According to PANews, Ethereum Layer2 protocol Starknet suffered a block reorganization, resulting in a backlog of transactions. Starknet's block monitoring tool Starkscan showed that there was a four-hour gap between blocks 630028 and 630029 on April 5, but Starknet's status page did not reflect any failures on the network that day.

Starknet released a statement on the X platform, explaining that a rounding error bug caused the reorganization of the block. Block production continued as usual, but the reorganization caused the transaction backlog to reach its limit. New transactions could not be accepted for processing and were therefore rejected. Some transactions were revoked due to changes in parameters (such as timestamps). At present, Starknet has not provided more information on this incident.

Notably, Starknet’s status page last reflected a major outage on March 13, when its network experienced slow block creation rates due to Ethereum’s Dencun upgrade.
