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.
