Digital identity (DID) has been a perennial weak link in Web3. Password‑less log‑ins, privacy‑by‑design, and strict compliance frameworks (GDPR, MiCA) have each begun to be solved in isolation, but never together. The idOS and Partisia partnership changes that.
idOS is a chain-agnostic, user-controlled decentralized identity system; Partisia Blockchain supplies a production‑hardened MPC layer that shards and safeguards every private key.
The result is the first fully open, zero‑custody identity stack able to scale from indie dApps to enterprise‑grade deployments.
Thanks to Partisia’s key abstraction, users can manage their idOS data securely without having to download new identity wallet software or remember a password; a simple signature with their wallet of choice will suffice. Partisia will be implemented as a native module within the idOS Storage Network, the L1 blockchain at the heart of idOS. Partisia struck the right balance of security, flexibility, and cost-effectiveness compared to other TSS-MPC providers, and we benefit from their collective decades of cryptography research and implementation leadership.”
Ben Basche, idOS CPO
Millions of wallets, hundreds of blockchains, and still the same awkward dance: copy a seed phrase, re‑upload documents, hope nothing gets lost. Web3 has delivered on transparency but fallen short on reusable privacy‑preserving identity. Every attempt so far has had to juggle three goals that rarely align:
Most solutions pick two and leave a gap. idOS covers usability and compliance, but securing the underlying keys, without adding a central custodian, remained unsolved. That is where Partisia’s fifteen‑year battle‑tested Multi‑Party Computation (MPC) fits in.
idOS is backed and governed by the idOS Consortium, including leading web3 projects like NEAR, Ripple, Arbitrum, and Circle, and serves as the identity layer for apps across multiple chains. Its modular SDK enables developers to integrate reusable, verifiable credentials, streamlining data access management for apps.
Users control their data by granting access via wallet signatures. Credentials are encrypted, reusable, and shared across apps with minimal friction.
Partisia Blockchain brings a production‑grade MPC engine. In practice, it slices every private key into cryptographic shards and distributes them across independent validator nodes. No shard, on its own or in any minority coalition, reveals anything useful. The key is only re-assembled in memory for milliseconds, under quorum, and never lives in a single place.
The net result is the first identity network where:
Traditional custody stores an encrypted key on a server. Lose the server, lose the key.
MPC treats the key like a jigsaw puzzle:
Because Partisia designed its public blockchain around MPC from day one, latency stays low enough for real‑time authentication, a critical point for consumer dApps.
Early pilots with consortium members will stress‑test the stack this summer; public onboarding is slated for Q4 2025.
Once the heavy cryptography is in place, new primitives become trivial, particularly with developments like GODS Network:
Each layer compounds the previous one, nudging web3 closer to a world where identity is flexible and composable, not captive or confined to any single ecosystem
Closed beta with consortium dApps is expected in Q3 2025. This will be followed by the release of the public SDK and docs in Q4 2025 as the early pilots begin stress testing the solution.
For years, decentralised identity talked about self‑sovereignty while leaning on centralised key stores or fragile seed phrases. By merging idOS’s user‑friendly credential system with Partisia’s production‑proven MPC, the partnership turns that rhetoric into concrete infrastructure—one that developers can call with a few lines of code, and that users never need to think about.
If the launch delivers on its roadmap, the bigger win isn’t just safer logins; it’s laying a cryptographic foundation sturdy enough to let identity and privacy finally scale together.
idOS is a decentralized, chain-agnostic identity layer designed to give users control over their data. It allows individuals to create, own, and manage verifiable credentials that can be reused across blockchains and dApps. With privacy and security as core principles, idOS ensures sensitive information stays encrypted and in the user’s control. Developers and enterprises can access compliant identity solutions while minimizing friction and simplifying integration with their modular SDK.
Partisia Blockchain is an innovative data ownership and privacy-preserving layer-1 blockchain built for real-world utility. Combining zero-knowledge proofs and secure multi-party computation (MPC), it empowers developers and enterprises to build decentralized applications with data privacy at the core. From RWAs and digital identity to supply chain and AI, Partisia is driving the next generation of blockchain use cases across web2 and web3 industries.

