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.
