methods may be useful for debugging purposes.
#### `submitnotaryrequest` call
#### P2PNotary extensions
The following P2PNotary extensions can be used on P2P Notary enabled networks
only.
##### `getrawnotarypool` call
`getrawnotarypool` method provides the ability to retrieve the content of the
RPC node's notary pool (a map from main transaction hashes to the corresponding
fallback transaction hashes for currently processing P2PNotaryRequest payloads).
You can use the `getrawnotarytransaction` method to iterate through
the results of `getrawnotarypool`, retrieve main/fallback transactions,
check their contents and act accordingly.
##### `getrawnotarytransaction` call
The `getrawnotarytransaction` method takes a transaction hash and aims to locate
the corresponding transaction in the P2PNotaryRequest pool. It performs
this search across all the verified main and fallback transactions.
##### `submitnotaryrequest` call
This method can be used on P2P Notary enabled networks to submit new notary
payloads to be relayed from RPC to P2P.
