Abstract:
A credit network models trust between agents in a distributed environment and enables payments between arbitrary pairs of agents. With their flexible design and robustness against intrusion, credit networks form the basis of several Sybil-tolerant social networks, spam-resistant communication protocols, and payment systems.
In this talk, I will introduce the concept of credit network and characterize the privacy issues in currently deployed credit networks such as Ripple. I will also overview some of our privacy preserving payment systems that offer a tradeoff between security, privacy and compatibility guarantees for credit networks in order to meet the specific requirements of different applications.
