Since the inception of blockchain in 2008, it
has played a crucial role in cryptography. In recent years, its applications
have expanded beyond cryptography, evolving into a comprehensive information
technology framework across various fields. Traditionally, the security of
digital signatures has relied on the assumption of computational parity between
attackers and defenders—that is, both parties possess equal computing power.
However, this assumption inherently carries the risk of a significant disparity
between offense and defense. Users must remain vigilant against potential
attacks from counterfeiters impersonating decrypted users.
In
this study, we propose a feasible Fail-Stop Scheme (FSS) technology to address
this issue, providing a more robust framework to enhance blockchain security.
