Package Exports

tydids-p2p
tydids-p2p/TydidsP2P.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (tydids-p2p) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

tydids-p2p

A consensus driven decentralized data governance framework.

Installation

Use on CLI

npm i -g tydids-p2p

tydids -h

Use as Module

npm i -s tydids-p2p

Node

const tydids = require("tydids-p2p");

// Get a new privateKey (Step 0)
const wallet = tydids.ethers.Wallet.createRandom();
const privateKey = wallet.privateKey;  // save this key! if not - you will get a new random one each time!

// Initialisation and get SSI Object
const ssi = await tydids.ssi(privateKey);

API / Usage

Create Private Key (SSI)

Each self sovereign identity needs to have a private-key. So any usage/function starts with requires it.

Shell / CLI

tydids --createPrivateKey
0x62c3e5c1906d6e19e35e6fc1575dde0bc9bc5bc0c1ea84caf84b371a4bc00dca

tydids --
priv 0x62c3e5c1906d6e19e35e6fc1575dde0bc9bc5bc0c1ea84caf84b371a4bc00dca --identity -x

Node

const wallet = tydids.ethers.Wallet.createRandom();
const privateKey = wallet.privateKey;
const ssi = await tydids.ssi(privateKey);
console.log(ssi.identity);

Note: For better readability private-key (eq. init of SSI) is implicit on the other examples. So in console/shell always add --priv argument. In your code do const ssi = await tydids.ssi(privateKey);.

Retrieve a public presentation

Shell / CLI

tydids --presentation 0x8b77634AE6D170C34657880fF1eAC9Aaf566Fd1E -x

{
  iat: 1644793815,
  id: 'did:ethr:6226:0x8b77634AE6D170C34657880fF1eAC9Aaf566Fd1E',
  address: '0x8b77634AE6D170C34657880fF1eAC9Aaf566Fd1E',
  publicKey: 'be2ad6f7a6ca94cf1682d8c5ac8a98cfc208c62da6289fd2a9ea68841f69a39e945aab35a0752c24a252bdab81b742669e21daae04a228d5ab2941beda8bcf91',

  hello: 'world',
  ...
}

Note: parameter -x allows to quit/exit directly after receiving the did. Not listening to updates.

Note: You might store your privateKey in a .tydids.json as like {privateKey:'YOUR-KEY-HERE'}

Node

let presentation = await ssi.retrieveVP(address);
console.log(presentation);

Create a new presentation

Will be owned by SSI and will have a unique ID (address).

Shell / CLI

tydids --createPresentation -x

{
  id: 'did:ethr:6226:0xb80A4B2E0CC4d51cC6365eB5B12523730fC7bb04',
  address: '0xb80A4B2E0CC4d51cC6365eB5B12523730fC7bb04',

  creator: '0x5Cb08Dec0595671E2C1f45Da3BbBF6f75ED3F4C7'
}

Node

let presentation = await ssi.createManagedPresentation();
console.log(presentation);

Set field/attribute of presentation with value

In order to change a value SSI needs to be either owner or delegate.

Shell / CLI

tydids -x -p 0xb80A4B2E0CC4d51cC6365eB5B12523730fC7bb04 -s key1 value1

tydids -x -p 0xb80A4B2E0CC4d51cC6365eB5B12523730fC7bb04

{
  iat: 1644885295,
  id: 'did:ethr:6226:0xb80A4B2E0CC4d51cC6365eB5B12523730fC7bb04',

  iss: 'did:ethr:6226:0xb80A4B2E0CC4d51cC6365eB5B12523730fC7bb04',
  key1: 'value1'
}

Node

let presentation = await ssi.retrieveVP(address);
presentation[key] = value;
await ssi.updateVP(address,presentation);
