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 For more information about release changes see: https://github.com/OffchainLabs/nitro/releases.

Hey Arbinauts! Arbitrum Autumn has been going strong and as we crest into November we wanted to share some progress we’ve made towards decentralization. 🧵 https://offchain.medium.com/39f093768c42 Validator nodes secure the Arbitrum One chain by posting assertions to the state of the chain, and challenging any fraudulent assertions made by other validators. 🖥️ So in anticipation of permissionless validation, we are expanding the validator set.. Today we’re excited to announce an expanded validator set! The broadened group of organizations securing the Arbitrum One chain now include: ConsenSys 🌀 Ethereum Foundation 💜 L2beat ❤️ Mycelium 🍄 Offchain Labs (us) P2P Validator ✔️ QuickNode 📍 Distributed Ledgers Research Centre (DLRC) at Institute for the Future (IFF) 🔴 Unit 410 🧮
