> The ongoing coin-days staked in that fork specifically is what allows it to continue making forward progress. Coin-days staked has no bearing on a pure PoS chain’s risk of being 51% attacked, nor does it have any bearing on the risk 1/3 or more of its validators get disrupted. Not so with PoW hashrate: enormous hashrate imbalances between forked PoW chains directly translate into decreased data immutability per the risk of deep chain reorgs. Those risks are simply not present in the PoS corollary.
