Today we talked about working with history (again!) but this time with a more detailed lens, and @arichiardi gave us a tour of some tricks that the team at Cohesic have figured out and released as a library (also mentioned here). There was even some discussion about state machines, featuring GitHub - metosin/tilakone: Minimalistic finite state machine (FSM) in Clojure 
You can register for next week’s meetup event here - I’m planning to walk through various transaction function examples at the Clojure REPL.
If anyone would be interested to similarly share something you’ve built with XT, you would be most welcome 
Until next time!
