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.

Introducing a powerful post-quantum safe public devnet pre-release with Ethereum Web3 ecosystem compatibility

technical

Anyone is now able to run their own Proof-of-Stake node connected to the public devnet network, stake, and enjoy many of the pleasures of the web3 ecosystem, all while knowing that it was created with longevity and security in mind.

Last Month at QRL - August 2022

technical

The QRL Hackathon 2022 has officially begun, opening the doors for everyone from institutions to individuals to be able to build post-quantum secure web3 applications more through Ethereum compatible smart contracts. Interested? Join the hackathon today.

Until the QRL Hackathon 2022 in-person event. First stage has begun!
