Dies ist eine sehr offene Frage. Wenn Sie konzentrieren, könnte man wahrscheinlich besser Antworten. @Tarandeep-Gill, das ist richtig!!!! Der hash des vorherigen Blocks gehasht ist zusammen mit der Liste der Transaktionen. So etwas macht mich denken, dass meine Erklärung von hashing ist ein bisschen unvollständig -- Die spezifischen hash-Funktion ist nicht SHA256 doppelt angelegt wie angegeben, sondern eher, dass die Funktion angewendet, um verschiedene Teile des Blocks (einschließlich Transaktionen und das hash des vorherigen Blocks), die in verschiedenen Arten. Dies ist einer dieser "Ungenauigkeiten" vor dem ich gewarnt habe. Ich Frage mich, wenn Sie einen finden, die anderen...

Ich habe gelesen, dass es einige Variationen in: version, vorherigen block-hash, merkle root, Zeit, bits, und nonce

Das ist genau das richtige.

Manuell überprüfen, block-hash

(Dank an @exmachinalibertas) auf diesem reddit Kommentar

  1. Schnappen Sie sich ein block (zB. block 3): Block 3 im json - oder Block 3 in hex Verketten (in dieser Reihenfolge little-endian-hex-format) die version, vorherigen block-hash, merkle root, unix-Epoche, Zeit, Schwierigkeit Ziel (bits), und nonce. Sie werden sehen, können Sie die ersten 160 Zeichen aus dem Block 3 in hex-link. 01000000bddd99ccfda39da1b108ce1a5d70038d0a967bacb68b6b63065f626a0000000044f672226090d85db9a9f2fbfe5f0f9609b387af7be5b7fbb7a1767c831c9e995dbe6649ffff001d05e0ed6d

  2. Führen Sie den terminal-Befehl (unix):

    $ echo 01000000bddd99ccfda39da1b108ce1a5d70038d0a967bacb68b6b63065f626a0000000044f672226090d85db9a9f2fbfe5f0f9609b387af7be5b7fbb7a1767c831c9e995dbe6649ffff001d05e0ed6d | xxd -r -p | openssl sha -sha256 | xxd -r -p | openssl sha -sha256

Und es gibt die block-hash!

Ich würde gerne wissen, die genaue Zeichenfolge, ich kann in etwa wie folgt und genau dort, wo ich es finden kann

Dies wird wahrscheinlich nicht funktionieren, weil es aussieht wie es erwartet einen string, und es wird seltsam sein, zu versuchen, und konvertieren Sie die bytes im block-header in ASCII-Zeichen.

Hinweis: Sie müssen installieren Sie openssl zum terminal. Auch die xxd - Befehl konvertieren des hex-string in bytes, so wird der hash nicht den ASCII-bytes.
