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.

This article is showing how to implement the digital product passport (DPP) with some standards mentioned in the StandICT.eu

Our energy transmission and distribution grids are the backbone of modern society, and their protection from malicious actors is of paramount importance. This article dives into the various aspects of securing the data and controlling signal processing in the energy grid, examining the significance of provenance in grid assets, grid asset algorithms, and the data they generate.

In this blog post, we will explore the challenges, importance, and solutions for establishing authentic e-fuels in the renewable energy supply chain.

The Drug Supply Chain Security Act (DSCSA) defines the criteria for a pharmaceutical supply chain actor to be considered duly authorized, i.e. to be considered an ATP in the eye of the law. Before exchanging any potentially sensitive information as happens in certain product inquiries, so-called Product Identifier (PI) Verifications, trading partners are supposed to make sure they are dealing with an ATP at the other end.

It's a good time to reflect on the wide variety of non-human identities and how their specific needs can be critically important to business, society, and the future of our economy.

Check out Chris' piece in Pharmaceutical Commerce’s June issue, where she shares how OCI’s work on credential standards is enabling interoperable DSCSA solutions across the pharma supply chain.

To make circular economy models economically viable, especially for low-value transactions like recycling or refurbishment, we need persistent, verifiable data on every product's lifecycle. This article outlines Spherity’s vision for a “Circular Cloud” — an open, accessible system that enables data traceability and supports enforcement of circular regulations while unlocking new business models through decentralized cooperation.

In our new series Identity in a Circular Future, we explore how decentralized identity can drive the shift to a circular economy by enabling transparency, agility, and new models of open data and governance across IT and global markets.

In this #SSI101 glossary entry, we unpack Verifiable Credentials—secure, self-contained data capsules that bundle information with identity and context, making them portable, trustworthy, and ready for encryption, verification, and access control across digital systems.

In the third installment of the Meta-platform series, we move from theory to application—examining how trust-based, decentralized identity systems can reshape the economics of real-world industries. Drawing from Spherity’s own client work and research, this piece explores how cooperative infrastructure and verifiable trust can generate cost savings and unlock new business models across sectors.

This follow-up to the first whitepaper in the Meta-platform series continues to rethink traditional IT power dynamics by examining how trust operates in cooperative digital ecosystems. Building on a critique of Metcalfe’s Law and zero-sum platform models, it explores the role of decentralized identity and shared infrastructure in enabling sustainable, trust-based meta-platforms beyond the limits of aggregation.

In this crash course, we break down how decentralized identifiers (DIDs) and verifiable credentials (VCs) secure data and preserve privacy by design—without needing to be a math expert—so you can assess the tech yourself and understand its real-world value.

This condensed version of a whitepaper from the Rebooting the Web of Trust conference challenges the dominance of centralized platforms in IT valuation and strategy. Written collaboratively by leading thinkers in decentralized identity, it explores how decentralized systems—built as meta-platforms—can foster more cooperative, resilient, and future-proof business models than the closed ecosystems that dominate today.

We can turn to how blockchains differ for DID-anchoring purposes, and to how the blockchain-agnostic, interoperable W3C standard organizes them all to work together.

The evolution of retail is also the evolution of identity—this article traces how today’s global supply chains rely on complex serial number systems, explores longstanding challenges like leakage and binding, and shows how decentralized identifiers (DIDs) and digital twins can power the next generation of intelligent, self-verifiable product identities for circular, on-demand commerce.

Identity systems can be very abstract, heady things to grasp intuitively. One good trick for making glossaries more concrete and human-scaled is to avoid defining nouns and put the emphasis on verbs: who does what, and how, in each system?

In this post, we unpack the often-misunderstood concept of “sovereignty” in self-sovereign identity (SSI), clarify how it differs from related terms, and explain why it matters for both human and non-human identities in Spherity’s approach to digital trust.
