Blockchain has the power to change how insurance firms conduct business. Blockchain can help operators to save money and time, improve transparency, abide by rules, and develop better goods and markets. Insurers are inherently competitive in a highly competitive market where both individual and corporate customers expect the highest profitability and a superior online experience. In the insurance sector, blockchain technology represents an excellent transformational and growth opportunity. Insurance can be purchased through a blockchain account, which provides greater automation and a tamper-proof audit trail through the use of smart contracts and decentralised applications on Ethereum. The low cost of smart contracts and associated fees, in particular, means that many items will be more competitive in limited markets in developing countries. Ultimately, the burgeoning blockchain economy will need its own insurance. Cyber insurance covers coverage (technology and software projects) with extensions and approvals for monetary losses (hot wallets and exchanges), species and crime (cold wallets and vaults), professional liability (developers), and guarantors can be used as a template for [1]. This study reveals the most fascinating aspects of blockchain technology that have paved new opportunities for the insurance industry using blockchain technology. This research addresses the use of smart contracts in blockchains, where information is secure and automated so that a specific type of payment contract can be entered into without human intervention. It also discusses the challenges and concerns that insurance companies may have with regard to the use of blockchain technology. Finally, barriers and obstacles to the adoption of blockchain technology in the insurance industry are discussed through a number of case studies
