## Post Quantum Cryptography

Post quantum cryptography refers to new cryptographic algorithms that are intended to be secure against both quantum and classical computers. These algorithms are based on mathematical problems that are currently thought to be difficult even for quantum machines, such as lattice-based, code-based, or multivariate polynomial problems.

As the development of quantum computers accelerates, the migration to these new standards becomes essential for protecting the global financial system. The transition is complex because it requires updating the software and hardware infrastructure of decentralized protocols without compromising current security.

This involves rigorous standardization processes and extensive testing to ensure no new vulnerabilities are introduced. For digital assets, post-quantum readiness is a prerequisite for long-term institutional adoption.

It is a fundamental shift in how we secure data and value in an increasingly advanced technological landscape.
