Re: Chaum's patent on traceable payment systems

Chaum's "limited-traceability" patent includes other features which directly counterbalance those of the Abstract accurately posted by Anonymous. We've transcribed the initial sections of the 17-page patent which provide a fuller view of what his system offers: http://jya.com/chaum-lts.htm It's an interesting, nuanced proposal, from 1994, which helps explain some of the strategy he's been keeping close to his chest until patent approval, and which may portend more provocative designs in the pipeline for outfoxing the keepers of the chickens.
