Identity & Verification

[Campaign Category] Category Questions

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

Prisma DID's introduces three innovations to Cardano:

• Dynamic Contribution Identity capturing real-world actions, not static profiles;
• NFC Peer Verification creating physical-digital trust bridges;
• ALJ Integration transforming impact into verifiable case studies.

We uniquely solve contribution tracking for regenerative networks, turning actions into immutable reputation that drives fair resource distribution.

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

Our prototype implements core technical components:

• WalletConnect-based DID creation using CIP-20 metadata;
• W3C-compliant Verifiable Credential issuance with cryptographic proofs;
• React-based privacy dashboard with selective disclosure controls.
• Testnet-deployed with web interface, validated through ALJ pilot testing.

Final version adds NFC validation and ZK proofs for enhanced privacy and real-world verification.

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

On-Chain Metrics:

• DIDs Created: 250+ within 6 months
• Verifiable Credentials Issued: 500+ within 6 months
• Validation Transactions: 500+ within 6 months

Usage Projections:

• 3+ pilot organizations implementing the system
• 70%+ monthly active user retention
• 50+ instances of cross-network identity portability
• 80%+ of users defining their own data preferences

Projections based on Prisma's existing community engagement, from prior ALJs.

[Your Project and Solution] Solution

Please describe your proposed solution and how it addresses the problem

Proposed Solution

Prisma DID's addresses contribution tracking challenges through a Cardano-native architecture:

Technical Implementation:

• DID Registry: CIP-20 metadata transactions storing IPFS-referenced DID documents
• Verifiable Credentials: W3C-compliant VCs with on-chain hashes and off-chain storage
• Privacy Layer: Selective disclosure with zero-knowledge proofs

Real-World Examples:

• Event Verification:
  • Scenario: Cardano hackathon with 200 participants
  • Process: Participants create DIDs upon registration. Organizers issue VCs for each challenge completed.
  • Validators (other participants) verify contributions through the system. At the end, participants export verifiable proof of their achievements to share with employers or collaborators.
  • Security: Each VC is cryptographically signed by organizers and validators, preventing fraud.
• Developer Safety:
  • Scenario: Open-source contributors verifying their work
  • Process: Developers receive VCs for code contributions to Cardano projects.
  • These credentials serve as a verifiable resume, protecting against impersonation. When applying for grants, developers generate ZK proofs to verify contributions without exposing private keys or personal information.
  • Safety: Developers maintain control over their data, deciding exactly what information to share in each context.
• Impact Network Resource Allocation:
  • Scenario: Climate action network distributing funds
  • Process: Network members earn VCs for verified contributions (tree planting, community education).
  • The governance system uses these credentials to allocate resources fairly, ensuring those who contribute most receive appropriate support.
  • Transparency: All allocations are verifiable on-chain, preventing corruption and building trust.
• Sensitive Research Protection:
  • Scenario: Field researchers collecting environmental data
  • Process: Researchers use DIDs to sign each data submission, creating an immutable record. When sharing with policymakers, they use selective disclosure to verify data integrity without revealing exact locations or sensitive details.
  • Privacy: Zero-knowledge proofs enable verification without exposing underlying sensitive data.

Integration:

• ChatALJ queries contribution data to generate case studies
• Action Learning Journeys track real-world impact
• Partner organizations access selective data through consent APIs

This solution benefits individuals (portable proof of impact), organizations (transparent resource allocation), and Cardano (demonstrating real-world utility).

User Journeys

User Journey 1: Climate Action Network Resource Allocation

1. A Climate org (partner) creates project DID and defines both what they value and how they want to measure them (e.g. we value trees being planted, we measure with this QR+geotagged system).
2. Community member plants trees, takes geotagged photos, scans tree QR code.
3. Three validators (local leader, ecologist, project admin) verify contribution via NFC/digital.
4. System issues Verifiable Credential with contribution details and validator signatures.
5. Governance system queries VCs monthly for transparent fund allocation.
6. Funds distributed automatically to project DID based on verified impact.
7. Contributors receive shareable impact certificates; projects show real-time dashboards.
8. Creates trust in climate funding, prevents greenwashing, enables micro-funding to actual contributors.

User Journey 2: Field Research Data Collection and Verification

1. A Research institution can create a org DID; field researchers create individual DIDs.
2. Researcher collects biodiversity data via eDNA sampler at site, scans test-tube QR code.
3. Mobile app prompts DID signature; data hash written to Cardano, raw data to IPFS.
4. Three validators (technical peer, domain expert, community member) verify data quality.
5. System issues multi-layered VC with biodiversity data and validation proofs.
6. Researcher controls data sharing via privacy dashboard (public/partner/regulator views).
7. ChatALJ queries VCs to generate biodiversity reports and policy recommendations.
8. Solves reproducibility crisis, protects sensitive data, creates portable research credentials.

User Journey 3: Basic DID Creation and Contribution Management

1. The user connects Cardano wallet (Nami/Eternl) to Prisma DID's platform.
2. System generates unique DID anchored to wallet address via CIP-20 metadata.
3. User sets privacy preferences (public/private data, selective disclosure rules).
4. Every organization can issue Verifiable Credential for user's contribution (event attendance, project work).
5. User receives real-time notification of new VC in their privacy dashboard.
6. User controls data sharing, generates ZK proofs for selective disclosure.
7. Community submits feature proposals; users vote using governance tokens weighted by contributions.
8. System evolves based on community decisions, creating self-sustaining identity ecosystem.

[Final Pitch] Value for Money

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

Strategic Alignment & Cost Efficiency

• Prisma DID's represents exceptional value for Cardano by directly advancing the ecosystem's position in decentralized identity while demonstrating real-world utility in impact networks. The budget allocation prioritizes core functionality (50.7% to Development) ensuring maximum impact per ADA spent. By focusing on essential features first - DID creation, credential issuance, and privacy controls - we optimize resource use while planning advanced features (NFC, ZKPs) for post-grant development, maintaining proportional costs to regional developer rates.

Open-Source Multiplier Effect

• All code and documentation will be open-source under our public GitHub repos, creating lasting value beyond the funding period. The ₳38,000 development investment yields reusable DID infrastructure for the entire Cardano ecosystem, while the ₳7,000 in community documentation enables broader adoption. Each DID created represents a potential long-term Cardano user, generating network effects that extend the project's impact far beyond the initial investment.

Risk-Adjusted Investment

• The increased allocation to Testing & Security (₳8,000) and Pilot Implementation (₳7,000) demonstrates prudent resource management. By investing in thorough security audits and real-world validation, we mitigate costly post-launch vulnerabilities and ensure the prototype meets actual user needs. This approach prevents expensive rework and builds trust with both users and stakeholders, maximizing the return on every ADA allocated.

Community Leverage

• The budget leverages Prisma's existing community and ALJ participants (₳7,000 for pilot implementation) to extend impact beyond direct costs. This multiplier effect means every ADA generates additional value through in-kind contributions, testing, and feedback from engaged community members. The ₳7,000 in community documentation and onboarding materials further amplifies this by empowering users to become ambassadors and contributors.

Comparative Value

• The focused scope, combined with our team's expertise in both Web3 development and impact networks, eliminates unnecessary overhead while ensuring technical excellence. The result is a cost-effective solution that addresses a critical need in the Cardano ecosystem while establishing a foundation for future innovation in decentralized identity and verifiable contributions.

Costs are proportional to regional developer rates and reflect streamlined implementation focused on core features first, with advanced functionality (NFC, ZKPs) added in the final version beyond the grant period.
