Почему мой ha sh меняется с использованием Python Hashlib

Question

Я действительно застрял на этой проблеме в течение последнего дня. Кто-нибудь может мне помочь? Ниже приведен код:

import base64
import os
import datetime
import ast
from time import time
import hashlib, binascii

class BlockChain:
    def __init__(self, chain=[], difficulty=2):
        self.difficulty = difficulty
        self.chain = [self.createGenesis()]
        
    def createGenesis(self):
        return Block("sometext", datetime.datetime.now().timestamp(), 0)
    def latestblock(self):
        return self.chain[len(self.chain) - 1]
    def addblock(self, newblock):
        previouschain = self.chain
        rollbackchain = {}
        for i in previouschain:
            this = {i.index: {"data": i.data, "hash": i.hash,"previoushash": i.previoushash, "timestamp": i.timestamp, "index": i.index, "nonce": i.nonce}}
            rollbackchain.update(this) 
        open("previousChain.txt", "w+").write(str(rollbackchain))
        newblock.hash = newblock.mine(self.difficulty)
        newblock.previoushash = self.latestblock().hash
        self.chain.append(newblock)


    def verify(self):
        for i in range(1, len(self.chain)):
            current = self.chain[i]
            previous = self.chain[i - 1]
            if current.hash != current.calculatehash():
                print(current.hash + "<!=!!>" + current.calculatehash(True))
                print( Exception("current hash error"))
                #self.rollback()
                return False

            if current.previoushash != previous.calculatehash(True):
                print(current.previoushash + "<!=!!>" + previous.calculatehash(True))
                print(Exception("previous hash error"))
                #self.rollback()
                return False
                
            return True
    def rollback(self):
        n = 0
        prechain = ast.literal_eval(open("previousChain.txt", "r").read())
        for i in prechain:
            thisdata = prechain[i]
            self.chain[n] = Block(thisdata["data"], thisdata["timestamp"], thisdata["index"], thisdata["previoushash"])
            n += 1

class Block(BlockChain):
    def __init__(self, data, timestamp, index, previoushash="", nonce=0):
        self.data = data
        self.timestamp = timestamp
        self.index = index
        self.previoushash = previoushash
        self.nonce = nonce
        self.hash = self.calculatehash(True)
    def calculatehash(self, debbuger=False):
        byte = bytes(str(self.data) + str(self.timestamp) + str(self.index) + str(self.nonce) + str(self.previoushash), "utf-8")
        hashsha = hashlib.pbkdf2_hmac("sha512", byte, b'\xfe\x8f\x8d\xea\x8diM1u\xde\xe8)\xad<{\xe7\x83\xdcD\xa5\xb6\xf1\x98m\xf1\xea\xa8J\xb6j~w', 1, dklen=None).hex()
        if debugger:
            print("nonce",self.nonce)
            print("prehash",self.previoushash)
            print("index",self.index)
            print("time",self.timestamp)
            print("data",self.data)
            print("hash",hashsha == self.calculatehash())
            print("byte",byte)
        return hashsha
    def mine(self, difficulty):
        st = time()
        thishash = self.calculatehash()
        while not str(thishash).find("0" * difficulty) == 0:
            self.nonce += 1
            thishash = self.calculatehash()
            #print(self.nonce, end="\r")
        print("time took:", time() - st)
        return thishash #self.hash? self.hash = thishash?


chain = BlockChain(difficulty=2)
st = time()
print("mining block1...")
poopchain.addblock(Block("some transaction data", datetime.datetime.now().timestamp(), len(poopchain.chain)))
#print("overall time:", time() - st)
print("verifying")
print("ver",chain.verify())
for i in range(len(chain.chain)):
    print(poopchain.chain[i].__dict__)

Вот результат:

ha sh не то же самое, хотя байты такие. Я проверил ha sh, находятся ли они в одной и той же функции, и это так. Извините за длинный код, это для проекта цепочки блоков. Я использую hashlib binascii. Эти хэши не имеют к этому отношения, просто они не похожи. исследованы везде. спасибо, если помогаете!
