Important considerations

  • What are Decentralized Identifiers (DIDs)?
    • DIDs are unique global identifiers that allow an entity to control its digital identity without the need for a central authority. They facilitate a more secure and private web.
  • How is a DID structured?
    • A DID consists of three main parts: the scheme (always did:), the DID method (which indicates the specific technology or protocol used), and the DID’s unique identifier.
  • What is a DID Document?
    • It’s a JSON document containing information associated with a specific DID, including public keys, services, and other metadata necessary for secure interaction in digital environments.
  • What are the fundamental principles of DIDs?
    • DIDs are based on principles of decentralization, interoperability, security through cryptographic proofs, and user control over their own identity.
  • How do DIDs work for authentication and identity verification?
    • DIDs enable identity verification through cryptographic technology and distributed ledgers, eliminating the need for intermediaries in the authentication process.
  • What are DID methods?
    • DID methods are a set of rules and procedures that define how DIDs are created, resolved, and managed within a specific system or technology.
  • What is the difference between a subject and a controller in the context of DIDs?
    • The subject is the entity identified by the DID, while the controller is the entity with permissions to modify the subject’s DID Document.
  • What role do resolvers and registries play in the DID ecosystem?
    • Resolvers are tools that allow obtaining the DID Document from a DID, and registries are systems that store and allow the management of DIDs and their associated documents.
  • How are DIDs created?
    • DIDs are created using a specific DID method, following the rules and procedures defined for that method, and are usually registered in a distributed ledger system like blockchain.
  • How is the security and privacy of DIDs ensured?
    • Security is ensured through the use of advanced cryptography, and privacy is assured by allowing users to control what information they share and with whom, using selective data disclosure.
  • Can DIDs be used by organizations, devices, or applications?
    • Yes, DIDs can identify not only individuals but also organizations, devices, and applications, offering a wide range of applications in different contexts.
  • What practical applications do DIDs have?
    • DIDs have applications in authentication, digital signing, identity management, permission systems, and any scenario requiring secure and verifiable identification.
  • What is the future of DIDs?
    • DIDs are expected to play a crucial role in the development of a more secure and privacy-oriented internet, promoting the adoption of decentralized digital identities across various sectors.
