PIC in action

Authority is continuity, not possession. See it live, three ways: step through the protocol flows wire by wire, watch the use cases where continuity goes to work, or follow a decentralized subchain as it returns to PIC-X for a checkpoint. Everything is interactive — the flows evaluate their checks from the displayed Profile 0.2 structures, the use cases are illustrative walkthroughs — and every scenario has its own link.

01 · the protocol

Flows

An OAuth token exchanged into a PIC execution, continuity advanced hop by hop, and the invalid state that can never validate. Every artifact inspectable: PIC Token JWT, PIC Continuity COSE, PIC Continuity Transition COSE — checks are evaluated from the displayed structures; byte strings, hashes, challenges, and signatures are illustrative.

Use Cases

A service mesh that exchanges OAuth at the edge — zero application changes — then gets one of its services compromised. An AI agent that can propose anything, gets prompt-injected, and still can only cause what the origin authorized. And agents calling agents through a guardrail that cannot be skipped. Run them, break them, watch what the attacker actually gets.

Subchains

A wallet or PIC-X-compliant IdP creates authority; PIC-X propagates it into continuity. A bounded subchain then travels through moving swarms of autonomous AI agents, returns for compact checkpoints, and remains governed by the source plus PIC-X policy.

jump to subchain and checkpoint

Both paths run on the same substrate: PIC Profile 0.2 (the Designing PIC-X series) — RFC 8693 Token Exchange at the realm token endpoint, realm-signed checkpoints, workload-signed candidates, sd-jwt Proof of Relationship, and non-expansive attenuation. Every scenario has its own URL, so you can link straight to a flow, a use case, or a decentralization walkthrough. More demos will land here over time.
