Manage Device Identity and Binding with W3bstream

This tutorial demonstrates how to manage device identity and device binding within a DePIN application powered by W3bstream Devnet.

Build a full-stack dApp on Trusted Location

Injecting trusted location data into dApps opens the door to several new types of applications. The dapp we're going to build allows users to create location-based Airdrops that can be unlocked only by those devices that were within the specified location area of the Airdrop during the time range determined by the Airdrop's creator.

Enable Trusted geo-location on your Smartphone

This tutorial shows how to enable trusted geo-location data in ioPay Wallet.

A Blockchain Powered Smart-Lock with Arduino Nano IoT 33 (Part 2)

A Blockchain Powered Smart-Lock with Arduino Nano IoT 33 demonstrated how to remotely control a home automation device using a smart contract. With this tutorial we'll be adding a new feature to our project: A button that will change the status of the lock and update the smart-contract accordingly.

A Blockchain Powered Smart-Lock with Arduino Nano IoT 33 (Part 1)

This tutorial demonstrates how to remotely control a home automation device using a smart contract. We will be controlling a smart-lock through the popular Arduino Nano 33 IoT, which will be connected to the IoTex blockchain.

Deploy an ERC20 Token on IoTeX using Truffle

Learn how to deploy a mineable / burnable ERC20 token on the IoTeX blockchain using Truffle

How to run a IoTeX Full Node on a Raspberry Pi Board

While many people think that running a blockchain full-node is all about mining, there are actually other reasons why you may want to run a full-node. For example, it can be a very effective learning experience that allows you to see first-hand how blockchain works. But there is another important reason why you may want to run your own blockchain full-node, especially if you are trying to connect IoT devices to the blockchain: that's when you need a "Blockchain Gateway", a full-node whose only purpose is to provide clients access to the blockchain.
