FROM LEGACY TO LEADERSHIP
Business Outcomes of a Modern RNG Oracle
Migrating to a modern, on-chain RNG oracle delivers measurable improvements in security, cost, and user trust. These are the concrete outcomes our clients achieve.
01
Provably Fair & Verifiable Randomness
Replace opaque, centralized RNG with on-chain, cryptographically verifiable randomness (VRF). Every result is publicly auditable, eliminating trust assumptions and building user confidence.
100%
On-Chain Proof
0 Trust

02
Eliminate Single Points of Failure
Decouple your application's core logic from legacy RNG API dependencies. Achieve true decentralization with a resilient, multi-chain oracle network for 24/7 uptime.

Technical & Operational Analysis
Legacy vs. Modernized RNG: A Clear Comparison
A detailed comparison of traditional Random Number Generation systems versus modern, on-chain oracle solutions, highlighting the technical and business impact of migration.
| Evaluation Factor | Legacy RNG System | Chainscore Oracle Solution |
|---|---|---|
Architecture & Integration | Monolithic, vendor-locked APIs | Decentralized, smart contract-native oracles |
Verifiable Randomness | Opaque, trust-based output | Cryptographically verifiable on-chain (e.g., VRF) |
Latency to On-Chain Use | High (seconds to minutes) | Low (< 2 seconds to finality) |
Security & Auditability | Black-box process, high audit cost | Transparent, pre-audited protocols (Chainlink VRF, Drand) |
Uptime & Reliability SLA | Typically 99.5% (downtime risk) | Guaranteed 99.9% with decentralized fallbacks |
Development & Integration Time | 3-6 months for custom integration | 2-4 weeks for production-ready deployment |
Ongoing Operational Cost | High (licensing, dedicated infra) | Predictable, pay-per-request gas model |
Scalability for High-Volume Use | Bottlenecks under load (e.g., gaming mints) | Horizontally scalable across multiple chains |
Total Cost of Ownership (Year 1) | $150K - $300K+ | $25K - $75K |

Technical & Process Questions
RNG Migration & Integration FAQs
Get clear answers on timelines, security, and process for migrating your legacy random number generation to a secure, decentralized oracle.
A standard migration from a centralized or legacy RNG to a decentralized oracle like Chainlink VRF takes 2-4 weeks from kickoff to mainnet deployment. This includes architecture review, smart contract development, integration testing, and security audit. Complex protocols with multiple dependencies or custom randomness logic may extend to 6-8 weeks. We provide a detailed project plan with milestones in the first week.
