Here is an article about creating a series of python commands that listens to web Bitcoin events and observe addresses stored in the MySQL database:

Ethereum: The starting point for listening to web Bitcoin events in Python

Bitcoin, the second largest cryptocurrency in market value, uses a decentralized node network to validate and save events. In this article, we analyze how to create a Python script that listens to the Bitcoin network and monitors addresses stored in the MySQL database.

Prerequisites

• You have basic information about Python and MySQL.

• You have a bitcoin node (for example, Bitcoin Core) installed on your machine.

• You have a mysql database created and filled with Bitcoin event information.

Step 1: Install the required libraries

Before we start, you need to install the following libraries:

• Mysql-connector-python 'interact with mysql databases

• Py bitcoin-coreto work with bitcoin events (note: this is not a complete implementation of Bitcoin Knot)

To install these libraries with PIP:

Bash

PIP Install mysql-conector-python pybitcoincore

`

Step 2: Create Python Command Series

Create a new Python file, for example, “bitcoin_listener.py” and add the following code:

`Python

Bring mysql.connector

Bring Json

MySQL Database Settings

Db_host = ‘localhost’

Db_user = ‘your_username’

Db_password = ‘your_password’

Db_name = ‘bitcoin_transactions’

Bitcoin Node Settings

Bitcoin_node_url = ‘

Bitcoin_node_secret = ‘your_secret_key’

This should not be shared in public

DEF connect_to_tosusql ():

“” Create MySQL Database “” “

Return mysql.connector.connect (

host = db_host,

User = db_user,

password = db_password,

Database = db_Name

In

DEF get_bitcoin_transactions ():

“” “Recover Bitcoin’s Bitcoin events” “

Send the P2P request to the Bitcoin node

Answer = Request.get (bitcoin_node_url)

Data = json.loads (response.text)

Disassemble the addresses and quantities of the transaction

Events = []

From data in the data [‘events’]:

Address = item [‘de’]

Quantity = item [‘value’]

Events.append ({

‘Address’: Address,

‘Quantity’: Quantity

})

Return the events

DEF Main ():

“” Listen to Bitcoin web events “”

Create MySQL database connection

db_connection = connect_to_tusql ()

Search Node Bitcoin Events

Events = Get_BitCoin_Transactions ()

Ite transactions and follow the addresses in the MySQL database

at events at events:

Address = Event [‘Address’]

Quantity = event [‘quantity’]

Check that the address is in the MySQL database

cursor = db_connection.cursor ()

Query = “Select * Bitcoin_transations with address =%s and time stamp> =%s”

Course.

Result = Course.Fetchone ()

If the address is found, update your quantity and date and time registration for the database

If the result:

New_amount = event [‘quantity’] + 10

simulates the event with 10 units beyond

Questionnaire = “Update bitcoin_transations define quantity =%s, timestamp = now () where address =%s”

Course.Execute (Inquiry, (new_mount, address)))

Print the results on the console

Print (F “Address: {Address} | Number: {Quantity} | Timestamp: {datetime.now ()}”)

Close the MySQL database connection

db_connection.
