On April 8, 2025, at the Web3 Scholar Summit, Professor Zhong Shao, Chair of the Yale University Computer Science Department and Co-Founder of CertiK, introduced the LiDO model and the LiDO-DAG extension framework. This innovative framework aims to address the security challenges posed by Byzantine Fault Tolerance (BFT) consensus protocols, a critical aspect of the Web3 ecosystem.

The LiDO framework is designed to provide mechanized verifiability of security and liveness proofs for complex BFT consensus protocols. It achieves this through a three-layered refinement verification framework: the security abstraction layer, the liveness assurance layer, and the DAG extension layer. This layered approach enhances the reliability and scalability of the Web3 ecosystem by ensuring that the protocols can withstand and recover from faults, thereby maintaining the integrity and performance of decentralized systems.

Professor Shao's presentation highlighted the successful application of the LiDO framework to industrial-grade protocols like Jolteon. The framework has been used to verify over tens of thousands of lines of Coq code, demonstrating its practical utility and robustness. This achievement underscores the potential of the LiDO framework to revolutionize the security and efficiency of BFT consensus protocols, paving the way for more secure and scalable Web3 applications.

The introduction of the LiDO framework at the Web3 Scholar Summit marks a significant milestone in the development of secure and reliable consensus mechanisms for decentralized systems. By addressing the challenges of BFT consensus, the LiDO framework offers a promising solution to enhance the overall security and performance of the Web3 ecosystem, making it a crucial development for the future of blockchain technology.
