Starknet explains the reason for the four-hour block interruption: due to the Rounding Error vulnerability

Ethereum Layer2 protocol Starknet suffered a block reorganization, resulting in a backlog of transactions. The protocol's block monitoring tool Starkscan shows that block production was interrupted for four hours. Starkscan shows that there is a time gap between the creation of blocks 630028 (10:30:26, April 5) and 630029 (14:16:15, April 5) on April 5, while Starknet's status page does not reflect any failures on the network that day. It is reported that Starknet has issued a statement on the X platform, explaining that a rounding error vulnerability caused the reorganization of the block. The company said that block production continued as usual, but the reorganization caused the transaction backlog to reach its limit. The post explained: "As a result, for a few minutes, new transactions could not be accepted for processing and were therefore rejected. In addition, some transactions were revoked due to changes in parameters (such as timestamps). "The media contacted Starknet to confirm the details of the incident, but has not received more information and whether block production has been stopped according to block data. (Cointelgraph)
