I can provide you with step-by-step instructions for inserting data in OP_Return.
Op_Return understand
OP_RETurn is a standardized method for coding Bitcoin transactions in a URL that can easily be decoded by the recipient. It uses a certain format and a certain structure to present every transaction, including the address, the amount and other information from the sender.
Step-by-step instructions for inserting data in Op_Return
- Create a new transaction : Before you can insert data into an OP_Return -URL, you must create a new Bitcoin transaction with
drink transaction. You can use your preferred wallet or library to generate the transaction.
- Prepare the transaction data
: You must prepare the data for the transaction in a specific format. The most common format is:
`Json
{
“TXID”: “Seltyhash”,
“Vout”: [1, 0],
“Occupation”: “some_value”
}
`
Replace Son_hash with the actual hash of your transaction and ‘[1, 0]with the address of the sender.
Coding the transaction data in op_Return : You can use a library likeBitcoinliborJSON-OPSto encode the transaction data to an op_Return string. Here is an example withBitcoinlib:
Python
Import Bitcoinlib
tx_data = {
"TXID": "Seltyhash",
"Vout": [1, 0],
"Occupation": "some_value"
}
op_Return_data = Bitcoinlib.encode_op_Return (tx_data)
Print (op_Return_data)
edition: "Some_hash-vout [1.0]: some_value op _..."
- Create an OP_Return -Url : Now that you have the coded transaction data, you can create an OP_Return -URL with a library like
BitcoinURL. Here is an example:
`Python
Import BitcoinURL
op_Return_URL = BitcoinURL.encode_op_Return (op_Return_data)
Print (op_Return_urn)
output: "
- Decode the op_Return URL : To decode the URL of the OP_Return, you can use a library such as “JSON-OPS” or
Bitcoinlib '. Here is an example withJSON-OPS:
Python
Import JSON
Op_Return_data = "special_hash-vout [1.0]: Sole_value op _..."
coded_data = op_Return_data.encode ("utf-8")
decoded_data = json.loads (coded_data)
print (decoded_data)
output: {"txid": "selty_hash", "vout": [1, 0], "quantity": "slow_value"}
Error treatment
As you have already mentioned, you will receive an error with `"code": -22, "...} on “Signrawtransaction”. This error normally occurs if the transaction data is not valid or cannot be encoded in op_Return . In check this case:
- The transaction data are in the correct format (e.g.
txid,vout,pension)
- The address of the sender is correctly linked to the transaction
If you still have problems, you are welcome to provide more details about your error message and I will be happy to help!
