Overview is an a scalable, high-throughput Proof-of-Stake blockchain that is fully compatible and interoperable with Ethereum.

Affected versions of this package are vulnerable to Storage Caching Lifecycle Inconsistency. Due to the inconsistency between the Storage caching cycle and the TX processing cycle, Storage changes caused by a failed transaction are improperly reserved in memory. Although the bad storage cache data will be discarded at EndBlock, it is still valid in the current block, which enables many possible attacks (such as an "arbitrary mint token").
