Don't take downvotes so personally, they're more about weeding out bad ideas from good ones than a reflection of your worth to the community, this isn't reddit where we care about karma count. If you fix up your comment instead of complaining you might see those downvotes get reversed (I've had that a number of times).
But if you're going to use blockchains for voting, you might as well use them for the whole thing. Every new comment, every edit, every deletion and vote. Consensus as moderation.
No clue where the VR came from.
The problem with visible watermarks is it detracts from the image visibility. Nobody wants to look at photos or digital art pieces with huge ugly watermarks on them. Could blockchain tech help establish ownership in a way that would make watermarking obsolete?
edit: cool - downvotes for asking a question. Real nice guys.
