Yes ofc.
It is even possible to burn coins.


Casper suggests that. Stakers could be rewarded just by fees, and some of those fees even be burned, reducing the total supply over time. This is suggested by vitalik.

Because of the lack of high electricity consumption, there is not as much need to issue as many new coins in order to motivate participants to keep participating in the network. It may theoretically even be possible to have negative net issuance, where a portion of transaction fees is "burned" and so the supply goes down over time.

Recent example XLM was burned around 50% of its supply.

the two of them are completely different.
the XLM burn was a one time thing when the owners of this centralized coin decide to burn a portion of the supply that they owned. so they did that 1 time thing.
what bitmover posted is a constant burn on each transaction, that is when you make a transaction and pay a fee a portion of it is burnt for good on that tx.
