"Well use smart contract transactions to secure all internal communications within your home system."
- so, if I'll ask 'Alexa, make a coffe', I'll have to wait 25 minutes until transaction mined and confirmed?
Will I have to pay a transaction fee for this as well?
i dont think it will take long time confirmation, since there are blockchain like ethereum that produce block every 15 second.
and, devs will not use blockchain that need more than a minute confirmation for this
