I am a beginner in python I want to transfer generated hash to a local
database. I try it with socket programming but I fail. can anyone please help
me ow I can do this?
class Block:
def __init__( self, previous_block_hash, transaction_list ):
self.previous_block_hash = previous_block_hash
self.transaction_list = transaction_list
self.block_data = f"{' - '.join(transaction_list)} -
{previous_block_hash}"
self.block_hash = hashlib.sha256(self.block_data.encode()).hexdigest()
class Blockchain:
def __init__( self ):
self.chain = [ ]
self.generate_genesis_block()
def generate_genesis_block( self ):
self.chain.append(Block("0", [ 'Genesis Block' ]))
def create_block_from_transaction( self, transaction_list ):
previous_block_hash = self.last_block.block_hash
self.chain.append(Block(previous_block_hash, transaction_list))
def display_chain( self ):
for i in range(len(self.chain)):
print(f"Hash {i + 1}: {self.chain [ i ].block_hash}\n")
@property
def last_block( self ):
return self.chain [ -1 ]
**t1 = Time_sensitive_df
t2 = "abcdefghijklmnopqrstuvwxyz"
t3 = normal_df
myblockchain = Blockchain()
myblockchain.create_block_from_transaction(t1)
myblockchain.create_block_from_transaction(t2)
myblockchain.create_block_from_transaction(t3)
myblockchain.display_chain()**
