{"index":1,"value":0,"address":null,"type":"op_return","multisig":null,"multisig_addresses":null,"script":"OP_RETURN 04fdfb5609aecb84f9f8f11f87bb1b7f9049805d3c6bee01d2199e99","script_hex":"6a1c04fdfb5609aecb84f9f8f11f87bb1b7f9049805d3c6bee01d2199e99","spent_hash":null,"spent_index":0}
Warum hat es für beide Felder "address" und "multisig_addresses" den Wert null? Was bedeutet "OP_RETURN" im Feld "Skript"?
Eine vollständige Erklärung von OPRETURN finden Sie hier: https://en.bitcoin.it/wiki/OP_RETURN
TLDR; OPRETURN ist eine "Daten-Push"-Ausgabe, die es ermöglicht, bis zu 80 Datenbytes in die Transaktion einzufügen, die sich auf die Transaktion auswirken.
Und der Wert für diese Ausgabe kann 0 sein.
Es wird unter anderem für verschiedene Dinge verwendet; Veröffentlichung von „Existenznachweis“-Hashes in den Blockchain- und Metaprotokollen.
Warum hat es für beide Felder "address" und "multisig_addresses" den Wert null?
denn den Programmierern von blockchain.info sind die Hände aus dem Arsch gewachsen
