The new Arbitrum validators represent a variety of organizations and different communities so that many users can have comfort in a diverse set of validators securing the chain! 🌐↔️🌎

We look forward to continuing to share more around our plans for validation soon!

Including some exciting validator protocol updates and fully permissionless validation. 👀
This was all made possible by the upgrades we shipped in September that reduced performance costs for validator nodes by more than 90%! ⬇️

This heavily reduced the compute costs associated with running validator nodes by making the act of block validation incredibly performant. 💪

This was a crucial upgrade necessary to enabling decentralization in the long term.

Allowing more people to cheaply and easily operate validator nodes that secure rollup chains is a core tenet of mass participation and sustainable decentralization. 💻🌎

Decentralization is a long process, and while we're super excited about today's update, we’re even more excited to keep making progress towards further decentralization.

Stay tuned across our channels so you can be informed on our upcoming developments! 😉

As always, we’re hiring!

So if you want to be a part of the team that’s building out the future of decentralized scaling solutions visit our careers page below!

We can't stress how thankful we are to all of you, our fellow Arbinauts! 💙🧡

Hi Arbitrum fam 👋
We have a new Nitro release! 🚀 With this, Nitro nodes now support RPC queries with the "safe" and "finalized" block numbers. This release also includes various bug fixes and improvements. While this release isn't tied to a consensus upgrade, please upgrade when possible. 🛸

🎉 This new version 2.0.10 is meant to enable our protocols and developers to have a clear understanding on the state of block finality in Nitro, similar to Ethereum.

Release notes here: https://github.com/OffchainLabs/nitro/releases/tag/v2.0.10
Docker Hub: https://hub.docker.com/layers/offchainlabs/nitro-node/v2.0.10-73224e3/images/sha256-e132ff6837f96a36b14975e8227d462260c5e1fbfaafaed8ba69433b6cb290df?context=explore
