PSA: Superblock Project Exclusion Does Not Eliminate Reward For Crunchers!

There has been a lot of confusion and misinformation on how the exclusion of projects from the Gridcoin superblock actually affects the POR rewards of crunchers. I would like to take this opportunity to explain how the system is actually affected by project exclusions, and why there is nothing for crunchers to be concerned about.

On Superblocks

Superblocks are generated by the Gridcoin network on average every 24 - 48 hours, and are used to propagate the statistics from the BOINC project servers. This will update user contributions, and thus adjust their magnitude, which in turn affects the payout of every user until the next superblock. Recently, some superblocks have been excluding projects, which means all users who crunched for the excluded project will show a magnitude of zero for that work. As such, they are not paid for that project in the current superblock period. To see all past blocks, and superblocks, please visit any of the Gridcoin block explorers. The one I frequent most is hosted on, here.

The current superblock only includes a single project, Amicable Numbers. As a result, any user who has not been doing work for this project will have a magnitude of zero. Further, all users who have been running Amicable Numbers work are expected to receive exceptionally large amounts of GRC if they stake, until the next superblock. You can check your magnitude on or in your wallet on the overview page:

How the System Corrects for This

There is a metric maintained by the blockchain that records how much a user has been overpaid or underpaid for their contributions over time. As a result, when the problematic superblock has passed GRC rewards will be paid out to users in volumes that return everyone to 100% fulfillment of their POR rewards. What this means for you is:

If you do have magnitude due to having contributed to Amicable Numbers recently, you will be overpaid today ...
