Re: Proof-of-stake can never scale without blowing up, because PoS isn't trustless
Can PoS coins Hard Fork , Answer is Yes
Can PoW coins Hard Fork, Answer is still Yes.
Can PoW coins Hard Fork, Answer is still Yes.
I will address this because it is technical claim.
It is very difficult to hard fork a PoW coin, as evident by Bitcoin's block chain debate, the fact that Bitcoin was never forked (only a bug was fixed to make it agree with the protocol as specified), and also that Ethereum had to revert to voting by stake to take a vote to try to push the miners to support a fork.
Whereas, PoS coins have been forked by an exchange (as quoted from Vericon's white paper in the OP), something that could never happen to PoW coin with any decent amount of hashrate.
That PoS coins aren't forked is because of adhoc social contract that records checkpoints and thus has centralized the coin.
Besides I have another design for PoW which will make it virtually impossible to fork the coin, because the miners will number in the millions.
It is no more difficult to fork a PoW than a PoS, all depends on if the users upgrade or not.
Still not seeing any valid points here.
FYI:
Until you actually get a coin working, keep the vaporware comments out of the conversation.
