The specification is now reasonably complete enough that we would like to receive input from the community. The PDF is available for viewing here: http://freico.in/docs/freimarkets-v0.0.1.pdf We're looking for public comments about this or related approaches. In particular we've spent a fair chunk of time working out how to handle coordination of private accounting servers with the public chain and derivatives contracts, both of which are basically cryptographic protocols expressed as bitcoin scripts. Input from any of the resident cryptographers would be very appreciated.
