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.

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.
