Identity in a Circular Future — Part 2/2
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.

#SSI101: Verified Credentials and Data Portability
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.

The Economic Value of Decentralized Identity — Part 3
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.

The Economic Value of Decentralized Identity — Part 2
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.

#SSI101: Encryption and Correlation
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.

The Economic Value of Decentralized Identity — Part 1
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.

#SSI101: What exactly does Spherity write to the blockchain?
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.

#SSI201: Upgrading products with intelligent serial numbers and DIDs
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.

#SSI101: Attest, Identify, Authenticate, and Verify
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?

#SSI101: Self-Sovereignty and Autonomy
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.

#SSI101: An Introductory Course on Self-Sovereign Identity
“Identity” is an important, hotly debated, and nearly undefinable core concept of human life. Outside of a few philosophers, social scientists, and a tiny minority of specialized technologists, however, most people feel uncomfortable making any definitive or authoritative statements about identity.

A Bright Future for the Decentralised Identity Business
The W3C’s recognition of the Decentralised Identifier Working Group marks a key milestone for digital identity. It signals the start of a new internet era—where trust, data control, and collaboration are built into the very foundation of digital infrastructure.
