    Hi! I built Lockbridge because encrypted file sharing and management are still too complicated in 2025. Core features: - Bridges – shareable links for encrypted uploads/downloads with auto-expiration - Cloud federation – unified dashboard for S3, Azure, GCP, Google Drive, Dropbox and more… - Blockchain audit trails – immutable compliance logs on Polygon for HIPAA/SOX (optional) - Zero-knowledge encryption – client side end-to-end encryption, we can't decrypt your files Example use case: Create a bridge, send the link to a client, they upload files directly to your Google…

    Hi HN, We (myself, Adhyyan1252 and yush_g) are undergrad students that hacked out this side project last month during Hack Lodge[1] (the ideas and many of the underlying circuits for which came from the 0xPARC community[2])! We’re extremely excited to share this new primitive. Besides the technical challenges building this project that folks here would find interesting (fixing the ZK proof compiler, modifying nodeJS V8 params etc.), we think this is a very novel use case for ZK tech, and ECDSA inside ZK-SNARKs is a starting point that unlocks many other ideas! :D A summarized version of our…

    Hey HN! I want to share a project I've been working on, a Zero Trust Assessment Tool. It's designed to provide insights into your identity and device security framework. It incorporates data on user authentication and device management practices to generate a rating based on the CISA Zero Trust Maturity Model. Key Features: -Comprehensive analysis of identity and device-related factors -Recommendations for enhancing your security environment I'd love for you to give it a try and get some feedback. Thanks!

    Hey folks! We have just released NetBird. It is a big update so I decided to share it here and get your feedback :) NetBird creates an overlay peer-to-peer network connecting machines automatically regardless of their location (home, office, data center, container, cloud, or edge environments) unifying virtual private network management experience. It uses ICE protocol (WebRTC) to negotiate p2p connections and WireGuard (kernel module, when possible) to create a fast and encrypted tunnel between machines, falling back to relay (TURN) in case a p2p connection isn't possible. Pretty much just…
