Geth-Version: 1.8.12-stable-37685930
Test auf Amazon EC2 t2.large (8 GB RAM)-Maschine mit Ubuntu 16.04 ausgeführt.
Ich muss ein privates POA(Clique)-Ethereum-Netzwerk mit mehreren Knoten einrichten. Zunächst teste ich mit der Einrichtung eines Single-Node-Netzwerks mit zwei Konten. Beim Einrichten eines Genesis-Blocks durch Puppeth weise ich 1 Konto als Sealer und 1 Konto als eines zu, das mit Ethern finanziert werden soll). Ich kann ein Netzwerk einmal einrichten, aber auch einen Vertrag darauf bereitstellen, aber,
Mich stören vor allem zwei Fehler.
1) Der Kontostand, den ich in der genesis.json finanziere, wird 0, sobald die Blockchain einen Tag lang läuft. Sobald dies passiert, wird meine Blockchain nutzlos, da ich keine Möglichkeit mehr habe, Guthaben auf Konten in POA zu erhalten.
2) Mein Geth stürzt nach einem Tag mit diesem Fehler ab .

......................................
Es geht weiter
Dies ist der Genesis-Block, der durch Puppeth generiert wird

Anhängen der Geth-Protokolldatei.
Ich denke, jemand hat Zugriff auf Ihren Knoten und spammt ihn mit Transaktionen an seine Adresse von Ihren entsperrten Konten. Dies leert Ihr Guthaben und spammt Ihren Knoten so sehr mit tx, dass ihm der Speicher ausgeht.
Die Konten, die Ihren Knoten spammen, sind:
0x7097f41F1C1847D52407C629d0E0ae0fDD24fd58
0x6e4Cc3e76765bdc711cc7b5CbfC5bBFe473B192E
0x8652328B96Ff12B20de5fDc67b67812E2b64e2A6
und es beginnt in Zeile 91425 Ihrer Protokolldatei.
Ihr Ziel ist es, einen Hauptnetzknoten mit entsperrten Konten zu finden und all ihre Gelder zu stehlen.
Sie müssen die RPC-Verbindung zu Ihrem Knoten sichern, wenn Sie "persönlich" verfügbar machen. Verwenden Sie beispielsweise nginx mit einer einfachen Authentifizierung. Siehe dieses Tutorial oder diese Frage Restricted Access / Authentication for a Remote Geth Node .
