I ran through these instructions
https://sovrin.org/wp-content/uploads/Token-Test-Instructions.pdf

I used Ubuntu 16.04 running from Virtualbox. All seemed fine until I got to this instruction:

ubuntu@ubuntu:~$ sudo apt-get install -y indy-cli libsovtoken
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 indy-cli : Depends: libindy (= 1.15.0)
 libsovtoken : Depends: libindy (>= 1.14.0)
E: Unable to correct problems, you have held broken packages.

I found: https://lib.rs/gh/hyperledger/indy-sdk/libindy
(however, I did not find that it was up to date?)

I found this: https://github.com/hyperledger/indy-sdk
and this: https://github.com/hyperledger/indy-sdk/blob/master/docs/how-tos/write-did-and-query-verkey/README.md

I need to also install this for the rest of ubuntu-build to work:

sudo add-apt-repository "https://packages.ubuntu.com/xenial/amd64/libzmq3-dev/download" in 

https://packages.ubuntu.com/xenial/amd64/libzmq3-dev/download

sudo add-apt-repository 
"deb http://cz.archive.ubuntu.com/ubuntu xenial main universe"

sudo apt-get install cargo


----
I think that this needs libindy installed first:

This seems to be a hassle. I ran out of memory on my virtual machine and it took forever to complete the steps.

How about trying docker???

DID document to try

 DID document to try:

{
  "@context": "https://www.w3.org/ns/did/v1",
  "id": "did:example:F9C36F8964623378BDC068D4BCE07ED17C8FA486F9AC0C2613CA3C8C306D7BB6",
  "authentication": [{
    


    "id": "did:example:F9C36F8964623378BDC068D4BCE07ED17C8FA486F9AC0C2613CA3C8C306D7BB#keys-1",
    "type": "JsonWebKey2020",
    "controller": "did:example:F9C36F8964623378BDC068D4BCE07ED17C8FA486F9AC0C2613CA3C8C306D7BB6",

    "type": "VerifiableCredentialService",
    "serviceEndpoint": "https://example.com/vc/"
  }]
}

Possible Workflow. Create DID document with public key,hash with sha256, sign with the private key.
Send signed DID document and unsigned DID document to register with the service endpoint. Use the DID document
to get the public key to decrypt signed messages.

-----------------------------------------------------------------------------------------------------

Create a sha256 hash of this DID document. Sign the sha256 hash with the private key.
Compare the unsigned hash with the signed hash. (like you did with the message).
Figure out DLT later. I am not sure why BigChainDB isn't working.

Can I advertise my DID with the device to look up my public key? Is that how it works?


Can I list my DID based on a P-256 key on a public ledger created with Ed25519 keys?

Perhaps it looks like this:

{
  "@context": "https://www.w3.org/ns/did/v1",
  "id": "did:example:F9C36F8964623378BDC068D4BCE07ED17C8FA486F9AC0C2613CA3C8C306D7BB6",

    }
  }],

}

Possible Workflow. Request Ed25519 key from another device, Put Ed25519 key in DID document along with P-256 key.
Sign the document with P-256 private key in program on edge device. Put the DID document on ledger with the Ed25519 key.
