With news of busts of users of Monopoly Market having been revealed, it is clear that privacy and security are more important than ever.

Once completed, you'll be given a mnemonic code. Ensure you save this in case you ever forget your password). You can then proceed to login.

Quantum Marketplace features a clean and easy to navigate layout, with all they key functions you need being located within the header of the market. In this respect it's somewhat similar to many other markets out there, meaning it's easy for newcomers to navigate.

The rules are in line with most darknet markets. No sales of weapons, CP, fentanyl, poisons, terrorism activity etc. Misleading listings or duplication of listings (a common problem on some markets) is also prohited, with vendors sent a warning or banned should they break any rules.
The bond for new vendors is $500 for physical vendors, or $250 for digital vendors. Established vendors with over 500 sales can apply for a bond waiver.

In order to search for a product, you must first select a category or sub-category from the Marketplace page (listed on the left hand side). From there you can then filter by origin country, destination country and dispatch type, then sort according to price or age. This does mean there are fewer search options to choose from compared with some other markets, but it's still enough to identify what you're looking for most of the time.

Below the product photo you'll be able to see how many sales that product has had, and any review feedback left by other buyers. To view more detailed text feedback, click the 'feedback' tab above the item description.

As well as details about a specific product, you can also view more information about a specific vendor by clicking on their name (to the right of the product photo). Here you can see their vendor profile, public PGP key, how many total sales they have had, view feedback from across their entire product range, and see their average review scores. You can also send the vendor a private message or follow them so you can easily find them again in future.

Before making a Bitcoin or Monero deposit to the address provided, be sure you're not on a phishing site (check your onion link against those listed on Torhoo.com). It is advisable to deposit slightly more than the quoted cost in case there is fluctuation in the crypto price between the time you make the deposit and the time it appears in your wallet. Be sure to factor in shipping costs.
Once the deposit is confirmed, you can proceed with a purchase. Select the item you want from the relevant product page, enter your shipping option and quantity, then select 'Pay with Bitcoin' or 'Pay with Monero'. On the next screen, you can then enter your address details and proceed to complete the order.

Quantum Market rates vendors according to a system called 'electrons'. Each vendor starts with 100 electrons, and this may increase or decrease based on its activity in the market:
each shipped order (+1)
each finalized order (+1)
each dispute won (+1)
each 5 star feedback (+2)
log in every day (+10)
each canceled order by vendor (-1)
each auto-canceled order (-1)
each dispute lost (-2)
each 1 star feedback (-2)
logged in more than 3 days ago (-10/day) Fe.: logged in 5 days ago (5-3)*10 = 20 electrons will be deducted
Vendors with more electrons can be considered most trustworthy and will gain lower commission rates over time (starting at 6% and dropping to 4%).

Clean and user friendly interface
The electron system encourages and rewards vendors for good practice
Support for both Bitcoin and Monero

Fewer advanced search options than many rival markets
Feedback cannot be viewed by vendor, only by individual product Feature added!

It's clear the team behind Fish Market don't simply want to be just 'another market' and have done things their own way, with many unique and innovative features. When a platform has had some much time and attention dedicated to its development, it's generally a safe bet that the team behind it will be in it for the long haul, so don't expect to see Fish exiting any time soon. On that basis, we can certainly recommend it to vendors and buyers alike, and we very much look forward to seeing what further developments the team make in the future.
