Hello. Quick heads up on the upcoming network upgrade.
On Thursday, January 8 at 17:00 UTC, ArbOS 51 “Dia” activates on @arbitrum One and Arbitrum Nova.
If you run a node, this needs your attention. You must upgrade to Nitro v3.9.3 or newer before activation to keep your node syncing normally.
For me, this upgrade reflects Arbitrum’s steady evolution. It adds support for Ethereum’s Fusaka EVM changes and improves the gas pricing model to reduce sharp fee spikes during high demand.
Key points for builders and users.
- secp256r1 support is updated via EIP-7951 - BLS12-381 precompiles are now fully enabled - A per-transaction gas limit cap improves block fairness - Instrumentation is added for future constraint based pricing
This is a meaningful under the hood upgrade. If you build on Arbitrum, expect steadier performance during busy periods.
