HackCanton S3 is a wrap, and Umbra made the Grand Final! Some notes on what building a dark OTC venue on @CantonNetwork taught us this season; Like I've always said, @UmbraOnCanton is a private RFQ venue for block trades, where each quotes are visible only to the parties who need to see them, thanks to Canton’s sub-transaction privacy, so basically, when a trade is agreed, both legs settle atomically as a CIP-56 DvP. Nobody has to trust anybody’s books. This season 3, we actually focused more on decentralization. We co-hosted parties with @BitSafe_Finance's node, then stopped our own node and settled a trade on DevNet anyway. Seeing that update id land was the moment it clicked, that the venue no longer depends on us staying online. One thing we learnt with multihosting tho, is that it's powerful, and truly useful, but you have to design for it from day one, to save you lot of stress. To be very honest, the bar this season was seriously high. Finalists built things that only make sense on Canton, and i actually learnt a lot from reading them! Congrats to every finalist and every team that shipped🫡 And a huge thanks to @appsfactory_cc and the judges🫡
