Abstract

The research presents a blockchain-based identity management system for protecting decentralized web applications by operating through decentralized processes. Through its permissioned Ethereum network The-system enables automatic operations for identity lifecycle management to register authenticate authorize and revoke users while maintaining privacy of user data (anonymization and encryption of user data). Users receive hashed credentials which the blockchain ledger retains forever as secure storage alongside complete PII data privacy. Smart contracts determine access through comparison between incoming requests and permanent role statements stored on the blockchain network. Large attribute storage operates by connecting to Inter Planetary File System (IPFS) gateway servers that store blockchain reference data through content hash keys. Users accomplish authentication via a zero-knowledge proof module which enables attribute disclosure under zk‑SNARK’s parameters to reduce identity exposure. The consensus model deployed in the system supports execution of more than 5000 TPS transactions by completing them within sub-second periods. Performance evaluation confirms scalability, reliability, and real-time access control, demonstrating its viability for modern web applications requiring high throughput and low-latency operations. Security testing establishes that the network withstands Sybil attacks together with replay and man-in-the-middle attacks and privacy evaluation demonstrates unauthorized entities have no ability to derive user profiles. The evaluated benchmark results demonstrate that the framework’s performance potential by testing 50 nodes in a test network locally. Research indicates that blockchain identity management develops an resistant system which has enormous potential capacity alongside privacy protection capabilities superior to conventional centralized identity management systems.
