Blockchain-API zur Ermittlung von Transaktionsbestätigungen

Question

Ich versuche herauszufinden, ob eine Transaktion in der Bitcoin-Blockchain bestätigt wurde oder nicht. Ich habe eine JSON Darstellung der Transaktion von blockchain.info über diese URL zugegriffen: https://blockchain.info/tx/62f9419e56ac1b628840aaf52307867f9856d7a52b3c1d945a9938a3021cbf2c?show_adv=false&format=json

ich nichts in der Antwort finden können, wie viele Bestätigungen gibt es ...

Answer 1

hat das Konzept der "Bestätigung" auf Bitcoin übersetzt im Wesentlichen, wie viele Blöcke seit dem Block, der die Transaktion enthält, generiert wurden. Mit anderen Worten, Sie müssen eine weitere Anforderung stellen, um die aktuelle Netzwerkblockanzahl (http://blockchain.info/q/getblockcount) abzurufen, und die Bestätigungsanzahl wird dann current_block_count - transaction_block_height + 1. Beachten Sie, dass block_height nur in der Antwort vorhanden ist, wenn mindestens ein Block generiert wurde (d. H. Neue Transaktionen enthalten möglicherweise nicht einmal das Element).
