THE VERIFICATION PIPELINE
How Our Multi-Source Verification Works
Our deterministic process aggregates, validates, and delivers high-fidelity on-chain data, ensuring your dApp operates on a single source of truth.
01
Data Ingestion & Aggregation
We connect to multiple RPC providers, indexers, and node operators (including Alchemy, Infura, QuickNode) to create a resilient data mesh. This eliminates single points of failure and ensures continuous data availability.

< 100ms
Ingestion Latency
02
Cross-Validation & Consensus
Our engine performs real-time cross-referencing across all ingested sources. Discrepancies are flagged and resolved using a weighted consensus model, prioritizing data from providers with the highest historical accuracy and uptime.

03
Anomaly Detection & Alerting
Proprietary algorithms monitor for chain reorgs, RPC inconsistencies, and data poisoning attempts. Automated alerts are triggered for engineering teams, and fallback mechanisms are engaged to maintain data integrity.

Normalized API Delivery
Verified data is delivered through a unified, low-latency GraphQL/REST API. This provides a consistent interface for transaction status, token balances, and event logs, abstracting away the complexity of the underlying verification layer.

Technical & Commercial Considerations
Multi-Source Oracle Development: Key Questions
Addressing the most common questions from CTOs and technical founders evaluating custom oracle solutions for DeFi, prediction markets, and enterprise Web3 applications.
A standard multi-source oracle deployment takes 2-4 weeks from specification to mainnet launch. This includes architecture design, smart contract development, off-chain aggregator setup, and security review. Complex integrations with 5+ data sources or custom consensus mechanisms can extend this to 6-8 weeks. We provide a detailed sprint-by-sprint roadmap during the initial scoping call.
