I am currently working on an IoT network that will be secured by using blockchain.
The idea is that the IoT sensing device will be simulated with an Arduino Uno.
The Arduino will aggregate location data every hour and sent this to a cloud server.
The cloud server and applications will be secured by using blockchain. However, I was wondering if someone knows if the Arduino itself can also be secured with blockchain?
How does this work? Since an Arduino itself does not have enough computational power.
I do not have any experience at all with arduino and designing a IoT network. I hope that someone can help me a bit!
Yes, it is. We are trying to find a way to prevent attacks on IoT devices (in this case an Arduino).
For all other nodes in the network, authentication and access control will be performed by using blockchain technology.
We thought that this might be possible for an Arduino as well, but I can not find any information on this.

It doesn't work, for the reason you have given.
I am reminded of a story a friend told me a long time ago in the age of dial up modems. Someone he knew said they could hack into any computer, so my friend challenged this guy to hack into his computer. After a week of trying this guy said to my friend "you don't have your modem connected do you?". "No", said my friend.
Why am I telling you this? Because you said you are using a Uno. A Uno can't be hacked in for the same reason my friends computer couldn't be.
