Sustainable development, or sustainability, refers to meeting the needs of the present generation while not compromising on the needs of the future generation. Cyberspace has increasingly become a tool for actualizing sustainable development, given the increased volume of online transactions. However, cyberspace has equally been used to perpetuate crime and criminality, culminating in high levels of corruption in society. Corruption thrives in secrecy in governance, weakens state institutions, and promotes injustices in society, making the actualization of Sustainable Development Goal 16 (SDG 16) a mirage. Since SDG 16 is the cornerstone for the actualization of the remaining 16 SDGs, this vision paper proposes a blockchain-based cybersecurity system for engendering transparency and accountability in governance, using Nigerian politics as a case study. We used use case diagrams and n-tier component diagrams to explain how the functionalities of blockchain technology can be used to address trust deficits occasioned by crime and criminality. We also harped on how the implementation of the proposed system can impact the attainment of the SDGs by the target year of 2030.
