Anyone out there with a coding.clue wanna poke inside this thing and see if it's an actual bearer certificate -- and not yet another book-entry -- transaction system?
Sorry to get your hopes up ... Just reading the words below not the code: it is basically modelled on the SOX/Ricardo concepts, AFAICS. As you know, the SOX concept used (PGP) keys to make an account with the server/issuer Ivan, or a long term persistent relationship, call them Alice and Bob. DigiCash also had something like this too, it's essential for application robustness. The simplest payments metaphor then is a signed instruction to transfer from Alice to Bob, which Ivan follows by issuing a signed receipt. What you'd call double entry, but in Ricardo is distinct enough to deserve the monika triple-entry (not triple-signed, that is something different, another possible innovation). Then, the blinding formula/transaction is simply a replacement for the standard payments tranaction above: Alice withdraws a coin from Ivan, sends it to Bob, who deposits it with Ivan. (Ricardo had Wagner too from around 2001, and like this author, had a path to add Chaum, with future extension to Brands. The code for Chaum was mostly written, but wasn't factored correctly...) Another possible clue: the author has obviously taken on board the lessons of the Ricardian Contract form, and put that in there (albeit in XML). I find that very encouraging, even the guys from DigiCash never understood that one! So I'm guessing that they have studied their stuff. BTW, FTR, I do not know who this is.
Cheers, RAH Who sees lucre down there in the mousetype and takes heart...
Lucre was 1-2k lines. Ones heart beats blood into thin air until there is another 1-2 orders of body parts built on... This is looking much more like that 1-2 orders of magnitude down the track. iang
