[IMPACT] Please describe your proposed solution.

Our proposed solution tackles the problem of having centralized API services by introducing a novel decentralized system architecture. By using state channels for request-response operations and implementing a reward system for load distribution among servers, we aim to enhance resilience and encourage organizations to participate by running their servers.

In our decentralized system, API calls are managed through (DRED) state channels, enabling reliable tracking and management of request and responses. The introduction of a decentralized load balancer dynamically offers responsibility for serving API calls to specific servers managed by node operators (such as DAO members).

This unique solution for load distribution balances workload across the network to provide resilience, while having a decentralized consensus record of the contributions provided by servers.

We aim to engage node operators who may have spare capacity on underutilized hardware, and with developers on projects who can benefit operationally by using decentralized API services. Developers will also benefit by being able to write traditional API code (e.g. an express web server) and deploy decentrally.

We will develop code and documentation developers can use to understand how to get the advantages of decentralized APIs and most effectively integrate them into their applications.

In future, our solution will also be able to incentivize operators to participate in the network and maintain their servers, rewarding them for successfully serving API calls. This fosters a healthy and robust decentralized API service ecosystem, driving the shift to decentralized systems.

[IMPACT] How does your proposed solution address the challenge and what benefits will this bring to the Cardano ecosystem?

Our solution directly addresses the Development & Infrastructure challenge by providing a decentralized RPC/API service enabling a shift to decentralization. Benefits include improving security, resilience, and fair distribution of rewards, and attracting a broader audience to Cardano.

This will attract developers and enable authors of traditional API's to continue using their skills and code, and to operate those APIs through decentralized, community-operated infrastructure

Other secondary benefits include increased developer engagement, and fostering innovation by enabling innovative applications.

[IMPACT] How do you intend to measure the success of your project?

We’ll measure the success of our project through several key metrics demonstrating its positive impact on the Cardano ecosystem. Our primary objective is to streamline the integration of at least one existing service with our decentralized APIs, such as Dandelion/GraphQL and Demu Munode. Additionally, we will closely monitor the adoption rate of our DRED decentralized API among applications, as well as the growth in the number of developers utilizing our solution. A substantial increase in both application usage and developer engagement would serve as strong indicators of the project's success.

Moreover, we recognize the importance of qualitative feedback, and thus, we plan to conduct user feedback sessions to gather valuable insights and assessments regarding the usability and effectiveness of our decentralized APIs.

Concluding, our ultimate goal is to foster innovation within the Cardano ecosystem by enabling the utilization of the Node operator model for different services. Consequently, it is crucial to monitor robustness indicators, such as resilience, security, and censorship resistance.

[IMPACT] Please describe your plans to share the outputs and results of your project?

We will actively engage with the community by making regular commits to our open-source repository and incorporating user feedback to enhance the project. Updates on our progress will be shared through platforms like Twitter, Discord, and also in After Town Halls. Once completed, the project will be publicly available on GitHub.

Collaboration with Cardano’s developer community is a priority for us. Consequently, we will organize workshops and webinars to share knowledge, discuss our solutions, and encourage further research and development for decentralized APIs

The project’s output will be valuable for future R&D. The documentation and codebase will serve as a guide for developers working on Cardano-related services switching to the Node operator model, while node operators with spare capacity can benefit from our work (e.g. being incentivized to serve API calls for other decentralized services).

[CAPABILITY/ FEASIBILITY] What is your capability to deliver your project with high levels of trust and accountability?

We’re confident in our ability to deliver this project with high levels of trust and accountability, based on our demonstrated capabilities. For instance, we have successfully managed funds responsible and delivered the DRED project, despite encountering challenges and dependencies on the CAD poker proposal. Additionally, even in the face of declining ADA values, we have thoroughly explored the Kaleidoscope paper and collaborated with Catalyst to design and code essential components for the related protocol. These accomplishments highlight our reliability and competence in managing funds effectively.

[CAPABILITY/ FEASIBILITY] What are the main goals for the project and how will you validate if your approach is feasible?

The main goals are:

• Create a way to run a traditional API service in a decentralized way
• Provide web/javascript client software bridging to the service network
• Provide documentation on "How to decentralize a traditional API" with this protocol
• Update existing CIP draft from DRED to cover this use case
• Capture contribution-accounting information
• Stretch: rewards model

Because most of the research and development efforts with DRED have been completed by the same team, we don't see any significant feasibility risk. Our work-planning front-loads key technical development to the first milestone, so that we can get prompt feedback and decide how to respond to any discovered challenges.

We will validate our approach's feasibility through incremental testing of DRED integration and transitioning of an existing Cardano centralized API service into a decentralized one, and by getting feedback from the community sessions.
