The site however does use the Lightning Network to provide Sybil resistance. Upvotes/posts/comments cost 1 sat, ~1/2000 of a dollar. This helps gate the site allowing mostly Bitcoiners in and imports an incentive structure - those more like in person social interactions.

Rather than staking your reputation, you're staking Bitcoin. Rather than earning just reputation, you're earning Bitcoin (your earned karma/upvotes is Bitcoin you can withdrawal from SN at anytime).
