Ethereum core developers rolled out patches for Prysm Labs and Teku clients as a response to two Beacon Chain finality issues within a 24-hour period. The Beacon Chain serves as the consensus layer for the Ethereum network.
On May 11, Ethereum developers reported that the Beacon Chain was experiencing problems confirming transactions. Although new blocks were able to be proposed, an unknown issue prevented their finalization. The outage lasted around 25 minutes. A similar issue took place on May 12, preventing block finalization for over an hour.
