Full Title or Meme

One brand of Decentralized ID (DID) originated by Microsoft based on a high performance side tree.[1]

Context

Every one knows the problem with identities on the internet. They are not under the control of users, who are extremely interested in their own Identity and want their own Privacy.

Problems

  • The big problem is Trust where there are no standards or examples of any trust without a history of trusted behavior.
  • Proof of Persistent Identity must be provided. This can be little more than the inclusion of a public key in a block chain, but that cannot provide any Assurance of protection of the Credential.
  • Most "pure" Blockchain solutions require more energy or time that is appropriate for a user on a Smart Phone.

Solutions

  • Side chains are one solution to the time and energy requirement for a full Blockchain ID solution. Ion ID is one implementation of sidechain.
  • A test registration for an Ion ID is here. "In order to complete this registration tutorial, you'll need NPM and NodeJS 8 or later installed on your machine."
  • The file to load for json is on GitHub. The following (on 2019-05-23) shows those instructions run from PowerShell in system32, that is definitely not a "best practice".
PS C:\WINDOWS\system32> npm install @decentralized-identity/did-auth-jose@0.1.12

PS C:\WINDOWS\system32>
  • the file "package.json" is on the gibhub repo. I guess it needed to be copied down first?
  • Generate keys
PS C:\WINDOWS\system32> node generate-keys.js
(node:17228) [DEP0010] DeprecationWarning: crypto.createCredentials is deprecated. Use tls.createSecureContext instead.

PS C:\WINDOWS\system32>
  • Get a json web token (JWT) to be signed into a signed JWT, or a JWS
