Yes, that&#x27;s true - it was a loosely categorized collection of my thoughts while going through the frontend. The frontend architecture is very similar to that of BitMEX, the exchange that I built, so I am very interested in the choices they&#x27;ve made, why they chose them, and what&#x27;s different.<p>Gemini is a spot exchange (simple buy&#x2F;sell) while we&#x27;re a derivatives exchange with much more complex requirements, so you&#x27;d expect a different set of decisions and tradeoffs, which is what I found. Gemini&#x27;s real value (at this point) is in its ability to navigate regulatory capture, not necessarily in its technology. But their technology is a cut above what you usually see in Bitcoin exchanges. The exchange landscape has been plagued with unreliable&#x2F;buggy exchanges, like the late Mt.Gox and the still-limping Bitfinex (which is much more complex).<p>On the whole, basic spot exchanges without leverage are relatively easy to create. I would love to do a more complete analysis but of course I don&#x27;t have any inside information. I would be very interested in their backend, which appears to (possibly) be Scala. No clues as to whether they&#x27;re using a SQL database or something more specialized like KDB+, which we use and love.
