Technical & Operational Comparison

ZK Fraud Engine vs. Traditional Methods

A detailed breakdown of how a StarkNet Cairo-based ZK Fraud Detection Engine fundamentally outperforms conventional fraud prevention systems in Web3, focusing on security, performance, and cost-effectiveness.

Comparison FactorTraditional Methods (e.g., Oracles, Heuristics)Chainscore ZK Fraud Engine

Detection Method

Off-chain data feeds, pattern matching

On-chain, cryptographically-verified state proofs

Security Guarantee

Trusted third-party oracles

Trustless, mathematically-proven validity

False Positive Rate

High (5-15%) due to lag/approximations

Near-zero (<0.1%) via deterministic logic

Detection Latency

Minutes to hours for data aggregation

Frequently Asked Questions

Get clear answers on our development process, security, and support for custom ZK fraud detection engines on StarkNet.

A complete end-to-end deployment typically takes 4-8 weeks. This includes a 1-week discovery and scoping phase, 2-4 weeks for core Cairo smart contract development and off-chain logic, 1 week for integration testing on StarkNet testnet, and a final week for mainnet deployment and handover. Complex engines with novel proof circuits may extend this timeline.
