digital asset storage.

ColdShield®, Paribu Custody's proprietary security framework, is built on the latest practical advancements in cryptography. By combining HSM, Secure Enclave, and MPC technologies within a cohesive architecture, it provides the core security layer of the Paribu Custody platform.

Learn more about its scientific foundations and how it works.

MPC

Private key management, distributed.

Paribu Custody adopts global standards in private key management.

Its multi-party computation protocol is based on the work Fast Multiparty Threshold ECDSA with Fast Trustless Setup by Rosario Gennaro and Steven Goldfeder of the City University of New York, and makes the entire process fully distributed.

Dealerless key generation

Participants collaborate to generate the key shards without needing to trust a single party.

No single point of failure

By eliminating the dealer, the system becomes more robust against attacks, as there is no central authority that could be compromised.

Distributed processes

No single participant has enough information to reconstruct the entire key on their own.

TechnologyHow it works?The three building blocks of the

ColdShield®architecture

Absolute custody, constantly.

Powered by advanced cryptography, the proprietary technology ColdShield® is engineered with every security aspect in mind. Perfection in digital asset security with unparalleled protection.

ColdShield® provides a layered approach to private key protection and is engineered with all risks in mind, from key safeguarding to transaction execution. It is designed to meet regulatory expectations, deliver robust security controls, and offer unique backup capabilities at every layer of the architecture.

HSM

Hardware security modules

Assets are protected with HSM against unauthorized access and tampering.

Secure Enclave

Trusted execution environment

Secure Enclave protects the integrity of the data and computations.

MPC

Multi-party computation

MPC distributes key operations across independent parties, eliminating single points of failure.
