DID resolution
The process of dereferencing a DID to its DID document — the algorithm for following the identifier to its canonical keys and services.
DID resolution is the algorithm that turns a DID into a DID document. The algorithm is method-specific: did:web resolves via HTTPS GET, did:key resolves by decoding the multibase-encoded public key, did:ion resolves via a Sidetree protocol on Bitcoin, did:cheqd resolves by querying the Cheqd ledger.
The W3C DID Resolution specification defines the interface — input: a DID, output: a DID document plus metadata (when the document was last updated, deactivation status, etc.). Universal resolvers implement multiple methods behind one API, so a verifier can hand in any DID and get back the document regardless of method.
LearnCoin credentials reference did:web:learncoin.me, which any standards-compliant resolver (including universal resolvers hosted by DIF, W3C, and others) can dereference to our /.well-known/did.json. Verification doesn't require resolving through a specific resolver — the did:web method spec is a trivial HTTPS GET, and most verifier libraries implement it directly.
