Quantum Resistant Ledger

Techniques for efficient post-quantum finance (Part 2: signature aggregation) Geometry Labs in partnership with the Quantum Resistant Ledger ($QRL) is happy to release the second part of a four part series for developing efficient post-quantum finance in an adversarial world. In this second part we look at post-quantum secure signature aggregation, a critical component for reducing the on-chain footprint for blockchains using the proof-of-stake consensus with many validators. The articles in this series describe the applications and security models; additionally, open-source python implementations of the cryptography are freely available via GitHub and PyPi (built with the lattice-algebra library described in a previous QRL blog post). www.theqrl.org/blog/techniques-for-efficient-post-quantum-finance-part-2-signature-aggregation/
