Ethereum core developers rolled out patches to Prysm Labs and Teku clients within 24 hours to deal with two beacon chain finality issues. The beacon chain acts as the consensus layer for the Ethereum network.
On May 11, ethereum developers reported that the beacon chain was having trouble confirming transactions. Although new blocks could be proposed, an unknown issue prevented them from being finalized. The outage lasted about 25 minutes. A similar issue occurred on May 12, preventing blocks from being finalized for more than an hour.
In a statement shared by an ethereum advisor on Twitter, the Ethereum Foundation said that a final outcome could not be reached within three and eight periods. The issue "appears to be caused by high load on some consensus layer clients, which in turn is caused by anomalous conditions." Although the network cannot be finalized, real-time users and end users are able to transact on the network due to the diversity of clients, "as not all client implementations are affected by this particular situation."
Client diversity is related to the number of software clients available to a network validator. Greater diversity among clients means a stronger and more secure network.
Teky and Prysm have released upgrades implementing optimizations to prevent beacon nodes from consuming too many resources.
A similar issue occurred on March 15, delaying the Goerli testnet version of Ethereum’s “Shapella” upgrade, which was successfully deployed on April 12. Ethereum's pre-existing proof-of-work chain merged with the beacon chain on September 15, 2022, enabling the network's transition to a proof-of-stake consensus mechanism that is faster and less energy-intensive.
The recent trading hype surrounding memecoins has increased Ethereum activity and return on stake. According to on-chain data, validators earned $46 million, or 24,997 Ether, in the first week of May, a 40% increase from the previous week’s $33 million in revenue, when 18,339 ETH was distributed as rewards.
