前幾天心血來(lái)潮，用Java模擬實(shí)現(xiàn)了一個(gè)區(qū)塊鏈小工具，該工具是單機(jī)版的，沒(méi)有實(shí)現(xiàn)聯(lián)網(wǎng)功能，屬于是單節(jié)點(diǎn)的工具，但是對(duì)于區(qū)塊鏈的核心wk邏輯功能都實(shí)現(xiàn)了，如：wk、錢(qián)包、轉(zhuǎn)賬、記賬等功能。界面實(shí)現(xiàn)用到了Java的swing包。

下面先看下運(yùn)行的效果：

主界面：

轉(zhuǎn)賬：

?下面來(lái)看看代碼：

首先是界面：文章來(lái)源地址http://www.zghlxwxcb.cn/news/detail-508776.html
