Project Eleven is launching Strongpoint MPC, a new approach to multi-party computation that delivers signing performance exceeding that of classical ECDSA-based MPC, the company says. Multi-party computation is already a foundational technology underpinning institutional custody solutions for exchanges, custodians and financial institutions. Project Eleven’s research demonstrates that institutions do not have to sacrifice performance when migrating to post-quantum cryptography; in fact, the company’s approach can improve upon existing systems. “The migration to post-quantum cryptography is underway,” and Strongpoint MPC is available within Project Eleven’s Strongpoint custody platform.
Strongpoint MPC Addresses Post-Quantum Challenges for Digital Assets
Strongpoint MPC delivers signing performance that surpasses existing classical ECDSA-based MPC, a result that challenges expectations surrounding the typical performance trade-offs inherent in post-quantum cryptography. Project Eleven’s research indicates that institutions can adopt post-quantum security measures without compromising the operational efficiency they have established with current MPC technologies. This achievement stems from a novel approach to threshold cryptography, designed to overcome the performance bottlenecks historically associated with hash-based signatures in multi-party computation environments.
Stablecoin issuers, blockchain validators, and cross-chain bridges depend on this distributed signing infrastructure to protect critical operations, and all will eventually need to adapt to post-quantum cryptography. Strongpoint MPC is designed to support multiple signature schemes, accommodating the diverse cryptographic standards and blockchain requirements that will emerge as the industry transitions. The core challenge lies in the mathematical properties of post-quantum signature schemes, which do not directly translate to the efficient threshold signing methods used with ECDSA.
Previous attempts to implement MPC with certain hash-based constructions faced significant latency issues, potentially rendering the technology impractical for institutions processing transactions continuously. Project Eleven’s work addresses this issue, demonstrating that high-performance, post-quantum MPC is achievable without sacrificing flexibility or security, according to the company. This integration is significant because it allows institutions to use post-quantum threshold signing while retaining complete control over their assets and cryptographic key material.
The company reports that its approach avoids the previously assumed performance sacrifices associated with moving to post-quantum MPC. “For years, the industry has operated under the assumption that moving to post-quantum MPC would require meaningful sacrifices in performance and operational flexibility,” the company states, adding that their breakthrough demonstrates this is not necessarily the case. This development is an important step toward making the post-quantum transition practical for the digital asset ecosystem and a key advancement for institutions prioritizing long-term security.
Flexible Architecture Supports Institutional Digital Asset Custody
Strongpoint MPC addresses a critical need for adaptable cryptographic infrastructure, supporting varied signing environments across institutions like custodians, blockchain validators and stablecoin issuers. Unlike a one-size-fits-all approach, the system is designed to accommodate differing security policies and operational requirements, a feature important for widespread adoption. The system’s efficiency extends beyond configuration options to communication protocols, minimizing overhead during signing processes across distributed infrastructure. This focus on streamlined communication is vital because earlier attempts to implement multi-party computation with certain hash-based constructions encountered significant latency issues.
Strongpoint MPC also prioritizes signature indistinguishability, ensuring that signatures produced through the threshold process appear identical to ordinary signatures, concealing the configuration and participating signers. This design choice protects institutional security by preventing the exposure of sensitive information through the signatures themselves.
This performance gain is not merely theoretical. Strongpoint MPC is integrated directly within Strongpoint, Project Eleven’s existing institutional digital asset custody platform, providing a fully deployed solution for institutions seeking to upgrade their security. The platform’s institutional control features further empower organizations to maintain complete oversight of their signing infrastructure and cryptographic key material, a key requirement for regulated financial entities.
