Standards and regulations

W3C - V.C - V.P - DiD

nChain Identity's SSI solution—comprising the Verifier, Issuer, and Identity Wallet—is built with a modular, scalable, and agile approach. Each phase of development builds upon the previous one, ensuring continuous progress while remaining flexible to new insights, ongoing testing, and user feedback. The process emphasizes iterative improvements, balancing cost, perceived value, and evolving requirements to deliver an optimal product.

Interoperable data

The nChain Identity Platform is constructed based on W3C open standards. This guarantees that individuals can securely store their credentials on any digital wallet that complies with these standards. Additionally, it ensures that any party can authenticate the data's legitimacy regardless of geographical location, provided their verification system aligns with these standards.

Standards for Verifiable Credentials and Decentralized Identifiers

The Verifiable Credentials Standard

A Verifiable Credential (VC) serves as a standardized method to digitally articulate credentials (claims) in a tamper-proof and privacy-preserving manner, ensuring machine-verifiability. Published by the W3C in 2019, the Verifiable Credentials Data Model 1.0 establishes the foundation for this standardized approach.

The Decentralized Identifier (DID) Standard

As per the W3C, decentralized Identities represent a fresh identifier category that facilitates verifiable, decentralized digital identity. DIDs operate autonomously of any organization or identity provider, providing creators with complete control. Each DID is equipped with a cryptographic key pair, where the Issuer's Private Key signs the Verifiable Credential, and the Public Key is openly available on the blockchain. This methodology enables a Verifier to consult the blockchain for the Issuer's DID and associated Public Key when verifying the authenticity of a Verifiable Credential.
