Bring the idea. We'll bring the trust layer.

Business case

UNICEF already runs U-Report, an open-source Web2 platform built on RapidPro, to engage young people globally through surveys and polls. The opportunity is to extend that model with a module for verified impact proofs and real-world event reports, anchored on-chain in a privacy-preserving way.

Background

UNICEF delivers programmes for vulnerable children and families and wants credible proof of impact directly from the field. Evidence may cover toilets built, solar panels installed in schools, teacher training, vaccination drives, and nutrition interventions.

Assume a portal exists where micro-tasks for proof collection are published.

Challenge

Enable citizens in the communities where impact occurs to submit proof that programme activities have taken place and are creating impact. Proof may include photos, videos, GPS location, timestamps, survey attestations or other field evidence.

Technical aspects

1. No PII risk: verify attributes such as age and nationality using zero-knowledge proofs or other privacy-preserving technology without exposing personal data.
2. Proof integrity: timestamp and, where appropriate, GPS-stamp evidence in a tamper-resistant way; consider tamper-proof apps, hardware encryption, decentralised storage and on-chain hashes.
3. Multiple attestations: allow several people to attest each proof on-chain, using Ethereum Attestation Service or similar.
4. Offline-first: capture without internet and submit automatically when coverage returns.
5. Accessible UX: assume basic smartphone literacy and abstract Web3 through embedded wallets, gasless transactions and LLM interfaces.
6. Open-source bias: minimise proprietary software and identify open-source alternatives for scale.

Direction to explore

• Extend U-Report with verified impact proofs and real-world event reports.
• Engage youth and community members already active on the platform.
• Plan for eventual U-Report or RapidPro integration.

Business case

Protect trusted humanitarian coordination and reduce the security and privacy risk of relying on consumer messaging platforms for a volunteer network of more than 18,000 people.

Background

The Swedish Red Cross has over 18,000 volunteers in Sweden who currently rely on WhatsApp and traditional messaging platforms. The wider goal is to protect trusted records and help people verify authentic humanitarian communications in an age of misinformation and AI-generated content.

Challenge

How can we build a secure peer-to-peer messaging platform on-chain that enables trusted communication for volunteers?

Technical aspects

• End-to-end encrypted messaging.
• Blockchain identity and authentication.
• Decentralised communication infrastructure.
• Secure volunteer coordination.
• Privacy-preserving messaging.

Business case

Create continuity of humanitarian support across locations, countries and organisations without requiring people to repeatedly prove who they are or what support they qualify for.

Background

People moving across borders because of war, natural disasters or climate emergencies can lose access to essential services. There is no shared system for continuity between humanitarian organisations, or even across the international Red Cross network.

Challenge

Explore whether blockchain can securely preserve access to healthcare, medication, financial assistance and humanitarian support as a person moves from one location or country to another.

Technical aspects

• Portable, privacy-preserving digital identity for displaced people.
• Verifiable credentials for service eligibility across organisations.
• On-chain attestations of received support without exposing PII.
• Interoperability between humanitarian organisations and borders.
• Offline-first access with synchronisation when connectivity returns.

Business case

Protect the Swedish Red Cross as a trusted source during crises by preserving records as an accessible source of truth and making official communications independently verifiable.

Background

Humanitarian volunteers and crisis-response teams need secure, scalable communication infrastructure. Two needs are connected: preserving historical archives and creating verifiable communications so people can determine whether information claiming to come from the Swedish Red Cross is authentic.

Challenge

How can the Swedish Red Cross protect trusted information in an era of misinformation and AI-generated content?

Technical aspects

• Immutable archiving of historical records as an accessible source of truth.
• Verifiable, cryptographically signed official communications.
• On-chain provenance for published humanitarian information.
• Authenticity checks anyone can run against tamper-proof records.
• Secure, scalable crisis communication infrastructure for volunteers.

Business case

Engage younger generations in charitable giving through a donation experience that makes participation rewarding and the use of funds visible.

Background

Hundstallet wants to move beyond a conventional donation flow toward a more transparent and interactive relationship with donors.

Challenge

How can we create a more engaging and transparent donation platform?

Technical aspects

• Blockchain-powered donation tracking.
• Transparent use of funds.
• Gamified donor engagement.
• Digital rewards and community participation.
• Impact dashboards.

Business case

Give influencers and content creators a trusted way to protect their identity, establish ownership and prove the authenticity of their work.

Background

AI-generated content is rapidly increasing, making it more difficult for influencers and content creators to protect their identity and distinguish authentic content from deepfakes.

Challenge

How can blockchain help secure creator identity and prevent deepfakes?

Technical aspects

• Blockchain identity verification.
• Content authenticity certificates.
• Deepfake detection.
• Digital ownership verification.
• Creator provenance.

Business case

Protect patents, research, literature, creative work, inventions and historical records as permanent, verifiable source material for people and AI systems.

The Alexandria Protocols provide the proposed framework: immutable, verifiable records secured by blockchain and advanced cryptography.

Background

As AI grows more powerful, mutable databases create a risk that digital history, original truths, patent blueprints and intellectual property can be altered. The case calls this body of source knowledge humanity's “Digital DNA.”

Challenge

Design a Sovereign History Vault that protects digital truth and prevents AI from rewriting digital history, using the Three Alexandria Protocols as the architectural foundation.

Technical aspects

1. DNA hashing: generate a cryptographic fingerprint that preserves the integrity and authenticity of digital assets.
2. Immutable ledger: register and verify records on an immutable blockchain so they remain tamper-proof and traceable.
3. Post-quantum cryptography: protect assets against future quantum-computing threats with next-generation cryptography.

Direction to explore

• Build a Sovereign History Vault or Sovereign Patent Proof Vault.
• Capture and preserve digital assets, patents, knowledge and important events.
• Verify AI-generated summaries and references against permanent records.
• Hash Digital DNA, register assets on an immutable ledger and secure them with PQC.
• Preserve the integrity of human knowledge for future generations.

Business case

Reduce repeated beneficiary registration and improve humanitarian efficiency while preserving agency sovereignty, avoiding a centralised registry and keeping raw personal data private.

Background

Humanitarian agencies operate in data silos, each with its own registration policies and systems. Comparing records is difficult where reliable biographic data is unavailable and biometric recognition is needed. The infrastructure must be neutral and decentralised, not owned by any one agency.

Challenge

Build a functional prototype of Federated Deduplication Middleware that identifies potential duplicate registrations through cryptographic photo-summarisation.

Technical aspects

1. Summarisation runway: use privacy-preserving primitives, such as Rarimo, to produce photo summaries that are unique enough to compare but strictly non-reversible.
2. Federated middleware: mimic a distributed trust model. The matching engine may identify potential duplicates but must never host PII or master beneficiary records.
3. Result: output a structured deduplication report; do not automatically delete or modify records.

Thursday judging deliverable

Demonstrate a closed-loop prototype with two or more simulated agency endpoints. Generate and exchange summaries, run a deduplication sweep and produce a result on neutral decentralised infrastructure. Simulate at least 1,000 user photos with approximately 10% duplication.

Bonus: add probabilistic confidence thresholds and show how lower-confidence matches can be improved through multi-layered summarisation or secondary biographic validation.
