[Tabular-Iceberg]

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.
