BlkSeal
Hi HN — I built an experimental demo that creates and verifies revocable digital signature artifacts using deep learning encoding models instead of traditional cryptographic keys. In this system, a specific model instance encodes file metadata into a signature artifact. That same model instance is required to verify it. Signing authority is controlled through a short-lived “lease” (15 minutes), and can be revoked to intentionally invalidate verification. This is not RSA/ECDSA, and I’m not making cryptographic claims or guarantees. I’m exploring whether the encoding method combined with…

What it does
A modern platform for content integrity, BlkSeal allows you to prove the origin of digital content, detect unauthorized changes, and manage trust over time. Powered by BlkBolt, the platform provides revocable signing authority to help ensure the long-term integrity and authenticity of shared files and information. Digital content moves fast. BlkSeal gives it a verifiable integrity layer so people and systems can check origin, changes, authority, and trust.
Sign, share, and verify trusted digital content with BlkSeal. Prove origin, detect changes, and manage trust over time with BlkBolt-powered signatures.
BlkSeal™ helps people, applications, AI agents, and automated workflows prove where content came from, when it was created, whether it changed, and whether it should still be trusted. Use it to add verifiable integrity to files, AI responses, API outputs, documents, reports, media, and other digital assets. Powered by BlkBolt™, lyfe.ninja's model-based encoding technology. Show that content came from your application, workflow, AI agent, organization, or account. Verify whether signed content still matches the original, or whether it has been modified, replaced, or tampered with. Tie signed content back to a valid signing authority so teams can verify who or what produced it, when it was…from lyfe.ninja

Artifact Keeper – Open-Source Artifactory/Nexus Alternative in RustFeb 2026 · github.com · ▲166I'm a software engineer who keeps getting pulled into DevOps no matter how hard I try to escape it. I recently moved into a Lead DevOps Engineer role writing tooling to automate a lot of the pain away. On my own time outside of work, I built Artifact Keeper — a self-hosted artifact registry that supports 45+ package formats. Security scanning, SSO, replication, WASM plugins — it's all in the MIT-licensed release. No enterprise tier. No feature gates. No surprise invoices. Your package managers — pip, npm, docker, cargo, helm, go, all of them — talk directly to it using their native…
Let's Seal – Let's Encrypt for document signing, free and self-hostedJul 2026 · github.com · ▲94TLDR, Let's Seal gives the finger to Adobe and every doc signing tool (docusign, google, etc) who pay to play with the Adobe Approved Trust List and then charge you for something that should be free. Currently even the person checking if a document/contract is sealed or code is authentic has to also be inside the same Adobe walled garden too. Verification, the part that should be free is the part everyone charges for. Thats the shape Let's Encrypt fixed for TLS, and I wanted the same thing for documents and files. The core idea therefore needed to go a bit beyond e signatures and i…

I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…

OpenSEO▲928Hello! For the last 2 months, I've been building OpenSEO. It's a user friendly UI wrapping the DataForSEO API which has high quality SEO data for keywords, backlinks, AI SEO and competitor research. Instead of paying $100+ per month, you buy DataForSEO credits and pay only for usage. The coolest thing about the project so far has been hearing about what people are building on top of it. People are using coding agents to quickly integrate with Google Search Console, Google Ads and building their own AI SEO and reporting features. Many were already building their own custom solutions around…
