It is a permissioned Blockchain this is Vitaliks critique
Dan's EOS achieves its high scalability by relying on a small number of what are essentially master nodes of a consortium chain, removing Merkle proofs and any other protections that would allow regular users to audit any part of the system's execution unless they want to personally run a full node themselves. See http://vitalik.ca/general/2017/05/08/coordination_problems.html for why I think this is undesirable.
Du meinst weil die Witnesses im Rundverfahren arbeiten und an den LIB ansetzen ist es kein 2Phasen Quorum? Warum skaliert es dann nicht in der Anzahl der Validatoren. Werde es auch nochmal durchlesen. Super Einwand
