How does time work in a POS system? In POW, the block time is a result of the difficulty, which relies on very low accuracy time-stamps for blocks. Yet, with POS it seems to me I can 'mine' a block at any given moment. Thus, what determines the 'block time' in POS? If the 'block time' gets to be too fast, then the size of the blockchain is going to be quite large.
