Please describe your proposed solution

As there are no real-time applications in Cardano, we’re going to integrate DRED real-time messaging capabilities into an existing application, and create technical resources for other application developers to learn how to add real time communications to their dApps.

Integrating cPoker with DRED, we will demonstrate that more secure, scalable, and interactive applications can be built on Cardano. We will also interact with the developer community to share information and ensure that the approach and messaging of our technical resources is fitting to the audience.

We will further develop the DRED node-to-node state-replication capabilities, fulfilling DRED's potential to operate in full decentralized fashion - different poker-game clients can connect to different DRED nodes in the poker neighborhood. The code and the process of making the changes will be shared with the community as Open Source.

We will update the poker-game demo to create and share transaction data for the in-game state, demonstrating the use of DRED as a transaction state channel for multi-user smart contracts.

Our project will primarily engage developers in the community and potential dApp users. Our impact will be visible in having a working poker demo-dApp, and in the the number of developers attending sessions, improved documentation, and enhanced functionality of cPoker.

Please define the positive impact your project will have on the wider Cardano community

Our solution develops an example with an enhanced infrastructure, which allows for real-time interaction between dApps. Here is how we positively impact the community:

• Learning Environment: Aimed to engage 20+ developers through interactive demo sessions and detailed documentation.
• Real-time Communication: Expected to reduce latency in multi-user dApps by 50%, enhancing user experience.
• DRED Enhancement: Projected to increase the adoption of DRED by at least 3 new dApps within the first year.
• Off-chain Transactions: Demonstrating a 30% improvement in transaction speed and efficiency in the cPoker application.
• Documentation: Publishing 5 detailed tutorials and hosting 3 webinars to educate the community.

What is your capability to deliver your project with high levels of trust and accountability? How do you intend to validate if your approach is feasible?

Our capability to deliver can be demonstrated by what we have already done, what we are doing, how we are working together, and by the reputation of the team members:

• we developed DRED, a foundational library at the core of this proposal. The DRED project was managed and successfully delivered by this same team.
• we are developing a commercial gaming application using DRED, of which we have a working PoC. The example that we create with this proposal is simpler version of that application.
• the team is capable, meets regularly, and has a good track record of github commits, and of published documentation and videos for the current projects
• several team members are well-known in the community

The feasibility of our approach is validated according to our past accomplishments

• Research phase completed
• Incremental progress: we broke down the problem in subproblems, which makes it easier to solve different aspects:
• Cardano After Dark for Poker UI
• DRED to implement a State channel
• zkpoker: to enable zk-proof of validity
• and our latest PoC demonstrating we can run a poker protocol with encrypted cards.
• Pragmatic approach: incremental testing during development, incremental assessment of the deliverables for the project milestones
• Feedback loop from community sessions and from users.
