Conventional wiki designs (such as Wikipedia) have a flaw; when you edit a page, you are editing the "official" version -- the last edit wins. There is no review or workflow process that can catch vandalism before it is published. In the case of Wikipedia, for instance, this leads to erroneous information being published in the encyclopedia for a short period of time, and disputes after the fact as the content is cleaned up (follow the "discussion" and "history" links at the top of any Wikipedia page to see examples of this.)

A WikiMarket works the same way as any other wiki in terms of ease of editing, but has the added tool of using weighted voting (market prices) to select the current "official" version of a page. In a WikiMarket, any edits you make are not published until the version you created rises in price to become the highest-priced version of the page; the market as a whole must concur that your edits were valid before they become "official". Most of the disputes that occur today in Wikipedia would be worked out before the new version is published, by market pricing activity.

The Trac marketplugin was the world's first implementation of a wiki market.
