# Last Month at QRL - September 2022 > For the complete documentation index, see [llms.txt](/llms.txt). This markdown page mirrors [the canonical HTML page](/blog/last-month-at-qrl-september-2022/). The official Public Devnet Launch of Zond with EVM Smart Contracts and Proof-of-Stake! A number of interesting ideas were presented at the first real-world QRL Hackathon in 2022, and the community was fantastic. The winning entry, QRLPay, won with being a simple, quick-to-deploy, lightweight QRL payment processor and woocommerce website that connects to your own QRL node Published: 2022-10-03 Updated: 2022-10-03 Author: Jack Matier Categories: technical, events Features: proof-of-stake Highlights Zond Public Devnet Released! Last month we were happy to release the QRL Zond public devnet, bringing post-quantum resistant Web3 and EVM compatible smart-contracts on top of a Proof-of-Stake consensus layer. This development has built off of our years of experience and research in the blockchain development space and represents a shift to truly programmable and efficient post-quantum secure finance available to anybody. There is now the potential for on-chain escrow, as well as the provision of loans, insurance, mortgages, and various other improved financial instruments. Compatibility with Ethereum through Web3 and EVM means that the migration learning curve is small. You can read our “Introducing a powerful post-quantum safe public devnet pre-release with Ethereum Web3 ecosystem compatibility” which covers many of the basics. Our Zond Documentation is also continuously being fleshed out, as well. The QRL Hackathon 2022 Our first in-person QRL Hackathon 2022 was broadly successful with many interesting entries and many more amazing community members! QRLPay walked off with the first prize of 40,000 QRL which combines a simple, easily deployable lightweight QRL payment processor that connects to your own QRL node and a woocommerce website. This was spearheaded by a Discord member 0xFF, with runforest handling the presentation. Other great entries includes a Mobile Wallet, PoS/Validator dashboard, and better support for the Raspberry Pi! More about these entries can be found in our QRL Hackathon 2022 entries blog. Were you there, or did you have difficulty making it? Be sure to fill out our QRL Hackathon 2022 survey which will help guide us shortlisting our next hackathon location and activities! While the event was organised by the team at QRL, it wouldn’t have been possible without the community members and contributors that joined us. We really look forward to all the future events together!
