Identifiant Décentralisé (DID)
Identité numérique souveraine.
DIDs are a foundation for 'Self-Sovereign Identity' (SSI). Unlike traditional IDs (like emails or usernames) that are owned by a central company, a DID is created and controlled entirely by the individual. It allows you to prove your identity across many different platforms without relying on a single 'Log in with Google' button.

🧒 Explique-moi comme si j'avais 5 ans
Imagine if instead of having different library cards and gym memberships, you had one magic ID card that you made yourself. No one can take it away from you, and it works everywhere to prove who you are without revealing your personal secrets.
🤓 Expert Deep Dive
A DID consists of a URL with a specific scheme (e.g., did:ethr:...). It resolves to a DID Document which contains public keys and service endpoints. This allows for 'cryptographic proof of ownership' of an identity.
