[Campaign Category] Category Questions

Describe what makes your idea innovative compared to what has been previously funded (whether by you or others).

This innovation puts human privacy first. While other solutions force users to trade their data for access, this project empowers them to prove who they are without revealing what they are. This is a breakthrough for high-trust interactions. It means a family can verify a caregiver's credentials with absolute certainty while protecting everyone's privacy. This unlocks a future where trust and privacy are not mutually exclusive, enabling safer and more humane digital connections on Cardano.

Describe what your prototype or MVP will demonstrate, and where it can be accessed.

The MVP will demonstrate this new standard of privacy. A user will log into the app and be prompted to link their Atala PRISM wallet. With a single click, they can grant permission to verify a credential (e.g., "Verified Community Member") without exposing any other data. The experience will feel seamless and secure. This will be demonstrated in a compelling video and be accessible on our staging app. The user will feel a sense of control and security, proving that robust identity verification and privacy can coexist beautifully.

Describe realistic measures of success, ideally with on-chain metrics.

Success is measured by the peace of mind this tool provides. The primary community metric will be the number of users who successfully and voluntarily link their digital identity to the platform. The initial goal is to onboard 200+ users to this new privacy-preserving standard in the first 3 months. This will be supplemented by measuring user satisfaction, aiming for 90% of participants to report feeling more secure using our platform compared to traditional login methods.

[Your Project and Solution] Solution

Please describe your proposed solution and how it addresses the problem

The need for trust is universal, but it becomes critically urgent in high-stakes human interactions. Consider the global health caregiving market, a sector valued at over $233 billion in 2025, where a family’s peace of mind depends entirely on the trustworthiness of the person they hire. Today, this trust is fragile, built on slow, fragmented background checks that force users to surrender their most sensitive personal data to centralized platforms, creating a significant privacy risk. This is the digital trust gap that Cardano is uniquely positioned to close, and the time is now.

This proposal will equip the Cardano ecosystem with the definitive blueprint for high-trust, privacy-preserving identity by integrating Cardano’s native, enterprise-grade identity layer, Atala PRISM, into a real-world application. Think of Atala PRISM as a user’s “digital passport.” It allows them to hold verified credentials (like a nursing license or a background check) securely in their own digital wallet. For the first time, a dApp on Cardano will be able to ask for proof of that credential without needing to see or store the underlying personal data.

Crucially, this vision is not starting from zero. This advanced identity layer will be integrated into the existing Aladin Work application, which is **already live **and available on both the Apple App Store and Google Play. The community is not funding an idea, but the acceleration of a moving train. The challenges of app development, deployment, and initial user acquisition have already been solved. This proposal is laser-focused on a single, strategic objective: building the open-source guide for implementing Atala PRISM in a live, consumer-facing environment.

This MVP will deliver a fully functional end-to-end integration: from a user linking their DID, to Aladin issuing a Verifiable Credential, to the user presenting that credential for instant, privacy-preserving verification. While this initial integration is within Aladin, the ultimate deliverable is a public good. This is a single, calculated step in a much larger journey to make Cardano the global standard for trusted digital interactions.

Introduction a bout the Aladin platform

Redefining the Gig Economy

• Aladin is a decentralized protocol and application built on Cardano, with a mission to provide a fair, transparent, and efficient infrastructure for the global job economy.
• Our philosophy is encapsulated in the name Aladin, inspired by the timeless story of empowerment. In our ecosystem, every user is an 'Aladin' - empowered as the protagonist of their own journey, holding complete control. The $LAMP token is not merely an asset; it is their 'Magic Lamp' - the key to unlocking the full power of the protocol.
• By holding $LAMP and making a request - whether it's seeking talented personnel for a complex project or finding help to fix a gas stove at home - an Aladin summons their 'Genie', ready to turn their wishes into tangible outcomes, safely and transparently.

Utilities

Aladin platform operates on three core utilities:

1. Simplified Hiring: Aladin helps employers easily find suitable candidates based on their on-chain reputation (represented by their CVC score), minimizing time spent on interviews and manual verification.
2. High-Commitment Contracts: Smart contracts automatically lock the committed assets ($LAMP) of both parties, creating a serious work environment and ensuring both sides fulfill their responsibilities.
3. Verifiable Proof of Experience: Aladin encodes the experience accumulated through each successfully completed contract into a CVC score. This reputation is immutable, owned by the user, and can be leveraged across the entire Web3 ecosystem, not just on the Aladin app.

Problems

Hurdles of the Modern Gig Economy

• Lack of Trust and Commitment: Parties are often hesitant to engage due to the absence of mechanisms that guarantee contract enforcement and fair payment.
• Difficult to Verify Experience: Resumes and recommendation letters are easily forged and do not reflect true capabilities, leading to risks for employers.
• Walled Gardens (Data Silos): A worker's valuable experience on one platform (e.g., Upwork) cannot be transferred to another, forcing them to build their reputation from scratch repeatedly.
• High Fees and Opaque Processes: Incumbent platforms charge high service fees, and their dispute resolution processes are often centralized, non-transparent, and potentially biased.

