Hi HN. This week Meta acquired Moltbook (agent social network), OpenAI acquired Promptfoo (agent testing), and Mandiant's founder raised $190M for Armadin. Agent infrastructure is clearly where things are heading.

We built AgentSign -- a zero trust engine for AI agents. The problem: agents are operating without any identity infrastructure. Moltbook went viral for fake posts because there was zero verification on who or what was posting.

AgentSign gives every agent a cryptographic identity certificate, signs every action into an execution chain, and runs runtime code attestation before anything executes. There's also an MCP Trust Layer for agent-to-MCP server verification, and a Stripe-powered Trust Gate for agent payments.

5 subsystems: identity certs, execution chain verification, runtime code attestation, output tamper detection, and cryptographic trust scoring.

Free and open source. Built in London.

SDK: https://github.com/razashariff/agentsign-sdk

Happy to answer questions.

V interesting. Does the passport have history of what the agent has done in the past and if so, how are you able to verify that work? Specifically thinking about agents that may work across different systems.

Might be worth checking this out: https://www.8004.org/ it's more crypto specific but trying to tackle the problem of verifying an agent cross platforms.
