Four companies showed a chain of trust for agent payments, rooted in DNS
At GovWare, during Singapore International Cyber Week, GoDaddy, Infoblox, Google and Cloudflare demonstrated an open reference architecture they call Chain of Trust, built with Singapore’s Infocomm Media Development Authority and aligned with its Model AI Governance Framework for Agentic AI, version 1.5. The subject is less glamorous than it sounds: how four parties who have never met verify that an agent is who it says it is, and that it is allowed to buy what it is buying.
The demonstration simulated a flight purchase from Madrid to Singapore. The buyer agent ran on Amazon Web Services, the seller agent on Cloudflare Workers, the mandate authority and the verifier on Google. A person approved the purchase with a passkey, and an independent approval service issued signed mandates under the Agent Payments Protocol setting what the agent could buy, from whom and up to what amount. Payment ran through Stripe in test mode.
Each layer rests on an open standard: discovery through Agent Resources Discovery or DNS-AID; identity through the Agent Name Service and SPIFFE for each running instance; authorization through OAuth; communication through A2A and MCP; payment through AP2 and the Universal Commerce Protocol; traceability through append-only logs with a signed receipt anyone can check offline; and a Trust Index that scores an agent from public attestations. Forkast’s account of the demo adds the verification machinery in the identity layer — DNSSEC and DANE, signed mandates carried as SD-JWT — and lands on the same limit: the payment layer still runs in test mode.
Why it matters for agents
The claim worth testing is not that a mock payment completed. It is where the trust lives. An agent’s identity is registered so any party can verify it from public evidence, rather than a certificate the agent presents inside one session. The log is append-only, so a later change to a record is visible to anyone who checks, and each layer is verified separately — which the companies put plainly: passing one check does not bypass the others.
The demo also included what should worry an agent operator more than the happy path. A look-alike seller and forged credentials were both stopped before a transaction occurred. A chain of trust that only works when everyone is honest is a formality; the useful test is whether the impostor fails, and at which layer it fails.
Two things follow for agents. Identity becomes portable: the same signed identity can be checked by a merchant, a payment provider and an auditor without any of them owning the registry, because the root is DNS and public logs. And identity becomes public: the Trust Index is computed from attestations rather than self-description, a different regime from an agent asserting its own capabilities in a system prompt.
The caveats are structural. This is a coalition of vendors demonstrating on mock rails: no production deployment, no merchant obliged to accept AP2 or UCP mandates, and a protocol layer still being drafted. The $3 trillion to $5 trillion in agent-facilitated purchases by 2030 that the announcement cites is a McKinsey projection, not a measurement. What exists as of this week is a reference architecture, and an invitation to DNS operators, registrars, identity providers and payment networks to adopt it.
