由於操作流程較複雜,目前僅支援從桌面版進行 Arweave 的匯出與匯入操作。

行前準備

我們需要準備 2 樣東西:

  • Arweave 錢包
    • 如要申請官方發放的免費錢包,需要 Twitter 帳號
  • ArConnect 擴充套件

由於 Arweave 是應用區塊鏈技術的網絡,以合理的價格提供永久存儲。匯出到 Arweave 與從 Arweave 匯入都是此網絡上的一筆交易,需要支付手續費。因此,我們需要先取得 Arweave 的錢包,而且錢包內要有餘額,才能進行交易,存取鏈上的資料。

HackMD 不會直接保管或取得你的錢包資料,所以我們還需要安裝一個瀏覽器擴充套件 ArConnect。它就像是你的 Arweave 秘書,你將錢包的資訊交給這個套件,每當有網站(例如 HackMD)需要錢包的資訊,經你授權,網站就能取得完成交易(例如匯出或匯入筆記)所需的資料。

當然,取得 Arweave 錢包的方式不只下面介紹這一種,也有其他的方法可以管理錢包。不過 HackMD 目前只支援用 ArConnect 跟 Arweave 錢包互動。

完成這兩步驟後,就能輕易將你的 HackMD 筆記「上鏈」,讓所有人都能存取,但不能加以修改。

安裝 ArConnect

ArConnect 是瀏覽器擴充套件,常見的瀏覽器均有支援。請到 ArConnect 的官網,按 Download ArConnect,安裝擴充套件。

安裝後,我們會需要載入前一步取得的 Arweave 錢包。

ArConnect 載入錢包

  1. 安裝後,從瀏覽器開啟 ArConnect 擴充套件,如果未從使用過 ArConnect ,請點擊Get me started 並完成流程,你會獲得一串種子密碼,請務必記住它。

  2. 如果已經註冊過,請點擊 I have a wallet 輸入設定的密碼,接著輸入種子密碼,用來加密你的錢包。輸入後按 Next ->
  3. 裝備好擴充套件,並登入您的 Arweave 錢包。

匯出完成後,按【檢視分享頁面】,會開啟一個頁面,包含你剛才匯出的內容,以及本次上鏈交易的相關資訊。歡迎分享這個頁面。

注意事項

  • 匯出完成,表示 HackMD 已經將內容傳到 Arweave 鏈上,但還需要驗證交易等手續,需要一段時間才會完成上鏈,時間長短會因為匯出當時的交易量等因素而增減。
  • 如果想從 Arweave 鏈上取得內容,你會需要這筆交易的 Hash。在匯出成功的視窗連結到交易明細,或是在分享頁面上,都能取得這段 Hash。

從 Arweave 匯入 HackMD 筆記

  1. 從選單選擇從 Arweave 匯入:

交易 hash 要從哪裡取得呢?

  1. 在匯出成功的視窗,按下交易 hash,會帶您到 Viewblock.io 的頁面,檢視這筆交易的詳情:

    • The image was uploaded to a note which you don't have access to
    • The note which the image was originally uploaded to has been deleted
    Learn More →

    注意: 由於還需要完成驗證等手續,一筆交易才能真正「上鏈」,交易詳情可能會超過 10 分鐘後才能在 Viewblock.io 上看到。
  2. 從分享頁,文章結束處,有附上本次交易的 hash(本功能將於 11/15 前上線)。
  3. 從 ArConnect。每筆 ArConnect 經手的交易都會列在擴充套件視窗裡的 Transactions 頁籤:
