It's similar to Bitcoin, which has no central control, but now has an ecosystem of businesses that support Bitcoin users.
Our goal with OB1 is to build the OpenBazaar network and gain large adoption, and then offer those users services (such as dispute resolution, store hosting, search).
Help me OB1, you're my only hope.
For example, Andreessen Horowitz has invested quite a lot of money into Bitcoin mining operation, 21 Inc, who in turn have mined a lot of Bitcoin. If Bitcoin's price goes up, the value of 21 Inc's holdings go up.
BitTorrent received $41M in VC funding, and is free, does not collect data, and is not centrally controlled. They monetize through content distribution software integrations, business software, a search engine, and an ad supported Torrent client. I imagine OpenBazaar will monetize in similar ways.
Note: >to develop the OpenBazaar protocol and client, _and build the first business on top of the OpenBazaar network._
I think that the can be only One marketplace since it relies heavily on the network effect. For OB to be first and biggest is a big deal.
These are Open Source, but you can pay them to host for you.
