這篇文章主要講解了“Bytom信息上鏈的方法是什么”，文中的講解內(nèi)容簡單清晰，易于學(xué)習(xí)與理解，下面請大家跟著小編的思路慢慢深入，一起來研究和學(xué)習(xí)“Bytom信息上鏈的方法是什么”吧！
很多了解比原鏈的都知道，比原鏈?zhǔn)菍Ｗ⑿畔⒑蛿?shù)字資產(chǎn)在鏈上交互和流轉(zhuǎn)的公鏈項(xiàng)目，信息上鏈不是比原鏈核心能力，所以并沒有在錢包端做一個功能入口，但是比原鏈提供了相關(guān)的接口可以將一些信息寫到鏈上去。 那如何實(shí)現(xiàn)信息上鏈呢？使用特殊的Retire操作，這個操作可以進(jìn)行銷毀資產(chǎn)的操作，但因?yàn)槠淇梢愿綆畔ⅲ跃涂梢詫?shí)現(xiàn)信息上鏈的功能。
請往下看，也用postman請求演示，然后用golang寫了一個接口的demo, 在用golang代碼實(shí)現(xiàn)之前，我們先要做一些準(zhǔn)備工作。
首先確保自己在本地已經(jīng)搭建好了比原的節(jié)點(diǎn)
確保自己賬戶是有足夠BTM測試幣
發(fā)行自己的資產(chǎn)
信息上鏈的本質(zhì)就是其實(shí)就是創(chuàng)建并發(fā)送一筆交易，我們都知道通過api發(fā)起交易主要有三個步驟，先 build → sign → submit，分別對應(yīng)的api是 build-transaction、sign-transaction、submit-transaction。用postman請求過程如下：
請求build-transaction接口:

用上面返回的tx_id去比原的瀏覽器中去查看交易詳情，就可以查看到我們上傳的數(shù)據(jù)
