 2 | Exchanges are central to the growth of Bitcoin. 
 3 | 
 4 | An exchange can be broken into two parts.
 5 | 
 6 |  * The collection and distribution of bid/ask offers
 7 | 
 8 |  * Escrow service 
 9 | 
10 | There are advantages to breaking up this functionality into seperate
11 | services because they have very different properties. This project focuses
12 | on the bid/ask offer database. See https://github.com/donpdonp/smallest-escrow
13 | for an escrow service.
14 | 
15 | A traditional exchange with a central offers database allows for consistency
16 | at the cost of a single point of failure and a communication bottleneck. An
17 | alternative is a distributed database of offers. A participant with a history
18 | of valuable offers would be a very popular network participant and traffic would 
19 | increase at their location. It eliminates the arms-race of getting closer (network-wise)
20 | to the centralized exchange at the expense of network delay.
