50 million Lumens awarded for the second Stellar Build Challenge

2017 is off to a great start at Stellar and we are looking forward to an exciting and productive year ahead!

For the first Stellar Build Challenge of 2017 we created a total prize pool of 118 million Lumens to be awarded to top submissions across multiple categories. Entries were judged by a panel of experts from the Stellar community who reviewed each submission for solid craftsmanship and innovation in the Stellar ecosystem. Our esteemed panel of judges reviewed 47 submissions and awarded 50 million Lumens for their favorite projects. With 68 million Lumens left on the table, we hope you’ll find millions of reasons to participate in the next challenge!

The first Build Challenge of 2017 built on the success of our pilot back in October and the results again exceeded our expectations. Below you will find a list of all the entries that met the criteria, with the entries that received the highest marks and Lumen winnings in their category listed first.
