Vitnify Wants AI Agents to Produce Receipts

Why it surfaced

The site makes a precise promise: record an agent's exact logits, tool calls, and results so a run can be recomputed bit-for-bit and verified offline. Its open-source presentation includes a Rust engine, signed receipts, a paper, an attack matrix, and an unusually memorable commandment for agent infrastructure: “reproduce, don't trust.”

Vitnify wraps LangGraph and MCP agents in a system for capability containment, deterministic replay, and cryptographically verifiable execution receipts.
