# pic-pca
PCA (Provenance Causal Authority) and PoC (Proof of Continuity) types for the PIC Protocol.
**Status:** Experimental
---
## About
This crate is part of the reference implementation of the PIC Protocol as defined in the [PIC Specification](https://github.com/pic-protocol/pic-spec).
The **PIC Model** is original theoretical work created by **Nicola Gallo**.
This implementation is developed and maintained by **Nitro Agility S.r.l.**
---
## Overview
This crate provides the core data structures for the PIC Protocol:
- **PCA (Provenance Causal Authority)**: The causally derived authority available to an Executor at each hop
- **PoC (Proof of Continuity)**: Non-forgeable proof demonstrating valid causal continuation
