Please describe your proposed solution

1. The solution proposes that the marketplace for verification will contain jobs/tasks created and published from the reitcircles platform when new assets are requested for verification.
2. Different players such as notary, legal verifiers, real estate agents and other players in the ecosystem, can register on the platform and request jobs to be allocated to them.
3. The job allocations will be done on the basis of different parameters such as region, city, province , country, qualifications, age and reviews.
4. Smart contract driven workflow will determine the lifecycle of tasks published on the marketplace. Role tokens will manage authorization on the platform. A platform-oracle will update completion-flags on datums.
5. The automation of tasks for verification will allow neutrality of different participants as far as verifying an asset. More than one verifier per task can be an option so that oracle based solutions can be implemented.

<u>Who will your project engage</u>

• We will be working with real world projects involved in real estate (including ESG driven projects such as green energy, mining etc.).

<u>How will you demonstrate or prove your impact</u>

• The data being used in these projects, will be verified and put on chain. We will comply with country laws etc. for this purpose.

<u>Explain what is unique about your solution, who will benefit, and why this is important to Cardano.</u>

Cardano will benefit from dApps built on the platform. Our technology provides a firm foundation for other data analytics apps that can exploit the data that real world actors will be putting on the chain and create industry / segment specific apps.

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

<u>In what way will the success of your project bring value to the Cardano Community?</u>

• Blockchain is now entering the world of real world adoption. Projects such as Reitcircles are leading the way for this, with the goal of creating open data standards and libraries to interact with data generated.

<u>How will you measure this impact?</u>

Number of apps building on the cardano block chain with real world applications.

<u>How will you share the outputs and opportunities that result from your project?</u>

The smart contract will be outsourced so that different projects can use the same.

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?

Reitcircles has achieved the following milestones already:

• A working portal with wallet based login

• An onboarding module with document upload and review

• Payment module for taking NFT payments and minting the same.

• House NFT creation based on documents and smart contract based verification.

• Portal based chat communication between members of the platform.

• Role NFT based access to the platform.

• Smart contract based REIT token issuance replicating BTC (with halving every 4 years)

Our team brings in more than 40+ yrs of software development experience.

• Antonio Hernandez-Garduno: Platform lead in Smart contract development who is a PhD graduate from Caltech, leading security solutions.
• Tony Mönicke: Computer science graduate based in Berlin and working in cardano ecosystem for last 2+ years.
• Nilay Saha: Worked in leading multinational companies such as ASML, AUDI, Hilti and extensive experience in banking. Has 25+ years of development, solutions architecture and technical leadership experience in large/mid size industry.
• An Sy, Vinh tuan: Developers working on the platform (frontend and backend)
• Giang Nguyen: UI/UX lead

We will be delivering using open source code, where commits can be monitored. And to give a proof of concept / working version, we will integrate the same into our verification platform that is already live on mainnet.
