Yes, it is all about IoT. About Ethereum; Have you gotten a good insight in this? I know what a blockchain is, but assuming a million sensor generating 12 values per hour, we are talking GBs per hour of data added... And 1 million is hopefully on the low end.
I would love to hear more about it... Cheers Niclas On Sun, Feb 14, 2016 at 11:55 PM, Jiri Jetmar <[email protected]> wrote: > Hi Niclas, > > so you are hacking now on hardware ? Interesting..
