Ouroboros: Handshake + EtherSync
After watching too many "privacy" apps get subpoenaed or shut down, I wanted a communication tool that literally cannot be shut down because it has no servers to seize. Ouroboros is a Rust-based P2P stack with two modes: 1. Live sessions: Two peers connect directly using just a shared passphrase. The passphrase deterministically generates identical network parameters on both sides, so they can find each other without any coordination server. 2. EtherSync spaces: Async file sharing and messaging in encrypted "spaces" that sync via gossip protocol when peers are online. Key features: -…

What it does
Ouroboros is an open-source framework for private communication without centralized discovery servers. It combines Handshake (deterministic 1:1 secure sessions with QR flows and network fallback) and EtherSync (passphrase-derived encrypted spaces for async messages and chunked file sharing). This launch adds a guided desktop UX, robust daemon lifecycle (reconnect/reclaim/live logs), runtime diagnostics, and backlog replay on rejoin for recent EtherSync history.
P2P FRAMEWORK Private communication, encrypted shared spaces, and route emergence from inside the same secret context. - OmarPrampolini/Ouroboros

Hey HN! I’ve written a bunch of WebSocket servers over the years to do simple things like state synchronization, WebRTC signaling, and notifying a client when a backend job was run. I realized that if I had a simple way to create a private, temporary, mini-redis that the client could talk to directly, it would save a lot of time. So we created DriftDB. In addition to the open source server that you can run yourself, we also provide https://jamsocket.live where you can use an instance we host on Cloudflare’s edge (~13ms round trip latency from my home in NY). You may have seen my…
Neosync – Open-Source Data Anonymization for Postgres and MySQL2024 · github.com · ▲246Hey HN, we're Evis and Nick and we're excited to be launching Neosync (https://www.github.com/nucleuscloud/neosync). Neosync is an open source platform that helps developers anonymize production data, generate synthetic data and sync it across their environments for better testing, debugging and developer experience. Most developers and teams have some version of a database seed script that creates some mock data for their local and stage databases. The problem is that production data is messy and it’s very difficult to replicate that with mock data. This causes two big…
An Elliptic Curve-Based Secure Chat, Written Using Rust and Protobuf2024 · github.com · ▲66This is a project I made to learn more about crypto. I've also written a [post](https://vaktibabat.github.io/posts/ecurvechat/) that explains all the crypto concepts and algorithms used in the project, and how I implemented them. I'd be very glad for any feedback about both the code and the post :)

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
