Ethereum Clients Release Crucial Updates As Blockchain Suffers Two Outages in 24hrs

Ethereum consensus clients Prysm and Teku released new updates to fix the recent Beacon Chain finality issues. The Ethereum network suffered from finality issues two times within 24 hours, first for 25 mins and the second time for over an hour. This does not impact end users and transactions, but concerns stakers and developers.

According to Ethereum Foundation, it takes about 15 mins for an Ethereum block to finalize. “Finality” refers to the guarantee that a block cannot be modified or removed from the blockchain without burning at least 33% of the total staked ETH.

Ethereum Clients Announce Fixes For Finality Issues

Prysm Ethereum Client announces the v4.0.3-hotfix on May 13. The release contains the necessary optimization to prevent the Beacon Chain node from high resource usage during turbulent times. The client has highly recommended Ethereum node operators to upgrade their node if it’s under heavy resource usage.

According to Prysm, an increase in validator sizes and untimely old attestations stresses the nodes’ CPUs and bloats memory usage. The release will make a node ignore attestation for an old target and prevents issues in the future.

Ethereum client Teku also released the v23.5.0 update on May 13. Similar to the Prysm release, this update filters old attestations that caused problems on the Ethereum mainnet. The bug fix includes several additions and improvements to prevent issues.

Meanwhile, Ethereum client Nimbus asserts no critical upgrade is required for its users. However, it will continue to monitor and release fixes if things degrade further.

Interestingly, Ethereum clients Lighthouse and Lodestar did not suffer a high load due to a different design. While other consensus layer clients on Ethereum experienced high resource usage, Lighthouse and Lodestar kept the network live throughout the incident at 40-50% of blocks until the other clients recovered and blocks finalized.

Ethereum influencers noted the critical importance of Ethereum’s client diversity that save Ethereum from a major outage. Ethereum blockchain remained resilient against partial failures, then recover and finalize.

The critical importance of Ethereum's client diversity goes unappreciated 99.9% of the time.

But it counts for everything during the 0.1% of times that something goes wrong.

Sending kudos to the heroes who build and maintain Ethereum clients 🙏
