I have been trying to even get that far for a while now, but always get a bad request. I followed the example on https://didproject.azurewebsites.net/docs/overview.html but I think it is out of date. I have the ion node up and running but I am stuck with the create part. Maybe If you have some time we can collaborate on a create walkthrough PR.

I did a bit more testing on this today, and it seems that older transactions have a different format to the anchorFile, that is, they contain an didUniqueSuffixes property:

{
    "batchFileHash": "EiAWU0PAu-anVbqXrGLoU3Gd26KPRx70YFd6wV-lnpfSuw",
    "merkleRoot": "CN8pvEAsD35vYxh2y-x4FXIvjoboGKpo401YxGbWvYE",
    "didUniqueSuffixes": [
      "EiBR8vuOtZrHqf_reS7GENZF_ertBlozTC-gXAHrTieNOA",
      "EiC7LUJu6IWvpp1_RGIsTMUXlMj21yhK9bWPKZ-r8S54MQ"
    ]
  }

That would answer my initial question, in as far as, it would explain how to resolve the DIDs relating to the operations in the batch file.

However...

The batch files for those older transactions, (any transaction with the "didUniqueSuffixes" property) seem to be missing. I'm just getting a 404 when trying to request them from the CAS endpoint.

Why are those batch files missing? Is it just down to anomalies of a the test network? Perhaps the batch files were not cached or pinned anywhere and the originals have gone?

Also, and more importantly, how can there be sidetree transactions with no didUniqueSuffixes - surely this is incorrect?

By any chance are you able to create DID's?

orbmis commented on June 18, 2024

Yes I'm able to create a DID, although there is a bit of a delay when trying to resolve the newly created DID from the ION node.

This is the js I am using to make the JWT

async function makeJws() {

    // construct the JWS payload
    const body = {
        "@context": "https://w3id.org/did/v1",
        publicKey: [
            {
                id: jwkPub.kid,
                type: "Secp256k1VerificationKey2018",
                publicKeyJwk: jwkPub,
                "usage": "signing"
            },
            {
                id: jwkPubRecover.kid,
                type: "Secp256k1VerificationKey2018",
                publicKeyJwk: jwkPubRecover,
                "usage": "recovery"
            }
        ],
        service: [
            {
                id: "IdentityHub",
                type: "IdentityHub",
                serviceEndpoint: {
                    "@context": "schema.identity.foundation/hub",
                    "@type": "UserServiceEndpoint",
                    instance: [
                        "did:test:hub.id",
                    ]
                }
            }
        ],
    };

    // Construct the JWS header
    const header = {
        alg: jwkPub.defaultSignAlgorithm,
        kid: jwkPub.kid,
        //operation:'create',
        //proofOfWork:'{}'
    };

    // Sign the JWS
    const cryptoFactory = new didAuth.CryptoFactory([new didAuth.Secp256k1CryptoSuite()]);
    const jwsToken = new didAuth.JwsToken(body, cryptoFactory);
    const signedBody = await jwsToken.signAsFlattenedJson(privateKey, {header}.Protect);
    //const signedBody = await jwsToken.Protect.sign(privateKey, {header});

    // Print out the resulting JWS to the console in JSON format
    console.log(JSON.stringify(signedBody));

I'm also struggling to create a DID using the information on the Sidetree Protocol Specification. So far I have documented my steps here: https://github.com/OwnYourData/did-ion
Would love to join a collaboration to create a walkthrough!

Dinglebarry9 commented on June 18, 2024

@fabianekc, Yes totally I will pull your repo and add some stuff.

orbmis commented on June 18, 2024

Seeing as this issue was originally opened with regards to missing DIDs in the anchor files, I'm going to close it for now, and I will try to resolve the issue offline. I'm happy to help with the issue of creating a DID using ION, and to contribute to some documentation, but lets do it under @fabianekc 's project for now.

Dinglebarry9 commented on June 18, 2024

@SimBro one question, what is "did:test:hub.id", do you host it yourself or is it somewhere else, I don't know where to start, all the decentralized-identity repos that concern identity hubs are depreciated.

Is it possible to get the DID of each operation in the batch file? about ion HOT 9 CLOSED
