ThreeFold Chain

Introduction

ThreeFold blockchain (aka TFChain) serves as a registry for Nodes, Farms, Digital Twins and Smart Contracts. It is the backbone of ZOS and other components.

Create a TFChain twin

A twin is a unique identifier linked to a specific account on a given TFChain network. Actually there are 2 ways to create a twin:

• With the Dashboard
  • a twin is automatically generated while creating a TFChain account
• With the TFConnect app
  • a twin is automatically generated while creating a farm (in this case the twin will be created on mainnet)

Get your twin ID

One can retrieve the twin ID associated to his account going to Developer -> Chain state -> tfgridModule -> twinIdByAccountID().
