## TL;DR
Decentralized AI: Distributed Inference, Peer-to-Peer Networks, and Blockchain Integration: Decentralized AI distributes training, inference, data control, or governance across devices, organizations, or peer networks.

## Core Explanation
The most evidence-backed public framing is federated and privacy-preserving machine learning. Decentralization can reduce raw data movement, but it introduces coordination, security, privacy, and verification challenges.
