# Explore QRL > For the complete documentation index, see [llms.txt](/llms.txt). This markdown page mirrors [the canonical HTML page](/explore/). The Quantum Resistant Ledger. Building the next generation of secure digital assets and decentralized applications. 10 years of post-quantum digital asset security · 2016–2026. [Discover QRL 2.0](/zond/). ## Security by Design A powerful blockchain platform secured by XMSS. XMSS is a [NIST-approved](https://csrc.nist.gov/publications/detail/sp/800-208/final) 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. ## Platform Features 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. ### Developer Friendly Extensive tools, documentation and a rich API gives the tools to build anything, today, on an industrial grade platform that will survive tomorrow. ### User Oriented A full suite of end-user products designed with the end user in mind: from integrations with hardware wallets to mobile applications. ## For users - [Download Wallets](/downloads/wallets/): Desktop wallets for Windows, macOS, and Linux, with Ledger Nano X/S+ support. - Mobile Wallet: Android and iOS applications developed by third-party provider Volt Development.

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. - [QRL Backs University of Manchester Cryptographers to Strengthen Post-Quantum Signature Infrastructure](https://www.theqrl.org/press/qrl-backs-university-of-manchester-cryptographers-to-strengthen-post-quantum-signature-infrastructure.md): 2026-10-15. Grant supports Dr Bernardo Magri, Dr Tako B. Fouotsa and Dr Trey Li, investigating isogeny-based cryptography, blockchain and post-quantum hardness assumptions - [Can AI Break ECDSA or ML-DSA? Exponential Is Still Exponential](https://www.theqrl.org/blog/can-ai-break-ecdsa-or-mldsa.md): 2026-10-14. 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. ## Follow us - [Telegram](https://t.me/QRLedgerOfficial) - [YouTube](https://www.youtube.com/c/QRLedger) - [X](https://twitter.com/qrledger) - [LinkedIn](https://www.linkedin.com/company/the-quantum-resistant-ledger/) - [Facebook](https://www.facebook.com/theqrl/) - [Reddit](https://www.reddit.com/r/qrl) - [Discord](https://theqrl.org/discord) - [GitHub](https://github.com/theQRL/)
