I just read about it. It seems highly susceptible to disruption by a minority stake, via the birthday paradox.

If only a fraction of the stake holders are validators at any given time, but the set of 1000 validators is selected randomly from token holders, then all you technically need is 1000 tokens (or more) and given enough time you will be selected as the only validator, right? You can then validate a fraudulent transaction, breaking security.

Now perhaps the amount of time it would take for this to occur would be longer than the heat death of the universe if you only have 1000 tokens, but at the very least, this substantially reduces the stake required to mount such an attack below the 51% required in a PoW system, right?

thats why currently the minimum stake amount is 32 eth. Also, you'd learn you were the validator for the cycle only when you are awarded eth. If you try to push through a false transaction you can get slashed (Losing some of your stake). all in all, makes it impractical at best.
