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.

QRL Games | Winter Hackathon 2022

events

Introduction We’re excited to announce our upcoming QRL Games - Winter Hackathon 2022. This builds off of the success of our QRL Hackathon 2022 in Amsterdam where we revealed our public devnet with Proof-of-Stake (PoS) and EVM-compatible smart contract functionality. The main theme for this hackathon is, as the name implies, all about games. Whether it’s taking inspiration from a nostalgic game you played growing up or gamifying any aspect of the project that your quantum-resistant heart desires, the options here are endless.

Until the QRL Games - Winter Hackathon 2022!
