Thank you so much for participating amincd!
I wasn't able to understand how your proposed "Proof of Presence" system would work. Given there's no way to identify the creator of a block, there would be no way to know when consecutive blocks are created by single party. If you can explain how other network participants would know who is creating the blocks, I would appreciate it.
Please bear with my limited understanding.
As I understand, it can be determined who mined a block by the address used for the fee & reward payments, and this is how Proof of Stake is enforced. If this is not correct, please educate me on how Proof of Stake is enforced.
I realize that a miner/pool can use multiple addresses and would love advice on how to thwart that as well, but at least the cost to attack with secret chains is increased by some amount, I assume.
Thank you so much in advance for your knowledge!
