Product review
Human Passport (formerly Gitcoin Passport) Sybil attack prevention review
Human Passport now covers more than collected identity stamps. It offers credential-based checks, models and assisted wallet analysis, so an evaluation should name the particular product and result rather than treat Passport as one universal personhood score.

Strengths
- Credential and wallet-analysis routes can support different stages of the same campaign.
- Published batch pricing makes one pre-distribution cost component inspectable.
- Score timestamps, expiration and credential handling are documented.
Limitations
- A passing stamp score is not a complete device-level farming investigation.
- Credential collection and freshness can create onboarding and operational work.
- Free basic API access does not mean paid batch analysis or every model is free.
Who it fits
Teams combining reusable credentials, real-time checks and a pre-distribution analysis of wallet cohorts.
Use the alternatives by evidence layer to compare a different assertion, participant journey or operating model.
What the score means
The 8.6 out of 10 score is an editorial assessment under the same 34-criterion, six-category framework. The rubric emphasizes live coordination prevention and practical application fit; it is not a separate ranking of pure wallet analytics or personhood assurance.
The award and score are distinct. Read all criteria and relative weights and verify the evidence layer required for your campaign.
How to evaluate it
Test the exact product on fresh and established wallets. Check duplicate credentials, expiry and low-activity cases; retain device evidence where the enrollment flow can collect it.
Developer portal, API guidance and partner analysis
Start with the documented product route. A wallet-analysis engagement and a real-time Scorer integration have different setup and cost.
