Many older web-based surveillance systems rely on this plugin to stream high-definition video feeds.
(notably older Samsung models) that rely on legacy native code to display live video feeds.
Statically analyzed the compiled code to ensure it did not exploit CPU vulnerabilities or execute unsafe memory instructions.

Traditionally, browsers relied on JavaScript to execute code. While JavaScript engine performance has improved drastically over the years, it historically struggled with heavy computational tasks like 3D video game rendering, video editing, and complex mathematical simulations.

| Date | Event | Significance | | :--- | :--- | :--- | | | Initial Development & Release | Google begins developing NaCl as a research project to safely run native code in a browser. Early versions were a downloadable NPAPI plugin. | | September 2011 | Chrome 14 | NaCL is integrated directly into Chrome, marking its shift from an experimental add-on to a built-in feature. | | 2013 | Introduction of PNaCl | Portable Native Client is launched, addressing portability issues and allowing apps to run on the open web. | | March 2015 | WebAssembly (Wasm) Announcement | A new, universal binary format for the web is announced as a collaborative effort between all major browser vendors (Google, Microsoft, Mozilla, Apple). | | May 2017 | Deprecation Announcement | Google officially announces the deprecation of PNaCl, signaling its intention to fully embrace the emerging WebAssembly standard. | | October 2020 | Chrome 88 | This release becomes the last version to fully support PNaCl and NaCl. | | May 2021 | Chrome 90 | Google Chrome completely removes support for both NaCl and PNaCl. Applications relying on these technologies stop functioning for Chrome users. | | December 2023 | Final Removal in Edge | Microsoft Edge version 120 removes all support for NaCl, marking the end of the technology's lifecycle across modern browsers. |
Major game engines, including Unity and Unreal Engine, used NaCl to port graphics-heavy desktop games directly to Chrome without loss of performance. Instructions on how to from your system
It used a "sandbox" to ensure that untrusted native code could not harm the user's operating system. Performance:
Complex rendering engines could process pixel data at maximum hardware speeds.
Before its introduction, heavy computational tasks—such as 3D gaming, video editing, and complex simulations—were mostly impossible using JavaScript, which was much slower at the time. Developers who wanted native performance were forced to rely on high-risk, third-party plugins like Adobe Flash, Microsoft Silverlight, or Java Applets.
The paper outlines how NaCl allows x86 native code to run directly on the processor but isolates it from the rest of the operating system. It achieves this through a two-step process:
Native Client aimed to bridge the gap between heavy-duty desktop applications and the lightweight web. By using a secure sandbox, it allowed developers to run complex logic—like video processing or 3D games—directly in Chrome without compromising user security.
