我在我的私人乙太坊區塊鏈中遇到了這個問題（節點未同步，節點數據寫入錯誤，同步失敗，重試）

December 20, 2019

我是乙太坊的新手，現在使用 geth 獲得乙太坊區塊鏈

geth –port 3000 –networkid 58342 –rpc –rpcport 8545 –rpcaddr 10.0.0.2 –rpccorsdomain “*” 控制台

嘗試將 geth –testnet 用於 ropsten 測試網，同步需要幾個小時或幾天，具體取決於您的連接。否則，如果您想要主鏈的警察，您可以使用 geth –light 這將為您提供區塊鏈的輕度同步，從而允許您與主網進行互動。–light 的同步時間應該只有大約 5-10 分鐘。您可以通過打開一個新終端並使用 geth –attach 進行輕同步或使用 geth –testnet attach 進行 ropsten 來檢查同步百分比。這將允許您使用“eth.syncing”檢查同步狀態，然後您可以將您目前的塊大小與 etherscan 或 ether chain.org 進行比較。
還有其他選項可以讓節點在您的機器上執行，例如 testrpc、ganache-cli，但這些只是代表乙太坊區塊鏈的本地節點。
