Post-disaster aid logistics is frequently affected by fragmented data, mismatches between needs and availability, distribution delays, and weak accountability. This study integrates a systematic literature review (SLR) and a proof-of-concept (PoC) to examine how blockchain can support data governance and aid traceability. Articles published in 2020-2025 were retrieved from ScienceDirect and Scopus, selected using PRISMA principles, and synthesized thematically from 31 eligible studies. The synthesis identified coordination and information alignment, along with traceability of goods, funds, beneficiaries, and delivery status, as the dominant issues. Frequently reported mechanisms included distributed ledgers, smart contracts, audit trails, cryptographic identities, and role verification. These findings were translated into a Solidity-based smart-contract PoC on a local Ganache network covering requests, stock, allocation, shipment, receipt validation, and event logs. Three synthetic scenarios and an access-control test showed that valid transactions were recorded, over-allocation was rejected, receipt discrepancies were flagged, and unauthorized operations were reverted. Blockchain is therefore better positioned as an infrastructure for data governance and transaction validation than as a standalone solution to all disaster-logistics problems.
Blockchain and distributed ledger technology (DLT) have been proposed for humanitarian operations because their shared-ledger characteristics may support transparency, traceability, accountability and coordination across organisations. This systematic evidence review synthesises research on operational benefits, adoption barriers, implementation conditions and evidence gaps in humanitarian supply chains. The evidence includes systematic reviews, empirical pilot research, expert-based barrier analysis, case-based design research and implementation-framework studies. Across the literature, the most consistently reported potential benefits are visibility, traceability, transparency, auditability, trust and inter-organisational information sharing. The empirical base is smaller than the conceptual literature, and barriers include regulatory uncertainty, skills and training, sustainability costs, privacy, infrastructure, scalability, interoperability and governance. The review proposes an eight-stage implementation pathway centred on problem diagnosis, technology justification, governance, privacy-aware architecture, piloting, capacity building, evaluation and controlled scaling. The framework is a synthesis proposed by the author from the reviewed evidence, rather than a tested causal model. The review concludes that blockchain should be selected conditionally, where multiple independent actors need a shared auditable record and where the expected coordination value justifies the additional technological and governance complexity.
