FYI, Blockchain is not the future of crypto, Hashgraph is the future. I am not sure why POTN would waste its money in Blockchain due to the fact there is not enough energy produced in the world to power blockchain as a currency. It requires way to much energy to complete transactions. Many, Many computers and servers required. Hashgraph is still in development, but will be able to handle over 500k worth of transactions using very little energy with far more transactions than blockchain. Blockchain has a niche, but it wont be in cryptocurrencies soon. IMO
I am far from a tech person, but this is about as much as I know. Like I said these statements are my opinion, but backed by some research.
