TangleID

Introduction

TangleID is a secure, easy-to-use system for self-sovereign identity, built on IOTA/Tangle. An identity can be cryptographically linked to offline data stores. Each identity is capable of storing the hash of an attributed data blob, whether on Google Cloud, Azure, AWS, Dropbox, etc., which is where all data associated with that identity is securely stored.

Identities are capable of updating this file themselves, such as adding a profile photo or a friend, or they can also grant others temporary permission to read or write specific files. Since they can interact with Tangle network, TangleID identities can also control digital bearer assets such as cryptocurrencies or other tokenized assets.

Use Case

• End-user

TangleID allows end-users to: own and control their personal identity, reputation, data, and digital assets; securely and selectively disclose their data to counterparties; access digital services without using passwords; digitally sign claims, transactions, and documents; control and send value on a Tangle; interact with decentralized operation logic; and encrypt messages and data.

• Enterprise

TangleID allows enterprises to: establish a corporate identity; easily onboard new customers and employees; establish an improved and transitive Know-Your-Customer (KYC) process; build secure access-controlled environments with less friction for employees; reduce liability by not holding sensitive customer information; increase compliance; maintain a network of vendors; establish role-specific, actor-agnostic identities with specific permissions.

Functionality

TangleID, an identity system, aims to be a flexible and easy-to-use method of interacting with decentralized applications as well as off-Tangle identity related tasks by abstracting away the public key cryptography from the end user to make the user experience intuitive.

A mobile app holds the user's private key and a certain address acts as their identifier. We use a novel identity recovery mechanism to let the user select friends from their contact list which gives a quorum of these friends the ability to recover the identity of the user if their mobile device is lost.

Get started

Setup environment

TangleID depends on swarm node to accelerate the interaction between API calls and IRI nodes. Therefore, you shall configure the swarm node host in advance.

• Create new file named .env and specify IRI_HOST, SWARM_HOST and API_HOST
  • IRI_HOST: an address (IP or domain) to the IRI node.
  • SWARM_HOST: an address (IP or domain) to the swarm node that accepts TangleID extension.
  • API_HOST: main entry point for the API that TangleID invokes on client side.

Default host-specific configurations:

IRI_HOST=http://node1.puyuma.org:14266
SWARM_HOST=http://node2.puyuma.org:8000
API_HOST=http://localhost:3000/api

You can modify these entries in file .env accordingly, but please note that the default environment runs on testnet.

Run TangleID

Build TangleID from scratch:

$> npm install

Launch TangleID service, for either development or production build:

• Development build

  $> npm run dev

• Production build
