How to get the addr from this transaction

Question

https://www.blockchain.com/btc/tx/2ccc3f59d28c709770a8bc478b112e10feda4bf55197c2e48deaa0eb6bca0311?show_adv=true

The SCRIPT in the transaction is:

DUP HASH160 PUSHDATA(20)[482f0027662731277fdfa3b7f639c976a3bab11e] EQUALVERIFY CHECKSIG

What is 482f0027662731277fdfa3b7f639c976a3bab11e ?

It is not a pubKey. RIPEMD160(SHA256(482f0027662731277fdfa3b7f639c976a3bab11e)=146sN8tLxV2xueQXQgMJkMZi2hFazEuV8F.

The result is not the address(17afxUJouat3fkaaQ9tZrDThxdkXGL4WrM) in the blockchain.info either.

How we convert the 482f0027662731277fdfa3b7f639c976a3bab11e to it's addr？

Answer 1

482f0027662731277fdfa3b7f639c976a3bab11e is HASH160 (RIPEMD160(SHA256())) of the public key. The hash is the most important part of addresses (addres: network byte + hash + checksum).

You can look at how P2PKH script works step-by-step here.

Answer 3

Thanks for the answer here, the final code for the question is:

import hashlib
import base58 

def gen_addr(hash_code):
  key_hash = '00' + hash_code
  # Obtain signature:
  sha = hashlib.sha256()
  sha.update( bytearray.fromhex(key_hash) )
  checksum = sha.digest()
  sha = hashlib.sha256()
  sha.update(checksum)
  checksum = sha.hexdigest()[0:8]
  address = (base58.b58encode( bytes(bytearray.fromhex(key_hash + checksum)))).decode('utf-8')
  return address, key_hash, checksum

gen_addr('482f0027662731277fdfa3b7f639c976a3bab11e')='17afxUJouat3fkaaQ9tZrDThxdkXGL4WrM'
