How does the architecture represent the decentralized model?

Future State Implementation

The decentralized essence of the W3C decentralized identity model is “no phone home”. The relying party can verify a presented identity without contacting the issuer. Which is accomplished by providing a “verifiable data registry” which is independent of the issuer, the holder and the verifier.

•TrustGrid implements the W3C conformant VBU as a IPFS persistence layer.

•TrustGrid IPFS persistence layer is a highly efficient VBU that enables the relying to easily verify the complete chain of custody of a credential without having to contact the issuer.

•TrustGrid IPFS VBU provides access to zero-knowledge (no PII) cryptographic methods required to validate the cryptographic integrity of claims / credentials.

There are various definitions of NODE within the context of decentralized ecosystems. (full node, partial node, edge node). Wallet is sometime referred to as an access node, as it enables the user to interact with the ecosystem.

In the strictest sense Wallet represents the web 2.0 concept of account, where users can manage credentials. This concept embraced by TrustGrid
