Really nice to see BFT starting to be taken seriously in CRDT research. I had done some research in this area last year and came to a lot of the same solutions (i.e. BRB protected CRDTs when dealing with VClock based CRDTs):

We ended up moving away from VClock crdts entirely for our work and going with grow-only hash-graph CRDTs as they have don't need the BRB overhead (as Martin has found in his research as well).

I will stop looking into this now, I have to get back to my work. The colorful language doesn't make it easy for someone who follows the literature to review your idea.

I still have doubts that you can handle a dropped message or how much control a faulty node has over decisions, but I'll leave that to you to work out.

Ok, the red flag to me is the reliance on all neighbours responding to a proposal.

Suppose we have a faulty node heart-beating correctly but not responding to proposals, or selectively responding to proposals.

This would seem to imply that dishonest nodes have full control over which decisions are made.

> n ∈ N (p), where N (g) is the set of gnomes who can hear g, including himself. Note that h ∈ N (g) ⇐⇒ g ∈ N (h).

> Each gnome g tracks the spread of the proposal in the following way: once all his neighbors n ∈ N (g) say their k-neighborhood (or bigger) is aware of the proposal

If I understand this correctly, a single node crashing would stall it's entire neighbourhood. @gritzko, can you confirm?

That's Tue Dec 01 2020 23:53:04 UTC, consider this a heads up if that's when you started using signal.

Varies by business, for sure.

I'd say the chance is much higher for B2B businesses. Say my Shopify store fails so I cancel my subscription. But I'll likely come back and try my luck again with Shopify on my next idea since I've learned the platform.

These companies should realize they are playing an iterated prisoners dilemma game with their customers. Just because your services aren't right for me today, doesn't mean I won't come back in the future and pay for your services again now that I know what you do.

But I doubt I'd come back if my last experience with a company has been a bad cancellation procedure.

3% conversion on a product that costs $20k is normal? I don't think so.

As to your cynical meta-analysis, these people are doing something really difficult. I'm very happy to celebrate with them in any of their little victories, good on them! I hope to see more from them in the future

When writing that up I was looking for a structure who's natural partial order could be neatly laid out in 2-dimensions.

But it seems this is not very clear, I'll take another look around for a more intuitive structure.
