| Outline of Final Research Achievements |
Blockchain (hereafter abbreviated as BC) has a problem of extremely low transaction processing performance. In order to improve this, we proposed a method for parallel transaction processing by managing BCs in each spatially divided domain and making them interoperable. We also proposed a chainless-type distributed consensus algorithm, which is different from the existing interoperable BCs. We theoretically showed that these proposed methods can improve not only transaction processing performance but also system safety.
There is a BC project to improve transaction processing performance by increasing block size. A theory on transaction processing performance and safety when block size is increased was considered.
We also proposed fact-checking DAO as an application of BC technology to counter disinformation.

| Academic Significance and Societal Importance of the Research Achievements |
既存の相互運用性を持つBCでは，リレーチェーンを用いて複数のBCを統合管理する共有セキュリティの仕組みを取っている．本研究では，リレーチェーンを用いずに共有セキュリティを強化するチェーンレス型相互運用モデルを提案した．これによりBCの相互運用性に関する新しい研究分野を開拓した．また取引処理性能とシステムの安全性を同時に改善可能なことを理論的に示した点において学術的意義がある．
BC技術の応用としてファクトチェック活動と関連する人材育成を暗号資産（ガバナンストークン）を活用した民主的な投票等によって運営するコミュニティを提案した．ファクトチェック活動の活性化が期待できる点において社会的意義がある．
