Bisq is always looking for highly-skilled developers, designers and security experts to join community. If you’re interested in helping make Bisq better, there are many ways to contribute. We’d love to hear from you! The roadmap provides an overview of high-level features and milestones on the way to Bisq v1.0.
Bisq trading fiat currency for bitcoin, there is always some chargeback risk, as fiat transactions can technically be reversed. To mitigate this risk, Bisq only supports payment methods which are known to make chargebacks difficult—this is why Bisq does not support PayPal and credit cards, for example.
To discourage fraud in fiat transactions, Bisq imposes limits on trade amounts. These limits are derived from the payment method’s chargeback risk and the age of the account (i.e., the time since you entered the payment account in Bisq).
|Number of currencies handled||Over 20 types|
|Trade Limit||0.5 BTC|
Bisq is an open-source, peer-to-peer application that allows you to buy and sell cryptocurrencies in exchange for national currencies. No registration required.
Currently no other project fits our definition of a decentralized bitcoin-to-fiat exchange. OpenBazaar is one project that comes close to mirroring Bisq’s principles, but it’s a general-purpose marketplace, not a specialized currency exchange.
Most exchanges claiming to be decentralized either do not support fiat exchange, or operate with a client-server architecture and do not fit our definition. And of course there are a lot of ICO projects with whitepapers but they have not proven yet that they can deliver any working software.
To be properly decentralized, one must avoid single points of failure:
- Bisq does not hold any bitcoins. All are held in multisignature addresses rather than a Bisq-controlled wallet.
- Bisq does not hold any national currency. National currency is transferred directly from one trader to the other.
- Bisq uses a peer-to-peer network over Tor. This means there are no servers to be hacked or DDoS’d.
- Bisq does not know traders. No data is stored on who trades with whom.
- Bisq does not require registration. This means privacy is maintained, there are no “approval” wait times, and identity theft is impossible.
- Bisq is not a company. It is an open-source project organized as a Decentralized Autonomous Organization (DAO).
To discourage fraud in fiat transactions, Bisq imposes limits on trade amounts. These limits are derived from the payment method’s chargeback risk and the age of the account (i.e., the time since you entered the payment account in Bisq). There are no limits on the number of trades you can do—just the amount per trade.
For most bank-based payment methods like SEPA or Zelle the trade limit is 0.5 BTC per trade. For services like Swish, PerfectMoney and AliPay it is 1 BTC. For recently-added payment methods like Revolut, Popmoney, and MoneyBeam (N26) the trade limit is 0.25 BTC.
Security deposits create incentives for both buyer and seller to follow the rules of Bisq’s trading protocol. They are locked into multisig escrow along with the bitcoin being traded, and are returned to each user when the trade completes successfully.
Satoshi Nakamoto created Bitcoin to solve the problems of centralized payment systems, so it seems inconsistent for centralized Bitcoin exchanges to be the primary way to acquire bitcoin. It often seems the dominance and vulnerability of centralized exchanges is the Achilles heel in the current Bitcoin ecosystem. There is much talk about decentralization in the Bitcoin space, and various attempts at creating decentralized exchanges to address this weakness.
Bisq is built for those who:
- Want to exchange a national currency such as dollars, euros, or yen for bitcoin.
- Want to exchange a wide range of alternative crypto currencies for bitcoin.
- Do not want to trust any exchange for holding their funds.
- Do not want to forfeit control or privacy to a central authority in order to trade with other individuals.
- Regard financial transactions as a form of private speech that should be protected from surveillance by banks, governments, and other institutions.
Bisq Dao Work
The primary purposes of the Bisq DAO are financing the project and determining strategy.
- Trading fees are distributed directly from traders to contributors with a token (colored bitcoin) called BSQ.
- Strategy is determined collectively through voting done in the Bisq software and recorded on the Bitcoin network.
