Web3 Infrastructure

Together, Citopia and the Integrated Trust Network form our federated Web3 infrastructure for cross-industry interoperability. To use MOBI Web3 Infrastructure, members do not have to know/develop blockchain. Blockchain is used only to anchor World Wide Web3 Consortium (W3C) Decentralized Identifiers. All ecosystem transactions use W3C Verifiable Credentials, along with data schemas developed by MOBI and others such as ISO, IEEE, and SAE.

Together, Citopia and the Integrated Trust Network (ITN) form our federated Web3 infrastructure for verifiable identity, location, and business automation.

The Need for Cross-Industry Interoperability

Across every industry, there exist hundreds of thousands of service providers and governmental agencies, each with their distinct databases, processes, and regulations for managing sensitive business and consumer data.

Currently, automating multiparty business processes necessitates reliance on centralized systems. However, in vast and complex networks where trust incurs significant frictional costs, these centralized solutions lack the interoperability and security needed to verify data authenticity, maintain digital perimeters, and ensure compliance with cross-border regulations.

Cross-Industry Interoperability Requirements

  • Zero Trust Authentication: Cross-industry interoperability requires claims and identities to be verified for each transaction to ensure maximum security. Read the Federal Zero Trust Strategy

  • Infosec & Selective Disclosure: Participants must be able to selectively disclose information for transactions at the edge. Verification must be done at the moment of transaction to eliminate the need for PII storage.

  • Scalability and Extensibility: Cross-industry interoperability requires a shared standards-based framework to enable the creation of globally scalable multiparty applications.

  • Data Privacy Compliance: Cross-industry interoperability requires (1) compliance with existing global data privacy regulations and (2) the flexibility needed to comply with future directives.

  • Global Standards: Cross-industry interoperability requires a standardized system for frictionless data exchange and collaboration while allowing stakeholders to retain their legacy systems.

  • Decentralization: Cross-industry interoperability requires a community-owned and -operated infrastructure to (1) prevent monopolization and (2) enable consensus-based trust.

Our Innovative Solution

Our Innovative Solution

Since it is not possible to enable cross-industry interoperability and business automation through Web2 means at scale, we must instead leverage Web3 technologies and principles to build a new solution rooted in trusted identity standards — one that facilitates seamless, privacy-preserving, globally compliant collaboration and data exchange while allowing stakeholders to retain their legacy systems.

The solution? Self-Sovereign Digital Twins™ (SSDTs™) — portable digital twins that can automatically authenticate identity and selectively disclose pertinent data for Web3 transactions at the edge. SSDTs™ combine standards from W3C, MOBI, IEEE, ISO, SAE, and others with Zero-Knowledge cryptography to offer the data privacy and autonomy needed to engage in secure, tamper-evident transactions across the connected ecosystem.

  • Enable seamless verification and validation of identities and transactions
  • Empower the creation of regulation-compliant data privacy solutions

  • Offer the ability to obtain and monetize connected data at the moment of transaction without the need to store data

  • Serve as platform-agnostic, legacy system compatible “universal translators,” eliminating the need to build new infrastructure / APIs

MOBI’s Decentralized Web3 Infrastructure

MOBI’s Web3 Infrastructure, designed to facilitate tamper-evident, privacy-preserving transactions between SSDT™ holders, consists of two member-owned and -operated layers: Citopia and the Integrated Trust Network (ITN).

Whereas most Web3 solutions combine identity verification and transactions processing, we choose to separate them into two distinct organizations, each with its own legal structure, governance, network, and operators. This increases decentralization and enhances data privacy by reducing the market power and information advantage of any single organization. The separation permits Citopia to use any W3C-compliant Decentralized Identifiers (DIDs) registry network, meaning Citopia users aren’t locked to the ITN (and vice versa).

  • The Integrated Trust Network (ITN) is a global, cross-industry W3C Decentralized Identifiers (DIDs) registry. Protocol, cloud, and technology agnostic trust anchor for digital identity management. Learn more about the ITN

Citopia and ITN were launched out of the MOBI consortium after the first pilot on MOBI Vehicle Identity (VID) in 2019 with BMW, Ford, GM, Groupe Renault, Honda, and VW. Members did not have networks like the ITN (to register DIDs for MOBI VIDs) or Citopia (for cross-industry interoperability & VCs issuance).

