Building a Multi-Dimensional ID (plural id) based on Social Graphs and Soulbound Tokens to Prevent the Threat of 'Collusion' in Quadratic Funding
One big risk is when family members, friends, or colleagues collaborate to launch an attack against QF. Specifically, if multiple individuals collude and divide a large donation to vote for the same amount, a significant amount of matching funds will be distributed from the matching pool. Therefore, businesses that adopt QF need to find ways to prevent such attacks. Considering other risks, concepts such as SBTs and Plurality are becoming more popular. It is believed that these concepts will become mainstream in the future. At a Schelling point conference, Glen Weyl discussed the topic of "Plurality*QF" and inspired the idea. It is often the case that collusion occurs within homogeneous groups (clusters) that form similar communities. Therefore, it is proposed to try Pairwise quadratic funding. With this approach, the administrator of grant distribution can adjust the matching ratio based on the clusters of donors. The matching ratio is adjusted to be higher for pairs from different communities compared to pairs from the same community. In addition, it is suggested to consider distributing funds based on SBTs. This can include factors such as Twitter's follow/follower relationships. One approach to address this is to determine the intimacy between IDs that made donations and adjust the distribution accordingly. This may be similar to the concept of Proving Family Relationships with Genome Codes of Hash Values in Idena. However, the problem is that the "intimacy" cannot be measured solely based on Gitcoin accounts. Therefore, it is important for Gitcoin to research and develop a system that can prove relationships such as family or friendship based on other social networks or soulbound systems.
