ENTERPRISE-GRADE SECURITY ARCHITECTURE
Core Components of Our On-Chain Fraud Prevention
Our system integrates multiple layers of detection and prevention, built on verifiable on-chain data to eliminate invalid traffic and protect your ad spend.
01
Real-Time Bot Detection Engine
Proprietary algorithms analyze wallet transaction patterns, timing, and on-chain footprints in real-time to identify and block sophisticated botnets and Sybil attacks before they interact with your campaigns.

Infrastructure Decision Matrix
Build vs. Buy: On-Chain vs. Traditional Fraud Prevention
A technical and economic comparison of developing an ad fraud prevention system in-house versus partnering with Chainscore for a custom, on-chain solution.
| Decision Factor | Build In-House | Buy with Chainscore |
|---|---|---|
Time to Production MVP | 6-12 months | 4-8 weeks |
Initial Development Cost | $250K - $600K+ | $50K - $150K |
Core Technology | Traditional ML/DB (High false positives) | On-Chain Attribution & ZK-Proofs (Tamper-proof) |
Security Posture | High Risk (Custom, unaudited code) | Enterprise-Grade (Audited smart contracts, bug bounties) |
Data Integrity | Centralized DB (Vulnerable to manipulation) | Immutable On-Chain Ledger (Transparent & verifiable) |
Team Requirements | 5-10 FTEs (Solidity, Data Science, DevOps) | Your Product Team + Our Experts |
Ongoing Maintenance | Full internal team burden (updates, attacks) | Managed SLA with 99.9% uptime |
Adaptation to New Fraud Vectors | Slow (requires re-engineering) | Rapid (protocol-level updates handled by us) |
Total Cost of Ownership (Year 1) | $500K - $1.2M+ | $80K - $200K |
Proof for Advertisers | Custom reports (trust-based) | Verifiable on-chain settlement proofs |

Ad Fraud Prevention for Web3: Key Questions
Get clear answers on our process, timeline, and technical approach for building a robust, on-chain ad fraud prevention system.
A standard Ad Fraud Prevention System deployment takes 4-6 weeks from kickoff to mainnet launch. This includes 1 week for requirements & design, 2-3 weeks for core smart contract development and testing, and 1-2 weeks for integration, final audit, and deployment. Complex multi-chain or custom ML model integrations can extend this to 8-10 weeks.
