Zcash Developers Update 6-5-2020

I want to recognize the events of the past few weeks in the United States and around the world. Crucially, it’s important to recognize that Black lives matter. These protests underscore the need for change, the need for new equitable power structures, and the need for technology that protects human rights and dignity. In times of historic change and global crisis, we believe it is more important than ever to empower people and build an alternative system, which is what our work has always stood for.

Here are the updates from this week:

  • Kevin Owocki wrote a guest blog post on ECC discussing the upside of Quadratic Funding for Zcash.
  • Zcash Foundation welcomed two new team members – Jane and Teor. Congrats to ZF and welcome Jane and Teor!
