Infrastructure Decision Analysis
Build vs. Buy: Custom Engineered vs. Generic Solutions
A detailed comparison of the time, cost, and risk involved in developing a privacy-preserving, sybil-resistant distribution system in-house versus partnering with Chainscore Labs.
| Key Factor | Build In-House | Generic Third-Party Tool | Chainscore Custom Engine |
|---|---|---|---|
Time to Production | 6-12 months | 2-4 months | 4-8 weeks |
Initial Development Cost | $250K - $600K+ | $50K - $100K (licensing) | $80K - $200K |
Security & Audit Burden | High (Your team's responsibility) | Medium (Vendor's standard audit) | Low (Includes formal verification & audit) |
Custom Logic for Sybil Resistance | Full control, high complexity | Limited to platform features | Designed to your tokenomics |
Privacy Tech Integration (ZKPs, MPC) | Major R&D project | Often not available | Built-in, production-ready modules |
Ongoing Maintenance & Updates | 2-3 FTEs ($200K+/year) | Vendor roadmap (limited influence) | Optional SLA with 24/7 support |
Protocol & Chain Flexibility | Your team's implementation | Locked to vendor's stack | Multi-chain (EVM, L2s, Solana) |
Total Cost of Ownership (Year 1) | $450K - $800K+ | $70K - $120K | $95K - $230K |
Critical Path Risk | High (delays, security flaws) | Medium (vendor risk, black box) | Low (managed delivery, SLAs) |

Frequently Asked Questions
Get clear answers on our methodology, timelines, and security for designing and implementing robust, fair token distribution mechanisms.
Our process follows a four-phase framework: 1) Threat Modeling & Goal Definition – We analyze your tokenomics and identify potential attack vectors. 2) Mechanism Design – We architect a custom solution combining on-chain verification (like proof-of-personhood or zero-knowledge proofs) with off-chain attestations. 3) Implementation & Auditing – We build smart contracts (typically in Solidity 0.8+ with OpenZeppelin) and subject them to internal and third-party audits. 4) Monitoring & Iteration – We deploy monitoring dashboards to detect anomalies post-launch. This methodology has secured over $500M in token distributions for our clients.
