# Online Marketplaces

**Scenario:** An online marketplace is struggling with fraudulent buyers and sellers who create fake accounts to manipulate reviews, prices, and transactions, leading to a loss of trust among genuine users.

#### **How** Taτsu **Works:**

* **Identity Aggregation:** Buyers and sellers link their marketplace profiles, payment methods, and other relevant credentials to Taτsu, forming a robust digital identity.
* **Human Score Calculation:** Taτsu assigns a human score based on the user’s transaction history, reviews, and engagement with the marketplace.
* **Decentralized Verification:** The marketplace uses Taτsu’s decentralized verification to authenticate users before they can list products or make purchases. Users with low human scores are flagged for further review or restricted.
* **Identity Proof:** Verified users receive a digital credential that they use to authenticate their actions on the marketplace, ensuring that all transactions are conducted by real, trustworthy individuals.

**Outcome:** The marketplace sees a reduction in fraudulent activity, with more transparent and secure transactions. Trust among buyers and sellers is restored, leading to increased activity and satisfaction.
