OpenBazaar is a new way to trade online. By running a program on your computer, you can connect directly to other users in the OpenBazaar network and trade with them. This network isn't controlled by a company, it's a decentralized network that isn't run by any organization at all. This means there are no mandatory fees to pay, and that your trade is censorship-resistant.
OpenBazaar uses Bitcoin, a digital currency that is also cheap to use, decentralized, and censorship-resistant.
This project is open source, which means the code is publicly available, can be reviewed, and anyone can join the project and suggest changes.
