How to Attack and Defend QF

Slide 16

Slide 16 text

1.Sybil Attack: create multiple accounts to manipulate the QF mechanism 2. Collusion: coordination powered by bribery On QF, identity is the most important infrastructure. Attack vector for QF https://www.gitcoin.co/blog/how-to-attack-and-defend-quadratic-funding

Since an increased number of contributions results in more matching funds, An attacking will 1. create a fake grant, 2. donate to himself, 3. collect matching funds more than the donated budget splitting the contribution into multiple accounts, and donating to themselves. 1. Sybil Attack https://www.gitcoin.co/blog/how-to-attack-and-defend-quadratic-funding

Gitcoin requires to connect with other identity apps, it’s like a DID aggregator. then, calculate “Humanity Score” If humanity score is not high, your voting power will decrease than other donors. = hard to create multiple accounts by 1 person solution: require to connect with other identity apps https://passport.gitcoin.co/#/dashboard

Donate by real account (not Sybil attack), but cooperate in underground 1.Send money (budget) to each other 2.Donate to both projects each other 3.They’ll get more than the budget It’s hard to de fi ne what’s collusion or just community coordination 2.

Where going on?

Slide 32

Slide 32 text

• The current election system has an incentive to target advanced-age • Is the result “general will” (ڞಉҙࢤ)?

Slide 33

Slide 33 text

If we can change the current voting system Now: the number of votes ↓ Will?: how much pluralistic of vote

Slide 34

Slide 34 text

Case study: QF vs Plural QF • QF system will distribute the budget for each project based on the total sum of the donation Q. When your local government uses the QF system to decide a budget for each public goods project, if some projects are targeted to old people they will get much more donations than others. And of course, they get much more budget from the matching pool. Is it collusion? Or, just coordination?

Slide 35

Slide 35 text

Plural QF fix this • When we use the Plural QF system to decide a budget for each public goods project, it can fi x it. • Change the system: Amount of donation→how much pluralistic among donor 1. Donors will clustering by age 2. Projects supported by range receive more priority to receive funds from the matching pool
