Count transactions that match given conditions

When Multiple conditions are given, they are considered as AND condition.

Parameters:

• domain_id (bytes) – target domain_id
• asset_group_id (bytes) – asset_group_id that target transactions should have
• asset_id (bytes) – asset_id that target transactions should have
• user_id (bytes) – user_id that target transactions should have

Returns:

the number of transactions

Return type:

int

insert_transaction(domain_id, txdata, asset_files)

Insert transaction into ledger

Parameters:

• domain_id (bytes) – target domain_id
• txdata (bytes) – serialized transaction data
• asset_files (dict) – dictionary of {asset_id: content} for the transaction

Returns:

inserted transaction_id or error message

Return type:

dict|str

quit_program()
