What are Decentralized Markets? • Coin Center

Decentralized markets are an emerging technology which give people the ability to participate in online commerce that is completely different from the traditional centralized model. Instead of having a company with a website offer a central meeting place for buyers and sellers, decentralized markets work by having buyers and sellers connect directly to each other. This is accomplished by running a peer-to-peer program on their computer, and using digital currencies such as Bitcoin for payment.
