Posts and comments on the main page cost 1 sat. Tips (aka upvotes) cost at least 1 sat, but the current default is 10 sats per bolt click.
When people tip your posts and comments, those sats go to you. Users who have created valuable content are also given sats daily. These sats come from ~jobs, posting/commenting fees, and boost.
The basic algorithm divides the number of users who have tipped a story by a power of the time since a story was submitted plus the boost divided by a larger power (relative to un-boosted ranking) of the time since a story was submitted. Comments in threads are ranked the same way. Each user's tips are weighted by how much a user is trusted.
Tips (denominated in sats) go the user that posted the story or comment being tipped. Each user can tip a story or comment unlimited times.
Boost allows users to boost the ranking of a post upon creation.
If you press and hold the tip button, a dialog pops up to tip a custom amount. Optionally you can set a higher default tip amount by visiting your settings.
