Address-Generation
在大腦錢包上重複 sha256
本文作者<https://pastebin.com/raw/jCDFcESz>解釋說
Sha256('sender') x 2
產生地址18aMGf2AxQ3YXyNv9sKxiHYCXcBJeJv9d1
但是我得到了地址
1DcTtaa37w971TmoafPpE9Pk16xc42YA87
我究竟做錯了什麼?
需要檢查的幾件事:
確保您正在計算
HASH256
字元串的解碼字節值。換一種說法,HASH256(0x73656e646572)
確保你正在做 2 輪
SHA256
使用 secp256k1 生成壓縮公鑰
這是一個
P2PKH
地址(前綴為 1),因此從公鑰生成地址的步驟是:
pubkeyhash = HASH160(compressed pubkey)
IERIPEMD160(SHA256(compressed pubkey)
為
00
_P2PKH
BASE58CHECK(pubkeyhash)
