Secure Digital Gift Cards on Bitcoin
Giftblock is a protocol for gift card and stored value card on the Bitcoin block chain. It is built as a set of extensions on top of the Open Assets Protocol:
- Store Card Asset Definition File Extensions
- Payment Requests specification: extensions to BIP-70 and BIP-21 describing payments in terms of assets instead of (or together with) regular bitcoins. See Open Assets Protocol
- Payment Methods specification: A protocol for negotiating the assets to be included in an Open Assets Payment Request. See Open Assets Protocol
