Important Update for Gravity Node Operators The Gravity team is pleased to announce that we have adopted the ArbOS 51 (Dia) upgrade on Gravity Alpha Mainnet. This upgrade incorporates key improvements aligned with the Ethereum Fusaka upgrade roadmap: What's Included: - Features from the ArbOS 40 (Callisto) upgrade - Foundation for Permissionless Fault Proofs via the new BoLD dispute protocol - Clear Path to enabling Native Token Mint/Burn capabilities - Transaction gas limit cap for more efficient gas usage (EIP-7825) - Cheaper and more efficient cryptographic operations through updated precompiles and opcode changes Required Actions: No action required if you are not running external nodes. If you or your partners are operating external nodes: - Upgrade your Nitro node to at least v3.9.3 (v3.9.5 is recommended) - Ensure the flag --node.staker.enable=false is set in your node configuration Post Upgrade Notes: Once the upgrade is complete, your chain’s chainInfo.json file will be updated automatically. We have updated our node setup documentation to reflect these changes. Please initiate the upgrade as soon as possible; nodes running older versions will be unable to sync the latest blocks. If you have any questions, please don’t hesitate to reach out.
