This would be the most detailed and technical section of the article, outlining how a blockchain-based system for phone number management would function in practice:
- The User’s Perspective: The article would describe how a user would create a DID using a secure digital wallet on their smartphone. This wallet would be the central point of control for their introducing blockchain as a foundational solution digital identity, including their phone number.
-
Onboarding and Linking a Phone Number:
- The process of associating a new or existing phone number with a DID would be detailed. This would likely involve phone number list the telecom provider issuing a VC to the user’s DID after verifying their identity through traditional means (initially).
- The End of SIM Swapping: A step-by-step walkthrough of how the new system would prevent SIM swapping would be a key focus. For example, to provision a new SIM, the user would have to cryptographically sign a request with the private key associated with their DID. A telecom employee would not be able to override this, making social engineering attacks futile.
-
Secure and Consensual Number Porting:
- The process of moving a phone number to a new carrier would be managed through a smart contract on the blockchain. The user would initiate the porting request from their wallet, and the old and new carriers would update the associated VCs on the blockchain, with the user’s explicit cryptographic consent.
-
Enhanced Privacy through Multiple DIDs:
- The article would explore how users could have multiple DIDs for different areas of their life (e.g., one for work, one for personal use, one for online shopping), all potentially linked to the angola lists same phone number but kept separate to prevent correlation.
- The Potential for Truly Private Communication: The article would touch on the possibility of using DIDs as the basis for end-to-end encrypted communication, where the public phone number is merely a pointer to a secure, decentralized identifier.