Solutions

Aladin, A Global Trust and Reputation Layer

• Aladin is more than just an application; it is a foundational protocol that solves the above issues by:
• Establishing Trust through asset-backed escrow smart contracts.
• Building Immutable Reputation via the on-chain CVC score, which reflects both experience and commitment.
• Ensuring Justice with a decentralized arbitration system where the community, acting as Sultans, resolves disputes.
• Promoting Open Interoperability through the Job-SCaaS model, allowing any other application to leverage Aladin's infrastructure.

What is CVC?

CVC (Committed Value in the Contract) is Aladin's core reputation score.

• Calculation: The CVC value of a contract is based on the value of the staked $LAMP, pegged to a reliable stablecoin to insulate the reputation score from token price volatility.

Accumulation: Upon successful completion of a job, the final transaction consumes the old reputation UTXO and creates a new one with an updated CVC score for both the Aladin and the Genie, permanently recording the experience on-chain.

Aladin Ecosystem

• The Aladin ecosystem consists of two key components working in symbiosis:
• The Aladin Protocol: The decentralized infrastructure layer, comprising smart contracts, Aladin Nodes, and governance rules.
• The Aladin App: The user-facing application (web/mobile) that allows end-users to easily interact with the Aladin Protocol.

Key Roles in the Aladin App

• Aladin: An individual or organization with a need, who posts a job or project.
• Genie: A skilled individual who performs the requested job.
• Sultan: The arbiters who are high-reputation Aladins or Genies (with high CVC scores). They can be nominated to the Petition Resolution Council to adjudicate disputes in specific job contracts.

How Aladin Works:

The Lifecycle of a Job Smart Contract

The workflow of a contract on Aladin is designed to cover real-world scenarios, from initiation to either successful completion or failure.

1. Start: An Aladin posts a job request and criteria. The protocol suggests suitable Genies.
2. Contract Setup: The Aladin and Genie agree on terms and sign the smart contract.
3. Escrow: Both parties escrow $LAMP tokens. A Hydra Head can be opened for complex tasks.
4. Execution: The Genie performs the tasks.
5. Resolution: If it is Completed, both parties agree, the contract succeeds, funds are distributed, and the Treasury is updated. If it is Petition: In case of a dispute, the arbitration process with a Sultan is initiated. If the Deadline Risk: The Aladin may choose to outsource through a trusted Aladin Service Provider.
6. Reputation Update: Regardless of the outcome, the CVC scores of both parties are adjusted accordingly.
7. End: The smart contract is closed, the Hydra is closed also (if yes)

Petition Process

1. Dispute Resolution by the Sultanate
2. This is the core mechanism for ensuring fairness.
3. Initiation: An Aladin or Genie initiates the "Dispute" path.
4. Participation: A Sultan Council is randomly convened from high-reputation (high CVC) Genies and Aladins with relevant experience. They are tasked with arbitrating the dispute and casting votes to reach a final verdict.
5. Outcome: If the Genie Wins, the Genie receives the payment and the full escrowed amount from both parties. And if the Aladin Wins: The Aladin receives a full refund of the escrowed amount from both parties.
6. Consequence: The losing party's CVC score is negatively impacted. Transaction fees from the fund distribution are sent to the Treasury.

[Your Project and Solution] Impact

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

The impact of this project extends far beyond a single application; it creates a vital piece of public infrastructure for the entire Cardano ecosystem.

The immediate, measurable goal is to onboard over 200 real users to link their digital identity within the first three months. This isn't just a vanity metric; it is a critical validation of the Atala PRISM user experience in a live environment. It proves that decentralized identity is not just for crypto-natives, but is ready for mainstream adoption. The successful onboarding of these f**irst 200 users **will create an invaluable feedback loop, allowing for the refinement of the process and the publication of a best-practice guide for the entire community.

From this solid foundation, the impact ripples outwards, creating an ecosystem-wide flywheel of innovation. The open-source "Integration Guide" will become the go-to resource for any Cardano project that requires identity verification:

• DeFi Protocols: A project focused on real-world asset tokenization could use this guide to implement compliant, privacy-preserving KYC. Before, they faced a massive technical and regulatory hurdle. After, they have a clear, community-vetted path to verifying users without centralizing sensitive data.
• DAO Governance: A DAO could use this guide to implement a one-person-one-vote system based on a verified, unique human identity. This solves the critical Sybil-resistance problem, enabling fairer and more secure decentralized governance.

Ultimately, this project transforms a complex technology into a simple, powerful tool that reinforces Cardano's vision of building systems that empower individuals. It doesn't just deliver a feature; it delivers the key that unlocks the next generation of high-trust, real-world

[Your Project and Solution] Capabilities & 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?

