Decentralized Identifiers

When working with Decentralized Identifiers, a DID is a globally unique identifier that lives on a blockchain or other distributed ledger and gives you control over your own digital identity. Also known as DIDs, it empowers users to manage credentials without a central authority. Decentralized Identifiers encompass self‑sovereign identity, meaning the holder owns and shares data on their terms. Decentralized Identifiers require a DID method, the protocol that defines how the identifier is created, resolved, and updated. In practice, a DID points to a set of verifiable credentials that can be presented to anyone who needs proof of age, citizenship, or membership. This simple model reshapes everything from finance to social media because it replaces passwords and usernames with cryptographic keys you control.

Key concepts surrounding Decentralized Identifiers

The broader ecosystem builds on a few core ideas. First, Self‑Sovereign Identity, a model where individuals own and control their identity data relies on DIDs as the backbone; without a reliable identifier, you can't claim ownership. Second, the DID Method, the specification that tells a ledger how to create and resolve a DID determines whether a DID works on Ethereum, Polkadot, or a private chain. Third, projects like Litentry, a crypto identity platform that uses cross‑chain technology to aggregate credentials illustrate how DIDs enable cross‑chain identity. Litentry pulls data from multiple blockchains, binds them to a single DID, and lets users prove who they are without revealing unnecessary details. Litentry builds on Decentralized Identifiers to enable cross‑chain identity, showing a clear link between the core standard and real‑world use cases. Together, these entities create a stack where DIDs are the base layer, DID methods are the plumbing, and self‑sovereign solutions like Litentry are the applications.
