In this article, we walk through a real-world Digital Product Passport (DPP) showcase using decentralized identifiers (DIDs) and verifiable credentials to demonstrate how open, permissionless standards can power trusted, interoperable product data—from a running T-shirt to batteries—aligning with EU regulations and enabling secure, lifecycle-wide transparency without vendor lock-in.

In our increasingly digitised and sustainability-oriented world, digital organisational identities are gaining importance, especially in the context of the financial industry. These identities allow companies to securely and efficiently share verifiable information about their business practices, including KYC and ESG (environmental, social, governance) metrics, with financial institutions.

In this article, we show the first working Battery Passport whose authenticity can be proven and that links to verifiable supply chain data, such as a third party Due Diligence report. Battery Passports must be attached to each battery that is placed on the European Market starting from August 2025 with CO2 data of the battery.

In the rapidly evolving digital landscape, the concept of identity is undergoing a significant transformation. The traditional centralized models of identity management, where a single authority verifies and manages identities, are increasingly being challenged by decentralized identity technology.

RCS Global partners with Spherity to enhance battery supply chain sustainability with decentralized identity and data sovereignty.
