Sehr hilfreich!!! Darf ich Fragen, wo hast du dein Diagramm? Vielleicht ein Papier, das ich interessiert wäre zu Lesen Vielen Dank, ich habe Ihre Informationen und den screenshot den bug-report. Die neueste version 0.12.1 Sie scheinen zu fehlen den Punkt, dass der Bitcoin ist dezentralisiert. Wenn es eine zentrale Autorität (wie eine bank), der Nachweis der Arbeit, die Bergleute führen nicht notwendig werden würde. Wenn eine bank in Konkurs geht, werden die Mittel in Gefahr. Riesigen Finanzinstitute schlecht benimmt und nicht zurückzuzahlen Völker Mittel scheint zu sein, genau der Grund, warum Bitcoin erstellt wurde. Nein. Sie müssen nur die Kontrolle über Ihre privaten Schlüssel und das scheint der Fall zu sein. Wenn Sie auf einem exchange, der exchange hatte die Kontrolle über Sie. Übrigens: Achtung: Es sind Betrüger im moment, die versuchen, Sie zu "speichern Sie Ihre S2x oder Ihre bitcoins". Fallen Sie nicht für diese. Entschuldigung. Meine ursprüngliche Frage machte es scheinen, als ob ich wurde gefragt, ob ich könnte doppelt ausgeben derselben bitcoins, aus dem gleichen Konto. Ich also meine ursprüngliche Frage b). Zum Beispiel: account x hat 1 BTC. Konto y hat 0 BTC. kann ich offline-Transaktionen senden der 1 BTC von x zu Y (Transaktion A). zur gleichen Zeit, erstellen Sie eine offline-Transaktion senden von 1 BTC von y auf z (das gleiche 1 BTC aus der Transaktion Ein). und dann schicken sich die beiden an das Netzwerk. A, dann B, aber sehr schnell

Nach der Lektüre pebwindkraft Kommentar, ich habe mit einer Antwort.

Der Besondere Extrakt "Zu beheben, muss jeder Knoten wählt immer und versuche zu erweitern, die Kette der Blöcke, die für die meisten Proof-of-Arbeit, auch bekannt als die längste Kette oder den größten kumulativen Arbeit, die Kette"

Wenn die blockchain aktuell:

Block1 -> Block2 -> Block3

Und zwei Bergleute wählen Sie aus den mempool, Transaktionen, die sich nicht überlappen. Dann wird es zu einer Gabel in der blockchain, wenn beide zur gleichen Zeit ausgestrahlt.

Dies ist, weil, obwohl die Transaktion nicht überlappen, die blockhash anders wäre für jeden miner, und wenn Sie den blockhash anders ist, dann ist dies zwei verschiedene Versionen der blockchain. Auch wenn die Transaktionen nicht überlappen.

Wenn miner1 Sendungen zuerst, dann miner2 zu beginnen, seinen block wieder, obwohl alle Transaktionen in miner1 ' s block nicht clash mit miner2 ist. Dies ist, weil, sobald miner1, fügt die blockchain. Die Kette wird:

Block1 -> Block2 -> Block3->Block4

Wo Block4 ist miner1s block.

Miner2 hat, um wieder zu starten, weil in seinem block, er war mit dem vorherigen hash-Wert block3, jetzt hat er es ändern block4 hash.

Wenn ich einen Fehler gemacht haben, hinterlassen Sie bitte einen Kommentar, anstatt downvoting habe, würde ich gerne wissen, wo ich ging schief.
