本書の時点で、Cardanoには約30のネットワークパラメータがあります。これらのパラメータは、カルダノ・ブロックチェーンがどのように機能するかを制御するメカニズムである。今日は、最も古いパラメータの1つであるDecentralizationパラメータ、別名**「D」パラメータについてお話します。
では、何のためだったのか？
すべてのブロックチェーンは、数人の人がネットワークをオンにすることから始まります。その後、徐々に世界中の人がそのネットワークに参加できるようになります。 ブロックチェーン・ネットワーク上のコンピュータの仕事は、メッセージを処理し、誰もがルールを守っていることを確認することです。このコンピュータがネットワークを管理するのです。
Cardanoのようなパブリックパーミッションレスブロックチェーンでは、世界中の誰でも、どこでも、ブロックチェーンソフトウェアのコピーを実行し、自分のコンピュータをグローバルなCardanoネットワークにリンクすることができます。より多くのコンピュータが接続され、ネットワークに変更を加えるほど、ネットワークはより分散化されると言われています。
カルダノが最初に誰でもネットワークに参加できるように門戸を開いたとき、実は、ブロックの生成とも呼ばれる変更に参加できる人を制限していました。誰でもネットワークに参加できましたが、当初は創設者とあらかじめ選ばれたコンピューターだけがブロック生成に参加しました。
では、このように制御された中央集権的なシステムから、完全に分散化されたネットワークに移行したのはなぜか。ここで登場するのが「D」パラメータです。シェリー時代の2020年7月のローンチ以降、5日ごとにインサイダー対それ以外の人の比率が2％ずつ減っていった。インサイダーがブロックを生産することから、世界中のステークプール運営者に移行していったのである。
それから1年も経たない2021年3月31日、「d」パラメータは0に設定され、ブロック生産の検閲は一切行われなくなりました。これで、世界中の誰でも、自分のコンピュータをカルダノネットワークに追加して、ブロック生成に参加できるようになりました。
このことは2つの理由で興味深いです：
1つ目は、存在するすべてのブロックチェーンネットワークは、わずか数台のコンピュータから始まるということです。 一企業のサーバーから、強力な所有権と世界的なアクセス性を保証する検閲不能なデータストアを約束するパーミッションなしのパブリックブロックチェーンに成長させることは、大きな偉業だったのです。そのためには、コミュニティの幅広い賛同とグローバルな参加が必要でした。カルダノが1年足らずでこの目標を達成したことは、エキサイティングで印象的でした。
d’パラメータに関する2つ目の興味深い点は、パラメータが実際に変更できることです。つまり、カルダノの創設者たちは、パブリックなパーミッションレス・ネットワークBACKから、事前に承認されたサーバーだけがネットワークの状態を管理できるパーミッションド・ネットワークに変更することができたということです。
カルダノコミュニティにとって幸いなことに、2022年9月のヴァジルアップグレードイベントで、「d」パラメータは完全に削除されました。
自分の好きなブロックチェーンの起源を知ることで、その基盤や価値観を理解し、今後どのように成長し変化していくかを予測することができるかもしれません。
