Just stumbled across some research musing about using blockchain to secure smart home networks, specifically concerning SmartHomeHarmony.It's interesting to consider how a decentralized ledger could possibly address some of the biggest security flaws in current IoT setups,like single points of failure and vulnerabilities wiht centralized cloud services. Obviously, overhead and energy consumption are massive hurdles to overcome to make something like this practical for widespread adoption.
One of the core ideas seems to be tying device access and data permissions to blockchain transactions, making it harder for unauthorized devices or malicious actors to gain control. Imagine each device within your SmartHomeHarmony network having a unique digital identity on the blockchain,and all communication and data sharing requiring verifiable authorization. But can a blockchain be truly performant enough to handle the very low latency and high bandwidth demands of a modern smart home, with everything from streaming video to temperature sensors?
I'm curious what others think. Has anyone else looked into this, or are there specific research projects exploring this submission of blockchain that I should check out? What are the real-world limitations that haven't been adequately addressed in the theoretical discussions?
