What's really interesting to me is that all these advancements could have been made by a centralized service for stock trading as well if the debt based system and T+3 days margin calls wouldn't be a requirement. DTCC owns most US stocks, so I don't see why they wouldn't be able to launch uniswap style contracts to allow better use of liquidity instead of just having simple limit order contracts.

>What's really interesting to me is that all these advancements could have been made by a centralized service for stock trading as well uhh, what? The two features that were introduced were "Concentrated liquidity" and "Multiple fee tiers". I'm not sure how either of them are applicable to centralized exchanges. >and T+3 days margin calls wouldn't be a requirement. https://news.ycombinator.com/item?id=26007414 https://news.ycombinator.com/item?id=26007414

  Concentrated liquidity is needed because of the huge cash requirement right now (as the link that you provide writes about it). Having guaranteed execution with real time clearing, real cash and smarter contracts is a sounder system than stupid contracts and margin trading with slow clearing.

Is anyone building this for the traditional finance system, with actual shares as collateral? I know of Mirror Protocol & FTX, but they are just p2p swaps/futures. My email is in my profile if anyone wants to discuss further.

  Good luck, it would be great! It was interesting seeing WeBull's CEO talk about how bad is DTCC for them, and how strong monopoly it has, but still he wasn't doing anything about it. The opportunity is huge, but I guess that means that the execution is very hard.
