The Real Cost of In-House Oracle Infrastructure
Build vs. Buy: Why Specialized Development Wins
A detailed comparison of the total cost, risk, and time investment required to build and maintain a decentralized oracle history storage system in-house versus partnering with Chainscore Labs.
| Critical Factor | Build In-House | Partner with Chainscore |
|---|---|---|
Time to Production | 6-12 months | 4-8 weeks |
Initial Development Cost | $250K - $600K+ | $50K - $150K |
Security & Audit Overhead | High (unaudited risk) | Low (pre-audited, battle-tested) |
Ongoing Maintenance & Updates | 2-3 FTE Engineers | Fully Managed Service |
Historical Data Integrity | Your responsibility | Guaranteed via cryptographic proofs |
Multi-Chain Support (EVM, Solana, etc.) | Complex custom integration | Built-in, configurable |
Uptime & Reliability SLA | No guarantee (your infra) | 99.9% Enterprise SLA |
Total Cost of Ownership (Year 1) | $500K - $1.2M+ | $80K - $200K |

Decentralized Oracle History Storage
Frequently Asked Questions
Common questions from CTOs and technical leads evaluating permanent, verifiable data storage for their oracles.
A standard deployment for a new oracle with historical data storage takes 2-3 weeks. This includes integration with your existing oracle node, smart contract deployment for data verification, and configuration of the archival layer. For migrating an existing oracle's history, timelines vary based on data volume but average 3-4 weeks.
