How DIDs Work

At its core, DID technology empowers users to generate their own digital identity independent of third parties. This identity is linked to a unique digital identifier that resides on a
blockchain—a decentralized and secure digital ledger.

Here, entities such as individuals, communities, and organizations can authenticate themselves, demonstrate ownership, and oversee their DIDs through a decentralized public key infrastructure (PKI). This system diverges from the conventional web PKI by not depending on centralized certificate authorities (CAs) for its foundational trust.

When you need to verify your identity, instead of submitting sensitive information directly, you use this unique identifier. Your identity details are securely stored on your device, and only you can decide which pieces of information to share and with whom, thanks to a set of cryptographic keys unique to your DID.
