[GENERAL] Please specify how many months you expect your project to last (from 2-12 months)

[GENERAL] Please indicate if your proposal has been auto-translated into English from another language.

No

[GENERAL] Does your project have any dependencies on other organizations, technical or otherwise?

Yes

[GENERAL] If YES, please describe what the dependency is and why you believe it is essential for your project’s delivery. If NO, please write “No dependencies.” in this field.

We use a third-party software like PostgreSQL, Cardano Node, DB-Sync, NodeJS, and some JS/CSS frameworks and libraries like progressive JavaScript reactive framework VueJS or CSS UIkit framework for rapid prototyping and fast development. All the dependencies are open source. There are no external factors (such as third-party suppliers, external resources, third-party software, etc.) that may cause a delay.

[GENERAL] Will your project outputs be fully Open Source?

No

[GENERAL] If NO, please describe which outputs are not going to be open source. If YES, please write “Project will be fully open source.” in this field.

Eventually the project will be fully open source. However, for now, the answer is No, since this will not happen immediately after the project completion.

Explorers

[IMPACT] Please describe your proposed solution.

Explorers are an important part of every blockchain ecosystem. Cardano is no exception. Since none of the Testnets explorers is perfect and each has both advantages and disadvantages (for example, some don't show account rewards, others may display non-real-time data, i.e. display cached data, etc), it is very important to give developers and users the opportunity to choose which explorer they will use for a particular request. Our team has already developed the AdaStat.net Cardano Explorer for the mainnet, and now we want to do the same for the both Pre-prod and Preview testnets. In addition, as far as I know, none of existing Testnet Explorer has a public API. AdaStat will have the public API for both Pre-prod and Preview testnets.

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

Following the principles of decentralization, it is very important for users to have an access to blockchain data in different explorers. Since users should not trust any of the explorers, they should be able to compare data in different explorers. Also, convenience and simplicity of interacting with blockchain data will potentially attract more blockchain developers.

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

The key metrics will be the number of site users and the number of developers using the API. An indicator of success will be represented by the growth of these metrics.

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

We plan to share the outputs and results of this project through AdaStat Twitter account as well as Cardano TG Groups like Cardano Developers, Cardano StakePool Operators, Cardano Stake Pool Best Practice, etc

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

As mentioned above, our team has already developed the AdaStat Cardano Explorer for the mainnet. So we have enough experience and understanding of how and what to do to achieve results.

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

The main goal is developing and running a fully functional Cardano Explorer for both Pre-prod and Preview testnets, as well as developing API for both.

[CAPABILITY/ FEASIBILITY] Please provide a detailed breakdown of your project’s milestones and each of the main tasks or activities to reach the milestone plus the expected timeline for the delivery.

The development process will take approximately 2 months and will have 2 milestones:

Milestone 1

• Tasks: renting and configuring servers, network infrastructure, database, as well as preparing and launching the back-end part of the project.
• Duration: 1 month

Final Acceptance Milestone 2

• Tasks: preparing and launching the front-end part of the project.
• Duration: 1 month

[CAPABILITY/ FEASIBILITY] Please describe the deliverables, outputs and intended outcomes of each milestone.

Milestone 1

• Deliverables: by the end of the first month, we expect that the both API sites api.preprod.adastat.net and api.preview.adastat.net will be fully available.

Final Acceptance Milestone 2

• Deliverables: by the end of the second month, we expect that the both sites preprod.adastat.net and preview.adastat.net will be online and the project will be completed.

[RESOURCES & VALUE FOR MONEY] Please provide a detailed budget breakdown of the proposed work and resources.

The total requested funds are 50,000 ADA, which is equal to ~$14,000 at the current rate

• Servers and infrastructure cost for 2 years: 2 servers each ~$100/month = $200/month * 24 months = $4,800 (~17,000 ADA)
• Developers salary (2 developers): $9,200 (~33,000 ADA)

Initial Payment

• Servers and infrastructure cost: 15,000 ADA
• Total cost: 15,000 ADA

Milestone 1

• Estimated man-hours: 84 hours
• Developers salary: 15,000 ADA
• Total cost: 15,000 ADA

Final Acceptance Milestone 2

• Estimated man-hours: 100 hours
• Developers salary: 18,000 ADA
• Servers and infrastructure cost: 2,000 ADA
• Total cost: 20,000 ADA

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

The average cost of development per hour is 50$. We assume that our 2 devs will not spend more than 25% of their working time (i.e. 2 hours per day / each dev = 4 hours per day). We also assume that the project will take 2 month (i.e. 46 working days). So we can calculate the total amount

• 46 * 4 hours = 184 hours
• 184 hours * $50 = $9,200

which is equal our team work cost.

[IMPORTANT NOTE] The Applicant agreed to Fund10 rules and also that data in the Submission Form and other data provided by the project team during the course of the project will be publicly available.
