The document describes a system called CoinZ Digital Currency that is used to handle all work through a content protection system. It outlines a process where a buyer (Bob) would post a job offer and negotiate a price privately with a seller. Bob would pay half of the agreed price up front in CoinZ digital currency. The seller would then provide half of the content, which Bob could view and approve. Upon sending the remaining payment, Bob would receive a key to unlock and view the full content. The system aims to protect both parties and ensure payment is received before full access to content.
