Detection and Prevention of Key-Compromise Related Fraudulence in Crypto-assets

This research paper presents a novel framework aimed at addressing key-leakage vulnerabilities in blockchain transactions, particularly in the context of crypto-assets. The framework utilizes blockchain technology and smart contracts to enhance transaction security while allowing users to define their desired security level through a mechanism known as the 'Trust Threshold.' This approach not only improves security but also reduces gas expenses, making it a cost-effective solution compared to existing methods. The paper provides a comprehensive analysis of the framework, emphasizing its dual focus on enhancing security and operational efficiency within blockchain networks. It also discusses the historical context of key-leakage incidents that have led to significant financial losses, underscoring the urgent need for improved protective strategies. The framework's effectiveness is validated through empirical evaluations, demonstrating its potential to strengthen the stability and reliability of blockchain systems. Overall, the paper contributes to the ongoing discourse on enhancing blockchain security and user autonomy in asset management.
