In the fast-evolving automotive industry, the convergence of technology and innovation is not just a trend but a necessity. At the forefront of this revolution is the Automotive Solution Center for Simulation (ASCS), a non-profit hub dedicated to research and innovation.

To improve the efficiency and reliability of membership management authentication, ASCS has led an innovative project, uniting forces with Altme, an open-source digital identity wallet, and Tezos, a leading smart contract platform.

This collaboration aims to empower the automotive ecosystem with secure and decentralized digital identities, transforming the way ASCS members and their employees access services, data spaces, and online platforms.

ASCS also plays a pivotal role in the Gaia-X 4 PLC-AAD consortium, a part of the Gaia-X future of mobility initiative. This consortium is dedicated to creating an open, distributed data ecosystem to revolutionize product development, manufacturing, and customer service in the automotive sector.

One of the goals is to use the verifiability of open Decentralized Identity (DID) standards and Verifiable Credentials (VC) to access these data spaces in a reliable way. Particularly in the simulation domain of highly automated and software-defined vehicles, deep and broad international supply chains pose major challenges for automotive manufacturers and suppliers. The solution lies in distributed data ecosystems based on the latest technologies that bring trust and a higher degree of automation to the development of new vehicle generations.

With the innovative DEMIM project (Decentralized Member Identity Management) the ASCS offer its members a trust anchor framework based on W3C Decentralized Identities. The ASCS issues as a trust anchor verifiable credentials (digital identities) for member companies. This also includes the current membership status. With this company credential it is possible for members to issue verifiable credentials for their employees directly or using ASCS site. These verifiable credentials can be used for the onboarding process across services, data spaces, websites and so on.

The Altme Wallet stands as a key player in this movement, offering a user-friendly and robust mobile wallet for managing decentralized identities and verifiable credentials.

Here is why the Automotive Solution Center for Simulation has choosen Altme :

2.1 Adherence to open standards, open-source code, and industry best practices

The Automotive Solution Center for Simulation (ASCS) has selected the Altme wallet for its initiative to enhance membership management authentication through decentralized identity technology due to its unwavering commitment to open standards, open-source code, and industry best practices.

These principles are at the core of Altme's development and operation, ensuring that the wallet is compatible and interoperable with a wide range of platforms and applications, adheres to the highest security standards, and is accessible to a broad user base. Also, Altme's adherence to open-source code grants developers unrestricted access to the wallet's source code, empowering them to contribute to its development. 

2.2 User-centric design

Altme's user-centric design prioritizes the ease of use and accessibility of the wallet for individuals with varying levels of technical expertise. The intuitive interface and user-friendly features streamline the management of digital identities and verifiable credentials, making it accessible to a wide audience, including those with limited technical knowledge.

2.3 Developer-friendly approach

Altme's commitment to open standards and open-source code extends to its developer-friendly approach. The new wallet's Developer Mode provides developers with the tools and resources they need to create and test SSI applications, leveraging Altme's capabilities and contributing to the development of advanced decentralized identity use cases.

In summary

Altme's adherence to open standards, open-source code, and industry best practices, coupled with its user-centric design and developer-friendly approach, makes it an ideal choice for ASCS's decentralized identity project, and a valuable tool for organizations seeking to create digital identities in the decentralized future.

3. Creating an immutable, censorship-resistant revocation registry with Tezos smart contract platform

In conjunction with Altme, ASCS leverages Tezos's blockchain technology to create an immutable, censorship-resistant revocation registry for verifiable credentials. Tezos is renowned for its robust features and suitability for decentralized identity applications.

Here is why the Automotive Solution Center for Simulation has choosen Tezos :

3.1 Institutional-grade security

Tezos is designed to provide the security demanded for high-value applications, ensuring the safety of both the protocol and application layers. Its use of OCaml and Michelson, languages that facilitate formal verification, a common practice in mission-critical industries, further reinforces its security credentials.

3.2 Energy efficiency

Tezos's Proof-of-Stake consensus mechanism consumes significantly less energy compared to Proof-of-Work blockchains, making it an environmentally friendly choice for decentralized identity applications. As the Web3 movement gains momentum, the need for sustainable blockchain infrastructure becomes increasingly crucial. Tezos's energy-efficient approach stands out in this regard.

3.3 Reliable smart contracts

Tezos is recognized for its advanced smart contract capabilities, enabling the creation of secure and reliable applications. Its smart contracts can be formally verified, ensuring that their code adheres to specific requirements and optimizes security.

3.4 Upgradeable and future-proof

Tezos stands out for its continuous upgradeability, a feature that sets it apart from other blockchain platforms.
