Title
(JA) ゼロ知識証明を用いたアカウント注釈モデルに基づくブロックチェーンデータの保護
Abstract
(JA)

本開示の実装形態は、第1のアカウントから、複数の注釈、複数の注釈の少なくとも一部分によって支払われる第1のアカウントと第2のアカウントとの間のトランザクションのトランザクション量のコミットメント、複数の注釈の合計値からトランザクション量を差し引くことによる変化のコミットメント、および1つまたは複数の選択された乱数に基づいて生成されるゼロ知識証明の、デジタル署名されたコピーを受信することを含む。第1のアカウントは、複数の注釈の合計値がトランザクション量および変化の合計に等しいと決定し、トランザクションを承認し、複数の注釈、トランザクション量、および変化に基づいて、第1のアカウントおよび第2のアカウントを更新する。
