What do you think is easier: convincing farms to send a cheap message to a federated database when they ship out products, or have them buy up insane quantities of computational power to compute crypto hashes, using insane amounts of power to do it?

Blockchain is crazy expensive to run. Why would anyone pay for that when there's dirt cheap alternatives that are every bit as effective at solving the problem?

who is paying for the federated database? i didn't know there are free ones.do you actually know the cost of an ethereum transaction? I'll help its 0.01$ and you don't have to do it all the time if you just run a side chain
