Proof-of-stake is a consensus mechanism that is usually use to process all types of transactions and also create new blocks inside a blockchain.

I love the way you gave your reasons why proof-of-stake consensus mechanism is important to the Blockchain

Yes, the blockchain can exist without the concept of Proof of Stake.

You are perfectly right with this statement mom. Yes the only reason now will be the problem of transparency immutableness within the Blockchain because the data stored inside won't be trusted any longer since it can still be edited and change. But with the use of POS, this can't happen and hence the data will fully be trusted
