Zero-Trust Meets Blockchain: A New Framework For Fintech Security? - Forbes

This article explores groundbreaking research on integrating blockchain technology with zero-trust security frameworks to address insider threats and access control challenges in the financial technology sector.

The piece examines how traditional zero-trust security models, while effective at requiring continuous verification of users and devices, still face limitations when managing large-scale financial data and insider risks. The research proposes using Ethereum smart contracts as distributed access control layers, where security policies are embedded directly into blockchain infrastructure rather than relying on centralized systems that can be compromised by insider threats.

• Blockchain-embedded security policies offer transparency, immutability, and granular control over API access in fintech environments
• Regulatory advantages include immutable audit trails and cryptographically enforced policies that demonstrate compliance
• Implementation challenges involve performance limitations, privacy concerns, and integration complexities with existing systems
• Industry momentum shows fintechs already experimenting with tokenized identity systems and decentralized audit trails for enhanced security
