Decentralized insurance on blockchain can gain mainstream trust by leveraging transparency, immutability, and smart contracts. These ensure verifiable, tamper-proof policies and automated claims processing, reducing reliance on intermediaries. However, challenges like complex user interfaces, regulatory uncertainty, and limited understanding of blockchain technology hinder adoption. To build trust, platforms must prioritize user-friendly designs, robust security, and clear communication of benefits. Partnerships with established insurers and compliance with regulations can further enhance credibility. As education and infrastructure improve, decentralized insurance has the potential to become a trusted alternative for mainstream users.
