Strategic Infrastructure Decision
Build vs. Buy: Custom Protocol vs. Generic Bridges
A detailed comparison of developing a custom Bitcoin L2 messaging protocol in-house versus using a generic bridge-as-a-service, highlighting the long-term strategic and operational impacts.
| Critical Factor | Build In-House | Generic Bridge Service | Chainscore Custom Protocol |
|---|---|---|---|
Time to Initial Deployment | 6-12+ months | 2-4 weeks | 4-8 weeks |
Upfront Development Cost | $250K - $750K+ | $5K - $50K (setup) | $80K - $200K |
Protocol-Level Security | Your responsibility (high risk) | Shared risk (depends on provider) | Formally audited, dedicated security |
Custom Logic & Business Rules | Fully customizable | Limited to provider templates | Tailored to your specific use case |
Sovereignty & Control | Full control | Vendor-locked, limited control | You own the protocol & keys |
Ongoing Maintenance & Upgrades | Internal team required | Managed by provider | Optional Managed Service SLA |
Cross-Chain Fee Optimization | Customizable, requires R&D | Fixed, often opaque fees | Optimized for your token economics |
Integration Complexity | High (build everything) | Low (plug-and-play) | Medium (we handle the core protocol) |
Total Cost of Ownership (Year 1) | $400K - $1M+ | $60K - $150K | $150K - $300K |
Strategic Advantage | Potential differentiator (if successful) | Commoditized, no moat | Differentiated, defensible infrastructure |
