Value For Money

The introduction of Koios Lite aims to facilitate broader community participation and reinforce decentralization. Considering its open-source commitment and its potential to amplify community tools, the project presents a cost-effective proposition for the Cardano ecosystem.

Now, Let’s Dive into the Details

What problem is this project solving?

Cardano’s infrastructure is currently grappling with issues of centralization, where limited projects act as primary channels for blockchain data access and processing. This centralized framework creates a bottleneck, making it less robust and user-friendly.

Specifically, there’s a growing demand to:

  • Run lightweight instances that consume fewer resources.
  • Adapt to the increasing need for querying data as the ecosystem evolves with new projects.
  • Maintain a stable infrastructure that offers multiple public instances across networks, especially until certain tools become self-sustainable.
  • Provide support across a range of open-source projects and tools to ensure smooth user experiences.
  • Integrate with AI platforms, which requires a seamless and educative interface for newcomers to engage with on-chain data.

These concerns highlight the current infrastructure’s inability to scale efficiently and inclusively, making it imperative to address them for Cardano’s sustainable growth.

What is the solution offered by the project to solve the above mentioned problem?

The Koios proposal aims to tackle these challenges through:

1. Koios Lite: This feature aims to make Cardano more accessible. 

The impact of Koios Lite can be seen in the following areas:

Accessibility: By offering a lighter way to run an instance, Koios Lite allows more providers to participate, potentially broadening the reach of the Cardano network and making it more accessible to various users and developers.

Resource Efficiency: The light-resource nature of Koios Lite provides a more cost-effective option for querying data from the chain, helping to onboard new instance providers and cater to different needs and resources.

Decentralization: By enabling a wider range of participants to host instances, Koios Lite contributes to the decentralization of the Cardano infrastructure, aligning with the overarching goal of creating a more distributed and resilient network.

Koios Lite’s provision of a historical view of the chain enhances the understanding and analysis of blockchain data, enabling more insightful applications and services within the Cardano ecosystem.

2. Ongoing Development Activities on gRest: The constant improvements on gRest ensure that the infrastructure remains responsive and innovative. This ongoing development is key to meeting the evolving needs of the Cardano ecosystem, keeping it aligned with technological advancements.

3. Maintaining Support for Cardano Infrastructure with Open-Source & Elastic API Layer: Koios’s API allows querying across Cardano’s blockchain, providing a vital layer of flexibility. Whether using Koios as a light web service or running an extendable instance, it ensures high availability support globally. This is a strategic move towards a more decentralized and resilient infrastructure that can adapt to various demands.

4. Integration of AI Plugins: By integrating with AI Plugins and powering real-time blockchain data, Koios helps bridge the gap between AI and blockchain technology. This not only enhances Cardano’s reachability in the AI world but also simplifies the learning curve for new entrants, making the ecosystem more inviting.

5. Support for Open-Source Projects and Tools: Koios has been providing extensive support across different projects, particularly those that are open-source and free. This support is a cornerstone of Koios’s value addition, fostering a community that encourages innovation, collaboration, and growth.

How accessible will be the solution to users?

The Koios solution is designed for high accessibility, catering to both seasoned developers and newcomers in the Cardano ecosystem.
