Web applications are only as trustworthy as the servers that serve them, and servers can get hacked. So, last year, we introduced WEBCAT (Web-Based Code Assurance and Transparency), a project designed to enable verifiable in-browser code for web applications. We wrote extensively about WEBCAT’s requirements, constraints, and goals.Today, we’re excited to announce the alpha release of WEBCAT. In particular, we invite community participation in a new, decentralized enrollment infrastructure.
Introducing WEBCAT: Web-based Code Assurance and Transparency
In this post, we introduce Web-based Code Assurance and Transparency, a project that supports verifiable in-browser code for single-page browser applications. Along with this post, we are publishing the WEBCAT project repository; follow-up posts will provide more detailed information.
WEBCAT - Verifiable Code for the Web
WEBCAT helps people trust the websites they use by making it possible to verify the code running in their browser.
Kicking off our alpha program
In March, we shipped a stable version of Web Applets, a protocol that extends the web to make it possible for agents and websites to communicate, with just a few lines of JavaScript.

On forking the Web
This document contains a set of informal notes on how to build an alternative specification to the Web, in such a way that hopefully prevents many of its drawbacks while still preserves many of the good points. This document is not an specification, and is therefore subject to change over time.

Web publishing is facing its next challenge: a new iteration of centralizing platforms. BUT there is also a new wave of open protocols and standards that can help us gain our independence. Next month in NYC we are gathering a group of frontier technologists and popular web publishers to discuss how we can sail into this next platform shift as captains. #ProtocolsForPublishers https://pfp.unternet.co
