Challenges and Limitations of Blockchain-Based Verification

[labonno896]

Despite its promising features, blockchain-based phone number verification faces several challenges. Scalability remains a concern, as current blockchain networks can experience congestion and high transaction costs during peak usage.

Interoperability is another issue—different blockchain platforms have varying standards and protocols, complicating integration with existing systems. Developing universal standards for decentralized identity and verification is an ongoing effort.

User adoption and understanding pose hurdles, as blockchain phone number list concepts are complex and require education for widespread acceptance. Additionally, regulatory frameworks around data privacy, digital identity, and blockchain vary globally and can hinder deployment.

Security vulnerabilities, such as smart contract bugs or 51% attacks, can compromise the integrity of verification systems. Ensuring rigorous security audits and best practices is essential.

Finally, legal and ethical considerations around data sovereignty, consent, and user control must be addressed to build trust and compliance with data protection laws like GDPR and CCPA.

Future Outlook and Trends
The future of blockchain-based phone number verification looks promising, with ongoing innovations and increasing adoption across industries. Emerging standards and protocols aim to improve interoperability, scalability, and user experience.
