Regarding the linked blog article that the "attacker" provided in the quote in which he explains that altcoins which employ proof-of-work are impossible to secure, he is not aware of my solution to that dilemma. And that is unprofitable proof-of-work as a matter of protocol forced on payers and changing the proof-of-work algorithm such that ASICs can't obtain orders-of-magnitude improved efficiency over CPUs. There are other details and advantages over the centralized clusterfuck BitCON.

If the "attacker" is really serious about changing the world, he should stop talking to Blockstream and start talking to me.
