For example; Picking one article up (https://steemit.com/piston/@xeroc/piston-web-first-open-source-steem-gui---searching-for-alpha-testers) may I know what are this "Pending Payout $ 21,362.86" mentioned below the article imply?
Also how is this technology supposed to liquidate its assets in future?
That is total reward that is scheduled to be paid (assuming votes aren't changed, the market value doesn't change, other posts don't pull more or less from the reward pool, etc.) to both the author of the post as well as voters on the post. Most of it goes to the author.
I don't understand the question about liquidating assets.
