When you hear Identity Management, the set of processes and technologies that let people prove who they are online, you might picture a login screen or a government ID. In reality, the landscape now includes Decentralized Identity (DID), a self‑controlled digital identity built on cryptographic keys and blockchain records, also known as self‑sovereign identity. This contrasts sharply with Traditional Identity Systems, centralized databases that store personal data in a single authority, which often suffer from data breaches and limited user control. To make DID work, you need a Digital Wallet, a software container that holds cryptographic keys and verifiable credentials, sometimes called a crypto wallet. All of this runs on Blockchain, a distributed ledger that offers immutable, tamper‑evident records for identity data. In short, Identity Management encompasses Decentralized Identity, relies on Digital Wallets, and is powered by Blockchain, while standing apart from Traditional Identity Systems.
A deep dive into DID standards, protocol layers, cryptographic features, and real‑world applications that enable self‑sovereign identity on blockchain.
Explore the core differences between Decentralized Identity (DID) and traditional identity systems, covering security, privacy, implementation, and future trends.
