[PYTHON] Stellen Sie mit Pybitcoin-Tools eine Verbindung zu einem Bitcoin-Netzwerk her

Was sind Pybitcoin-Tools?

• Bibliotheks- und Befehlsdienstprogramm für die Interaktion mit dem Bitcoin-Netzwerk
• Erbaut von Ethereum-Gründer Vitalic Buterin
• Kann auch mit dem Befehl pybitcointools ausgeführt werden
• Kann eine Verbindung zu Electrum herstellen (ein leichter Bitcoin-Client, bei dem Freiwillige alte Bitcoin-Client-Knoten über die API bereitstellen)
