Conclusion

The release of Lighthouse hot fix v4.0.2-rc.0 is an important development in ensuring the stability and security of the Ethereum 2.0 network. Main network users are highly recommended to update their beacon nodes to this version to prevent high CPU usage from interfering with normal node operations.

FAQs

1. What is a beacon node?
A beacon node is a type of Ethereum 2.0 node that is responsible for validating and storing data on the network.
2. Can Validator Client be upgraded as well?
No, the hot fix is only applicable to beacon nodes and does not require upgrading the Validator Client from v4.0.1 (or v4.0.1 rc.0) to this version.
3. What should I do if I am still experiencing high CPU usage after updating to v4.0.2-rc.0?
