CAGA, a Card Game App Framework

[IMPACT]

Our solution consists of providing a reusable application comprising

• a flexible Javascript frontend
• a protocol, based on Kaleidoscope, to enable establishing connection among players
• a smart contract to enable players to sit at table and lock funds (collateral + bet amount)
• an application backend connecting to a Cardano node and integrated with a wallet
• extensive documentation and howtos to understand how to modify

The reusable application is made of two layers: a reusable platform (CAGA framework) and a concrete application (Cardano After Dark).

The framework shall be reused by other developers to quickly startup their Card-Game projects.

The CAGA Framework should be used by other projects interested in building card game applications in two directions:

• (Users) Increase the number of Gaming Dapps available on the ecosystem
• (Contributors) extend the framework and build a community around the framework

The main risk is the absence of a clear solution for a state channel, that is needed to have fast response time and no fees during the phases in which the users are interacting with each other.

a way to de-risk is consider different solutions for scalability, incl. hydra, redis, & c.

A secondary risk is related to expenses for legal and learning. Given the project budget is small, a fluctuation of any of the previous two might affect the project budget

a way to de-risk is to gradually release the project funds, after legal and learning expenses are paid.

[FEASIBILITY]

November 2022: Project available for download, together with documentation

the main items of expenditure are

• javascript and frontend development: 200 h * 50 $ = 10,000 $
• plutus and backend development : 200 h * 50 $ = 10,000 $
• legal advice: (estimated) 10,000 $
• project management, meetings, and resource finding 150h * 50$ 15,000 $
• documentation: 50 h * 50 $ = 2,500 $
• community, learning, and partners = 7,500 $

A grand total should be around 55,000 $

[AUDITABILITY]

The application framework should be available in November

The framework should have proper documentation, including: how to build, how to run, how to customize.

There should be a sample application built with the framework. Such application should be easy to customize

The framework is used by one or more projects for bootstrapping their Gaming application

The framework should get contributions from other teams who are interested in increasing the overall quality of the component.

Yes, this proposal is a continuation of F7: Cardano After Dark; with more oomph, experience, and desire to share the knowledge and components that we developed.

With this follow-up proposal, we are going to address further problems, such as:

• split the application in two parts
• a generic framework that should be reused and improved over time (open source)
• a business-case specific application (core business, already covered by prev. proposal)
• need for a state channel
• need for legal advice related to deploying card games.
• need to produce examples that can be reused by the community
