> Wouldn't such an exchange be a good use case for a smart contract? There were several such "decentralized" projects (Augur, etc.), but I don't know of anyone who uses them. I kind of stopped following the "permissionless" space after several projects turned out to be too scammy for my liking. > It probably also would do away with the KYC, so everybody could participate. Nobody would have to give away their private data. That's exactly why they're not allowed. If you can't easily get fiat in and out of such contracts, they can hardly matter. Kalshi: not a novel idea, but it's good to see another implementation. Several solid blockchain projects (also permissioned/KYC, but based on blockchain, with distributed oracles) are launching similar markets in 2023. I think they will have an advantage because all participating financial institutions will be able to create own markets without reinventing the wheel or building their own in terms of underlying infrastructure (APIs, smart contracts, etc.). Some already have simple apps (decentralized price feeds, etc.) in beta now - they just need to add the ability to bet on outcomes. I don't want to "advertise" their names here but you can look them up on the Internet.
