這篇文章主要講解了“Bytom信息上鏈的方法是什么”,文中的講解內容簡單清晰,易于學習與理解,下面請大家跟著小編的思路慢慢深入,一起來研究和學習“Bytom信息上鏈的方法是什么”吧!
很多了解比原鏈的都知道,比原鏈是專注信息和數字資產在鏈上交互和流轉的公鏈項目,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的接口可以將一些信息寫到鏈上去。 那如何實現信息上鏈呢?使用特殊的Retire操作,這個操作可以進行銷毀資產的操作,但因為其可以附帶信息,所以就可以實現信息上鏈的功能。
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代碼實現之前,我們先要做一些準備工作。
首先確保自己在本地已經搭建好了比原的節點
確保自己賬戶是有足夠BTM測試幣
發行自己的資產
信息上鏈的本質就是其實就是創建并發送一筆交易,我們都知道通過api發起交易主要有三個步驟,先 build → sign → submit,分別對應的api是 build-transaction、sign-transaction、submit-transaction。用postman請求過程如下:
請求build-transaction接口:
請求參數:
{ "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 }
請求sign-transaction接口:
請求參數:
{ "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去比原的瀏覽器中去查看交易詳情,就可以查看到我們上傳的數據
