The Cosmos Hub is stable and running normally. The funds secured during the restart came from the Neutron governance attack and were bridged to the Hub; there was no vulnerability on the Hub itself. They are now held in a community validator multisig. Hub validators, the Neutron ecosystem, and affected protocols are coordinating on recovery. Neutron will share a post-mortem, and a Hub forum update will follow in the coming days. Thank you to all validators and community members for the swift, coordinated response in support of another network.

We have begun to burn 100M LSK Tokens, aiming to reduce the overall LSK supply from 400M to 300M tokens. This results from the successful passing of our DAO proposal. Here is why, and what it may mean for you. 🧵 (1/7)

The Protocol Cluster has published two new posts: Hegotá EIP Opinion Post and Tier List evaluates and grades all 62 EIPs proposed for Hegotá, providing the cluster’s first unified tier list for a network upgrade Current and Emerging Priorities covers commitments and research arcs, anchored on a quantum-resistant Ethereum L1 by Dec. 2029 Offered as one input to Hegotá scoping, roughly 60 researchers, engineers, and individual domain experts across all 9 teams in the Protocol Cluster contributed to the Hegotá tier list, providing 397 tier grades before discussing contested items live. The plan, commitments, and shared set of cluster-wide priorities covered in the companion post provide the context behind the final tier grades. The Protocol cluster will host a Reddit AMA on r/ethereum on September 16 at 2pm UTC to talk through these priorities, the Hegotá tier list, and anything else on your mind. → Submit questions ahead of time here: pad.ethereum.org/form/#/2/fo… Read the articles here: → EF Protocol - Current and Emerging Priorities: blog.ethereum.org/2026/09/07… → EF Protocol - The Hegotá EIP Opinion Post and Tier List: blog.ethereum.org/2026/09/07…

The first Testnet reset is scheduled for October 7. Testnet returns to a fresh genesis: deployed contracts, test accounts, balances, and history are cleared and need to be redeployed. No effect on Mainnet or Devnet.
