Oh I remember when they switched to V2. Is there any details that you can share? Why you feel impressed, how it effected your user experience?

V3 has been out for a couple years now.
I've just been learning the details in the last few months.
There is lots of impressive stuff, spanning the capital efficiency improvements, the P&L behaviour of the liquidation positions...all supported by this tick-price convention and data structure that allows price to clear but also balance with quantities as price change.