Per MOBI members’ decision, to prevent technology and vendor lock-in, both ITN and Citopia are federated networks (member-owned and operated). If MOBI, or any members, stops operating their node(s), the networks will continue to operate. Members are not required to use Citopia and ITN. However, if no members choose to use the infrastructure, then Citopia and ITN cease to exist. Both Citopia and ITN were incorporated outside of MOBI as for-profit entities to:

  • decentralize infrastructure-ownership
  • raise capital needed for R&D beyond what can be done with member dues
  • provide the infrastructure for members to build enterprise-scale, customer-facing applications
  • invite other consortia to join in on the efforts
  • Ease of Deploying Applications on Citopia & ITN: Node operators gain first-mover advantage in building scalable, privacy-preserving Web3 applications on top of Citopia while leveraging the ITN as a trust anchor for identity. Through active participation in the Citopia and ITN networks, organizations of all types can establish leadership in cross-industry interoperability and business automation.

  • Unlock New Streamlined Business Models: Node operators have the opportunity to accrue new net revenue through the creation of more efficient, privacy-preserving, and globally compliant business models based on distributed, trusted data — all while retaining their legacy systems.

  • Access to Cross-Industry Interoperability & Business Automation Ecosystem: Node operators gain access to an interoperable, Zero Trust ecosystem of applications for secure communication and collaboration on multiparty business processes. This offers unprecedented access to new customer bases and enables the formation of cross-industry partnerships without the need for costly one-off integrations.

  • Participate in Community Governance: The community-owned and -operated infrastructure of Citopia and the ITN helps to prevent centralized monopolies and build network resilience by ensuring that there is no single point of failure. By running nodes on Citopia and the ITN, MOBI members are empowered to play a significant role in decision-making, contributing their insights to shape the networks’ future direction.

  • Low Barrier to Entry: Operating a node is relatively inexpensive and does not require significant technical resources, meaning organizations of all sizes can easily get started deploying applications on top of Citopia. By facilitating easy entry, the Citopia and ITN networks promote inclusivity and democratize access to cutting-edge decentralized identity solutions. The elimination of complex integrations and reduced cybersecurity costs further paves the way for newcomers worldwide to engage with markets, fostering innovation and growth across industries.

Recommended Skill Set for Developing & Using Citopia and ITN

  • Languages: TypeScript, JavaScript/NodeJS, Go
  • DevOps: REST APIs, Docker, Kubernetes, Kafka, Cloud Platforms (e.g. AWS, Azure, Google Cloud, Digital Ocean)
    • Note: ITN deployment scripts are available in AWS & Azure (more to come)
  • Not required but familiarity would be ideal: PostgreSQL, Redis, CouchDB, IPFS, libp2p, DIDComm 2.X, W3C DIDs and W3C VCs
  • Note: Familiarity with blockchain development is not required to run a node on Citopia or the ITN.

Blockchain is often hailed as a “trust machine,” capable of replacing various trust-related services offered by traditional entities like banks, escrows, and digital platforms. While blockchain can accommodate a wide range of data, it’s crucial to exercise caution in deciding what goes on-chain. Namely, sensitive personal and business information should remain off-chain.

Blockchains are not efficient databases due to the significant overhead they introduce. Therefore, the use of blockchain-based trust solutions should be deliberate and well-considered. To make this determination, one must grasp the limitations of Web2 technology, centralized data solutions, and the benefits blockchain brings to the table.

By combining SSDTs with W3C DIDs anchored in blockchains (multiple chains therefore not to be locked into one) and VCs within federated networks, we can harness the strengths of both approaches. This entails achieving tamper-evident, redundancy, and transparency, enhancing data privacy and security (by pushing data to the edge for transactions instead of connecting to centralized databases), and combining the fraud resistance of public blockchains with the speed, efficiency, and cost-effectiveness of cloud data storage.

How Citopia and ITN Preserve Data Privacy

How Citopia and ITN Preserve Data Privacy

Digital identity comprises a combination of an entity’s identifiers — ex. an individual’s email address, a vehicle’s VIN — and the information associated with those identifiers. Today, digital transactions rely on identifiers issued by centralized platforms to authenticate themselves. However, in addition to being vulnerable to fraud, identity theft, and data leaks, centralized approaches to identity management lack the portability and flexibility needed to give entities adequate control over their digital identities.

Citopia and the ITN leverage W3C self-sovereign identity standards to form a collaborative framework between two independent networks — with neither containing complete information about any users or transactions — wherein participants can selectively disclose information for transactions at the edge.

Preventing Data Correlation

Preventing Data Correlation

To prevent data correlation, transactions are processed as W3C Verifiable Credentials (VCs) on Citopia, while participants’ identifiers — W3C Decentralized Identifiers (DIDs) — are anchored and verified on the ITN. An entity may create multiple DIDs for separate functions to further reduce the risk of data correlation. DIDs are the only things registered and stored on chains — all personal and competitive information is stored locally in the SSDT™ and remains under the control of the owner.
