Bisq 2 From Bisq Wiki Jump to navigation Jump to search Bisq 2 is the successor to the original Bisq ( Bisq v1 ). It has been developed from the ground up to allow for multiple trade protocols to be accessed via a single decentralized exchange platform. At the initial launch of Bisq 2 will support only one trading protocol ' Bisq Easy '. Over time more trading protocols will be added. Once the Bisq Multisig protocol is implemented in Bisq 2, the old version of Bisq can fade out. Bisq 1 will still find its usage as Bisq DAO management tool and for BSQ-BTC trading. Similar to Bisq v1, Bisq 2 will be a decentralized bitcoin exchange that allows anyone to buy and sell bitcoin in exchange for national currencies or other cryptocurrencies. Bisq 2 is a desktop application that works across platforms. Bisq 2 allows users to choose between multiple trading protocols to find the best fit for their preference. Aspects like privacy and security, convenience, costs and trade duration will differ and the user can make the choice. Bisq 2 is a peer-to-peer network the enables users to find people to trade with, make and take offers to buy and sell bitcoin, communicate with their trading peers and when necessary access support. Bisq 2 is privacy focused, no verified accounts or KYC will be required and run over the Tor network (as well as I2P in future). Bisq 2 is self custodial. Your keys are always under your control. Bisq 2 is open source (AGPL) and built and maintained by contributors who form the Bisq DAO.

Bisq v1 is a powerful tool for bitcoiners that want to be able to buy and sell bitcoin peer to peer whilst maintaining their privacy, not having to undergo arduous KYC processes, and keeping control of their bitcoin. Bisq v1 was launched on mainnet in April 2016 and whilst there has been constant improvements to the trade protocol and user interface over the years it was designed from the outset to support only one trade protocol. As bitcoin has developed and Bisq user base has grown there has been an obvious need for Bisq to expand it's offerings to offer more options to it's users for example trades over lightening and access via mobile devices. Bisq 2 is the first step to develop something that is built from the ground up to be more accessible to users and provide access to multiple trading protocols that can expend over time. The core benefits of Bisq 2 are: Multiple Trade Protocols Bisq 2 will offer a variety of trade protocols for users. Each trade protocol will come with it's own benefits and tradeoffs. Having multiple protocols allows users to choose what trade protocols are best for them based on; convenience, security, miner costs, trade fees, privacy, available support etc. All trade protocols can be accessed independently and users can switch between protocols for different trades. The follow trade protocols are on the roadmap: Bisq Easy : Reputation based trading with no security deposit requirements (included in the intitial launch) Bisq Multisig: Similar to the current trade protocol used by Bisq 1 but with some improvements Submarine Swaps: Atomic swap of LN BTC mainnet BTC Liquid Submarine Swaps: Atomic swap of LN BTC Liquid BTC Liquid Multisig: Bisq Multisig ported to Liquid network with faster confirmation, lower fees and better privacy (confidential transactions) Bisq Lightning: LN BTC Fiat (chain of multiple protocols: Liquid Submarine Swaps, Liquid Multisig) Liquid Swaps: Atomic swap of Liquid BTC Liquid assets like L-USDT BSQ Swaps: Atomic swap of BSQ BTC Monero Swaps: Cross chain atomic swap of BTC XMR Find out more about the trade protocols Bisq 2 will use. Multiple privacy networks Bisq 2 will support multiple privacy networks. Initially it will only support Tor but I2P support is already implemented but in an experimental state. Upcoming privacy networks like Nym could be added in future if they fit the requirements. Having multiple networks adds resilience in case one network has availability issues (as it happened multiple times with Tor when DoS attacks decreased the Tor network stability and with that Bisq's availability and stability). The P2P network has also a build in DoS protection using Proof of Work and come with many improvements compared the Bisq 1 P2P network. Multiple Identities Bisq 1 used a single onion address and key pair which represent the users identify. Bisq 2 will allow to create multiple identities, giving the user more control and better privacy. The user can choose between the highest level of convenience and use just one global identity for all interactions (like Bisq 1) or at the other extreme use a separate identity for any type of interaction (e.g. use a different identity for each trade as well as for each chat room). And anything in between (separating fiat and altcoin trades,...). Find out more about how Bisq 2 manages identities . Multiple applications The reference implementation will be the Bisq 2 JavaFx desktop application. But there is also ongoing work on a HTML interface with a headless application to be used on personal Node projects like Start9, Umbrel, MyNode,... Beside that there will be a REST API (useful for trading bots,...). Bisq Easy can be implemented as a mobile app (at least for Android