Abstract
The Nigerian insurance industry continues to experience low penetration, limited public trust, operational inefficiencies, and persistent fraud challenges, all of which hinder its contribution to national economic growth. Emerging digital innovations particularly block chain technology, present new opportunities to address these structural weaknesses. This study appraises the role of block chain technology in enhancing the growth of insurance business in Nigeria. The paper adopts a qualitative research design based on an extensive review of secondary data, including scholarly literature, industry reports, and selected international and African case studies. The study examines the application of block chain in fraud prevention, automated claims processing, customer identity management (KYC), reinsurance transparency, and micro insurance expansion. Evidence from global implementations indicates that block chain improves transparency, reduces operational costs, enhances customer trust, and increases administrative efficiency through smart contracts and decentralized record-keeping systems. However, the study identifies major barriers to adoption in Nigeria, including high implementation costs, regulatory uncertainty, infrastructural deficits, and limited technical expertise. The paper concludes that while block chain adoption in Nigeria’s insurance sector is still at an emerging stage, its strategic integration could significantly enhance operational performance, financial inclusion, and long-term industry growth. The study recommends the development of a clear regulatory framework, industry-wide collaboration, and capacity building to facilitate sustainable block chain integration in the Nigerian insurance market.
