On May 11th, the Ethereum blockchain mainnet was unable to fully verify transactions for approximately 25 minutes. The transaction was then confirmed, but exposed to tampering for 25 minutes.
An Ethereum core developer has posted on Twitter that the blockchain has not been finalized, revealing that the issue is being investigated. I’ve had similar problems in the past, but this time it was due to a bug in the client software.
But in seriousness – the beacon chain had a brief period of non-finalization just now. Good illustration for the robustness of the chain – while there was some slowdown of blocks, transactions continued to be processed as usual. https://t.co/QyRW91OFJ9

The developer says they will report the cause to the community in the near future.
Mainnet has been finalized, and we are investigating the incident now. More to come!
