 [appendix]
 == Appendix: Bitcoin financial services

 This appendix describes the main financial services offered in the bitcoin economy, comparing them to traditional financial services that are already familiar to consumers. It's not a list of sites or companies, as that would go stale immediately. Instead it is a list of service primitives with examples of existing implementations. For example, an escrow 
 service would be described as an archetype, by analogy to a real-estate escrow, showing the unique characteristics, use case and need for escrow in the bitcoin world. The escrow service archetype would be followed by two or three examples of well implemented actual escrow services, each demonstrating a capability unique to bitcoin.
