We’re extremely happy to announce that Offchain Labs is acquiring Prysmatic Labs, the team behind Ethereum's leading consensus client!

This will bring Prysmatic Labs underneath the umbrella of Offchain Labs - a merge of two layers, if you will! 🤝

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. 🧵

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 🧮
