DOCAS

Digital Ownership and Credit Attestation System. Technical specifications for self-custody identity and portable credentials.

Current Versionv2.1Published January 2024

DOCAS (Digital Ownership and Credit Attestation System) is a comprehensive framework for self-custody identity and portable credentials. It enables users to own and control their identity data while allowing verifiers to confirm credentials without centralized intermediaries.

The framework is designed to be compatible with existing standards including W3C Verifiable Credentials, DIDs (Decentralized Identifiers), and major identity protocols while adding novel capabilities for privacy-preserving verification and cross-jurisdictional portability.

Core Components /

Self-Custody Identity

Users maintain cryptographic control over their identity credentials. Private keys never leave user-controlled hardware or secure enclaves.

Portable Credentials

Verifiable credentials that move with users across providers. Complete KYC once, reuse across the FreshCredit Ecosystem™.

Zero-Knowledge Proofs

Selective disclosure mechanisms that prove credential validity without revealing underlying personal data.
