Revolutionary governance model reshapes web 3.0 blockchain security

Researchers from Beijing Jiaotong University and Sun Yat-sen University unveil "TriGuard," an innovative governance mechanism that mitigates bribery in Delegated Proof-of-Stake (DPoS) blockchain systems. By leveraging a tripartite evolutionary game model, TriGuard enhances security, decentralization, and transparency in Web 3.0 governance. Published in Blockchain, this breakthrough ensures fair participation and robust security in blockchain networks.

Decentralized governance is a cornerstone of Web 3.0, offering transparency and empowering users with unprecedented control over digital ecosystems. Despite its transformative potential, the model faces critical vulnerabilities such as bribery and collusion, which threaten the fairness and integrity of Delegated Proof-of-Stake (DPoS) blockchain systems.

To address these challenges, researchers led by Jingyu Liu and Xingchen Sun from Beijing Jiaotong University, in collaboration with Sun Yat-sen University, have developed TriGuard, a groundbreaking governance mechanism. By integrating evolutionary game theory with tailored incentive structures, TriGuard ensures a fairer and more secure decision-making process within blockchain networks.

Jingyu Liu, lead author of the study, highlights the significance of this innovation: “Bribery undermines the foundational principles of decentralization. TriGuard provides a robust framework to counteract these threats, reinforcing the integrity of blockchain governance.”

TriGuard employs a tripartite evolutionary game model involving candidates, voters, and spontaneous supervisors. This model introduces balanced incentive mechanisms, encouraging honest participation while penalizing collusion and bribery. Extensive simulations demonstrate TriGuard’s efficacy, showing increased voter engagement, the elimination of malicious nodes, and resilience against high-intensity bribery attempts.

Co-author Xingchen Sun emphasizes the real-world impact of this innovation: “TriGuard realigns incentives within blockchain ecosystems, prioritizing decentralized governance. Its simulated success offers promising implications for broader applications.”

The research identifies key achievements, including the mitigation of bribery risks, enhanced stability under adverse conditions, and potential applications beyond blockchain governance, such as in decentralized autonomous organizations (DAOs). TriGuard’s development marks a pivotal advance toward realizing the decentralized vision of Web 3.0, laying a strong foundation for continued innovation in secure governance systems.