Pioneering a New Era of Trusted, User-Centric Digital Identity
Tokyo, April 2025 – In a world where identity is the gateway to education, work, and daily life, the need for secure, user-controlled, and globally trusted solutions has never been greater. This is magnified by a world that is becoming increasingly more connected and digital. Today, TOPPAN Edge and Partisia announce a groundbreaking partnership and proof-of-concept at the Okinawa Institute of Science and Technology (OIST), aiming to redefine how digital identity works for students. This solution is a bedrock for digital identity, with applications that can span industries and use cases.
This collaboration is more than a technical integration. It’s a shared vision to bridge the familiar convenience of web2 with the trust, privacy, and interoperability of web3. By combining TOPPAN Edge’s 100+ years’ experience, including a 33% market share in Japanese ID systems, with Partisia’s advanced cryptography and blockchain solutions, the partnership is setting a new standard for privacy-first, decentralized, digital identity (DID).
Japan alone has over 813 universities, 360 of which issue IDs with IC chips (FeliCa). This involves a process that is costly, slow, and increasingly vulnerable to impersonation and fraud. Meanwhile, students already carry NFC-enabled smartphones and are accustomed to seamless, app-based, digital experiences. The challenge is to deliver a digital identity solution that is as easy to use as a tap on your phone, but as secure and private as the most advanced cryptography can provide.
At the same time, global standards are rising. The EU’s eIDAS 2.0 and Japan’s Trusted Web initiative demand solutions that are not only secure and user-centric but also interoperable across borders and compliant with the latest privacy regulations. The answer lies in a hybrid approach: leveraging the best of web2 user experience and web3’s decentralized trust infrastructure.
The OIST pilot brings together the strengths of both partners in a layered, future-proof architecture:
This hybrid model ensures that universities can adopt the system with minimal disruption, while students benefit from privacy, security, and convenience.
A key innovation of this project is the clear division of roles between Partisia Infrastructure (PI) and Partisia Blockchain (PBC):
This architecture not only future-proofs the solution but also positions it for mass adoption, both in Japan and globally.
From June to September 2025, the pilot at OIST will involve up to 50 participants from the incubator facility. While the immediate focus is on access control within a university setting, the broader goal is to lay the groundwork for a scalable, privacy-first digital identity infrastructure.
This proof of concept begins with private issuance and verification to ensure the system functions seamlessly in a controlled environment. It then progresses to integration with Partisia’s public blockchain, the release of a public-facing wallet, and the deployment of an on-chain credential registry.
Crucially, this pilot is not the end state. It’s a critical foundation. The architecture being tested is designed to evolve beyond student IDs and campus access, opening the door to applications in IoT, payment infrastructure, and digital identity systems for employers, healthcare, and beyond. By anchoring this work to the Partisia blockchain, this collaboration supports the long-term goals of Japan’s Trusted Web initiative, offering a decentralized, interoperable solution where user control and privacy are built in from the start.
Key performance indicators include sub-second check-in times, zero false-accepts, and full compliance with GDPR and eIDAS audit requirements. The success of the pilot will be a critical first step in building the next generation of secure, user-centric identity systems.
The potential of this platform extends far beyond student IDs. Future applications include:
By anchoring these use cases on a public blockchain, the solution ensures interoperability, transparency, and long-term trust.
As the ecosystem grows, the Partisia blockchain will play an increasingly vital role in securing and governing digital identities. While the initial focus is on establishing a robust and user-friendly platform, future iterations may include:
These features will not only enhance the utility of Partisia blockchain but also create new opportunities for innovation and value creation.
“By fusing TOPPAN’s proven access-control hardware with Partisia’s privacy tech, we’re making the jump from Web2 convenience to Web3 trust, and setting a new global benchmark.”
Mark Medum Bundgaard, Chief Product Officer, Partisia
“This collaboration lays the foundation for a new data economy where confidential student data can finally be activated without ever being exposed.”
Kurt Nielsen, CEO & Co-founder, Partisia Blockchain
“Japan is embracing blockchain to make identity both secure and user-centric. With Partisia, privacy is built-in from day one.”
Masatoshi Oka, General Manager, ID Business Management Division, TOPPAN Edge
Building on the outcomes of the OIST pilot, the roadmap for this collaboration intends on exploring:
