ENTERPRISE-GRADE DATA INFRASTRUCTURE
Core Capabilities of Our Hybrid Oracle Systems
Our hybrid oracle architecture delivers secure, low-latency data feeds by combining the reliability of off-chain computation with the trustlessness of on-chain verification. Built for production-ready applications that cannot afford data downtime or manipulation.
01
Multi-Source Data Aggregation
We aggregate and verify data from 50+ premium and decentralized sources (Chainlink, Pyth, custom APIs) to deliver a single, resilient price feed. Mitigates single-point failures and ensures data integrity for critical DeFi operations like lending and derivatives.

Data Sources
< 1 sec
Update Latency
02
Cryptographically-Verified Off-Chain Computation
Complex computations (TWAPs, volatility indices, custom logic) are performed off-chain with cryptographic proofs (zk-SNARKs, TLSNotary) submitted on-chain. Reduces gas costs by up to 90% compared to pure on-chain execution while maintaining verifiable correctness.

Decentralized Validator Network
A permissionless network of independent node operators secures data delivery. Uses a stake-slashing mechanism and reputation scoring to penalize malicious or unreliable nodes, ensuring liveness and censorship resistance without centralized control.

Strategic Infrastructure Decision
Build vs. Buy: Custom Hybrid Oracle vs. Generic Feeds
A detailed comparison of the costs, risks, and outcomes of building a custom oracle solution in-house versus partnering with Chainscore for a production-ready, secure system.
| Critical Factor | Build In-House | Generic Oracle Feed | Chainscore Custom Hybrid Oracle |
|---|---|---|---|
Time to Production | 6-12 months | 1-2 weeks | 4-8 weeks |
Initial Development Cost | $250K - $750K+ | $0 - $5K (API fees) | $50K - $150K |
Security Audit & Pen Testing | Your responsibility ($50K-$100K) | Provider's responsibility | Included (CertiK, OpenZeppelin) |
Data Source Flexibility | Full control | Limited to provider's list | Custom on/off-chain sources |
Uptime & Reliability SLA | Your team's burden | 99.5% (shared risk) | 99.9% with penalties |
Ongoing Maintenance (Year 1) | 1-3 FTE Engineers | Minimal | Optional SLA from $30K/year |
Custom Logic (e.g., TWAP, MEV protection) | Possible, adds complexity | Not available | Built to specification |
Multi-Chain Deployment | Significant extra work | Often limited | Ethereum, Polygon, Arbitrum, Base included |
Total Cost of Ownership (Year 1) | $400K - $1M+ | $5K - $50K | $80K - $180K |

Frequently Asked Questions
Get clear answers on how Chainscore Labs delivers secure, reliable on/off-chain data feeds for your protocol.
A hybrid oracle aggregates and verifies data from multiple on-chain and off-chain sources (APIs, nodes, other oracles) to deliver a single, tamper-resistant data point to your smart contracts. You need one to build DeFi protocols, prediction markets, or insurance dApps that require high-integrity, real-world data (like prices, weather, or sports scores) without a single point of failure. Our architecture reduces latency by 40% and increases data reliability to 99.9% uptime compared to single-source solutions.
