ENTERPRISE-GRADE IDENTITY INFRASTRUCTURE

Core Technical Capabilities We Deliver

We build the foundational identity layer that powers compliant, scalable, and user-centric data licensing applications. Our solutions are engineered for production from day one.

W3C DID & VC Protocol Implementation

Full-stack implementation of Decentralized Identifiers (DIDs) and Verifiable Credentials (VCs) compliant with W3C standards. We ensure interoperability across ecosystems like ION (Bitcoin) and Sidetree protocols.

W3C Compliant

Standard

ION / Sidetree

Protocols

Zero-Knowledge Proof (ZKP) Integration

Implement selective disclosure and privacy-preserving proofs using Circom and zk-SNARKs. Enable users to prove credential validity (e.g., KYC status, subscription tier) without revealing underlying data.

Proof Generation

Smart Contract-Based Licensing Engines

Custom Solidity contracts that enforce data usage rights, automate royalty distribution, and manage license issuance/revocation. Built with OpenZeppelin security patterns and upgradability.

PROVEN FRAMEWORK

Our Implementation Methodology

We deliver production-ready decentralized identity systems using a structured, four-phase approach that minimizes risk and accelerates your time-to-market.

Architecture & Protocol Design

We design your system architecture, select optimal standards (W3C DIDs, Verifiable Credentials), and define the tokenomics for your data licensing model.

BUILT ON VERIFIABLE FOUNDATIONS

Standards & Protocols We Implement

We implement battle-tested, open standards to ensure your data licensing platform is interoperable, secure, and future-proof. Our expertise translates complex specifications into production-ready systems.

W3C Verifiable Credentials

We build with the W3C VC Data Model to issue, hold, and verify tamper-proof digital credentials. This ensures user data licenses are portable, privacy-preserving, and recognized across ecosystems.

Decentralized Identifiers (DIDs)

Implement DIDs (did:ethr, did:key, did:web) to give users self-sovereign control over their identity and data-sharing relationships, eliminating reliance on centralized authorities.

EIP-712: Signed Typed Data

Integrate EIP-712 for human-readable, secure off-chain signatures. Users sign structured data licenses with full context, enhancing security and legal enforceability.

ERC-725 & ERC-735: Identity & Claims

Leverage these Ethereum standards for on-chain identity management and claim issuance/revocation. Ideal for building programmable, blockchain-anchored reputation and attestation systems.

OAuth 2.0 & OIDC Bridges

Build secure bridges between traditional OAuth 2.0/OIDC flows and decentralized identity, enabling seamless user onboarding from existing web2 applications.

Selective Disclosure (SD-JWT)

Implement Selective Disclosure for JWTs (SD-JWT) to enable minimal data disclosure. Users share only specific verified claims from a credential, maximizing privacy.

Decentralized Identity for Data Licensing

Frequently Asked Questions

Common questions from CTOs and product leads about implementing secure, compliant data licensing with decentralized identity.

A complete MVP with core licensing logic and identity verification typically takes 4-6 weeks for a standard deployment. Complex integrations with existing enterprise systems or custom compliance modules can extend this to 8-12 weeks. We follow a phased delivery model, with the first working prototype delivered within 2 weeks of kickoff.
