Everyone is downvoting you cause it makes zero sense to use blockchain to do IOT. IoTA is also largely a scam, the technology doesn't work

View on HN

I once pitched blockchain for an IoT sensor system that I worked on, to detect if messages were dropped. Basically for knowing when you need to figure out a new c for your integrals. I thought it was clever on resource constrained hardware because it required just keeping the previous hash in memory, and nothing needed to be persisted between restarts, and the hashes didn't even need to be secure.

I can't remember why it didn't catch on. I think maybe my mistake was not using the word "blockchain", so it lost out on the inherent sex appeal of the word.

Payment blockchains and IoT on the other hand is where I fail to see the relevance.

I cant seem to edit my comment. I think my comment was misunderstood.

Firstly, I wanted to say that the writer seems biased, and due to this they disregarded the technology of blockchain. They mixed up bitcoin and blockchain and the use cases are completely different things

As for IOTA being a scam. I honestly do not know, I liked their use case but perhaps I am uneducated...If you have any papers or links to back up your claims then please provide them, i'm open to having my opinion changed.

It is true, they are different. Blockchain can be used for many other things than only cryptocurrency (although cryptocurrency is one thing that can use it). A blockchain includes blocks each with the hash of the previous block, and many things do that including Fossil version control system (the P card has the hash of the previous block), and I also had the idea how it could be used for a restricted class of card games, and there are probably many other uses too.

I cannot properly comment about IOTA since it isn't something that I am familiar with.
