如何使用 pushpool 和 VARDIFF 設置層？（萊特幣）

我正在嘗試建立一個支持層協議和 VARDIFF（可變難度）的萊特幣挖礦池。

我在以下問題上閱讀了 cdecker 的答案How to setup pushpool。這很有幫助。我設法設置了 pushpool 並且一切都執行得很好（至少我可以看到 CGminer 連接並做某事）。

我只是堅持設置 startum 和 VARDIFF。我正在搜尋板，但找不到與我的問題相關的任何內容。我在 bitcointalk 上閱讀的唯一方法是使用"rpc.target.bits" : 18而不是"rpc.target.rewrite" : trueinserver.json來調整難度，但沒有成功 :( 對於 VARDIFF，我根本找不到任何東西。

任何幫助將不勝感激！

我回來為您發布所有資訊。

通過與 Stratum-mining 合作的最後幾個月，我得出了一些結論：你需要很好地了解 python 才能讓它在比特幣以外的任何東西上工作……話雖如此，它可以在目前的自定義 pushpool 安裝上安裝 Stratum通過我發布並正在研究的一個項目。（目前它適用於 freicoin，但您可以進行兩個微不足道的更改來讓我的實現在 litecoin 上執行）。還有另一個你可以使用的分層探勘實現，它最後一次更新是在 2013 年 6 月 6 日（如果你從頭開始安裝或目前使用 MMCFE，我建議使用這個而不是我的程式碼。我的程式碼版本被設計為對版本 2 的 getblocktemplate 更友好，因為萊特幣目前只支持 getblocktemplate 版本 1）。

將來區分這兩種實現可能非常有用，因為它們具有不同的數據庫模式……

同時，這裡是如何安裝stratum-mining-litecoion一個新系統或一個帶有MMCFE的系統

步驟 1) 備份您的數據庫 步驟 2) 備份您的數據庫 步驟 3) 備份您的數據庫

> 
> Step 3. Configure the Miner   cp conf/config_sample.py conf/config.py
>   make your changes to conf/config.py     Make sure you set the values in

> Step 4. Run the pool  twistd -ny launcher.tac -l -    OR - using

> 
> You can now set the URL on your stratum proxy (or miner that supports

> Database Setup
> ========================= Table Creation: Tables are auto-created if they don't exist (I will be adding a schema file later)

如果您已經在使用 pushpool 和自定義前端並且不想覆蓋您的系統，我有一個工作（但由於我的項目的性質，MBPM 有點錯誤）“安裝”版本的 freicoin 地層探勘可在此處獲取<https://bitbucket.org/joeswhite/joes-stratum-mining-freicoin/src/8eec8a0b11c6?at=master>

這是安裝我的版本的方法（除非您有編碼經驗，否則請勿安裝此版本！），萊特幣實施有一個附加步驟，但我尚未對其進行測試。

*litecoin specific step
At this point you need to go back and write over (at very least) the halfnode.py block_template.py and coinbasetx.py files with the files provided in stratum-mining-litecoion. most likely you will need to write over all of them. (This is the untested part i was talking about).

我正在嘗試在今天或明天進行實施，並且可以報告我當時需要進行的任何更改。

請讓我知道這是否是一個令人滿意的答案，如果不是。我會更新它，直到它是。謝謝你不抨擊我；）

您可能想嘗試這個版本的層：

<https://github.com/ahmedbodi/stratum-mining>

<https://github.com/ahmedbodi/stratum>

它帶有內置的萊特幣元件。此外，您可能希望考慮目前維護的池，因為根據比特幣 wiki 未維護 pushpool：

<https://en.bitcoin.it/wiki/Software>

如果您是初學者，我會推薦 P2Pool，如果您有更多經驗，請嘗試 Eloipool。
