What it does
Can you prove your AI agent was authorized before it acted — not after? Authproof creates cryptographic delegation receipts before every agent action. Tamper-evident log. HIPAA, SOC2, EU AI Act compliance exports. Multi-tenant support for managed AI companies. Free tier — 1,000 receipts/month. No credit card. Audit logs are post-hoc evidence. Receipts are pre-hoc constraints.
Cryptographic pre-execution authorization for AI agents. Signed receipts before every action. Tamper-evident audit trails. Built for regulated environments.
Most agent authorization protocols enforce against a policy the operator defines. AuthProof is different: your users sign the authorization object with their own private key, and that signature gates execution. Before any action runs, the live model state is measured and compared to what was measured at authorization time. Drift blocks execution. The user's intent is the constraint, not an operator-managed policy that can be rewritten after the fact. Most AI agent deployments use a trust score. Good action, score goes up. Bad action, score goes down. Sounds reasonable. But a patient attacker does one bad thing, one good thing, one bad thing, one good thing. The score never hits zero. The…from cloud.authproof.dev

Built a ~9M param LLM from scratch to understand how they actually work. Vanilla transformer, 60K synthetic conversations, ~130 lines of PyTorch. Trains in 5 min on a free Colab T4. The fish thinks the meaning of life is food. Fork it and swap the personality for your own character.

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
