In this presentation, he proposed the "WARASHIBE Protocol" to achieve fair data-for-data exchange on the blockchain. This research introduces a new concept of "Financial Fairness" to the challenge of atomic data exchange on blockchains, and designs a protocol that prevents financial loss for honest participants even when malicious participants are present. The proposed method succeeds in reducing computational costs by 20% compared to conventional methods.

We will continue to make every effort to advance our research activities, and we look forward to your continued warm support.
