Ethereum client Lighthouse has released a new hot fix version to address the issue of high CPU usage

On April 13th, it was reported that the Ethereum client Lighthouse has released a hot fix version v4.0.2-rc.0, which addresses the issue of high CPU usage after Capella upgrade. It is recommended that all main network users update to this version to prevent high CPU usage from interfering with normal node operations (such as pledging). This 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.

**Introduction**
On April 13th, it was reported that the Ethereum client Lighthouse has released a hot fix version v4.0.2-rc.0. This version of Lighthouse addresses the issue of high CPU usage after Capella upgrade. This is a significant development for all main network users, as it prevents high CPU usage from interfering with normal node operations. In this article, we will take a closer look at this issue and why upgrading to the hot fix version is essential for seamless operation.
**Understanding the Capella upgrade and its impact on the Ethereum network**
The Capella upgrade is a recent Ethereum network upgrade that introduced some significant changes to the network. One of the most significant changes was the implementation of the eth2-style sync protocol. This new protocol allows for greater scalability, improved stability, and a better overall user experience. However, this upgrade also came with a few issues, one of which was high CPU usage.
**What is Lighthouse?**
Lighthouse is an Ethereum 2.0 client that is written in the Rust programming language. It is designed to be user-friendly, secure, and highly efficient. It is an open-source project that was created by Sigma Prime, a blockchain research group based in Australia.
**The issue of high CPU usage after Capella upgrade**
After the implementation of the Capella upgrade, several users reported a steep increase in CPU usage. The primary cause of this issue was that the client was consuming too much CPU power, causing nodes to slow down significantly. This was causing a lot of problems for users who needed their nodes to perform other operations, such as pledging.
**The Lighthouse hot fix version v4.0.2-rc.0**
In response to this problem, Lighthouse has released a hot fix version v4.0.2-rc.0 of its client software. This version addresses the issue of high CPU usage caused by the Capella upgrade. It is important to note that this 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).
**Importance of upgrading to the hot fix version**
It is essential that all main network users upgrade to the hot fix version of Lighthouse to prevent high CPU usage from interfering with normal node operations. This is particularly critical for those users who rely on their nodes for important operations, such as pledging. Upgrading to the hot fix version will ensure that the node operates at maximum efficiency and is not slowed down by high CPU usage.
**Who should upgrade to the hot fix version?**
All main network users are encouraged to upgrade to the hot fix version of Lighthouse. This includes everyone from developers to individual users running their nodes. The new version of Lighthouse is designed to be user-friendly, so upgrading should not be too difficult or complicated.
**Conclusion**
In conclusion, the release of the Lighthouse hot fix version v4.0.2-rc.0 is an essential development for all main network users. It addresses the issue of high CPU usage caused by the Capella upgrade, ensuring that all nodes can function at maximum efficiency. All users are encouraged to upgrade to this version to avoid any issues that may arise as a result of high CPU usage.
