I have several questions regarding this Blockchain approach:

1) In blockchain security depends on computing nodes to calculate the
blocks. How do you solve this problem with low-power devices - i.e.
who is calculating the blocks? Is it maybe gateway? I am asking this
because whoever can have big processing power on the network can take
over the whole network.

2) Did you try to leverage existing Blockchains - Bitcoin or Ethereum
ones? I am asking this because I suppose that these networks are now
practically impossible to take over.

3) Did you examine Hyperledger project for the possible use of their
Fabric blockchain?

BR,
Drasko
