Here is a step-by-step guide on how to retrieve input addresses and amounts from V Vin transactions in Bitcoin Core RPC using bitcoin-cli:
Step 1: Connect to Bitcoin Core RPC
First, you need to connect to the Bitcoin Core RPC server. Open a terminal or command prompt and run:
bitcoin-rpc --
This will start the Bitcoin Core RPC server on port 8332.
Step 2: Get block data using bitcoin-cli
Use bitcoin-cli to get the block data:
bitcoin-cli getblock 1234567890
Replace 1234567890 with the block hash you want to retrieve. This will output a JSON object containing information about the block.
Step 3: Get transaction details using bitcoin-cli
Use bitcoin-cli to get the raw transaction data:
bitcoin-cli getrawtransaction 1234567890
This will output a string containing the transaction details in a format suitable for parsing. Note that this will include all transactions, including those with no input addresses or amounts.
Step 4: Parse V Vin transactions
To extract input addresses and amounts from V Vin (Voting Vin) transactions, we need to parse the raw transaction data using JSON parsing. You can use libraries like json in Python to achieve this:
import json
Assume tx_data is the raw transaction string
data = json.loads(tx_data)
Iterate over each transaction in the raw transaction data
for tx in data['transactions']:
Check if the transaction has V Vin (Voting Vin) property
if 'vin' in tx and isinstance(tx['vin'], dict):
Extract input address and amount from V Vin properties
input_address = tx['vin']['address']
amount = tx['vin']['value']
print(f"Input Address: {input_address}")
print(f"Amount: {amount}")
else:
print("No V Vin transactions found")
This code assumes that the tx_data string is the raw transaction output. The JSON parsing library json loads the data into a Python dictionary, which we can then iterate over to extract the input address and amount from each transaction.
Note: This code only prints the extracted information to the console. You may need to modify it to store or persist the results for further analysis or use cases.
I hope this helps you retrieve the desired information using Bitcoin Core RPC!
