載入檢查點時出現分段錯誤 - altcoin dev

我試圖複製比特幣的原始碼並執行一個全新的區塊鏈。我成功地改變了初始參數，例如

• psz時間戳
• 時間
• nNounce

生成了一個創世塊並替換了硬編碼的值

• 共識.hashGenesisBlock
• genesis.hashMerkleRoot

以上步驟成功生成了創世塊。但之後比特幣核心試圖從磁碟載入檢查點（我認為是這樣）並導致錯誤。

有一個執行緒解釋瞭如何阻止程式碼檢查檢查點。<https://bitcointalk.org/index.php?topic=225690.0>但是執行緒已經過時並且程式碼經歷了很多變化。

我需要一些幫助來解決錯誤並繼續安裝前幾個塊並將它們也硬編碼到程式碼中。

嘗試刪除塊文件。該錯誤表明已載入塊上的工作證明不正確。

還要檢查檢查點，也許這會有所幫助！
