The ToIP Foundation was established as a public resource for the enablement of more trusted communication using verifiable credentials.The depiction of interoperability has been demonstrated in a stack diagram with two hemispereshemispheres: a Governance Stack and a Technical Stack operating in four distinct layers 1) Utility (DLT Blockchain) Layer, 2) Provider (Agent/Wallet) Layer, 3) Credential (Issuer/Verifier/Holder) Layer and 4) Ecosystem (Governance Authority) Layer.
