# 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.
