can someone tell me how bitcoin hash a btc address?

when you try to hash it on this website, you will get the same result as down below

Bitcoin Address : 1JKRgG4F7k1b7PbAhQ7heEuV5aTJDpK9TS
Result (Hash 160) : bdf63990d6dc33d705b756e13dd135466c06b3b5

but when i convert the address to ripemd160, i got a completely different result

3da397753d32cea0858334e36fc58ae53f8c2529

so how do i get the same result as the first one?

To get the same result you must decode the address, which means convert the base58 to hexadecimal.

1JKRgG4F7k1b7PbAhQ7heEuV5aTJDpK9TS becomes 00bdf63990d6dc33d705b756e13dd135466c06b3b55850d39d

Where:

  • 00 -> mainnet
  • bdf63990d6dc33d705b756e13dd135466c06b3b5 -> hash160 of public key
  • 5850d39d -> checksum

  • Quite simple on this tool appdevtools.com/base58-encoder-decoder. You can also create an python file, import base58, then print(base58.b58decode(address).hex())
