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.

Visionary Security

Secure now and from attacks using quantum-computers in the future.

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 that comes with NIST approval

An extensible address format with quantum security built in from the genesis block.

An open source, code-base with implementation verified by third-party audits fromred4sec and x41 D-sec.

Development of enQlave, bringing QRL technology to the Ethereum platform

Developer Friendly
Extensive documentation and an API reference gives the tools to build anything, today, on an industrial grade platform that will survive tomorrow.
Some features already available:

Ledger-wide post-quantum (PQ) security

Reusable addresses

Quantum resistant token (QRT) support

On-chain message support (80 bytes)

PQ document notarisation

Keybase ID integration

Full-featured API

Multisignature wallet capability

Features under development:

PQ proof-of-stake consensus

Easy to secure smart-contracts

Ephemeral messaging ultilising Dilithium and Kyber

Expanding QRL technology to secure other digital assets

User Oriented

A full suite of user-facing applications make interacting with the QRL blockchain and digital assets a breeze.

Our downloads page has products for Desktop (Windows, Mac, Linux), Mobile (iOS, Android) and the web