there are no conceptual or technical hurdles). Multiple wallets At launch time Bisq 2 will not include a wallet, but work is underway to support multiple wallet options. Bitcoin core as full wallet is already implemented (but not exposed in the UI). For users who do not want to run a full Bitcoin node, there will be a light wallet option. Currently Electrum is implemented but we might change to another solution. For the different trade protocols there will be the specific wallets requires. E.g. for Liquid the Elements wallet is already integrated. For Monero Swaps we need to provide an interface for using the Monero wallet. Find out more about the Bisq 2 wallet . Bonded Roles The contributors providing the resources and infrastructure for Bisq 2 will require their roles to be bonded. This concept was also used in Bisq 1 but as it was not strictly enforced by the system, not all roles are secured by bonds as it was envisioned. In Bisq 2 having set up a BSQ bond is mandatory for most roles and node operators and enforced by the system. Find out more about the Bisq 2 roles . Bisq 1 vs Bisq 2 When Bisq 2 is launched it will initially only use the one trade protocol ' Bisq Easy ' therefore the differences are based on a 2-of-2 multisig protocol (Bisq 1) vs a reputation based trade protocol (Bisq Easy). Bisq Easy was designed for new Bitcoin users who have not yet purchased Bitcoin and thererfor cannot use Bisq 1 due the requirements of the security deposit. A lot of effort was put into making it as simple to use as possible. Bisq Easy tries to replicate the experience of a novice Bitcoiner visiting a Bitcoin meetup and getting a gentle and friendly introduction into the Bitcoin world as well has the opportunity to purchase their first Bitcoin from a helpful peer. This is inspired by the famous Satoshi Squares (early days informal Bitcoin meetups), which was also the initial name inspiration for Bitsquare - the previous brand name of Bisq. The seller is expected to be an experienced Bitcoin and Bisq user and to have built up reputation. The seller should be helpful and serve as guide through the newbies first Bitcoin trade. Bisq Easy tries to be a much more social experience as it is the case on Bisq 2. It also provides a "learn" section where newbies can learn about important topics like wallets, privacy and security. The various sections for chat rooms should also boost the social and communicative aspect of Bisq Easy. Main differences for BTC buyers Initially when Bisq 2 is launched the difference between versions will be that Bisq 2 will allow for users to buy bitcoin with no security deposit, no trade fees and no miner fees. Whereas, Bisq 1 will allow users to buy bitcoin with a security deposit and incur trade fees and miner costs. The tradeoff for Bisq 2 is that the security of the trade will be based on seller reputation as opposed to Bisq 1 where the security of the trade is based on bitcoin collateral secured in the multisig. Therefore, Bisq 2 will be cheaper and more convenient to trade for bitcoin buyers but at the cost of less robust security than Bisq 1. This is opposed to Bisq 1 that will be more secure but also more expensive, in terms of trade and miner fees, and less convenient for bitcoin buyers. Bisq 2 will initially be more suitable for users wanting to complete trades for small amounts of bitcoin, whereas, Bisq 1 will continue to be suitable for users wanting to complete trades for larger amounts of bitcoin. Main differences for BTC sellers Initially when Bisq 2 is launched the difference between versions will be that Bisq 2 will allow for users sell bitcoin with no security deposit, no trade fees and no security deposit. Whereas, Bisq 1 will allow users to sell bitcoin with a security deposit and incur trade fees and miner costs. Sellers on Bisq 2 will be expected to build their reputation . This can be done in multiple ways but to achieve a high reputation they will need to either burn BSQ and / or create a BSQ bond that locks in a specific amount of BSQ for a specified length of time. The first iteration of Bisq 2 will have more buyers than sellers. That means a small number of sellers will be servicing the buyers. Bitcoin sellers on Bisq 2 will be required to make a judgement on how best to achieve their reputation and what the cost of doing so will involve. Bitcoin seller's using Bisq 2 will also need to account for the fact that bitcoin buyers are not putting down a security deposit for their trades so there will likely be a higher trade abandonment than in Bisq 1. It is expected that some bitcoin sellers currently active on Bisq 1 may choose to experiment with Bisq 2, and the number of buyer and sellers on Bisq 2 will grow over time. As in Bisq 1 seller's will be able to choose the price above or below market they wish to sell their bitcoin for. Due the requirements on bonds and the potential higher effort on communication with a newbie Bitcoiner, the price premium can be expected to be much higher than in Bisq 1 (maybe 10-15% above market). The Seller is the one who sets the price. How Bisq 2 keeps data private Bisq 2 achieves date privacy for users in the same way as Bisq 1: Using Bisq requires no registration or centralized i
