Battery Self-Sovereign Digital Twin: Digital Storage for Battery Information
The battery SSDT is where the information about a battery resides. Conceptually, the battery SSDT can store and receive information about the battery from outside sources, respond to internal and external queries, and verifiably assert its identity and the information it stores/presents. What is unique about the battery SSDT is that an outside issuing entity is not required, unlike travel passports that are issued by our governments. Because the battery SSDT leverages self-sovereign identity, the battery can assert its own identity with the help of an external trust anchor.
The battery SSDT includes information about the battery’s owner, birth certificate, material and component attributes, maintenance history, warranty and recall logs, charging history, state of health, and may even have the capability to issue payments for services performed on the battery.
Battery SSDTs are onboarded and managed via Citopia, a federated Web3 marketplace for business automation and trustless multiparty track-and-trace.
The controller of the battery SSDT can participate in seamless transactions (including data sharing) by issuing Verifiable Credentials (VCs) and Verifiable Presentations per W3C’s VCs Standard. Citopia leverages zero-knowledge proofs and other advanced cryptographic methods to give users control over who sees their data and how that data is used.
SSDTs on Citopia are linked to a trust anchor such as the Integrated Trust Network (ITN) using Decentralized Identifiers (DIDs) per W3C’s DIDs Standard. Both Citopia and the ITN are member-owned and operated.
