Abstract

In the last years the Internet has deeply changed the business world and introduced many new opportunities. Every day billions of dollars are spent in on-line services and electronic 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 websites 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 existing P2P networks and well-known cryptographic methods to support secure exchanges and user reputations tracking.
