Steem "bluepaper" to the masses: Decentralized Exchange.

Content excerpt from this original pdf version of the "steem-bluepaper"
_{Steemit, Inc., 2017}

The Steem blockchain offers a decentralized token exchange, similar to the Bitshares exchange. The exchange allows users to trade their STEEM and SBD tokens through a public decentralized peer-to-peer market. Users are able to place buy and sell orders, and order matching is performed automatically by the blockchain. There is also a publicly accessible order book and order history which users can use to analyze the market. Users can interact with the exchange directly using the blockchain API, or use a GUI such as the one on Steemit.com.
