Fraud Prevention & Brand Safety: Integrity Built Into Every Impression

Trust is the foundation of digital advertising performance.
As programmatic complexity increases, advertisers need confidence that every impression is human, viewable, and shown in the right environment.
Blockchain-Ads, supported by Nexus Clouds’ verification infrastructure, embeds fraud prevention and brand safety into every stage of the media process — before, during, and after delivery.

Pre-Bid Verification

Before an ad is served, Blockchain-Ads’ pre-bid filters analyze each request in real time using verified datasets from Nexus Clouds.
The system evaluates factors such as domain reputation, app authenticity, historical engagement patterns, and device signals.
Only inventory that meets quality and compliance thresholds is eligible for bidding — reducing exposure to invalid or low-quality traffic before spend occurs.

Post-Bid Validation

After delivery, campaigns undergo continuous validation to ensure impressions remain compliant with targeting and visibility requirements.
Post-bid checks verify metrics like viewability, engagement time, and placement integrity.
All verification events are stored in a transparent audit layer, providing advertisers with complete traceability and accountability.

Human QA Layer

While automation handles large-scale verification, human oversight ensures accuracy across sensitive and high-value verticals.
Blockchain-Ads’ internal QA teams review flagged placements and high-impact campaigns manually, identifying patterns that automated systems might overlook.
This hybrid approach — combining AI, verified data, and human validation — strengthens fraud detection and maintains quality consistency.

Brand Safety Controls

Advertisers retain full control over where and how their ads appear.
Through domain and app allowlists, category exclusions, and custom brand safety parameters, campaigns can align precisely with brand values and compliance standards.
For regulated sectors such as finance, gaming, and crypto, additional moderation protocols safeguard against non-compliant or unsuitable inventory.

Transparency and Immutable Records

Every verification event — pre-bid decision, post-bid validation, and manual review — is recorded in the Blockchain-Ads data layer powered by Nexus Clouds.
This creates an immutable audit trail, ensuring brands can verify delivery authenticity at any time without relying on external intermediaries.
