Careful optimism was the theme at this year's Paris Blockchain Week. Builders will build and the crypto community will keep going. Expectations for Paris Blockchain Week were relatively low considering the downbeat market conditions. However, Paris can always surprise you. Indeed, conference halls at the event were not nearly as empty or depressing as Consensus after the big crypto meltdown of 2018. People were present, and conversations were fruitful. (And yes, the croissants were, as always, delicious.)
