Jocasa
Jocasa is a real-time analytics and quant platform on Robinhood Chain. I started building it on Sept 25, 2026. The status page below shows where it stands.
The chain reader is live. Jocasa picks up every Robinhood Chain transaction straight from the chain's live feed, about a second after it happens. It runs on its own servers, checks each signature, decodes each transaction and keeps what it needs in Postgres. It's also pulling the chain's history into its own archive, and that job is paused while I fix it.
The analysis on top of that is partly live. So far it can tell real buys and sells apart from transfers and liquidity moves. The order engine runs only on a simulated chain, where it passes its tests, and no real orders go out.
Status page
This is the whole page, as the person I'm building Jocasa for sees it. It updates itself from the running system every two hours.
