Strategic Infrastructure Decision
Build vs. Buy: Custom Privacy Oracle vs. Public Feeds
A quantitative comparison of the total cost, risk, and time investment required to build a privacy-preserving oracle in-house versus deploying a managed solution from Chainscore.
| Factor | Build In-House | Public Feeds (e.g., Chainlink) | Chainscore Custom Oracle |
|---|---|---|---|
Time to Production | 6-12 months | Immediate | 4-8 weeks |
Upfront Development Cost | $250K-$750K+ | $0 (integration only) | $50K-$200K |
Data Privacy Guarantee | Custom (your control) | None (public data) | End-to-end encryption |
Security Posture | High Risk (unaudited, custom code) | High (audited, but public) | Low Risk (audited, private execution) |
Ongoing Maintenance & Updates | 2-3 FTE engineers | Vendor-managed, limited control | Fully managed with SLA |
Custom Logic & Computation | Fully customizable | Limited to public functions | Fully customizable off-chain |
Multi-Chain Support | Custom deployment per chain | Native, but public | Native with private state sync |
Annual Total Cost (Year 1) | $500K-$1M+ | $10K-$50K (service fees) | $75K-$250K (all-inclusive) |
Competitive Advantage | Theoretical, if successful | None (same as competitors) | Direct (unique, private data feeds) |

PROVEN METHODOLOGY
Our Development & Deployment Process
A systematic, security-first approach to delivering production-ready privacy oracles that integrate seamlessly into your existing stack.
01
Architecture & Design Review
We conduct a deep technical assessment of your data requirements and threat model to design a custom oracle architecture. This includes selecting the optimal privacy primitives (ZKPs, MPC, TEEs) and defining the network topology for your specific use case.

Frequently Asked Questions
Get clear answers on timelines, security, and process for building a custom, confidential oracle solution.
A production-ready, audited oracle network typically takes 8-12 weeks from kickoff to mainnet deployment. This includes 2 weeks for architecture design, 4-5 weeks for core development (ZK circuits, on/off-chain components), 2 weeks for internal testing and integration, and 2-3 weeks for external security audits. For simpler integrations or POCs, timelines can be as short as 4-6 weeks.
