10 years of post-quantum digital asset security · 2016–2026

The Quantum Resistant Ledger

Building the next generation of secure digital assets and decentralized applications.
Explore QRL Discover QRL 2.0
Security by Design
A powerful blockchain platform secured by XMSS
XMSS is a NIST-approved post-quantum secure digital signature scheme
Future Proof
Secure digital assets
The QRL digital asset is secure against current and emerging cryptographic threats. Our suite of solutions provide a range of options for the safe custody of QRL digital assets and interaction with public and private post-quantum secure blockchains built on our core protocol.
Enabling post-quantum secure communications
Combining on-chain lattice key storage with our powerful ephemeral messaging layer to internode communication provides a first-of-its-kind post-quantum secure message layer for ultra-secure digital communications.
Broad integrations & diverse ecosystem
Tight integration with the world's leading hardware digital asset storage solutions and open development architecture, open-source and audited cryptography and a rich API experience for developers make QRL a robust enterprise-grade solution.
An externally audited enterprise-grade blockchain platform secure today from the quantum computing advances of tomorrow.
  • Visionary Security
    QRL is the first industrial implementation to utilize IETF specified XMSS; a hash-based, forward secure signature scheme with minimal security assumptions and reusable addresses.

10 years of post-quantum digital asset security

events

From the first code in 2016 to a mainnet built on XMSS and the development of QRL 2.0, a decade of QRL has been guided by one commitment: digital assets should remain secure as computing advances. We look back at the foundations and ahead to post-quantum smart contracts, proof of stake, and the next generation of builders.

Can AI Break ECDSA or ML-DSA? Exponential Is Still Exponential

technical

AI is making cryptographic attacks faster, but can it break ECDSA or ML-DSA? Dr. Joseph Kearney examine’s what recent results actually show, why faster exponential attacks remain exponential, and where the more immediate risks are, from weak implementations to quantum computers running known algorithms.
