FROM LEGACY TO SELF-SOVEREIGN
Business Outcomes of a DID Migration
Migrating from a federated identity system to Decentralized Identifiers (DIDs) delivers concrete operational and strategic advantages. These are the measurable outcomes our clients achieve.
01
Eliminate Vendor Lock-In
Break free from proprietary identity providers. We implement W3C-standard DIDs and Verifiable Credentials, giving you full control over your identity layer and data portability.

Architectural Comparison
Federated Identity vs. Decentralized Identity
A technical breakdown of legacy identity models versus the self-sovereign, blockchain-based approach we implement for clients.
| Architectural Factor | Federated Identity (Legacy) | Decentralized Identity (DID) |
|---|---|---|
Identity Ownership & Control | Held by centralized providers (e.g., Google, Okta) | Held by the end-user via cryptographic keys |
Data Storage & Custody | Centralized provider databases (vulnerable to breaches) | User-managed wallets & decentralized storage (e.g., IPFS, Ceramic) |
Interoperability & Portability | Limited to pre-established trust frameworks; vendor lock-in | Universal standards (W3C DID/VC); portable across any compliant platform |
Verification & Trust Model | Provider-centric; relies on central authority's reputation | Cryptographic proofs (signatures, ZKPs); trust is decentralized and verifiable |
User Consent & Privacy | Implicit, broad consent; data sharing is opaque | Selective disclosure; user grants explicit, granular permissions |
Development & Integration Time | Months for complex SSO and compliance mapping | Weeks with our SDKs and pre-built Verifiable Credential schemas |
Ongoing Compliance Burden | High (GDPR, CCPA, SOC2 audits on your systems) | Reduced; shifts burden to credential issuers and user consent |
Typical Implementation Cost (Year 1) | $200K+ in development, maintenance, and risk | $50K - $150K for a production-ready, audited migration |

Our Phased Migration Methodology
Our proven, step-by-step approach ensures your transition from federated identity to decentralized identity is secure, compliant, and non-disruptive. We de-risk the process with parallel systems, rigorous testing, and zero-downtime cutovers.
01
Phase 1: Discovery & Architecture
We conduct a full audit of your existing identity stack (OAuth2, SAML, OIDC) and map user flows to define the optimal DID (Decentralized Identifier) and VC (Verifiable Credential) architecture. This includes selecting the appropriate DID method (did:ethr, did:key, did:web) and designing the credential schema.

Phase 2: Parallel Development & Staging
We build your new DID-based authentication layer in a staging environment that runs in parallel with your production system. This allows for comprehensive integration testing, user acceptance testing (UAT), and performance benchmarking without impacting live users.

Phase 3: Gradual User Migration
We implement a controlled, phased rollout using feature flags and canary releases. Users are migrated in cohorts (e.g., internal teams first, then early adopters) with automatic fallback to the legacy system, ensuring a seamless experience and immediate issue resolution.

Phase 4: Full Cutover & Legacy Decommissioning
Once all user cohorts are successfully migrated and validated, we execute the final cutover. We then decommission the legacy identity providers, archive audit trails, and provide a post-migration report detailing performance gains, cost savings, and security improvements.

Technical & Commercial Questions
Federated to DID Migration FAQs
Get clear, specific answers about migrating your legacy identity system to a decentralized, user-owned model. We cover timelines, costs, security, and our proven delivery process.
A standard migration from federated identity (e.g., OAuth, SAML) to Decentralized Identifiers (DIDs) takes 4-8 weeks from kickoff to production deployment. This includes architecture design, smart contract & SDK development, integration, security audit, and user migration planning. Complex enterprise systems with multiple legacy providers may extend to 12 weeks. We provide a detailed project plan with weekly milestones during discovery.
