Node Churning Events

    In the THORChain ecosystem, a "churn" happens when one node goes from "Active" -> "Standby" or "Disabled" and another goes from "Ready" -> "Active". This dashboard shows the cadence of node churning events over time.

    What is churning?

    As new nodes join/leave the network, this triggers a “churning event”. Which means the list of validators that can commit blocks to the chain changes, and also creates a new Asgard vault, while retiring an old one. All funds in this retiring vault are moved to the new Asgard vault. Normally, a churning event happens every 3 days (50,000 blocks), although it is possible for it to happen more frequently.

    How often do they really happen?

    Over the past year, the number of churns per month varies a lot. The minimum amount is 2 churns in both April and November of 2021, while the maximum was 10 per month, occurring 4 times.

    Conclusion

    Churning is an important part of the THORChain ecosystem and helps keep things in check. The amount of churns per month could be because of a variety of different reasons, so further analysis would be needed to form a full conclusion. I suspect as the use of THORChain increases or decreases, the amount of churns follows.
