Last Month at QRL - April 2022

Last month the QRL team was excited to announce the September 2022 hackathon unveiling PoS and EVM compatible smart contracts. Geometry Labs, in partnership with QRL, released the first part of techniques for efficient finance series with more to come!

QRL Hackathon 2022

The QRL protocol’s future lies in a public blockchain powered by proof-of-stake that is environmentally friendly, completely decentralized, and capable of provably post-quantum secure transactions and Turing complete smart contracts. New and novel use-cases like dApps, DeFi applications, quantum-secure stablecoins, NFTs, and metaverse applications can be created by provably post-quantum safe Web3 capabilities. Using the QRL ecosystem, blockchain code may be made quantum-secure by anyone’s vision. Choosing to implement the EVM into the QRL protocol enables smart contract compatibility and interoperability with other EVM chains.

Which is why the QRL team was excited to announce the upcoming ‘Build on QRL Protocol’ hackathon event, which will take place in September 2022 where the upcoming network upgrade which includes Proof-of-Stake with compatible Ethereum Virtual Machine (EVM) smart contract functionality will be unveiled, demonstrating the future of post-quantum secure blockchains.

We’re happy to say we’ve narrowed it down to a single location and are getting other details sorted out before revealing. Stay tuned!

Techniques for Efficient Post-quantum Finance Series

The series starts with revealing lattice-algebra, a library with the goal to lower the barrier for creating lattice cryptography primitives and applications by allowing the developers to focus on securely building the higher-level constructs without having to worry about implementing the underlying algebra as well. In short, it is designed to make it easy for developers to write efficient, clean code which implements lattice-based cryptography for protocols and applications - something not readily found in current libraries and something sorely needed to help usher in the era of post-quantum finance.

This was then been followed up with post-quantum secure digital signatures, which describes lattice-based one-time signature scheme similar to the one published by Lyubashevsky and Micciancio. Since our scheme also has some similarities to CRYSTALS-Dilithium (a NIST post-quantum standardization candidate), there are general applications for our discussion below regarding optimizations for smaller keys and signatures in the lattice setting.

Building off of Lyubashevsky and Micciancio, we introduce Boneh and Kim style post-quantum secure signature aggregation, which has several potential applications such as reducing the on-chain footprint for proof-of-stake consensus with many validators, implementing m-of-n multisignature wallets, and on-chain governance.

From there, we’ll be taking a journey through two additional parts to the series, post-quantum secure adapter signatures and fountain architectures. Adaptor signatures is a secondary signature that is used in conjunction with an initial signature to reveal a piece of secret data, resolving the trust issue inherent in concurrent transactions such as atomic swaps. Fountain architectures is a method to significantly reduce the overall blockchain size in a way that remains secure. This is an evolution over light clients (which don’t validate transactions - vulnerable to security and privacy attacks), and block pruning (deletes old blocks after being validated - requires archival nodes to remain on the network). Worth a read is “SeF: A Secure Fountain Architecture for Slashing Storage Costs in Blockchains” which managed to slash storage costs by 1000x, bringing the Bitcoin network down from 191GB to 195MB.

While some effort has been made to make everything understandable, this article series is aimed at systems integrators and cryptography students. We will be maintaining an open AMA form throughout the “Techniques for efficient post-quantum finance” series to address any technical or non-technical questions that may arise, and encourage anyone to use it!

Other developments

Non-fungible Tokens (NFTs)

Early this month we put out a call-to-action for NFT Platform Providers which connects with our call-to-action for NFT creators earlier this year. Since then, we are pleased to announce that we have gathered interested parties and allocated development resources to assist in the development of post-quantum secure NFTs.

Developer Expansion

There are currently three candidates who have been shortlisted and will be subjected to additional evaluations over the next few months. These developers will work along with the rest of the development team to build out our Proof-of-Stake and EVM compatible smart contract platform, though importantly will not limit the ability to have a public devnet for our QRL Hackathon 2022.


EnQlave was founded in early 2020 after it was discovered that we could bring post-quantum security to the Ethereum blockchain (with costs). This pledged to give back to the Ethereum community while also introducing Ethereum to the QRL blockchain ecosystem and providing a bridge in the form of Uniswap. We had a prototype by April 2021 and determined that the project was viable.

Within weeks of the announcement, the average Ethereum gas fees skyrocketed by several factors. In spite of this, work was carried on until the end of 2020, when it was subjected to an audit. Unfortunately, as gas prices refused to recede, it was necessary to make changes in order to keep the project viable and so hash-chains were implemented. This corresponded with a development change to Kaushal/JP, while Charlie finished his final year of high school. Charlie is back as of late 2021/early 2022 (note: dev changes can take months to get acquainted with code) and will be preparing an update on EnQlave.

Since then, Charlie has returned to EnQlave in late 2021 (please keep in mind that development changes can take months to become familiar with the code) and will be working on an update that many are eagerly awaiting.

Website Improvements

We’ve updated to Hugo v97.3 from v74.1 (released early 2020!), which has many additional features such improved i18n handling (stay tuned!) and better file handling & management, which has allowed for the ability to significantly clean things up.

Other adjustments we’ve made have been the addition of Google Analytics 4 (running alongside of Universal Analytics 3 for now, but will supersede it) to continue being able to properly track and analyze milestones and evaluate the effectiveness of various initiatives. MathJax has gone through a downgrade from v3 to v2 to better match workflow with hackmd and spearhead content (hope you’re enjoying the LaTeX in the Geometry Labs blogs!). Additional features added are guest blogs and the ability to handle series for both video and written content!

OpenSSH now defaults to protecting against quantum computer attacks

“Post-quantum cryptography has arrived by default with the release of OpenSSH 9 and the adoption of the hybrid Streamlined NTRU Prime + x25519 key exchange method.” - zdnet

PsiQuantum’s Path to 1 Million Qubits

“PsiQuantum says it will have all the manufacturing processes in place “by the middle of the decade” and it’s working closely with GlobalFoundries (GF) to turn its vision into reality. The generous size of its funding suggests many think it will succeed. PsiQuantum is betting on a photonics-based approach called fusion-based quantum computing (paper) that relies mostly on well-understood optical technology but requires extremely precise manufacturing tolerances to scale up. It also relies on managing individual photons, something that has proven difficult for others.” - hpcwire
