I have been following koinos from the sidelines, and this is the first time I understand the Proof of Burn concept and the burn to mine.

It is an interesting concept, although I'm curious what is the math behind it?
I guess all the inflation goes to miners, so if there is a small amount/share burned for mining at the beginning, the APR for the first miners will be high ... as more come along it should go down. The comparison with Bitcoin miners is not a 100%, since you can sell the miners. Can you sell the virtual hash power? Is it transferable? Maybe the account that has that hash?

Also not a lot is mentioned about scalability here. I know there was talks that it is scalable. What is the block size? What are the technical requirements to run a miner, beside the tokens?

Thanks for the grounded explanation :)
