Rayonism☀️, hacking the Merge collectively
This week, protolambda and others launched plans for Rayonism, an bold month-long hack to create Merge devnets primarily based on present specs with a stretch objective of including sharding to those devnets together with L2 rollup integrations.
The first motivation is to unite growth round a unified Merge spec to onboard all consumer groups firmly into the Merge design and course of in order that an knowledgeable choice on the Merge roadmap could be agreed upon within the coming months. That, and have a bit little bit of enjoyable 🙂
Along with Rayonism, Merge specs and design documents are making nice progress. Enormous shout-out to Mikhail and to the numerous reviewers and contributors pushing this alongside!

blst safety advisory
Yesterday, Supranational launched a security advistory for the blst BLS library that’s at the moment in use in manufacturing by all beacon chain purchasers as we speak.
Through the course of differential fuzzing of the blst library by Guido Vranken, he found that blst can produce the inaccurate outcome for some enter values within the inverse perform. This was patched in a blst release three weeks go and has been launched into all beacon chain purchasers.
Though there’s at the moment no identified sensible exploit of this difficulty, it’s suggested that everybody operating beacon chain purchasers improve to the most recent model in case an exploit is uncovered. Equally, for those who use blst in your undertaking, we extremely suggest bumping to the most recent model as quickly as attainable.
[Note: Teku was not running an affected version of blst, but they have some juicy optimizations recently so you might as well upgrade anyway]
You possibly can learn extra about this difficulty within the public security advisory on the blst repo.
Beacon Chain safety+testing RfP
Reminder! There’s an impressive Beacon Chain security+testing RfP.
The EF is on the lookout for any proposals that additional the safety and robustness of the Beacon Chain and the upcoming merge (migration from PoW to PoS). Reside community evaluation, formal verification, consumer load testing, new consensus vectors — simply to call just a few potential paths.
Get inventive! Given you and your group’s skillset, there’s seemingly a worthwhile strategy to contribute to the safety of this technique.
Proposals are due April twentieth 🚀
