Strategic Decision Analysis
Build vs. Buy: Custom vs. Generic Oracle Feeds
A technical and operational comparison between developing a validator-resistant data feed in-house versus partnering with Chainscore Labs for a custom solution.
| Key Factor | Build In-House | Generic Oracle Service | Chainscore Custom Feed |
|---|---|---|---|
Time to Production | 6-12 months | 1-2 weeks | 4-8 weeks |
Upfront Development Cost | $150K - $400K+ | $0 - $10K (API fees) | $50K - $150K |
Security Posture | High Risk (unaudited, novel attack vectors) | Medium Risk (shared, audited but generic) | Low Risk (custom-audited, validator-resistant design) |
Data Customization & Logic | Full control | Limited to provider's feeds | Tailored to your dApp's exact needs |
Validator Resistance & MEV Protection | Your team's research & implementation | Not guaranteed | Core architecture principle |
Ongoing Maintenance & Updates | Full-time dev team required | Managed by provider | Optional SLA with 24/7 monitoring |
SLA for Uptime & Latency | Your responsibility (target 99.5%) | Provider's SLA (typically 99.9%) | 99.95% Uptime SLA with sub-second latency |
Total Cost of Ownership (Year 1) | $300K - $700K+ | $15K - $50K+ (recurring fees) | $80K - $200K (fixed project + optional SLA) |

Solana Data Feeds
Frequently Asked Questions
Common questions about developing validator-resistant, high-frequency data feeds on Solana.
A validator-resistant data feed is an oracle system designed to remain operational and accurate even if a significant portion of the Solana validator network is compromised or experiences downtime. This is critical because Solana's high throughput (65,000+ TPS) and sub-second block times demand data feeds that are not only fast but also exceptionally resilient. Our architecture uses a multi-layered approach combining on-chain aggregation with off-chain consensus to prevent any single validator or group from manipulating the data, ensuring your DeFi, trading, or prediction market protocol remains secure and reliable.
