This will be my last post in this thread because you just don't get it or don't want to get it. I've made my points very clear several times. Not saying I'm infallible but we aren't moving forward with a productive discussion.
As I already explained, if he sends coins to himself using an attack chain, and the chain is not accepted by the rest of the network , then nothing has changed in his UTXOs, including the stake age, thus allowing him to try again and again until that chain or another chain is accepted.
Those are my criticisms...you had an ample opportunity to address them. The white paper and yourself
seem to miss these known issues with PoS.
Nothing really new here and nothing to prove " Proof-of-stake is more decentralized, efficient and secure than PoW".
Since this doesn't appear to be clear, we'll be updating the white paper with a more detailed explanation of why the attack you describe is impossible.
I think you're mistaking what the minimum stake age does. The fact that the attacker cannot mine when sending his coins to himself has nothing to do with the fact that the chain he's building will eventually be accepted or not.
I agree that this discussion isn't going anywhere so I hope you'll take time to give some feedback on the update version.
