By implementing strict access controls and continuous authentication of all entities entering the network for all transactions, zero trust minimizes the potential for data breaches, provides greater visibility into network traffic and activities, and strengthens regulatory compliance.

MOBI’s Decentralized Web3 Infrastructure

Citopia and the Integrated Trust Network (ITN) form MOBI’s Web3 Infrastructure — a member-owned and -operated technology stack designed to facilitate tamper-evident, privacy-preserving transactions across the connected ecosystem. Both Citopia and the ITN are incorporated as separate and independent entities. MOBI membership is required to operate nodes on Citopia and/or the ITN. Learn more about MOBI

  • Citopia is a decentralized marketplace built to enable seamless onboarding & management for identities and assets, application discovery, and trusted credential validation.

  • 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.

  • 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 Full Stack Developer Using Citopia and the 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.

1 Node = 1 Vote

Citopia’s infrastructure, collectively owned and operated by the community, is designed to combat the emergence of centralized monopolies and bolster network resilience by eliminating single points of failure. Our approach to governance is straightforward, democratic, and decentralized: In this system, every node counts as one vote, with each vote carrying equal weight.

Through running nodes on Citopia and the ITN, members are empowered to wield substantial influence in decision-making processes. They can actively contribute their valuable insights, thus shaping the future direction of these networks.

Significant progress has been made recently in the acceptance and exploration of DIDs (Decentralized Identifiers) and VCs (Verifiable Credentials) by stakeholders across public and private sectors, with numerous government bodies worldwide actively involved. Presented below are several examples of initiatives aimed at harnessing the potential of DIDs and VCs:

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.
