- littlestymaar 6y agoThat's the coolest thing about Taler: there is a thing called “the refresh protocol”[1] which allows you to obtain change after a transaction: that is, for instance you pay with a $7 token for your $5 transaction, and you get a $2 change token! [1]: section “4.7.4. Refreshing and Linking” in this paper https://ged.univ-rennes1.fr/nuxeo/site/esupversions/41aac1ac-3074-4b0e-9087-cee5f58ce0b2?inline https://ged.univ-rennes1.fr/nuxeo/site/esupversions/41aac1ac...
- runeks 6y agoThat is pretty cool! So, basically, if a merchant requests payment of $5 and the buyer only has a $4 and a $3 token then the buyer exchanges her $3 token for three $1 tokens with the exchange (without involvement of the merchant) and then pay the merchant with a $4 and a $1 token?
