Decentralized Identity Management and Blockchain

One approach involves creating digital identities anchored to blockchain, where users control their identity credentials through cryptographic keys. When verifying a phone number, a user can present a digital proof stored securely on the blockchain, eliminating the need for SMS codes or centralized databases.
Smart contracts facilitate automated verification processes, executing phone number list predefined rules without human intervention. For example, a smart contract could automatically validate a user's ownership of a phone number based on cryptographic proof, reducing reliance on third-party verification services and decreasing fraud risk.
Moreover, blockchain can enable real-time, transparent audits of verification activities, enhancing accountability. Users gain greater control over their data, choosing when and with whom to share verification credentials, thereby improving privacy and reducing data exposure.
This decentralized approach also offers resilience against common attack vectors like SIM swapping or data breaches, as the verification proof is stored and validated on a distributed ledger rather than a vulnerable central database.
Decentralized identity (DID) is a core concept underpinning blockchain-based phone number verification systems. It enables individuals to create, manage, and share their digital identities without relying on centralized authorities.
In DID models, users generate cryptographic keys linked to their identity, which is registered on a blockchain network. The identity itself is represented as a set of verifiable credentials—digital attestations issued by trusted entities—stored securely on the blockchain.
