For reference, we found @armog’s explanation on GIP-106 helpful for background to the changes that were made to the distribution after this was taken over by the Gnosis core team.
After the Builders team retired and handed over the program to the Gnosis Core team, we reviewed the program’s scheme and database and found that they were poorly designed. The rules for rewarding were not clearly established, allowing individuals running multiple nodes or having multiple withdrawal addresses to harm the program. These gaps did not align with the program’s objectives, necessitating the implementation of additional rules.
This is a difficult issue, where problematic design choices in the initial program needed to be resolved to avoid being gamed. However, we have sympathy for those who entered into the program in reliance on the initial offering.
