Name some other deployable payer anonymous electronic payment systems that are in competetion with DigiCash.
Stefan Brands patents? Not sure if digicash would claim these infringe the blind sig patents. Ian Goldberg's HINDE/money changer with or without blinding -- in general notion that you can obtain anonymity by anonymous exchange from a trusted money changer, or with blinding from an untrusted money changer. As with remailers you can increase the strength of anonymity by chaining through multiple money changers. Or perhaps Doug Barne's proposal for a identity agnositic bank and blinding clients distributed from jurisdictions where doesn't have patents? (The client is the software which does the blinding). Pseudonymous approach to anonymity -- ecash accounts without an TrueName indentity bound to them. Others? (Ryan you suggested 5 but didn't list them explicitly?) Adam
