Tigerbeetle is a fault tolerant database that’s used for finances and time series stuff. It’s a field that has very particular requirements around this sort of thing.

(not a tiger beetle user so I’d love to also see some more context for this)

Looks nice, but... what is this and how is it supposed to work?! There is no explanation, no tutorial, ...

Joran from TigerBeetle here!

This is a “walking sim” real visualization of our Deterministic Simulation Testing harness, the VOPR.

Typically we do DST headless in the terminal but this is a visualization, more or less the same thing but with a gaming engine on top.

It’s running real TigerBeetle code, but with simulated network/storage and fault injection, and multiple replicas in a cluster, all compiled to WASM and running in the browser, and you can interact with the simulation to poke it and watch the consensus recover.

Here’s the full background context and explanation from our talk, TigerStyle, for which we developed this sim: https://youtu.be/w3WYdYyjek4
