I'm not sold on why Internet of Things technologies need a distributed ledger system. Devices already upload data streams to predesignated servers, but why would it need a distributed ledger system? Distributed ledger systems are good for certain things, but not everything. This is something we've been seeing quite often - blockchain technology "companies" trying to blockchain everything. Don't be surprised when these "blockchain" companies that promise to be the solution to X problem in Y industry screw investors over and fail to provide viable products as promised.
In the article 3 main points are listed:
-Blockchain needs good IoT for industrial and logistic applications, such as proof of provenance.
-IoT has centralized infrastructure now, but in the future it could be decentralized becoming more safe and resilient. The servers are single points of failure right now.
-Security in IoT
I understand your point, but the question I'm wondering about is - does IoT
NEED blockchain technology? With exponential rise in the number of IoT devices in various industries and sectors in the coming years, what purpose does the public availability of all transactions recorded onto some distributed ledger serve? I'd love to hear out some specific examples, but I'm really not an IoT engineer to elaborate anymore on my points. (I only know a bit about smart metering technologies haha)
