There is the first Proof-of-Person Blockchain. No money for stake or equipment needed, just an average laptop.
You can easily join mining of the first human-centric cryptocurrency at idena.io and share your opinion.
It seems like a very unique idea. But what's the utility of this blockchain in real world?
Also I understand a turing code needs to be solved to work as a node in idena network and I also understand that the frequency of solving turing code will reduce as the network grows. What's the current frequency?
Also i see that it is not completely decentralized. Because if I am inviting someone, I will retain the full right to expel that person from the network. Any specific reason for that?
