Hi AEternity Team!

In your whitepaper you state that you changed your mind about 100% PoS blockchain, although it was in your plans initially. I wasn't able to find explanation about your reasoning on the matter. Can you please elaborate on this ? It seems Vitalik still believes in PoS and there are already some attempts to launch 100% PoS blockhains. Why do you think that a "decentralized 100% PoS" is impossible ?

Best Regards!
