# Your AI Agents Are Talking — But Can You Prove What They Said?

Your AI Agents Are Talking — But Can You Prove What They Said? AI agents are no longer “helpers.” They move money, make decisions, and talk to each other. If you have at least two agents, you’re already in a multi‑agent system — whether you planned for it or not. PiQrypt is an open‑source trust layer that ensures every interaction between your agents is cryptographically verifiable . Even if your agents change, your LLMs evolve, or your infrastructure migrates — PiQrypt stays as the immutable proof layer on top. The gap nobody talks about Modern AI stacks are incredibly powerful: LLMs : OpenAI, Anthropic, Mistral, DeepSeek, local models. Agent frameworks : LangChain, CrewAI, AutoGen, custom agents. Observability tools : logs, traces, dashboards. They all share a blind spot: “They can show you what happened — but they can’t prove it.” Logs can be modified. Traces aren’t cryptographic. And when agents interact, there’s no shared, verifiable record of that interaction. When something goes
