如何將 pyethapp（python 乙太坊客戶端）與主網同步？

  • April 5, 2018

我剛剛安裝了pyethapp。但是，我無法同步區塊鏈。這是我執行客戶端時得到的結果：

0 ✓ user@host ~ $ pyethapp run

Failed to import scrypt. This is not a fatal error but does
mean that you cannot create or decrypt privkey jsons that use
scrypt

如何將 pyethapp（python 乙太坊客戶端）與主網同步？

更新，我只是想，我可能必須添加一個引導節點。由於我已經在 localhost 上執行了 parity、geth 和 eth，因此我將它們添加為帶有 的引導節點-b，但是我收到以下錯誤：

Traceback (most recent call last):

<Peer('127.0.0.1', 37178) > failed with AssertionError

這是一個錯誤嗎？

答案是耐心。pyethapp 與其說是生產就緒節點，不如說是概念驗證實現。

我不得不等待幾個小時，直到我注意到客戶端開始同步主網路。幾天來，它的同步速度非常緩慢，而且我的磁碟上只有前一百萬個塊。繼續等待其餘的。

TL;DR pyethapp 有效，但如果你想在主網上工作，請準備一些時間。

萬一有人像我一樣現在（問題發布兩年後）發現了這一點：在嘗試修復在主網上執行 pyethapp 的各種問題後，我從 wiki 仔細查看了這個頁面。這意味著 pyethapp 目前無法在主網上執行，或者至少在 2017 年 3 月沒有。
