Last Month at QRL - June 2022
Highlights Celebrating four years of QRL On June 26th 2018, and after two years of meticulous development followed by several third-party audits, the first enterprise-grade post-quantum secure blockchain using the signature scheme, XMSS, was released to the world, called the Quantum Resistant Ledger (QRL). As visionaries, we had the foresight to use XMSS which is currently a NIST recommendation, along with an extensible address format for crypto-agility. Right out of the gate we launched with a 100% post-quantum secure address space with GUI wallets for Mac, Windows, and Linux and support for tokens, notarisation, and an amazing api and documentation.

Techniques for efficient post-quantum finance (Part 1: digital signatures)
The first part of a series for developing efficient post-quantum finance in an adversarial world. In this article, we look at how to efficiently implement lattice-based digital signature schemes. We show how they can be made more efficient with sparse keys, and link to a python package that employs these signatures.
