The transitional Cohort 2.1

About Cohort 2.1

Cohort 2.1 is a transitional cohort that will take place between Cohorts 2 & 3.

It consists of a selection of Polkadot nodes and all Kusama nodes that participated in Cohort 2. It will run approximately for 2 months, between the end of Cohort 2 on July 17 and the start of Cohort 3 on September 10, 2025.

There was no application process for Cohort 2.1. The DN Committee selected the Polkadot nodes from the Cohort 2 participants, and all Kusama nodes will continue in Cohort 2.1.

The reason this transitional cohort was needed is because Web3 Foundation needs to rebalance their Polkadot stashes to be prepared for the upcoming increases to the active set, so they can continue to nominate the maximum number of nodes possible.

Important information

Web3 Foundation’s nominations aim to put all selected validators in the active set. However, because of the way the election algorithm works, it is possible that some nodes might not become active. In any such a case, we’ll do our best to adjust the nominations accordingly, but we cannot guarantee all selected validators will be active all the time.

For anyone participating in the program, please read the Rules and Terms and Conditions once more and make sure you comply at all times.
