Ouroboros: Handshake + EtherSync
Deterministic P2P sessions and encrypted gossip spaces.
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.

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…

Hey 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…
