GBV Vault

Your Evidence. Your Power. Your Justice.

Inspiration

Gender-based violence remains one of the most under-reported and under-prosecuted crimes in Kenya and across East Africa. Many survivors described the same painful experience:

“When I finally had the courage to report, the police questioned the authenticity of my screenshots…”

For countless survivors, the challenge is not only surviving abuse — it’s proving it.

Evidence gets deleted. Devices are destroyed. Screenshots are dismissed as fabricated. Yet justice requires proof.

This project was inspired by the stories of survivors whose cases collapsed not because the abuse did not occur, but because they lacked legally trusted verification. We heard testimonies like:

A survivor in Nairobi County whose evidence was doubted until blockchain timestamps validated her screenshots.

Mary W. in Mombasa, whose ex-husband claimed the threatening messages were fake — until Hedera verification proved the truth, and the judge accepted the evidence without hesitation.

Their courage demanded a solution. Their struggle demanded innovation.

What it does

GBV Digital Evidence Vault is a secure, private, and blockchain-verified digital evidence preservation platform designed specifically for survivors of gender-based violence.

Survivors can safely preserve evidence without uploading files anywhere. Only cryptographic proofs — never the files themselves — are stored on the Hedera public ledger.

Your Evidence. Your Power. Your Justice.

The system ensures:

Evidence never leaves the survivor’s device

Only tamper-proof hashes are recorded

Timestamps are permanent and court-verifiable

Survivors remain anonymous and in full control

The process aligns with Kenyan digital evidence standards

The platform is built in collaboration with legal aid organizations, women’s shelters, and law enforcement partners across East Africa.

How we built it

We combined blockchain technology, digital forensics, and survivor-centered design to create a solution that is secure, lightweight, and legally credible.

Key development steps included:

Integrating Hedera Hashgraph for immutable timestamp verification

Building a fully client-side hashing engine so files never upload

Designing a simple interface usable under stress or danger

Implementing local encryption for offline safety

Ensuring workflows comply with the Kenyan Evidence Act

Conducting consultations with survivors, legal experts, and GBV support organizations

Everything was built around one core principle: Protect the survivor more than the data.

Challenges we ran into

Developing a platform for such sensitive use cases came with significant challenges:

Preventing exposure of identity or metadata

Making evidence admissible under Kenyan digital evidence regulations

Ensuring the app runs smoothly on low-end devices

Eliminating all cloud storage while maintaining verification

Designing safety features for situations where a device is seized

Helping legal partners understand blockchain-based proof

Balancing innovation with real-world survivor safety risks

Each challenge strengthened the final solution.

Accomplishments that we're proud of

Building the GBV Digital Evidence Vault has been a journey of innovation, empathy, and collaboration. Some of the accomplishments we are most proud of include:

✅ 1. Creating a Survivor-Centered, Privacy-First Platform

We successfully built a system where evidence never leaves the survivor’s device. Only cryptographic proofs are recorded — ensuring complete privacy and safety.

✅ 2. Achieving Blockchain-Verified, Court-Ready Timestamps

By integrating Hedera Hashgraph, we created an immutable timestamping mechanism that aligns with Kenya’s digital evidence standards, making it legally defensible in court.

✅ 3. Designing Trauma-Informed User Experiences

Every feature — from the interface to workflow — was crafted with the emotional state of survivors in mind. Simple, fast, and safe.

✅ 4. Establishing Partnerships Across East Africa

We collaborated with legal aid centers, shelters, and GBV organizations to ensure real-world usefulness and legal relevance.

✅ 5. Helping Survivors Be Believed

Our proudest accomplishment is hearing real stories of survivors whose evidence was validated because of blockchain timestamps — stories where justice became possible.

✅ 6. Building a Fully Offline-Capable System

The tool works even without internet access, ensuring safety in remote or high-risk environments.

✅ 7. Advocating for Tech-Driven Justice

We contributed to awareness around using emerging technology to support human rights, not just financial innovation.

What we learned

Through this project, we learned that:

Survivors need privacy, safety, and simplicity above all

Legal systems demand strict, auditable chains of authenticity

Blockchain can have real impact beyond finance — especially in justice

Trauma-informed design is essential to avoid re-triggering survivors

Community partnerships improve both safety and usability

We also learned the importance of transparency so users can trust the technology protecting them.

What's next for GBV Vault

As we continue building the platform, our roadmap focuses on scale, security, and survivor empowerment.

🔜 1. Mobile App (Android & iOS)

A fully offline-capable native mobile app to make evidence preservation faster and more accessible.

🔜 2. Automated Legal Reports for Court Use

Generate tamper-proof, judge-ready evidence verification documents with a single tap.

🔜 3. Secure Emergency Escape Mode

A safety feature that instantly hides or disguises the app if a survivor is in danger.

🔜 4. Integration with Legal Aid Networks

Allow survivors to securely share verification proofs with authorized advocates only when they choose.

🔜 5. Multi-Language Support

Support for Swahili, Sheng, and other East African languages to increase accessibility.

🔜 6. AI-Assisted Evidence Organization

Help survivors categorize, label, and understand the evidence they collect — without uploading anything online.

🔜 7. Expanding Across Africa

Extend the platform to Uganda, Tanzania, Rwanda, and beyond through regional partnerships.

🔜 8. Formal Certification for Admissibility

Work with judiciary and law enforcement bodies to create standardized digital evidence protocols powered by blockchain technology.
