Minecraft Watcher

Periodically checks a Minecraft server for changes in online players, logs those changes, and sends desktop notifications (using libnotify) for those changes.

Setup

The following setup assumes python-gobject (Python 3) is installed by your package manager. This dependency can be satisified by pip install PyGObject from within the venv, but compile issues might occur (and is outside the scope of this article).

MonacoinprojectはASICを否定しません。
ASICは消費電力、ネットハッシュの確保（＝攻撃コストの増加）という点で有効です。
（同じようなことを2014年にもどこかで書いた記憶が・・・）

先のアルゴリズム変更は遅延を解消することが目的で、"結果的"にscrypt-ASICが使えなくなったという事です。
もっとも当時のscryptはSHA256に次ぐ採用率の高いアルゴリズムであったので、他のコインへの流用は十分可能だったと思います。

将来的にLyra2REv2でも遅延・寡占が問題になった場合はアルゴリズムの変更が検討されるでしょう。
ASICの首を絞めるのはASICによって遅延を引き起こす一部のユーザーにあります。
逆に遅延も無く、高いネットハッシュが安定して続くのであればアルゴリズムの変更はありません。
