Blockchain technology is more than a buzzword: it’s a practical solution transforming lives, particularly in emerging economies. By providing transparency, efficiency, and enhanced traceability, blockchain is helping nations address critical global challenges outlined in the United Nations’ Sustainable Development Goals (SDGs). As 2025 unfolds, the potential of blockchain to revolutionise key sectors in these economies is becoming more evident.
Ending Poverty (SDG 1): A Lifeline for the Unbanked
In emerging economies, a substantial portion of the population remains unbanked, lacking access to essential financial services. Blockchain technology is bridging this gap by enabling secure access to financial tools without relying on traditional banks. Decentralised finance (DeFi) platforms offer services such as microloans, savings accounts, and payment systems, empowering individuals to improve their livelihoods.
For instance, blockchain-based microfinance initiatives in rural Africa have enabled farmers to access affordable loans, purchase better seeds, and increase their crop yields. Additionally, companies like AZA Group (formerly BitPesa) have facilitated cross-border payments in Africa, reducing transaction costs and increasing efficiency for businesses and individuals.
By providing these tools, blockchain technology directly addresses poverty by equipping individuals and communities with the resources they need to enhance their income and achieve financial independence.
Clean Water and Sanitation (SDG 6): Efficient Resource Management
Access to clean water remains a critical issue in many developing nations. Blockchain technology is improving how water resources are tracked and managed. By integrating blockchain into water distribution systems, governments and NGOs can monitor usage and prevent wastage, ensuring resources reach the communities that need them most.
For example, SweetSenseuses sensors combined with blockchain to monitor water pump functionality in rural areas. This system ensures timely maintenance and consistent access to clean water, making a significant impact in regions where water scarcity is a daily challenge.
Affordable and Clean Energy (SDG 7): Empowering Communities
Energy inequality is a persistent problem, particularly in rural areas. Blockchain holds significant potential to address this issue by enabling peer-to-peer energy trading. Households and businesses with surplus solar energy can sell it directly to others, creating decentralised, community-driven energy networks that foster inclusivity and sustainability.
For example, projects like Power Ledger have successfully explored peer-to-peer energy trading using blockchain in locations such as Australia and Thailand, proving the technical feasibility of these systems. While blockchain-based microgrids in Nigeria are still largely in the research and pilot stages, these international projects highlight the potential for similar solutions to transform energy access in emerging economies.
Scaling such initiatives in Nigeria and other regions will require overcoming infrastructure challenges, regulatory hurdles, and integration with existing energy grids. However, the success of blockchain-enabled energy trading elsewhere shows that with the right support, decentralised energy systems can become a reality.
Climate Action (SDG 13): Driving Accountability
Climate change is one of the most pressing challenges of our time, and blockchain is emerging as a tool to enhance accountability in tackling it. Platforms built on blockchain can track and tokenise carbon credits, ensuring emissions reductions are accurately recorded and verified. By enabling transparent trading of carbon offsets, blockchain holds businesses accountable for their emissions and encourages investments in sustainable practices.
For example, the World Bank has explored blockchain’s potential for tracking carbon credits, demonstrating how this technology can improve the efficiency and transparency of carbon markets. However, significant challenges remain in establishing standardised methodologies for measuring and verifying emissions reductions. Addressing these issues is critical to ensuring the integrity and scalability of blockchain-based climate solutions.
Partnerships for the Goals (SDG 17): Building Global Trust
Achieving the Sustainable Development Goals (SDGs) requires seamless collaboration among governments, businesses, and nonprofits. Blockchain fosters these partnerships by providing a transparent platform for resource tracking and information sharing.
For example, the United Nations World Food Programme (WFP) has utilised blockchain to distribute cash assistance to refugees, significantly improving efficiency and reducing fraud in aid delivery. This innovation demonstrates the potential for blockchain to enhance transparency and accountability in humanitarian efforts, building trust among donors and recipients alike.
However, scalability and interoperability with existing aid systems remain critical challenges. Addressing these issues will be essential to fully unlocking blockchains potential to revolutionise global partnerships and drive sustainable development.
The Future of Blockchain in Emerging Economies
As we move further into 2025, the focus should be on scaling proven blockchain solutions, investing in necessary infrastructure, fostering global partnerships, and conducting rigorous research to evaluate the impact of these technologies. Emerging economies are demonstrating that with innovation and strategic implementation, sustainable development is achievable and blockchain can play a valuable role in that process.
