BUILDING BLOCKS FOR TRUST
Core Schema Design Capabilities
Our foundational service delivers production-ready, interoperable schemas that form the bedrock of your credential ecosystem. We focus on security, scalability, and real-world utility from day one.
02
Domain-Specific Data Modeling
We translate complex business logic—from KYC/AML to professional certifications—into precise, machine-readable schemas. This ensures your credentials carry the exact semantic meaning required for automated trust.
04
Cross-Protocol Interoperability
Design schemas that work seamlessly across ecosystems. Our designs are compatible with ION (Sidetree), Ethereum Attestation Service (EAS), and other leading attestation protocols out of the box.
05
Governance & Versioning Frameworks
We implement robust schema lifecycle management, including version control, deprecation policies, and upgrade paths. This prevents fragmentation and maintains trust as your standards evolve.

Strategic Decision Matrix
Build vs. Buy vs. Generic Schema
Choosing the right approach for your verifiable credential schemas impacts security, time-to-market, and long-term flexibility. This comparison highlights the trade-offs between building custom schemas in-house, using generic public templates, and partnering with Chainscore Labs for a tailored, production-ready solution.

Our process follows a structured 4-phase methodology: 1. Discovery & Requirements (1 week): We analyze your use case, data model, and compliance needs. 2. Schema Architecture (1-2 weeks): We design the credential structure, define JSON-LD contexts, and map to W3C standards. 3. Implementation & Testing (2-3 weeks): We develop the schema, create issuer/verifier libraries, and conduct security and interoperability testing. 4. Deployment & Documentation (1 week): We assist with on-chain registry deployment (e.g., Ethereum, Polygon) and deliver comprehensive technical docs. This ensures a predictable, transparent path from concept to production.
