The Woz and Molly Bloom spoke at the cryptocurrency convention, ChainXChange, at the Mandalay Bay in Las Vegas, but had a meeting of the poker minds backstage before going onstage.

If you're unfamiliar with Molly ... she's a badass. Molly's the inspiration for Aaron Sorkin's first film as a director. He also wrote the script to the flick starring Jessica Chastain as Molly.

Molly ran a high-stakes poker game back in the day at the famed Viper Room in L.A. ... frequented by celebs like Ben Affleck, Tobey Maguire and Leonardo DiCaprio ... and the freakin' Russian mob.

See, badass.

We're told the meeting between Wozzy -- an avid poker player -- and Molly played out more like a mutual admiration society. And, for the record ... no real money changed hands ... it was all in fun.
