pub struct StaleHashCheckExtension;
Expand description
The SignedExtension trait is implemented on StaleHashCheckExtension to validate the request. The purpose of this is to ensure that the target_hash is verified in transaction pool before getting into block. This is to reduce the chance of capacity consumption due to stale hash
