Response body in successful cases:

{    "jsonrpc": "2.0",    "id": 1,    "result": {        "hash": "0x13ccdb9f7eda95a24aa5a4841b24fed957fe7f1b944996cbc2e92a4fa4f1fa73"    }}

Response body in unsuccessful cases:

{    "jsonrpc": "2.0",    "id": 1,    "error": {        "code": -500,        "message": "AlreadyExists"    }}

Response Description:

When result is false, the current transaction has failed to broadcast and an exception occurs. In this example, a confirmed transaction is broadcast, which fails due to the double cost.

The following error codes can be expected:

	UnableToVerify	The block cannot be validated.
	Invalid	The format or parameter is incorrect
	Expired	The block information is expired
	InsufficientFunds	Insufficient funds
	PolicyFail	The behavior is not allowed (such as blacklist address trading)
