Decentralized Identity and/or Self Sovereign Identity (SSI) is a new cryptographic technology that enables entities to assert ownership of their identity, where the identity remains private and not disclosed during transactions in decentralized ecosystems.
Decentralized Identifiers (DIDs) are identifiable endpoints belonging to a SSI, and can be shared with the world. This includes documents, wallets, smart contracts, or programmable agents. In a decentralized system, DIDs are embedded in Verifiable Credentials (or VCs). VCs may be created by trusted entities, such as government agencies, businesses, universities, or employers, and issued to a “holder” of the VC. If we think of the DID as a global ID, then VCs are like digital passports, or unique stamps which serve to attest to specific information about an entity associated with a specific DID.
A Self-Sovereign Digital Twin™ (SSDT) is a digital twin which is anchored in a decentralized trust network using W3C’s DIDs Standard (for MOBI’s community, this is the Integrated Trust Network, or ITN). By using the SSDT and W3C’s VC Standard, the controller of the SSDT can participate as an autonomous economic agent in trusted transactions through issuing VCs and Verifiable Presentations (VPs). For MOBI’s community, this is done using Citopia Marketplace. Citopia utilizes the network effect and Zero-Knowledge (ZK); allows for the onboarding of SSDT; and enables VCs and VPs.
Citopia SSDT is a universal translator and encrypted lock data vault that no individual or organization has access to other than the owner/controller. The SSDT stores a combination of static and real-time data to log an entity’s journey throughout its lifetime. Citopia uses DIDs, VCs, VPs, and ZK to ensure data privacy and security.
