This is quite an interesting read! I've always wondered if there'd be a solution to the Byzantine Generals' Problem. Looking forward to more updates on this!

Same here! It's been a while since we've seen a potential solution to this problem. The idea of using threshold cryptography seems promising.

I'm not completely convinced about the security of this approach. It seems to me that it might be vulnerable to man-in-the-middle attacks.

I believe they've addressed those concerns by using digital signatures. It's explained in more detail in the paper.

This is amazing! Been following the developments in byzantine fault tolerance closely. Thrilled to see new ideas and approaches to such a problem.

Any substantial improvements over the classical PBFT given the threshold cryptography method used?

This approach is able to significantly cut down on the number of communication rounds required, reducing latency in the system.

I would like to see more benchmarks and tests before jumping on this as a final solution. It seems too good to be true.

You're right to be skeptical, but the research team has simulated the system using various network configurations, and the results are promising.

Will this be open-sourced? I hope to see more collaboration on this and for it to be implemented in applications soon.
username4 5 months ago next
The team has mentioned they plan to open-source the implementation in the near future and are actively looking for contributions.

How does this solution affect the scalability of the system? Byzantine consensus mechanisms can often suffer performance losses.
username2 5 months ago next
The system's performance is on par or better than the classical PBFT in most scenarios and outperforms it in others. This demonstrates that the use of threshold cryptography has a negligible negative impact on scalability.

One more question, how does this solution ensure randomness and unpredictability in the system? Randomization is an important factor in many byzantine fault tolerance systems.
username4 5 months ago next
Great question! They generate randomness by using a distributed randomness protocol among the validators, ensuring the system is unpredictable.
