Categories

You can win in up to two categories with a single entry.

Most Fun Application: Puzzles, Games, & General Fun

Brought to you by Union Square Ventures Analyst, Dani Grant will be looking for the most fun app. While games and puzzles are two potential focuses, any app that aims to provide end users with a fun, engaging experience is fair game.

Best Use of Twilio in a Can’t Be Evil Application

The top app in this category will be determined by Founder of New Internet Labs, Larry Salibra. Larry will choose the app that uses any of Twilio’s APIs in the most protocol-like way, while still maintaining the promise of Can’t Be Evil with user owned identity and data. Participants should think about how to turn a Twilio service into a trusted network protocol.

Best Designed Lightning Enabled Application

Judged by Jeff Domke, Head of Product at Blockstack PBC, this award will go to the application with the most polished design that makes use of both Blockstack and the Lightning Network in a core way.
