did:web

Specification: https://w3c-ccg.github.io/did-method-web/

The did:web method allows domain name owners to express Decentralized Identifiers (DIDs) and DID Documents in a manner compatible with the existing web architecture. It directly derives DIDs from domain names, using standard HTTP protocols for resolution.

Advantages

• Web-Native: As it's designed to be compatible with the existing web architecture, the did:web method is easier to use and understand for developers already accustomed to web technologies.

• Interoperability: This method works seamlessly with existing web infrastructure, ensuring smooth integration and operation.

• Non-Blockchain Based: The did:web method does not rely on a blockchain, thus it circumvents potential scalability issues and transaction costs that blockchain-based systems may encounter.

Disadvantages

• Centralization: The did:web method's reliance on domain names introduces a degree of centralization into its operation. This is because domain names are typically managed by centralized entities, which somewhat contradicts the decentralized ethos of DIDs.
