Build vs. Buy: Custom ZK-Rollup vs. Generic Solutions
A detailed comparison of the time, cost, and risk involved in developing a privacy-focused ZK-rollup settlement system in-house versus partnering with Chainscore Labs.
| Factor | Build In-House | Generic Public Rollup | Chainscore Custom Rollup |
|---|---|---|---|
Time to Production | 9-18 months | 2-4 weeks | 6-12 weeks |
Initial Development Cost | $300K - $1M+ | $0 (setup fees only) | $75K - $250K |
Custom Privacy Logic (ZKPs) | Your team builds from scratch | Not available | Designed & implemented for you |
Prover/Verifier Optimization | Requires specialized R&D | Fixed, generic performance | Tailored for your transaction patterns |
Security Audit Burden | High (full stack audit required) | Medium (shared security model) | Low (pre-audited components + optional full audit) |
Ongoing Maintenance & Upgrades | Full-time team (2-3 engineers) | Managed by provider, limited control | Optional SLA with dedicated engineers |
Settlement Finality | Customizable (your risk) | Provider-dependent (5 min - 1 hr) | Configurable (< 2 minutes target) |
Data Availability Strategy | You design & implement | Provider's default (often expensive) | Optimized for cost & security (Celestia/EigenDA) |
Exit & Interoperability | Your responsibility | Limited to provider's bridges | Multi-chain bridge design included |
Total Cost of Ownership (Year 1) | $500K - $1.5M+ | $15K - $50K (recurring fees) | $150K - $400K (all-inclusive) |
