Build vs. Buy: Custom DID vs. Legacy Auth & KYC
A detailed comparison of development approaches for user authentication, highlighting the operational and financial impact of building a custom Decentralized Identity (DID) system versus using Chainscore's managed service versus maintaining legacy solutions.
| Feature / Factor | Build In-House DID | Chainscore Managed DID | Legacy Auth & KYC |
|---|---|---|---|
Time to Production Launch | 6-12 months | 4-8 weeks | 2-4 weeks (integration) |
Upfront Development Cost | $150K - $400K+ | $25K - $75K | $10K - $30K (vendor fees) |
Ongoing Annual Cost (Maintenance, Compliance) | $80K - $200K | $15K - $50K (SLA optional) | $50K - $150K (licensing + KYC checks) |
Security & Audit Burden | High (Your team's responsibility) | Low (Pre-audited modules, ongoing monitoring) | Medium (Vendor risk, data breach liability) |
Protocol Flexibility & Upgrades | Full control, but you manage upgrades | Managed upgrades for W3C standards, ERC-725/734 | Vendor-locked, slow to adopt new standards |
User Data Sovereignty & Privacy | Full user sovereignty (Zero-Knowledge Proofs) | Full user sovereignty (Zero-Knowledge Proofs) | Centralized storage, high privacy risk |
Compliance (Travel Rule, AML) Integration | Must build and maintain custom integrations | Pre-built modular integrations available | Bundled, often inflexible and expensive |
Cross-Chain / Multi-Protocol Support | Significant additional development required | Native support for EVM, Solana, Cosmos SDK | Typically not supported |
Team Required | 3-5 Senior Blockchain Devs + Security Auditor | Your existing product team + our specialists | DevOps & vendor management |
Technical & Commercial Insights
DID Integration for Banking: FAQs
Answers to the most common questions from financial institutions evaluating decentralized identity solutions.
A standard DID integration for KYC/AML and user login takes 4-8 weeks from kickoff to production. This includes requirements analysis, smart contract development, frontend SDK integration, and security audits. We use a phased delivery model, with a pilot-ready MVP often available within 3 weeks. Complex integrations with existing core banking systems may extend this timeline, which we scope and agree upon upfront.
