What We’re Reading, Watching, and Attending!
We’ve been at Hyperledger Global Forum this week and today is the last day. Come attend our interactive session comparing UTXO and Account models, we’ll be giving away t-shirts to people who participate so make sure to bring your questions and thoughts.
Luís Marado and others will be showing off a large variety of Daml-based usecases (+ a few written in other languages) in Portugal later this month. Link is to come and will be shared on our social media so keep a lookout.
György Balázsi walks us through integrating Daml with Auth0’s new Actions platform for easy authentication of parties in your Daml application.
Stephen shows us the relationship between Templates and Records and how we can leverage the records in our templates to avoid duplication, create more easily understandable workflows, and other neat tidbits that you’ll just have to read the tutorial to find out.
As always RPS has a ton of security and privacy news that he shares weekly on our forum so check them out. You can even subscribe to the tag to make sure you don’t miss them.
