From autonomous drones to on‑device personal assistants, the need to run inference locally—without round‑tripping to a remote cloud—has never been stronger. Historically, the computational demands of large language models (LLMs) forced developers to rely on cloud‑hosted APIs such as OpenAI’s ChatGPT or Google’s PaLM. Those services offered impressive capabilities but introduced latency, bandwidth costs, and data‑privacy concerns. ...

Introduction Artificial intelligence has long been dominated by centralized cloud services. Large language models, computer‑vision pipelines, and recommendation engines typically run on powerful data‑center GPUs, while end‑users simply send requests and receive predictions. This architecture brings latency, privacy, and bandwidth challenges—especially for applications that need instantaneous responses or operate in offline environments. Enter decentralized AI: a paradigm where inference happens locally, on the device that captures the data, and where multiple devices can collaborate to share compute resources. The WebGPU‑P2P standards, released in early 2025, extend the WebGPU API with peer‑to‑peer (P2P) primitives that make it possible for browsers, native apps, and edge devices to exchange GPU buffers directly without routing through a server. ...

Introduction As quantum computing advances, traditional encryption standards like RSA and ECC face existential threats from algorithms such as Shor’s, capable of breaking them efficiently.[2] Post-quantum cryptography (PQC) standards, finalized by NIST in 2024 including CRYSTALS-Kyber for key establishment and CRYSTALS-Dilithium for digital signatures, provide quantum-resistant alternatives based on lattice-based, code-based, and hash-based mathematics.[1][2][3] In distributed edge computing networks—where IoT devices, sensors, and gateways process data locally—optimizing local inference for these PQC algorithms is critical to maintain low-latency security without overburdening resource-constrained hardware.[2] ...
