Data Unavailability Unconference @Devcon4

Hi! I might be able to make the last couple of hours.

Is there a venue yet?

I would like to know more about the topic…if there is still space available.
The topic will also occupy us in our project.

@PhABC: Unfortunately, @sourabhniyogi and I won’t be able to make it on Oct 28th. We are arriving in Prague Oct 29th Midnight.

I (Jan Gorzny) am interested in attending - I am (and we at Quantstamp are) interested in researching the security and formal verification of many of these topics (and plasma and state channels in particular).

No problem. And 5~6 people going to be there with me.

Hey, thanks for organising but I cant make the 28th. You can take me off the list.

That’s unfortunate! Perhaps see you elsewhere :).

Cool! So long as there is a data availability component that would be interesting. I think it would be useful to have various examples with various assumptions about data availability.

Adding you to the list :).

Awesome! Yes, it’s almost 98% confirmed to be at this hotel, 2 mins away from the congress center.

Since we are close to capacity, please wait until the final count is in see if there is extra room. Thanks!

I’m sad to hear this. Hard to accommodate everyone unfortunately.

Added you!

Excellent. Also, since space is limited and we want to maximize benefits to the ecosystem, would it be possible to only bring 2-3 people from your team total? With only 30 places there isn’t room for many people. It’s possible we will have more room, but unclear at this point, so we prefer being conservative with the number of attendees.

Unfortunate to hear and thanks for letting us know.

I’ve been exploring solutions to the fair exchange problem where party A wants to atomically swap payment with party B for a verifiable digital good (i.e. some data that might’ve also transformed by some costly computation) - past research/literature includes zero-knowledge contingent payments and this post Fair exchange without a trusted third party. I can talk about some of the general ideas here, how this problem manifests specifically in the context of paying for something like video processing and what some promising directions for further exploration might be. This topic is a slightly different flavor of the data availability problem that is commonly discussed in the context of layer 2 scalability solutions, but it still exhibits some of the same types of headaches like speaker/listener fault equivalence so perhaps people would be up for discussing and maybe there is some overlap with the research on verification games that @nginnever is doing as well.


As @fraetz won’t make it, @pmizel can change places with him. Hope that’s fine.

Best regards,

Do we have an exact time for the gathering?

Not sure if I’ll be able to make it, don’t want to take up a space from someone. Sorry for the last minute notice.

@gluk64 We have the place from 1pm to 6pm, so what about starting around 13h30?

Perfect! See you soon

Will see everyone there. btw seems that my name appears twice.


so this is now on-going? Too bad it overlaps with Status hackathon and Council of Prague now at National House Smichov… would be super interesting to participate; I’m writing basically a payment channel that’s going to be “Plasma compatible” in terms of the root chain interface at least.

Here is our Presentation material.

Going great! Lots of good presentations.

Thanks all for coming! Was fun and interesting. Please paste your presentations below for those who want. Would be interesting to have some of the recordings as well, I know some people recorded some of the presentations.
