Build vs. Buy: Why Specialized Development Wins
A detailed comparison of the time, cost, and risk involved in building a custom reputation system versus leveraging Chainscore's battle-tested solution.
| Key Factor | Build In-House | Chainscore |
|---|---|---|
Time to Production | 6-12+ months | 4-8 weeks |
Initial Development Cost | $250K - $500K+ | $50K - $150K |
Security Audit & Risk | High (custom, unaudited code) | Low (pre-audited, battle-tested models) |
Ongoing R&D & Updates | Your team's full-time focus | Included (protocol evolution) |
Sybil Attack Protection | Requires novel research | Proven multi-faceted defense (PoP, staking, behavior) |
Integration Complexity | High (custom APIs, data pipelines) | Low (modular APIs, SDKs, dashboards) |
Total Cost of Ownership (Year 1) | $400K - $750K+ | $75K - $200K |
Time to First Valid Score | Months of data collection | Weeks (leverages existing patterns) |

Smart Contract Development
Secure, production-ready smart contracts built to your exact specifications.
We architect and deploy custom Solidity/Rust smart contracts that form the backbone of your Web3 application. Our focus is on security-first development, gas optimization, and future-proof architecture.
- Full Lifecycle Development: From initial design and
Hardhat/Foundrytesting to mainnet deployment and verification. - Security Audits: All code undergoes internal review against OpenZeppelin standards, with optional third-party audit coordination.
- Common Deliverables:
ERC-20/ERC-721tokens, staking pools, custom DEX logic, governance modules, and bridging protocols.
We deliver contracts you can trust, with a typical MVP deployment in under 3 weeks and a 99.9% post-launch uptime SLA for critical functions.

Frequently Asked Questions
Get clear answers on how our reputation scoring service integrates with your platform, its security, and the implementation process.
Our system employs a multi-layered methodology combining on-chain behavior analysis, zero-knowledge proof verification, and proprietary graph analysis. We analyze wallet interactions, transaction patterns, and asset holdings across 15+ EVM chains to create a unique, non-transferable reputation score that is cryptographically resistant to manipulation. This prevents users from creating multiple fake identities (Sybils) to game your platform's rewards or governance.
