Build vs. Buy: ZK Privacy Oracle vs. Standard Solutions
A detailed comparison of the development effort, risk, and total cost of ownership for building a ZK-Rollup privacy-preserving staking oracle in-house versus using Chainscore's managed service.
| Factor | Build In-House | Standard Oracles | Chainscore ZK Privacy Oracle |
|---|---|---|---|
Development Timeline | 6-12 months | N/A (Pre-built) | 4-8 weeks |
ZK-Circuit Expertise Required | High (Hire specialists) | None | None (We manage) |
Cryptographic Audit & Security | High Risk (Unaudited, custom code) | Medium Risk (Audited, but public data) | Low Risk (Fully audited, privacy-preserving) |
Data Privacy Guarantee | Custom (Your responsibility) | None (Data is public) | Zero-Knowledge Proofs |
Supported Staking Protocols | Custom integration per protocol | Limited to major L1s (e.g., ETH) | Ethereum, Polygon, Arbitrum, Base, Avalanche |
Oracle Update Latency | Your team's responsibility | 5-60 minutes | < 2 minutes |
Uptime & Reliability SLA | Your infrastructure, no SLA | Varies by provider | 99.9% SLA |
Ongoing Maintenance & Upgrades | Full-time dev team required | Provider manages, but limited features | Fully managed with protocol updates |
Total Cost (First Year) | $250K - $600K+ | $10K - $50K (API fees) | $80K - $200K (All-inclusive) |
Time to Reliable Production | High uncertainty, long QA cycle | Fast, but with privacy trade-offs | Predictable, secure, and fast |

Frequently Asked Questions
Get clear answers on how we deliver secure, scalable, and private staking oracles for your protocol.
Our oracle leverages zero-knowledge proofs (ZKPs) to validate staking positions and rewards without exposing sensitive on-chain data. We use zk-SNARKs via Circom and Halo2 to generate proofs that verify staking states are correct, publishing only the proof and a commitment hash to the L1. This allows your protocol to access verified data (e.g., total stake, eligibility) while keeping individual user balances and addresses private.
