Method Details

isPermitted

boolean isPermitted(org.hyperledger.besu.datatypes.Transaction transaction)

Can be used to filter transactions according to an arbitrary criteria. Registered providers are consulted as part of transaction validation, so rejecting a transaction keeps it out of the transaction pool and causes it to fail block-level transaction validation.

Parameters:

transaction - the transaction to check

Returns:

whether the transaction is permitted
