On May 11, 2023, Ethereum experienced transaction processing issues for approximately 25 minutes, causing transaction finality issues.

The root cause of the issue is currently unknown, but the blockchain is now functioning normally. Developers, including Ansgar Dietrichs and Prysmatic Labs co-founder Preston van Loon, are investigating the issue and providing updates to the public. This incident occurred during discussions about the next hard fork, called "Dencun," which will feature the Ethereum Improvement Proposal (EIP) 4844. Despite the issue, the Ethereum community is focused on continuing to strengthen the network.
