# Kusamaverse Proposal
|
||||||
|
|
||||||
|
- Authors: {Péter Bertalan, Nagymarosi Máté, Toldi Balázs, Debreczeni Máté}
|
||||||
|
- Status: {Draft}
|
||||||
|
- Created: {2022-12-07}
|
||||||
|
|
||||||
|
## Summary
|
||||||
|
|
||||||
|
Our first proposal is to create more comprehensive learning materials, because we found the
|
||||||
|
UX clarity to be somewhat lacking. It shall convey the values and objectives of the platform
|
||||||
|
clearly. Kusamaverse needs to improve its authentication and authorization capabilities.
|
||||||
|
|
||||||
|
## Motivation
|
||||||
|
|
||||||
|
In our experience, Kusamaverse is hard to understand for new users. The user's first impressions are
|
||||||
|
important, but in the current version it is formed by marketing materials and forms. The user is not
|
||||||
|
presented with what the platform provides and how it can be used.
|
||||||
|
|
||||||
|
## Specification
|
||||||
|
|
||||||
|
proposed changes:
|
||||||
|
|
||||||
|
1. Game-like guided learning experience
|
||||||
|
|
||||||
|
2. Guide/Mascot character
|
||||||
|
|
||||||
|
3. Written materials, stories, and resources
|
||||||
|
|
||||||
|
4. The integration of authorization and authentication
|
||||||
|
|
||||||
|
### 1. Game-like guided learning experience
|
||||||
|
|
||||||
|
Most games start with a introductory quest, which eases the player into the in-game environment.
|
||||||
|
Kusamaverse would greatly benefit from such an addition. The user would receive valuable context
|
||||||
|
via a story told by an "in-game" character.
|
||||||
|
|
||||||
|
### 2. Guide/Mascot character
|
||||||
|
|
||||||
|
A fun mascot that could introduce the player to the Kusamaverse environment. It would always
|
||||||
|
be avaliable to offer guidance, especially during the first steps. Instead of forms, initial
|
||||||
|
user preferences could be attained through conversation with the mascot. The objective is to
|
||||||
|
make the process as fun as possible.
|
||||||
|
|
||||||
|
### 3. Written materials, stories, resources
|
||||||
|
|
||||||
|
Even after deliberate searching, information about the Kusamaverse was hard to find. For those
|
||||||
|
that are interested in the background, easily digestable materials should be made more avaliable.
|
||||||
|
|
||||||
|
### 4. The integration of authorization and authentication
|
||||||
|
|
||||||
|
To the best of our knowledge, currently there is no way to ensure that only select people can
|
||||||
|
attend a space. Collaboration can be enhanced by limiting unwanted access, which can degrade
|
||||||
|
the experience.

## Proposals
|
||||||
|
|
||||||
|
### 1. Kusamaverse
|
||||||
|
|
||||||
|
Our proposal focuses on usability and UX.
|
||||||
|
It can be found [here](./Kusamaverse_Proposal).
|
||||||
|
|
||||||
|
### 2. RMRK
|
||||||
|
|
||||||
|
We propose a few [improvements and enhancements ](./RMRK_Proposal) to
|
||||||
|
the ticketing sytem use case of RMRK.
|
||||||
|
|
||||||
|
## Main track: CCTF
|
||||||
|
|
||||||
|
We were presented with a vulnerable Capture The Flag
|
||||||
|
smart contract, which we fixed by the help of ZKPs.
|
||||||
|
|
||||||
|
Using ZKPs allows some unique features and it could
|
||||||
|
help provide the community with new and exciting
|
||||||
|
ways to organize CTF events. The solution can be found
|
||||||
|
[here](./CCTF_Solutions_main).

# RMRK Proposal
|
||||||
|
|
||||||
|
- Authors: {Péter Bertalan, Nagymarosi Máté, Toldi Balázs, Debreczeni Máté}
|
||||||
|
- Status: {Draft}
|
||||||
|
- Created: {2022-12-07}
|
||||||
|
|
||||||
|
## Summary
|
||||||
|
|
||||||
|
The RMRK documentation currently includes a use case description of a
|
||||||
|
ticketing system, built on revealable and multi-resource NFTs.
|
||||||
|
We extend this application with a few additional ideas that take
|
||||||
|
advantage of RMRK’s toolbox.
|
||||||
|
|
||||||
|
## Motivation
|
||||||
|
|
||||||
|
Classic solutions to ticketing come with their drawbacks. RMRK offers
|
||||||
|
new and versatile building blocks for making NFTs more powerful and
|
||||||
|
rich, while also eliminating a lot of the downsides. However, one aspect
|
||||||
|
not addressed by the current draft is scalping. Scalping is the practice
|
||||||
|
of buying large amounts of a scarce asset to resell it at a higher
|
||||||
|
price. Even centralized systems struggle to combat this issue. Our
|
||||||
|
proposal offers a possible mitigation.
|
||||||
|
|
||||||
|
## Specification
|
||||||
|
|
||||||
|
### Multi-use tickets
|
||||||
|
|
||||||
|
Instead of following the traditional scheme of one ticket per event, a
|
||||||
|
ticket could possibly be valid for a number of select or arbitrary
|
||||||
|
events. In this case, ticket validation would entail verifying a counter
|
||||||
|
or the presence of a specific PoA besides the secret keyword.
|
||||||
|
|
||||||
|
### A loyalty system
|
||||||
|
|
||||||
|
Dedicated fans deserve extra perks for their support. Our proposal
|
||||||
|
utilizes multi-resource NFTs to enable customers to attain a collection
|
||||||
|
of PoAs as part of a single NFT. This could be used to set up the basis
|
||||||
|
of a loyalty system. Owners of such collections would be able to
|
||||||
|
participate in presales, ensuring that they don’t miss out on their
|
||||||
|
favourite event.
|
||||||
|
|
||||||
|
### Scalping mitigation
|
||||||
|
|
||||||
|
The loyalty system outlined already offers some level of protection
|
||||||
|
against scalpers, but we would further enhance this with the use of
|
||||||
|
Verifiable Credentials. These could be issued by a trusted organization
|
||||||
|
and the amount of tickets per capita could be limited.
