Hands-On Blockchain for Python Developers

Thread classes

Now, let's write thread objects in order to access the blockchain. When creating a transaction in a blockchain, you usually want to use a thread or non-blocking function. Consequently, every time we want to broadcast a transaction, we use these thread classes. These thread classes will use the blockchain object that we have described previously.

Use the following code block to create a balance_thread.py file in the wallet_threads directory:

from PySide2.QtCore import QThread, Signalfrom time import sleepfrom blockchain import blockchainclass BalanceThread(QThread):    get_balance_transaction = Signal(map)    def __init__(self, parent=None):        super(BalanceThread, self).__init__(parent)        self.quit = False    def kill(self): self.quit = ...
