Citopia

Citopia is a member-built and operated Web3 decentralized marketplace designed to facilitate interoperability between existing systems and data spaces for seamless and secure digital transactions.

Citopia is a member-owned and operated decentralized marketplace for cross-industry interoperability and business automation.

What is Citopia?

Citopia is a member-built and operated decentralized marketplace that transforms how organizations and individuals engage in secure digital transactions, enabling interoperable, privacy-preserving, and trusted data exchange across industries. Built on Self-Sovereign Data and Identity (SSI) principles, Citopia provides standardized communication protocols that serve as a shared language between data spaces, organizations, applications, and cloud environments.

In Citopia’s decentralized marketplace, every entity has a Self-Sovereign Digital Twin™ (SSDT™). Think of an SSDT™ as a secure digital lockbox containing pertinent World Wide Web Consortium (W3C) Decentralized Identifiers (DIDs) and Verifiable Credentials (VCs). With SSDTs™, any entity can autonomously manage its own digital identity, data, and transactions to interact securely within the decentralized marketplace.

Citopia is composed of a federated network of node operators, known as Citopia Members, who provide governance and core infrastructure for the ecosystem. These members and their partners can onboard applications and services onto Citopia, forming a Web3 marketplace for verifiable and secure transactions. Learn more on the Citopia website

Why Citopia?

Fragmented, siloed data spaces and systems make digital transactions costly, inefficient, and vulnerable to security risks. Citopia solves these challenges by providing a decentralized, privacy-first framework that enables seamless, direct collaboration and communication between organizations using SSDTs™ without the need for additional infrastructure. Citopia Decentralized Marketplace (DM) serves as the communication interoperability interface for entities and applications on Citopia, enabling secure, direct coordination and data exchange between participants. Citopia capabilities have been demonstrated through several completed and ongoing Web3 pilots.

Citopia DM serves as a middleware layer to enable fast, low-cost collaboration between data spaces and traditionally siloed organizations. By providing an interoperable and extensible framework, Citopia enhances efficiency, accountability, and value creation across extended value chains.

Users control their own data and share only necessary information for each transaction, ensuring compliance with GDPR, CPRA, and other global regulations.

Citopia eliminates costly one-off integrations by allowing seamless data exchange across platforms, systems, and cloud environments.

Citopia provides standardized protocols that enable existing Web2 applications to integrate with emerging Web3 technologies.

Citopia allows for data verification from multiple sources, allowing seamless tracking and management throughout a product’s lifecycle. This unified approach provides a holistic view without the limitations of siloed systems.

Citopia enables trusted, verifiable transactions, unlocking opportunities in digital identity, circular economy, supply chain tracking, and more.

How Citopia DM Works

Citopia Decentralized Marketplace (DM) serves as a user-controlled marketplace of applications, allowing businesses and individuals to securely exchange trusted information with shared communication protocols. Think of it like a decentralized version of Atlassian. Unlike in centralized marketplaces, users can selectively disclose information to share only what is necessary for a given transaction, and transaction records are retained in users’ SSDTs™ (not by Citopia or the apps).

Transactions with SSDTs™

When an entity (organization or individual) registers a new Citopia DM account, this automatically generates an SSDT™ tied to the account. The SSDT™ powers secure transactions and data exchanges, consisting of two components:

  • A Wallet that securely stores DIDs and cryptographic keys. DIDs are encrypted signatures for Web3 transactions.
  • An Encrypted Data Vault (EDV) that stores VCs and Verifiable Presentations (VPs) for transactions. VCs and VPs are Web3 transactions.

SSDTs™ are the key enabler for interoperability. Think of an SSDT™ as a secure digital passport, containing all of the relevant credentials and key management tools. The contents of a given SSDT™ are not accessible to any external entity, including Citopia Inc., without the SSDT™ owner’s express permission.

Company A, an electric vehicle manufacturer, must prove to a Conformity Assessment Body (CAB) that a battery — Battery A — is in compliance with EU Battery Regulation Article 77/Annex XIII/Section 1 requirements (see MOBI Battery Birth Certificate Technical Specifications standard). 

Here’s how this transaction unfolds in Citopia GBPS App:

  1. Both Company A and CAB sign up for Citopia DM accounts, which generate respective SSDTs™. Membership credentials are created for each company in the form of VCs and stored in their respective SSDTs™. 
  2. Both Company A and CAB use their Citopia membership credentials to create accounts in Citopia GBPS App.  
  3. Company A and CAB create a private communication channel within the Citopia GBPS App for Selective Disclosure (data only to intended recipient). 
  4. Both parties pre-settle on how often Company A must share battery information to ensure regulatory compliance. This is unique to each jurisdiction. 
  5. Company A sends a Verifiable Presentation (VP) to CAB with the required battery data (using MOBI Battery Birth Certificate Standardized Schema) as per the agreed-upon schedule. 
  6. CAB verifies the identity of Company A and checks the battery data to ensure regulatory compliance. 
  7. CAB sends a VC to Company A verifying that Company A has fulfilled the necessary requirements for the period.

Citopia DM facilitates countless interactions across industries, ensuring trustworthy, seamless, and privacy-preserving transactions. Whether verifying the provenance of materials, confirming digital asset authenticity, or ensuring regulatory compliance, Citopia empowers entities to securely exchange verified information without compromising data ownership. This innovative model creates a transparent, efficient, and resilient Web3 ecosystem.

Become a Node Operator

Citopia provides a flexible middleware layer to enable seamless and secure business interactions for both Web2 and Web3 data consumers alike.

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 existing systems.

Node operators gain access to an interoperable, Zero Trust ecosystem of applications for secure communication Node operators gain first-mover advantage in building scalable, privacy-preserving Web2/Web3 applications on top of Citopia 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.

The community-owned and -operated infrastructure of Citopia helps to prevent centralized monopolies and build network resilience by ensuring that there is no single point of failure. Node operators are empowered to play a significant role in decision-making, contributing their insights to shape the networks’ future direction.

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, Citopia promotes inclusivity and democratizes access to cutting-edge decentralized identity solutions.
