Identity Layer
Introduction
The Identity Layer in SafePulse provides self-sovereign, blockchain-backed digital identity and credentials. It enables users, businesses, and organizations to verify identity and credentials securely, privately, and without reliance on centralized authorities.
This layer is designed for:
- Individuals: managing personal identity and credentials
- Organizations: verifying employee, partner, or vendor credentials
- Developers: integrating decentralized identity and verifiable credentials into smart contract workflows
All services in this layer are built on open standards to ensure interoperability, privacy, and security.
Layer Overview
| Layer Name | Description | Services |
|---|---|---|
| Identity Layer | Provides self-sovereign identity and verifiable credentials for secure, decentralized verification | Decentralized Identity (DID), Verifiable Credentials (VCs) |
Key Objectives of the Layer:
- Provide user-controlled, portable digital identities
- Enable secure verification without centralized intermediaries
- Support verifiable presentations for privacy-preserving data sharing
- Integrate seamlessly with SafePulse’s contracts and document services
Services in Identity Layer
1. Decentralized Identity (DID)
Purpose: Enable lightweight, self-sovereign digital identity that is fully user-controlled, portable, and privacy-preserving.
Key Features:
- Based on ERC-1056 Ethereum standard
- Fully user-controlled – no centralized authority required
- Portable
- Compatible with W3C verifiable credentials v2.0
- Secure and cryptographically verifiable
How It Works:
- User creates a DID linked to their blockchain wallet.
- The DID stores essential metadata and public keys/delegates on-chain.
- Users control access to their identity data through wallet authorization.
- Can be used for verifying agreements, documents, and interacting with services.
Use Case Example:
- A freelancer registers a DID to authenticate themselves on multiple platforms, providing a verifiable, tamper-proof identity without relying on centralized providers.
Benefits:
- Self-sovereignty – full user control of identity
- Interoperability – compatible with decentralized apps and smart contracts
- compliance – uport integration
- Security – cryptographic proof of identity, self identifying with EOA's
2. Verifiable Credentials (VCs)
Purpose: Provide wallet-first, blockchain-backed digital credentials that are tamper-proof, privacy-preserving, and verifiable.
Key Features:
- Compliant with W3C Verifiable Credentials v2.0
- Blockchain-backed and tamper-proof
- Supports verifiable presentations
- Can represent education certificates, licenses, compliance documents, or professional credentials
How It Works:
- Credential issuer creates a verifiable credential for a user.
- Credential metadata and proof are recorded on-chain.
- User stores credentials in their wallet and selectively shares informations and proofs with third parties.
- Recipients can verify authenticity without needing direct access to the issuer.
Use Case Example:
- A university issues a blockchain-backed diploma to a graduate. The graduate can present proof to employers without exposing sensitive information, and employers can independently verify its authenticity.
Benefits:
- Trustless Verification – verifiable without a central authority
- Privacy-Preserving Sharing – selective disclosure for sensitive data
- Tamper-Proof – blockchain ensures integrity and immutability
Layer Benefits Summary
| Service | Key Advantages |
|---|---|
| Decentralized Identity (DID) | Self-sovereign, portable, secure identity |
| Verifiable Credentials (VCs) | Blockchain-backed credentials with selective disclosure |
Overall Layer Benefits:
- User-Controlled Identity – Full autonomy over personal or organizational identity.
- Secure Verification – Blockchain ensures authenticity and prevents tampering.
- Privacy & Selective Sharing – Share only what is necessary.
- Integration with SafePulse Services – Identity and credentials can seamlessly interact with payment, document, and content layers.
- Standardized & Interoperable – Built on ERC-1056 and W3C standards for broad compatibility.
The Identity Layer empowers users with trustworthy, self-sovereign digital identity and credentials, enabling secure, verifiable interactions across SafePulse’s ecosystem. By combining DIDs with verifiable credentials, SafePulse supports privacy-preserving, interoperable, and blockchain-backed identity solutions suitable for individuals, businesses, and developers alike.
