In response to two Beacon Chain finality issues, Ethereum core developers introduced patches for Prysm Labs and Teku clients in a matter of 24 hours.

The Beacon Chain on the Ethereum network serves as the consensus layer, and on May 11, Ethereum developers reported issues surrounding confirming transactions. While new blocks could be proposed, an unknown issue emerged and their finalization was prevented.

This outage lasted nearly 25 minutes, and a similar issue repeated on May 12 which witnessed the prevention of finalization for more than one hour. An Ethereum consultant on Twitter stated that finality was unable to be reached for three and eight epochs, and that the issue at hand “appears to have been caused by high load on some of the Consensus Layers clients, which in turn was caused by an exceptional scenario.”

As a response, Teky and Prysm have released upgrades which implement optimizations that prevent beacon nodes from consuming excessive resources, and that has seemingly fixed the hurdle on the most prominent network of the cryptocurrency world.
