Register an Identity

Establish an Identity on Dash Platform

The purpose of this tutorial is to walk through the steps necessary to register an identity.

Overview

Identities serve as the basis for interactions with Dash Platform. They consist primarily of a public key used to register a unique entity on the network. Additional details regarding identities can be found in the Identity description.

Prerequisites

• node.js (v12+)
• Basic familiarity with JavaScript asychronous functions using async/await
• The Dash JavaScript SDK is initialized (covered in Connecting to EvoNet)
• A wallet mnemonic with some funds in it: How to Create and Fund a Wallet

Code

🚧

Identity public key reuse

Early versions of Dash Platform did not check if a public key was already used when creating an identity. As of Dash Platform Protocol v0.13, validation ensures that a public key can only be associated with a single identity.

JavaScript

const Dash = require('dash');

const clientOpts = {
  network: 'evonet',
  wallet: {
  	mnemonic: 'a Dash wallet mnemonic with evonet funds goes here',
  },
};
const client = new Dash.Client(clientOpts);

const createIdentity = async () => {
  return client.platform.identities.register();
};

createIdentity()
  .then((d) => console.log('Identity:\n', d.toJSON()))
  .catch((e) => console.error('Something went wrong:\n', e))
  .finally(() => client.disconnect());

The Identity will be output to the console. The Identity will need to have one confirmation before it is accessible via client.platform.identity.get.

👍

Make a note of the returned identity id as it will be used used in subsequent tutorials throughout the documentation.

What's Happening

After connecting to the Client, we call platform.identities.register. This will generate a keypair and submit an Identity Open Transaction. After the Identity is registered, we output it to the console.