This proposal doesn't ask the community to fund a project from an idea on a napkin; it asks the community to fund the acceleration of a moving train. The Aladin Work application is already live on the iOS and Android stores, a tangible and public demonstration of the team's ability to deliver polished, user-facing products. This existing momentum dramatically de-risks the community's investment.

To bring this powerful tool to life, a team with specific, battle-tested experience is required. This project is feasible because it is helmed by the right experts for each critical challenge:

1. The challenge of building a trusted, scalable network is immense. That's why this project is led by **Duc Le **(CEO), who has already scaled a retail network to over 1,000 medicin shops in 3 years.
2. The challenge of integrating enterprise-grade technology is non-negotiable. That's why the technical strategy is led by Nguyen Mau Luu (CTO), the former chief architect of the Optimal9 Core Banking System, a mission-critical platform demanding the highest levels of security.
3. The challenge of creating a dApp people actually love to use is what separates good ideas from adopted products. That's why the user experience is guided by An Nguyen (Off-chain Lead), who previously led an app to over 500,000 downloads.
4. The challenge of delivering on promises to the Catalyst community requires experience. That's why the on-chain development is led by Nguyen Vu Hoang (On-chain Lead), a Catalyst veteran with a proven track record of successfully delivering on previous Catalyst-funded projects (ProSkill).

This team's commitment to transparency is a covenant with the community. The detailed, verifiable milestones and commitment to regular updates ensure every voter has a clear, real-time view of how their delegated funds are empowering the ecosystem, every step of the way. This rigorous process is our promise of accountability.

End-to-End VC Verification

Milestone Outputs

A fully implemented, user-facing feature in the Aladin Testnet dApp where the application is capable of requesting proof of a specific credential from the user. This process generates a formal presentation request to the user’s PRISM wallet, demonstrating how selective disclosure can be applied in high-trust gig scenarios.

Acceptance Criteria

A user successfully receives a credential presentation request in their PRISM wallet, reviews the details, and selects the correct Verifiable Credential (VC) to share. The Aladin application must then cryptographically verify the credential against the issuer’s DID, validate its integrity and authenticity, and update the user interface with a clear confirmation that the credential has been verified. The flow should be smooth, secure, and repeatable across multiple test users.

Evidence of Completion

A link to the live Testnet staging environment where reviewers can directly test the end-to-end verification process. Additionally, a comprehensive demonstration video will be published showing the entire flow in detail: the dApp initiates the request, the user selects and presents their VC through their PRISM wallet, and the Aladin app confirms verification by displaying a “Verified” status on-screen.

[Final Pitch] Value for Money

How does the cost of the project represent value for the Cardano ecosystem?

• This proposal represents an asymmetric bet for the Cardano Treasury: a modest investment to unlock a foundational trust layer for the $233 billion global caregiving market and the burgeoning $69 billion decentralized identity market. The requested budget is only a fraction of what it would cost a single enterprise to research, develop, and deploy a comparable identity solution from scratch.
• By funding this project, the Cardano Treasury is effectively “buying in bulk”—funding this complex R&D once, for the benefit of the entire ecosystem. Our final, open-source Integration Guide will save countless future projects tens of thousands of dollars and months of development time, multiplying the value of the Treasury’s initial investment.
• The on-chain flywheel effect will provide a tangible return. By enabling high-trust applications, this project will attract a new class of users and businesses to Cardano that were previously unable to operate in a trust-minimized environment. This activity boosts key network metrics and creates a powerful showcase of Cardano’s unique, enterprise-ready capabilities.
• This is not a speculative gamble. It is a calculated, intelligent investment in a team with proven momentum and existing assets, targeting a vast, validated market. Funding this proposal means acquiring a high-value, strategic asset that will accelerate Cardano’s mission for years to come.

As the table illustrates, the value generation for the Cardano network is designed to grow exponentially:

• It begins with the Foundation Phase, where achieving a modest 500 contracts per day will already generate over ₳36,500 in annual network fees—a solid return on the initial Catalyst investment.
• As the product-market fit is validated in the Optimize Phase, this activity is projected to increase significantly, generating over ₳219,000 in annual fees.
• This is where the flywheel truly ignites. During the Scale-Up Phase, as Aladin captures a larger market share, the platform is projected to handle 30,000 contracts daily, generating over 2.1 million ADA in network transaction fees every year.
• In its mature Governance Phase, the platform has the potential to generate over **7.3 million ADA in annual **fees, turning real-world economic activity into a massive, sustainable source of value for the entire Cardano network.

This phased growth unequivocally demonstrates that the value returned to the Cardano Treasury is projected to be many multiples of the total funding required for Aladin's foundational proposals. But the impact transcends financials. This level of consistent, real-world economic activity serves as a powerful beacon, significantly enhancing social proof and trust in the Cardano ecosystem for the entire world to see. It is a direct and tangible contribution to transforming the Cardano's vision of "1 billion users" from an aspiration into an achievable reality.
