Community points are different. They are only used within a community, mainly in crypto communities.

The idea is that instead or in addition to worthless upvotes, you can send users a sort of tip for their comments and posts. The tip is a digital coin, and the recipient can give it to other users or sell it for real money (presumably to another user who will use it to give someone a tip).

Obviously if real money is involved then blockchain is preferable to trusting reddit admins. And the idea isn’t totally stupid, IIRC there is/was a similar internet currency that you could use to “buy a coffee” for your favorite content creators in the pre-Patreon days. But I have no idea if the reddit version is implemented sensibly.
