Key point 3 of 3
03
Node operators must update their software to versions that do not include the scheduled Hoodi activation.
Context
The delay highlights the complex interactions between Ethereum's L1 scaling roadmap and existing smart contracts, particularly when gas pricing models change.
Why it matters
Node operators on Hoodi must update their clients to avoid splitting off the network. Application developers must verify if their contracts are vulnerable to the invariant changes.
What to watch
A new activation schedule for Hoodi will be announced once core developers resolve the smart contract vulnerability issues.
