[SOLUTION] Please describe your proposed solution

• What is CardanoBI?

CardanoBI is the first fully Open-Source Business Intelligence API Layer for Cardano.

It exposes data grouped in 3 distinct Domains:

1. Core: all on-chain data of Cardano (accounts, blocks, transactions, contracts, pools....)
2. Analytics: data derived from Core offering offering analytics data points
3. Partner: on-chain and off-chain data, showcasing the business value outcome of Projects delivering utility on Cardano (think of it as the Bloomberg of Cardano where Financial Institutions, News Agencies, Trades alike can get access to the business data of Cardano products (Oracle, DEX, Defi ....)

• What is our Java SDK?

It is a set of tools, libraries and documentation, allowing Java developers to integrate the CardanoBI API in their own Java application.

The benefits for Java developers is that they can directly augment their application's code base, with a streamlined access to Cardano's data, without having to get outside of their technology stack.

This allows them to build on Cardano in a more efficient and consistent manner, promoting shorter time to market and greater software quality.

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

The benefits of this solution to the Cardano ecosystem are significant.

Firstly, it simplifies the process of developing utilities on Cardano, by offering a better Java Developer Experience.

Secondly, by commoditizing the access to Cardano's data to Java developers, we will attract more Java developers and businesses to leverage Cardano's capabilities.

This increased interest and participation in the ecosystem will contribute to its growth and vitality.

[CAPABILITY & FEASIBILITY] 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?

We are the team that successfully built and launched CardanoBI.

The proposed solution will be built by the same team.

We have 23+ years' experience in software development for the financial industry and will be as transparent in our project reporting as we have been for the initial CardanoBI project.

We have Java development experience.

[VALUE FOR MONEY] How does the cost of the project represent value for money for the Cardano ecosystem?

The cost of the project represents value for money for the Cardano ecosystem in several ways:

1. Enhancing Development and Innovation: The investment in developing the CardanoBI Java SDK and its associated components facilitates the creation of innovative applications and services on Cardano. This leads to increased developer engagement and brings new ideas and solutions to the ecosystem. The resulting innovation and growth contribute to the overall value and competitiveness of the Cardano platform.
2. Supporting Ecosystem Expansion: The costs associated with the project contribute to the expansion of the Cardano ecosystem by enabling the creation of utility services. These services unlock the business value stored in Cardano's on-chain data, promoting the growth of the ecosystem as a whole. This expansion attracts more users, stakeholders, and investment, creating a virtuous cycle that amplifies the overall value proposition of Cardano

Furthermore the provided hourly rates are highly competitive when you consider the level of expertise of these resources.
