在繼續研究腦<del>腦包</del>錢包的過程中 發現了這個精美的描述 私鑰->公鑰->WIF/Legacy Address 生成的實作圖解,如附圖,可以到這自己玩玩: http://royalforkblog.github.io/2014/08/11/graphical-address-generator/#noise 這也讓我意識到我之前理解的 https://noise.cash/post/l4ng2z75 0x04 前綴的部分是片面偏剖的。並不見得是一個固定的前綴,而是視縱座標的奇偶而定。(但在這網頁裡僅為 0x02 或 0x03,所以尚待分曉。) 補充:下面 @Ayukawayen 已經給出說明 https://noise.cash/post/l7n2p90v 這兩者都是對的,只是格式不同。這則的附圖是 compressed 壓縮公鑰格式,而另外一篇的是 uncompressed 未壓縮公鑰格式。可參考: https://ethereum.stackexchange.com/questions/103482/what-is-the-difference-between-compressed-and-uncompressed-public-key https://github.com/bitcoinbook/bitcoinbook/blob/develop/ch04.asciidoc#public-key-formats https://iancoleman.io/bitcoin-key-compression/
