Infrastructure Decision Matrix
Build vs. Buy: Custom Bridge vs. Generic SDK
A technical and economic comparison of developing a cross-chain IoT data bridge in-house versus leveraging Chainscore's specialized development service.
| Key Factor | Build In-House | Generic SDK | Chainscore Custom Development |
|---|---|---|---|
Time to Production | 6-12+ months | 2-4 months | 4-8 weeks |
Initial Development Cost | $250K - $750K+ | $50K - $150K | $80K - $200K |
Security & Audit Burden | Your responsibility (High Risk) | Shared responsibility (Medium Risk) | We deliver audited code (Low Risk) |
IoT Protocol Support (e.g., MQTT, LoRaWAN) | Custom integration required | Limited or community-built | Pre-built, certified adapters |
Cross-Chain Finality for Data | You architect consensus (Slow) | Depends on SDK (Variable) | Optimized for speed (< 2 sec avg) |
Ongoing Maintenance & Upgrades | Full internal team cost | Your team manages SDK updates | Optional SLA with 24/7 monitoring |
Total Cost of Ownership (Year 1) | $400K - $1M+ | $150K - $300K | $120K - $250K |
Guaranteed Uptime SLA | None (your infrastructure) | Varies by provider | 99.9% with defined penalties |
