Architectural Comparison
Custom Sync vs. Generic Bridging Solutions
A technical and operational breakdown of building a purpose-built oracle synchronization layer versus using a generic message-passing bridge.
| Key Factor | Generic Bridging Solution | Chainscore Custom Sync |
|---|---|---|
Architecture Purpose | Generalized message passing | Optimized for oracle state & price feeds |
Data Latency | High (5-30 min finality) | Low (< 2 sec for critical data) |
Security Model | Shared bridge validator set risk | Isolated, application-specific security |
Development & Integration Time | 2-4 weeks (standard bridge SDK) | 4-8 weeks (custom design & audit) |
Ongoing Operational Overhead | Your team manages relayers & monitoring | Fully managed service with 99.9% SLA |
Cost Efficiency for High-Volume Data | Inefficient (pay per generic message) | Optimized (batch updates, cost-sharing) |
Custom Logic & Data Transformation | Not possible (raw data only) | Fully customizable aggregation & validation |
Typical Total Cost of Ownership (Year 1) | $50K - $150K+ (infra + dev ops) | $80K - $200K (managed service) |
