这篇文章主要讲解了“Bytom信息上链的方法是什么”，文中的讲解内容简单清晰，易于学习与理解，下面请大家跟着小编的思路慢慢深入，一起来研究和学习“Bytom信息上链的方法是什么”吧！

很多了解比原链的都知道，比原链是专注信息和数字资产在链上交互和流转的公链项目，信息上链不是比原链核心能力，所以并没有在钱包端做一个功能入口，但是比原链提供了相关的接口可以将一些信息写到链上去。那如何实现信息上链呢？使用特殊的Retire操作，这个操作可以进行销毁资产的操作，但因为其可以附带信息，所以就可以实现信息上链的功能。

请往下看，也用postman请求演示，然后用golang写了一个接口的demo, 在用golang代码实现之前，我们先要做一些准备工作。

首先确保自己在本地已经搭建好了比原的节点

确保自己账户是有足够BTM测试币

发行自己的资产

信息上链的本质就是其实就是创建并发送一笔交易，我们都知道通过api发起交易主要有三个步骤，先 build → sign → submit，分别对应的api是 build-transaction、sign-transaction、submit-transaction。用postman请求过程如下：

请求build-transaction接口:

请求参数：

{"base_transaction":null,"actions":[{"account_id":"0KTCS3R5G0A02","amount":10000000,"asset_id":"ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff","type":"spend_account"},{"account_id":"0KTCS3R5G0A02","amount":100,"asset_id":"608037f96e8d1613d900c67a0730cc90e2a03311fb7d091588f7eb551a6103cd","type":"spend_account"},{"account_id":"0KTCS3R5G0A02","amount":100,"asset_id":"608037f96e8d1613d900c67a0730cc90e2a03311fb7d091588f7eb551a6103cd","arbitrary":"77656c636f6d65efbc8ce6aca2e8bf8ee69da5e588b0e58e9fe5ad90e4b896e7958c","type":"retire"}],"ttl":0,"time_range":1521625823}

请求sign-transaction接口：

请求参数：

用上面返回的tx_id去比原的浏览器中去查看交易详情，就可以查看到我们上传的数据
