Kairos Vault

What it does

Kairos Vault is the first zero-knowledge, decentralized time capsule that cryptographically seals your files until a future date. Unlike traditional cloud storage or scheduled emails, Kairos Vault uses the Drand network to mathematically guarantee that no one can access your data a second before the timer expires. It replaces human trust with pure cryptography.

  Keeper – embedded secret store for Go (help me break it)Apr 2026 · github.com · ▲64

  Keeper is an embeddable secret store (Argon2id, XChaCha20-Poly1305 by default). Four security levels, audit chains, crash-safe rotation. Vault is overkill for most use cases. This is for when you ge paranoid about env and need encrypted local storage that doesn't suck. No security through obscurity, hence, It's still early, so now's the best time to find weird edge cases, race conditions, memory leaks, crypto misuse, anything that breaks. The README has a full security model breakdown if you want to get adversarial.

  Vaultrice – A real-time key-value store with a localStorage API2025 · vaultrice.com · ▲43

  Hi HN, I'm Adriano, one of the makers of Vaultrice. I'm excited (and a little nervous!) to share what we've been building. For years, we found ourselves in a frustrating loop: whenever we needed a simple real-time feature—like a "who's online" list, a collaborative app, or just sharing state between a marketing site and our main app — we'd end up spending days setting up the same stack or discarded to do it. Setting it up, it always involved wiring together a database, a WebSocket server, an API, and managing the connection state. It felt like massive overkill for what we were trying to…

  Needle: We Distilled Gemini Tool Calling into a 26M Model▲776

  Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
