Ethereum is mentioned, because it has Dapps (iirc). But I don’t think you necessarily need the monetary part in order to use the blockchain to store stuff and execute procedures as a reaction to certain values. That’s what I think “smart contracts” are. I remember that IOTA has a similar function and you can send zero value entries, specifically to communicate between low power iot devices. If you really need a blockchain for most applications is a different topic though.
