Security

On April 20–21, 2026, the 4th International Workshop on Trends in Digital Identity (TDI 2026) takes place in Verona. The workshop program also includes the talk “Provenance Identity Continuity (PIC): Secure Authority Propagation from Human and Non-Human Origins Across Trust Boundaries”, presented by Nicola Gallo and Antonio Radesca (Nitro Agility Srl).

On March 3, 2026, LF Decentralized Trust hosted the session “From Identity-First to Authority Continuity”, presented by Nicola Gallo.

On March 3, 2026, LF Decentralized Trust hosted the session “Trusted AI Agents by Design: From Trust Ecosystems to Authority Continuity”, presented by Nicola Gallo.

Over the past couple of years I have written several articles touching on ZTAuth* and PIC. Reading them today, some point in different directions, different angles, different emphasis, different terminology. That is a natural part of how a model evolves when you are building and thinking at the same time.

Ambient Mesh is redefining the Cloud Native service mesh for Zero Trust, whilst ZTAuth* completes it with Trust Chains built on Trust Elevation, Trust Levels, and cryptographic signatures. This article explores how these concepts apply to microsegmented and asynchronous workloads.

Single-merchant payments are easy; real commerce is not. The moment users ask an AI agent to buy multiple items from different merchants at the best available prices — and expect all-or-nothing consistency — the problem shifts from a single transaction to multi-merchant coordination. And that’s where today’s token-based models break down.

AI agents bring new security challenges, but also an opportunity to rethink traditional models.
By looking at payments from a decentralized perspective, we can explore privacy-oriented solutions.
