MOBI Members Lead the Way for Web3 Digital Product Passports and Data Spaces Interoperability

Phase I of the Global Battery Passport System Demonstrated Product Traceability with Privacy-Preserving Capabilities and Selective Data Disclosure

LOS ANGELES, March 31, 2025 /PRNewswire/ -- MOBI, a nonprofit Web3 consortium of global industry leaders, announces the successful completion of the first year in its three-year initiative to build the Global Battery Passport System (GBPS). This milestone marks a significant step in creating a secure, Self-Sovereign Identity and Data framework for seamless data spaces interoperability and digital product passports. MOBI is actively demonstrating data spaces interoperability with other global consortia such as Gaia-X. While the GBPS initiative focuses on battery data exchange as its use case, the underlying technology is agnostic and can be leveraged to enhance trust, compliance, and operational efficiency for all digital transactions and traceability. 

MOBI GBPS initiative is being spearheaded by members of the Circular Economy and the Global Battery Passport (CE-GBP) Working Group, including Anritsu, DENSO, HIOKI, Honda, Mazda, Nissan, Orico, Suzuki, and TradeLog.

During Phase I, which took place from January to December 2024, working group members concentrated on evaluating global battery regulatory requirements and developing use cases aligned with Web3 technology for secure data exchange and management. Critically, implementers successfully launched and ran nodes on the federated Integrated Trust Network (ITN), a member-built and operated registry for World Wide Web Consortium (W3C) Decentralized Identifiers (DIDs). The ITN provides the core trust services of governance, authority, identity, and assurance to enable verifiable transactions between Self-Sovereign Digital Twins (user agents) whose DIDs are anchored in the ITN.

Building on the success of Phase I, MOBI and its partners are now advancing to Phase II. In Phase II, implementers will leverage ITN core services to test transactions within the Citopia Decentralized Marketplace (DM). Anticipated technical achievements in Phase II include Web3 ecosystem onboarding, asset ownership traceability, secure data exchange, and Apps building with Citopia DM. 

The GBPS shall operate as a specialized user-controlled application within Citopia DM, which supports secure communication, transactions, and data sharing across industries with zero-knowledge proofs. Citopia DM provides the interoperability and data sovereignty that Web3 ecosystems and value chains require. Through this setup, the GBPS shall offer a privacy-focused solution that protects proprietary information and promotes circularity in line with current and future regulations, while serving as a robust foundation for use-case-specific applications rooted in trusted and verifiable battery data, such as:

• management of battery passports,
• used electric vehicle (EV) pricing,
• green financing and carbon credits,
• charging management, and more.

While most battery passport solutions focus on public data disclosure, Citopia GBPS emphasizes secure sharing of proprietary data. The GBPS leverages zero trust architecture and selective data disclosure, where only relevant information is shared with intended recipients. This privacy-centric design facilitates regulatory compliance while safeguarding sensitive data, reducing the need for intermediaries and enhancing trust across value chains, creating a Web3 system for data spaces interoperability across borders and stakeholders.

"As current and future regulations develop, solutions like the ITN and Citopia DM are essential for addressing industry and regulatory needs. MOBI is proud to work with our members in developing a solution that is agnostic to existing data spaces along with Web2<>Web3 interoperability to support business objectives in creating a more secure digital future and meeting circular economy goals," said Tram Vo, CEO and Co-founder of MOBI.

"A global battery passport system has the potential to unlock new levels of traceability, transparency and security in battery-related applications, supporting our efforts to contribute to greener and safer mobility," said Roger Berg, vice president of North America Research and Development at DENSO. "While that's an important goal for our team, this solution also represents more than that. It's a great example of how MOBI and our fellow members are working together to support a more circular economy and sustainable world."

"The second stage of Phase I has provided further valuable insights to CE-GBP WG partners. In Stage 1, the basic data sharing environment was established. In Stage 2, the first business-related technical capabilities were explored, such as the ownership management of a DID-based asset and the selective disclosure of data between two organizations," said Christian Köbel of Honda. "These successful learnings have encouraged us to further explore the potential of a self-sovereign data ecosystem to address future challenges of the circular economy."

"The functionality of DIDs and Verifiable Credentials for reliable data federation among implementing companies has been successfully verified, utilizing the Integrated Trust Network. This endeavor not only demonstrates the potential of these technologies to enhance data federation but also emphasizes the constructive and agile collaboration achieved among implementers within the cooperative framework." said Yusuke Zushi, Senior Manager at Nissan.

"In Phase 1 of the Global Battery Passport (GBP) system demonstration, we learned that the MOBI GBP can be used to exchange highly confidential information. We want to thank everyone involved in Phase 1," said implementers at Mazda Motor Corporation.

Said Hisashi Matsumoto of Anritsu, "MOBI's activities have led to the successful completion of Phase I, moving towards building an ecosystem that enables reliable and secure information exchange. We are grateful to have participated in the verification of use cases with practical operations. We hope that MOBI's efforts will continue to contribute to a more sustainable circular economy."

"We are very proud of the great results of Phase I which we have achieved based on our strong relationships with major OEMs, Tier 1 suppliers, and more. It has been an exciting and interesting experience to work with such talented people. We will continue to take on challenges in Phase II in the name of collaboration," said Alvin Ishiguro, Project Coordination at TradeLog, Inc.

MOBI and its members are committed to driving a future where collaborative, decentralized technologies foster innovation and transparency across industries.
