Bisq is a cross-platform desktop application that allows users to trade Bitcoin for national currencies (USD, EUR, etc.) without relying on centralized exchanges like Coinbase, Bitstamp or (former) Mt.Gox.

Users form a peer-to-peer network by running Bisq on their local machines. Trades to buy and sell Bitcoin are broadcast to this network and facilitate the process of those trades via the Bisq UI, and thus, a Bitcoin marketplace is established.

There is no central point of control or failure in the Bisq network. There are no trusted third parties. Bitcoin to be bought or sold is held in escrow using Bitcoin protocols native multi-signature transaction functionality when both parties agree to exchange Bitcoin for national currency.

As the trade of any national currency must be transferred through traditional means, such as wiring money, Bisq introduces support for human arbitration to settle mistakes or disputes.
