Let's make trade free.

OpenBazaar is a decentralized peer-to-peer marketplace where goods and services are traded in Bitcoin. OpenBazaar uses a Kademlia-style distributed hash table (DHT), which is architecturally comparable to BitTorrent. Items are created and hosted on the nodes of users on the network. The project is originally based off of the proof of concept code for DarkMarket, created by Amir Taaki and Airbitz, and is now licensed under the MIT license.


You can financially support the project by either:

  1. A direct donation: 3MXYUBLWNETa5HTewZp1xMTt7AW9kbFNqs
  2. Tip4Commit:
    • Code committed to the project is rewarded with bitcoin: tip for next commit

Features (Notional)

  • Full market editor for management of items catalog
  • Order management system
  • Ricardian contracts
  • Multisignature escrow-based transactions
  • Notary and dispute resolution marketplace
  • Private messaging
  • Identity/Reputation system

Project Status

  • OpenBazaar is currently in Beta 5.0
  • New versions are scheduled for release at the end of each month
  • Development Roadmap

Build Instructions

For Linux and OSX users, run these commands:

git clone

cd OpenBazaar


After running the script you should have an OpenBazaar installation ready to go, to start run:

./openbazaar start

OpenBazaar will open in a random port on your default web browser. Note that it may take several minutes for OpenBazaar to completely start.
