Example

Example code:

URI did = URI.create("did:ex:1234");

Service service = Service.builder()
        .type("ServiceEndpointProxyService")
        .serviceEndpoint("https://myservice.com/myendpoint")
        .build();

VerificationMethod verificationMethod = VerificationMethod.builder()
        .id(URI.create(did + "#key-1"))
        .type("Ed25519VerificationKey2018")
        .publicKeyBase58("FyfKP2HvTKqDZQzvyL38yXH7bExmwofxHf2NR5BrcGf1")
        .build();

DIDDocument diddoc = DIDDocument.builder()
        .id(did)
        .service(service)
        .verificationMethod(verificationMethod)
        .build();

System.out.println(diddoc.toJson(true));

Example DID document:

{
  "@context" : "https://www.w3.org/ns/did/v1",
  "id" : "did:ex:1234",
  "verificationMethod" : {
    "type" : "Ed25519VerificationKey2018",
    "id" : "did:ex:1234#key-1",
    "publicKeyBase58" : "FyfKP2HvTKqDZQzvyL38yXH7bExmwofxHf2NR5BrcGf1"
  },
  "service" : {
    "type" : "ServiceEndpointProxyService",
