Blockchain for social good: A review of applications in humanitarian aid and social initiatives

Blockchain technology has emerged as a revolutionary force with the potential to address pressing social challenges and transform traditional paradigms in humanitarian aid and social initiatives. This paper provides a comprehensive review of the diverse applications of blockchain in fostering social good, particularly in the realms of humanitarian aid and social initiatives. The decentralized and transparent nature of blockchain offers a paradigm shift in the way charitable organizations operate and deliver aid. Smart contracts on blockchain enable transparent and tamper-resistant transactions, ensuring that resources are allocated efficiently and reach intended beneficiaries. The elimination of intermediaries reduces the risk of corruption and ensures a more direct and accountable flow of funds. In the context of humanitarian aid, blockchain facilitates the creation of decentralized identity systems, ensuring secure and verifiable identities for displaced populations. This aids in the efficient delivery of aid, as well as financial inclusion for those without access to traditional banking services. Moreover, blockchain enhances supply chain transparency, enabling the tracking of donations from inception to distribution, reducing fraud and ensuring the authenticity of goods. Social initiatives, too, benefit from blockchain's transformative capabilities. Decentralized autonomous organizations (DAOs) enable communities to collectively make decisions and manage resources. This fosters a sense of ownership and empowerment among participants, promoting sustainable social development. Additionally, blockchain-based token economies incentivize positive behaviors, encouraging individuals to contribute to social causes in meaningful ways. Despite these promising applications, challenges such as scalability, regulatory uncertainties, and technological literacy remain. This paper calls for continued research and collaboration to unlock the full potential of blockchain for social good, emphasizing the need for innovative solutions that can address the unique challenges faced by humanitarian and social initiatives.
