What is it about?
This paper proposes a new system for sharing sensitive disaster-related data using blockchain and zero-knowledge proofs (ZKPs). During disasters, fast and secure data exchange between stakeholders like governments, NGOs, and rescue teams is critical. The authors introduce a prototype platform called DS4H that enables secure and decentralized data sharing without exposing private information. It uses decentralized identifiers (DIDs) and ZKPs to verify users and data integrity while maintaining privacy.

Why is it important?
- Disasters require urgent decisions, and data delays or breaches can cost lives. - Current systems are centralized and slow, making them vulnerable to attacks, censorship, or breakdowns. - This work offers a privacy-preserving, trustless, and real-time alternative that empowers all parties to verify and access only what they need without compromising sensitive information.
Perspectives
✅ Interdisciplinary Impact: Combines blockchain, cryptography, and disaster informatics to create a next-gen public infrastructure. ✅ Sustainability: By removing central authorities, the system lowers costs, increases resilience, and aligns with long-term digital governance goals. ✅ Reusability: This model could also be adapted for secure data sharing in healthcare, education, or humanitarian aid.
