Decentralized online shopping. This is like ebay, but there are ZERO listing fees and NO ONE in charge. You sell what you want, how you want, for how much you want. It's not a website. It's a peer to peer garage sale with a slick front end. It is FULLY decentralized. As always, shop at your own risk and expense. Regarding risk, you can add moderators as 3rd party judges to protect your customers and give them confidence when they buy from you.
Open Bazaar will work without centralized DNS.
It will work without central servers.
User accounts are self-hosted, meaning the user is in full control. Monetization is uncensorable and unstoppable with cryptocurrencies.
