Abstract

In the last years the Internet has deeply changed the busi- ness world and introduced many new opportunities. Every day billions of dollars are spent in on-line services and elec- tronic transactions among users all over the world. Travel agencies, on-line shops and on-line banking are probably the most popular services nowadays, together with auction web- sites like Amazon or eBay. Unfortunately, maintaining such services with a centralized architecture is very difficult and expensive. In this paper we introduce a possible architecture for a decentralized marketplace like eBay, that uses an ex- isting P2P networks and well-known cryptographic methods to support secure exchanges and user reputations tracking.
