Testnet Goals

The goals listed below are a simplified representation of our main objectives for the Sumer testnet.


Enable content publishing from playback interface

Sumer introduces the ability to create and manage channels and videos in the Joystream Player, replacing the cumbersome and technically challenging CLI-dependent process required on the Antioch testnet.


Deploying the new content directory

As part of Sumer we will be introducing a simple native runtime module. This is because technical complexities and tradeoffs associated with the previous iterations of the content directory were not acceptable.


Enable builder/platform operations role

We are introducing a new working group focused on platform operations. Originally, we had also planned to enable the new "Gateway" role, though this is no longer in the scope of the Sumer release.
