However, when broken down by the volume of significant attacks, BNB chain represented 26-- over half of them. The chain signs up with Ethereum, Fantom, and Cronos as having actually suffered significant attacks for 2 quarters in a row. By contrast, Solana was walloped with $374 million in losses throughout 2 exploits in Q1 however suffered no significant attacks in Q2.
