Open Developer Streams are a unique way to fund development and give developers at the edges the freedom to build what they think is most important.
Their smart contracts get replenished monthly and allows them to withdraw funds whenever they like by submitting a few sentences about the work or a PR.
This approach produces novel open source solutions and a vibrant learning environment.

Focused Cohort Streams bundle together a group of developer streams and focuses them on a pre-determined objective.
These cohorts provided the structure and guidance of an Operator who identifies, adds, and removes developers from the pool.
