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：

{"password": "huangxinglong123","transaction": {        "allow_additional_actions": false,        "local": true,        "raw_transaction": "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",        "signing_instructions": [{                "position": 0,                "witness_components": [{                        "keys": [{                                "derivation_path": [                                        "0000002c",                                        "00000099",                                        "0100000000000000",                                        "0100000000000000",                                        "4600000000000000"                                ],                                "xpub": "1c03161a08a4dbb7df153815a28f733fec1ac7579f954c4834e5ce9f0ad8deb260ecb2066a8623b69aa936f5798f4dcb9572bc476f2c8171953ce054d58a759f"                        }],                        "quorum": 1,                        "signatures": null,                        "type": "raw_tx_signature"                }, {                        "type": "data",                        "value": "4f089176a5bca95ec9227b8a87dfec947c59453805bf46d3f5a18f8032255b5a"                }]        }, {                "position": 1,                "witness_components": [{                        "keys": [{                                "derivation_path": [                                        "0000002c",                                        "00000099",                                        "0100000000000000",                                        "0100000000000000",                                        "4700000000000000"                                ],                                "xpub": "1c03161a08a4dbb7df153815a28f733fec1ac7579f954c4834e5ce9f0ad8deb260ecb2066a8623b69aa936f5798f4dcb9572bc476f2c8171953ce054d58a759f"                        }],                        "quorum": 1,                        "signatures": null,                        "type": "raw_tx_signature"                }, {                        "type": "data",                        "value": "67512f9250f559699e32c72c8af29096b1556af145f6ecc0c306e6acc88bbfaa"                }]        }]}}

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
