Won’t you like a smart coffee maker that prepares the perfect coffee for you as soon as you wake up or a microwave that can differentiate between a perfectly cooked pizza from a burnt pizza or a smart air conditioner that can send a maintenance service request on its own in case it breaks down. All of this sounds exciting, right? Many of you might assume it to be a thing of the future but this technology - the Internet of things or IoT - has arrived and is staring right in our faces. It is just a matter of some more time before it gets adopted on a mass level.

Smart homes or IoT-enabled homes, where smart devices can talk to each other, are soon going to take over our traditional homes. So it is very crucial that a safe, flexible, and robust method be explored to make IoT more user-friendly and reliable for the owners of these future smart homes. In these super-connected homes, there will be many situations where you will want to give limited access instead of complete access to your home to the other party. For example, when you hire a pet sitter for paying a half an hour visit to feed and look after your dog. In such a situation, you would want him to access your lobby only and not the entire house.

In today’s IoT-enabled smart homes, this pinpoint access is not feasible. We can give complete access to our home to the sitter through our mobile app but we can’t choose what devices or services he can access and what devices and services should be kept off-limits for him.

But with blockchain technology, this is feasible. A blockchain-powered smart home will give more power, and flexibility to the user.
