# QRL: The Quantum Resistant Ledger

> For the complete documentation index, see [llms.txt](/llms.txt). This markdown home page gives agents a compact entry point into QRL site content.

The Quantum Resistant Ledger (QRL) is a post-quantum secure blockchain and digital asset platform using XMSS signatures to protect against current and emerging cryptographic threats.

Visionary blockchain and digital asset security.

## 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.

## 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.
