FlatFeeStack: Fraud Resistant Multiplier Feature

Open-source software development relies heavily on community support and financial contributions.
This Term Project presents a novel extension to the existing sponsorship platform FlatFeeStack. This
project introduces two critical innovations: a Multiplier Option and a comprehensive Fraud Prevention
Mechanism.
The Multiplier Option enables foundations to conditionally sponsor open-source repositories, wherein
donations are triggered only after an initial user sponsorship. This approach establishes a collabo-
rative funding model designed to encourage broader community participation. At the same time, it
preserves the core values of FlatFeeStack: making the donation process as equitable, fair, and trans-
parent as possible.
The Fraud Prevention Mechanism incorporates a sophisticated health scoring system that evalu-
ates Git metrics and various internal sponsoring activities. Together, these six metrics form the Health
Value. The scoring model enables administrators to review and evaluate repository assessments, al-
lowing them to decide whether to certify the repository based on the provided evaluation. Moreover,
only repositories within sponsoring bundles that include at least one verified repository are eligible to
receive multiplier funding.
By integrating these features, the extension addresses key challenges in open-source funding,
namely incentivize sponsorship and mitigating potential fraudulent activities. The implementation
demonstrates a flexible, security-conscious approach to supporting open-source ecosystem sustain-
ability.
