Decentralized Code Signing for Open Source Software
C6/10April 8, 2026
WhatA certificate authority and code signing infrastructure for open source developers that cannot be unilaterally revoked by any single platform vendor.
SignalDevelopers are deeply frustrated that Microsoft and Apple act as gatekeepers who can arbitrarily revoke code signing certificates, effectively killing distribution of legitimate open source software with no recourse or explanation, and the current system provides no real security benefit since leaked certificates are widely available to bad actors anyway.
Why NowHigh-profile revocations of certificates for established projects like VeraCrypt and LibreOffice are accelerating distrust, while Let's Encrypt has already proven the model of free, automated certificate issuance at scale, and regulatory attention on platform gatekeeping (EU DMA) creates a policy tailwind.
MarketMillions of open source developers and small software publishers who need code signing; enterprises paying $200-500/year per certificate; TAM roughly $500M+ across code signing and software supply chain security; competitors are legacy CAs like DigiCert and Sectigo who are expensive and opaque.
MoatNetwork effects from a trust store that OS vendors and users adopt — once established as the default verification layer, switching costs are enormous, similar to how Let's Encrypt became the de facto TLS issuer.
AI-Powered Codebase Intelligence Dashboard for New DevelopersP6/10A tool that automatically analyzes any git repository and generates an interactive onboarding report — hotspot files, key contributors, bug-prone areas, project velocity — so new team members understand the codebase before reading a single line of code.
Git Repository Health Monitor with Continuous AlertsC6/10A lightweight service that continuously monitors git repositories for code health signals — rising churn in specific files, firefighting frequency, declining commit velocity, author concentration risk — and sends proactive alerts to engineering leaders.
Native Mac Frontend for Ghidra Reverse EngineeringC5/10A native macOS (AppKit + SwiftUI) frontend shell for the Ghidra reverse engineering framework, replacing its Java-based UI while keeping the powerful analysis backend.
Developer Escalation Platform for Big Tech SupportC5/10A service that helps developers and open source projects escalate blocked accounts, revoked certificates, and other platform disputes with big tech companies through media pressure, legal templates, and insider connections.
Privacy-First Community Safety Camera PlatformP7/10A municipal surveillance camera system that processes footage on-device with no cloud upload, no license plate tracking network, and full local government data control.
Automated Public Surveillance Infrastructure Transparency ToolC5/10A civic tech platform that maps, identifies, and tracks every surveillance device installed in public spaces — who owns it, what data it collects, what policies govern it, and whether proper approval was obtained.
