Combating cryptocrime and fraud in Small Island Developing States’ disaster management: A blockchain-based framework

Blockchain technology offers transformative potential for disaster response and management in Small Island Developing States (SIDS), which are particularly vulnerable to disasters or face heightened disaster risks due to geographic isolation and limited resources. By providing a decentralized, immutable, and transparent ledger, blockchain technology facilitates secure data sharing, streamlines disaster logistics, and enhances emergency aid distribution, fostering resilience in disaster-prone regions. However, risks of cryptocrime, such as money laundering and smart contract exploits, can undermine its benefits. This chapter examines blockchain’s applications in disaster logistics, community identification, and resource allocation, highlighting its role in reducing fraud and building trust. We propose the Blockchain Response Efficacy Model (BREM) to assess the efficiency, transparency, and fraud risks associated with SIDS. Through case studies and literature analysis, we offer insights to strengthen disaster resilience while mitigating cryptocrime vulnerabilities.
