Proof of Stake

Proof-of-Stake is a blockchain consensus mechanism that will be replacing Proof-of-Work in QRL. Instead of computers competing for who would win the block by computing a piece of work, a validator is selected at random by the weight of their holdings.

QRL currently has a post-quantum secure Proof-of-Stake devnet and code, codenamed project Zond which lays out some of the framework that may be used for our upcoming proof-of-stake system. With the aim to provide the most reliable, efficient, and flexible, post-quantum secure proof-of-stake protocol, additional competing areas of research and development are being pursued between STARKs (with hash-based cryptography), and lattice-based cryptographic solutions.

Techniques for efficient post-quantum finance (Part 2: signature aggregation)

technical research

This is the second article in a multipart series from The QRL Foundation and Geometry Labs exploring signature aggregation, a critical component for reducing the on-chain footprint for blockchains using the proof-of-stake consensus with many validators

Techniques for efficient post-quantum finance (Part 1: digital signatures)

technical research

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.
