Despite the promise of blockchain and Web3 in disaster response, key challenges, including scalability, regulation, interoperability, privacy, and energy use, must be addressed to ensure secure, equitable, and practical implementation.
Scalability Limits: Blockchain networks frequently struggle to handle high transaction volumes during disasters, resulting in delays and increased costs. Limited digital access and skills in affected areas further hinder effective deployment.
Legal Uncertainty: The use of cross-border blockchain involves complex regulatory challenges, including data sovereignty, identity verification, and financial compliance. Lack of clear legal frameworks can delay adoption and discourage collaboration in disaster zones.
System Incompatibility: Using fragmented technologies and legacy systems by responders creates integration issues. Without standardized protocols, interoperability suffers, weakening real-time coordination and preserving information silos that impair efficient crisis response.
Privacy Risks: Managing sensitive identity and aid-related data on blockchain demands strong privacy safeguards. Balancing transparency with remains critical to avoid compromising personal information in high-stakes environments.
Energy Demand: High-energy blockchain networks pose sustainability challenges. In disaster zones where power is limited, energy-efficient consensus mechanisms and lightweight infrastructure are crucial for reliable and environmentally conscious deployment.
