# Fraud Resistance

The protocol guards against several fraud vectors, following patterns established by protocols like Goldfinch.

***

## Fraudulent Seller, Honest Investors

**Scenario:** A seller submits fake invoices for non-existent goods.

{% @mermaid/diagram content="flowchart LR
S\["Fraudulent<br/>Seller"] -->|"Fake invoice"| P\["Platform"]
P -->|"Funds"| S
I\["Honest<br/>Investors"] -->|"Capital"| P
P -->|"Nothing"| I" %}

### Guards

| Guard                    | Description                             |
| ------------------------ | --------------------------------------- |
| **Verification Process** | Documents cross-referenced with debtors |
| **Debtor Confirmation**  | Direct outreach to confirm obligation   |
| **Seller Staking**       | Sellers stake collateral against fraud  |
| **Legal Recourse**       | Off-chain agreements enable prosecution |
| **Reputation System**    | New sellers face stricter scrutiny      |

### Why It's Hard to Pull Off

{% stepper %}
{% step %}
Verifiers contact debtors directly.
{% endstep %}

{% step %}
Fake debtors are detectable.
{% endstep %}

{% step %}
Seller stake provides immediate loss.
{% endstep %}

{% step %}
Legal consequences for fraud.
{% endstep %}

{% step %}
Platform ban prevents repeat attempts.
{% endstep %}
{% endstepper %}

***

## Seller-Investor Collusion

**Scenario:** A seller colludes with investors to extract capital.

{% @mermaid/diagram content="flowchart LR
S\["Seller"] <-->|"Collusion"| I\["Fake<br/>Investors"]
S -->|"Fake invoice"| P\["Platform"]
I -->|"'Invest' "| P
P -->|"Funds"| S
S -->|"Split proceeds"| I" %}

### Guards

| Guard                   | Description                             |
| ----------------------- | --------------------------------------- |
| **KYC/KYB Separation**  | Verification that parties are unrelated |
| **Debtor Independence** | Debtors must be third parties           |
| **Pattern Detection**   | Monitoring for suspicious relationships |
| **Multiple Investors**  | Large assets require multiple funders   |

### Why It's Hard to Pull Off

{% stepper %}
{% step %}
KYC shows if parties are related.
{% endstep %}

{% step %}
Debtor must be real, independent company.
{% endstep %}

{% step %}
Unusual patterns trigger review.
{% endstep %}

{% step %}
Requires fooling multiple parties.
{% endstep %}
{% endstepper %}

***

## Verification Manipulation

**Scenario:** Verifiers approve invalid assets for bribes.

{% @mermaid/diagram content="flowchart LR
S\["Fraudulent<br/>Seller"] -->|"Bribe"| V\["Corrupt<br/>Verifier"]
V -->|"Approve"| P\["Platform"]
S -->|"Fake asset"| P
P -->|"Funds"| S" %}

### Guards

| Guard                  | Description                                    |
| ---------------------- | ---------------------------------------------- |
| **Verifier Staking**   | Stake slashed if approved assets default       |
| **Random Assignment**  | Verifiers randomly selected, hard to predict   |
| **Multiple Verifiers** | High-value assets require multiple approvals   |
| **Reputation System**  | Long-term reputation more valuable than bribes |

### Why It's Hard to Pull Off

{% stepper %}
{% step %}
Can't predict which verifier assigned.
{% endstep %}

{% step %}
Bribing multiple verifiers expensive.
{% endstep %}

{% step %}
Stake loss exceeds potential bribe.
{% endstep %}

{% step %}
Reputation damage ends career.
{% endstep %}
{% endstepper %}

## Fraudulent Investors, Honest Seller

**Scenario:** Investors manipulate a legitimate seller's asset.

{% @mermaid/diagram content="flowchart LR
S\["Honest<br/>Seller"] -->|"Real invoice"| P\["Platform"]
I\["Fraudulent<br/>Investors"] -->|"Manipulate"| P
P -->|"Funds"| S
D\["Debtor"] -->|"Pays"| I" %}

### Guards

| Guard                         | Description                          |
| ----------------------------- | ------------------------------------ |
| **Smart Contract Settlement** | Payments go to escrow, not investors |
| **Transparent Flow**          | All distributions on-chain           |
| **No Early Withdrawal**       | Funds locked until maturity          |

### Why It's Hard to Pull Off

{% stepper %}
{% step %}
Investors can't redirect debtor payments.
{% endstep %}

{% step %}
Settlement is automatic via smart contract.
{% endstep %}

{% step %}
No way to extract more than entitled.
{% endstep %}
{% endstepper %}

***

## Platform Insider Threat

**Scenario:** Platform team member exploits access.

### Guards

| Guard                     | Description                          |
| ------------------------- | ------------------------------------ |
| **Multi-sig Controls**    | No single person controls funds      |
| **Time-locks**            | Delays on sensitive operations       |
| **On-chain Transparency** | All actions visible                  |
| **Limited Access**        | Smart contracts hold funds, not team |

### Why It's Hard to Pull Off

{% stepper %}
{% step %}
Funds in smart contracts, not team wallets.
{% endstep %}

{% step %}
Multi-sig requires multiple conspirators.
{% endstep %}

{% step %}
Time-lock allows detection before execution.
{% endstep %}

{% step %}
On-chain actions are auditable.
{% endstep %}
{% endstepper %}

No system is 100% fraud-proof. These guards make fraud difficult and expensive, but some risk remains. Diversify investments accordingly.
