasizes the importance of increasing representation in cryptography and deep-tech security research, particularly for women.
• Institutional investors are reshaping expectations for custody infrastructure, requiring strong governance frameworks and transparent operational controls.
• Technologies like multiparty computation and threshold signature schemes help institutions enforce transaction approval policies while minimizing single points of failure.

The bigger picture

• Digital asset custody is a critical pillar of the modern financial ecosystem as blockchain technology gains mainstream adoption.
• Traditional key management systems are insufficient in the digital asset ecosystem, requiring advanced cryptographic techniques for security.
• Cryptographic agility ensures custody systems remain secure as technological landscapes evolve over decades.
• The transition to post-quantum cryptography requires long-term preparation and rethinking of cryptographic integration.
• Real-world systems must balance mathematical guarantees with practical considerations like implementation risks and compliance.
