i have discovered a flaw with current PoS implementation
you can easily do a 51% attack with PoS blocks without needing large holdings
since PoS blocks are generated on a coin age basis, you could create TXO's delayed by a time offset at the minimum TXO cost for a future attack period
so after creating 10000 TXO of 1 MINT separated by 0.5 seconds to make sure 60 consecutive blocks are generated at repeated interval by your wallet 20 days in the future, the attack would last 1 hour and 40 minutes
enough to put the security and function of a coin in question
couple that with the fact the difficulty calculation includes PoS blocks, that would mean difficulty would jump to stratospheric levels making it impossible to mine PoW blocks
