Doesn't matter; there are no technical details for this, and so far nobody has a solution on how to do this. Yes, permissionless networks exist; but no network has transitioned from a permissioned to a permissionless network. While transitioning from a permissioned to a permissionless network, you open your gates to a horde that are financially incentivized to exploit this newfound permission. How then are you going to secure yourself from an attack? Nobody has this figured out. It's mathematically unsound.

  It doesn't make any strategic sense either: The whole point of being "permissionless" is to increase initial adoption by providing protections against "vendor lock in". But if you are capable of doing an initial launch on an permissioned ledger and achieve the initial network effects anyway, what's the point of providing such guarantees later on?

  There is nothing mathematically unsound, I would even say that it should be trivial to transition to a permissionless setting. You just need to implement a proof of stake algorithm. The only questions are: what scheme do we want to implement and when does it make sense to transition. Libra launching as permissionless would be DOA.

    tell me how to transition from pow to pos
    - baby 7y ago
      why? Libra is not pow.

  Or, the regulatory obstructions and general enmity towards anything crypto would make it impossible to launch a permissionless one. Actually, several govts have been explicit that even the permissioned is ex ante banned
