Please describe your proposed solution

Existing financial service solutions in emerging markets do not truly understand and address underserved communities' unique challenges and varied needs. The problems include low digital literacy, high transaction costs, lack of compliance, privacy, and financial infrastructure, resulting in a financial inclusion gap.

Our solution introduces a Cardano Blockchain-based system for an affordable alternative to cross-border payment while adhering to regulatory standards. Using Zero-knowledge proofs (ZKPs), our service can comply without compromising sensitive user information.

When a user undergoes KYC, we mint a token on Cardano with the hash of their data. The actual KYC data will be stored with the company (Defy Financial). The token proves that the KYC procedure was performed at a particular date and time. The KYC token helps track the evolution of the user’s KYC data.

We will create zero knowledge circuits based on real-world banking requirements. These circuits encode the requirements and enable the company to prove that the users’ KYC data satisfies those requirements.

Examples:

check that the transaction does not involve sanctioned countries

check that the user is more than 18 years old

check that the transaction has been signed with enough “signing power.”

We will also develop proof generator software (backend) and proof verifier software (backend). Given the transaction details, proof generator software will generate the proof of validity, and proof verifier software will verify the proofs.

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

The Cardano community has always been focused on solving real-world problems and using Blockchain for Good. Our solution attempts to carry on the novel mission of banking the unbanked.

. This proposal leverages Zero-Knowledge Proofs (ZKPs) on Cardano to provide secure and inclusive finance. Prioritizing user privacy, data triangulation, and regulatory compliance fosters trust and transparency, attracting new users and developers to the Cardano ecosystem.

Unlocking Financial Inclusion:

• Unbanked and Underserved Populations: The solution expands financial access for those lacking traditional banking services. Integrating ZKPs ensures user privacy while enabling secure transactions and KYC verification through triangulation.

• Increased Trust and Transparency: Immutable transaction records and automated regulatory compliance through smart contracts build trust within the network, attracting more users and developers.

Boosting the Cardano Ecosystem:

• Onboarding Users: Cardano establishes itself as a robust and reliable platform for secure and compliant financial transactions. This can help us attract new users, developers, institutions, and investors.

• Real-world Impact: The solution fosters financial inclusion and economic development in emerging markets, showcasing Cardano's potential.

This proposal will help Cardano become the leading chain in driving financial inclusion and sustainable economic development through innovative blockchain solutions.

What are the key milestones you need to achieve in order to complete your project successfully?

Milestone 1: Ability to mint KYC token with the hash of the user's KYC data

Milestone 2: Zero-knowledge circuits based on real-world banking requirements. These circuits will be used to generate proofs.

Milestone 3: Developing a proof-generator software (backend). This software will use Zero Knowledge circuits to build ZK proofs to prove user data without disclosing it.

Milestone 4: Developing a Proof verifier software (backend). The verifier will be able to verify the generated proof, allowing institutions or banks to verify information without having access to the data.

Final Milestone: A video, documentation, and a whitepaper illustrating the MVP functionality

Who is in the project team and what are their roles?
