Volition-Based Credit Scoring System Development
We build decentralized credit scoring protocols on volition networks. Your users' sensitive personal data remains securely off-chain, while scoring proofs and identity attestations are verifiable on-chain for trustless lending and compliance.

Architectural Comparison
Volition vs. Traditional & On-Chain Scoring
A technical breakdown of how volition-based scoring fundamentally differs from legacy and purely on-chain alternatives, highlighting key advantages for FinTech and DeFi applications.
| Scoring Factor | Traditional Credit Scoring | On-Chain Scoring | Volition-Based Scoring (Chainscore) |
|---|---|---|---|
Data Sources | Limited bureau data, bank history | On-chain transactions only | Multi-source: On-chain + verified off-chain data |
User Privacy & Control | None (data owned by bureaus) | Full transparency (all data public) | User sovereignty via zk-proofs & selective disclosure |
Developer Integration | Months of compliance & API work | Weeks, but limited utility | Days with our modular SDK & APIs |
Risk Model Accuracy | Moderate, lacks Web3 context | Low, misses off-chain identity | High, holistic financial portrait |
Regulatory Compliance | Built-in but rigid | Challenging (pseudonymity) | Designed for compliance (GDPR, GLBA-ready) |
Real-Time Updates | Batch updates (monthly) | Real-time (on-chain only) | Real-time hybrid data sync |
Implementation Cost | $200K+ annual licensing | $50K-$100K dev cost | From $75K one-time + optional SLA |
Time to Live API | 3-6 months | 4-8 weeks | 2-4 weeks |

Volition-Based Credit Scoring
Frequently Asked Questions
Get clear answers on our development process, security, and outcomes for building a custom, on-chain credit scoring system.
A volition-based credit scoring system is a decentralized protocol that allows users to selectively disclose their financial data to generate a credit score. Unlike traditional models that aggregate data without explicit consent, our systems give users control. We build using zero-knowledge proofs (ZKPs) and verifiable credentials to enable users to prove creditworthiness (e.g., "I have an income > $100k") without revealing the underlying transaction history. This shifts the paradigm from surveillance-based scoring to permissioned, privacy-preserving assessment.
