Title: Segwit address generation Post by: nofiat on December 15, 2017, 11:03:48 PM Hi,
I'm trying to figure out how to create a Segwit address. I already managed to create an original bitcoin address. Let's assume the following Public Key: publicKey = 03fac6879502c4c939cfaadc45999c7ed7366203ad523ab83ad5502c71621a85bb *ripemd160(sha256(publicKey)) = 7646c030f7e75b80f0a31cdcab731e6f424f22b2 - hash *Add version to hash = 00147646c030f7e75b80f0a31cdcab731e6f424f22b2 - redeemScript *ripemd160(sha256(redeemScript)) = 188ba16284702258959d8bb63bb9a5d979b57875 - hash *sha256(sha256(redeemScript)) = 55c304447c41caee29f1d7c9779a3a8e9dd00ea7905e286e733049d12e1b479f - hash-for-checksum --so far so good (I assume)-- *4 byte checksum = 55c30444 - checksum *'05' + hash + checksum = 05188ba16284702258959d8bb63bb9a5d979b5787555c30444 - this is the part I get wrong I think *base58 of it = 33voQqbNAYyig272KjcX8GkucWn2uJk5WT - this is the address that I get, while I should be getting 33voQqbNAYyig272KjcX8GkucWn2x25WEg. How is possible that only the last 6 characters are incorrect? Does that imply that the checksum is incorrect? Or when it comes to segwit, is the base58 function different?
