Moneroのマイニング状況を確認しようと supportXMR.com を開いたら、ページの一番上に見たことないこんなのが書いてあった。
Google翻訳によるとAttention MinersUpdate your Mining Software until 2018-10-18 to get ready for the upcoming protocol upgrade. If you neglect to update to a v8 capable mining software and/or proxy, you will no longer be able to mine after block 1685555.
v8対応とかブロック1685555とかよくわからないが、「Moneroがハードフォークするから、2018-10-18までにマイニングソフトも新しいものにしてね」ということだろう。注意鉱夫今後のプロトコルのアップグレードを準備するために、2018-10-18まで鉱業ソフトウェアを更新してください。 v8対応のマイニングソフトウェアやプロキシにアップデートするのを怠った場合、ブロック1685555の後でマイニングすることはできなくなります。
今が2018-10-14で、とりあえず2018-10-18まで時間があるから様子をみよう。
2018-10-15追記
Moneroがハードフォークでどう変わるか
Moneroの公式サイトをGoogle翻訳で読んでみたが、庶民には内容が難しくてよくわからなかった。後学のために残しておくが、今回のハードフォークでMoneroは以下のとおり変わるそうだ。以下Moneroの公式サイトより抜粋概要
This is the v0.13.0 release of the Monero software. This major release is due to the October 18th network update, which in turn enabled Bulletproofs for reduced transaction sizes, sets the ringsize globally to 11 for uniformity of transactions, updated the PoW algorithm to CNv2, and finally sets the max transaction size at half of the penalty free block size. This release of the software presents a number of major improvements to Monero, as well as a large set of bug fixes.変更点の抜粋
