geth 1.9.1アップデート

Posted at

infura.ioが課金を初めて阿鼻叫喚のみなさまこんにちわ。
ほぼ電気代ぐらいの金額ってのは救いですね。

7/24に1.9.1がリリースされたのでアップデートメモです。
https://github.com/ethereum/go-ethereum/releases

今回は1.9.0から1.9.1にアップデートしませう。

TL;DR

すんなりアップデートできてしまったので、今回追加されたeth_getHeaderByNumber and eth_getHeaderByHashを試しています。

すんなり起動してしまいました。

今回追加されたeth_getHeaderByNumber and eth_getHeaderByHashを試してみましょうか。lightクライアントモードでヘッダーをピアに取りに行っていたのが無駄じゃないかということで追加されたものみたいです。

attachしてeth.getHeaderByHashで適当なブロックヘッダーを見てみます。
