ビットコインSegwit2×ハードフォーク

こんにちは、@マナです。

ビットコインSegwit2×ハードフォークのニュースをシェアしときますね。
香港の仮想通貨取引所の1つGatecoinは、Segwit2×のビットコイン(B2X)をサポートしないと発表しました。

【公式の元記事】Gatecoin will not support the SegWit2x (B2X) hard fork

主な内容は下記の通り。

  • B2Xをクライアントに配布しない
  • Bitcoin Walletアドレスに送信されたB2Xを処理しない
  • 取引所にB2Xビットコインを載せない

つまり、11月19日に起こる予定のハードフォークで生み出されるビットコインは、ビットコイン保有者に配布もしないし取引所で扱うことも無い、という発表です。

他には中国大手マイナーのF2PoolもSegwit2×のハードフォークを支持しないと、10月12日に発表。

他にも続々と、支持しない事を表明している仮想通貨事業者が増加中。

そんな中、11月13日にビットコインキャッシュもハードフォーク。

Segwit2×のハードフォークとは全く関係ないハードフォークで、どうやら難易度調整アルゴリズム絡みのようですね。

今のビットコインキャッシュの採掘難易度は、ビットコインが難しくなれば易しくなるようなアルゴリズムで設定されているらしい。
ビットコインマイナーは基本的に儲かるものをマイニングするので、このハードフォークが今後どう影響するかは未知ですね。

さて、10月25日以降、どうなるか見ものですね。
