Bisq

Bisq is a decentralized, open-source desktop application that enables users to buy and sell Bitcoin in exchange for national fiat currencies or alternative cryptocurrencies. It operates on a peer-to-peer network, allowing direct trades between users without relying on centralized intermediaries or requiring registration. Bisq emphasizes privacy and censorship resistance by routing traffic over Tor and using multisignature escrow deposits to secure trades. The platform supports multiple operating systems including Windows, macOS, and various Linux distributions.

Bisq offers two main software versions: Bisq 1, the original platform launched in 2016, which uses a multisig deposit system to secure trades and supports larger trade sizes; and Bisq 2, introduced in 2024, which includes the Bisq Easy protocol. Bisq Easy simplifies the trading process by removing deposit requirements and trading fees, relying instead on seller reputation for security. This makes it more accessible for smaller trades up to approximately $600 USD, targeting new users or those making smaller fiat trades.

The platform is designed for users who prioritize privacy, security, and decentralization in cryptocurrency trading. It requires users to run the desktop software locally, connecting to the Bisq peer-to-peer network. Trades are secured through a combination of multisignature escrow and reputation systems, reducing counterparty risk. Bisq's open-source nature allows developers and contributors to audit, improve, and extend the software. Getting started involves downloading the appropriate client for your OS, setting up a Bitcoin wallet, and following the guided trade process. Comprehensive documentation and community support are available through the Bisq Wiki and forums.
