As artificial intelligence increasingly handles transactions, vulnerabilities in digital systems could lead to significant issues. The core challenge in ensuring digital trust might not be verifying that something occurred, but rather confirming that nothing took place.
When a server sends a command to another, network disruptions can block the response even after the action is completed. From the sender’s perspective, a successful operation and one that never started can appear indistinguishable.
Engineers have created methods to address this ambiguity, such as using unique keys to prevent duplicate actions from accidental repeated requests. Companies like Stripe and AWS implement similar strategies in services where retrying a command should not trigger repeated outcomes.
Workflow platforms, including Temporal, maintain progress during system interruptions. While these measures are key, they should not be confused with definitive proof of events across separate systems.
The industry is actively preparing for autonomous payments, with EMVCo releasing a draft framework for AI-initiated card transactions. This framework focuses on how systems verify consumer authorization for AI agents to execute transactions. Authorization and execution proof are distinct requirements.

An autonomous system, even properly authorized and within spending limits, might repeat a transaction if it cannot confirm whether an earlier one was completed. The emerging framework for autonomous transactions requires three key assurances: proof of authorization, proof of the final result, and proof of rejection or prevention.
Digital receipts typically validate completed actions, but what proof should customers receive when an autonomous system claims a transaction was not completed? A basic confirmation or AI-generated explanation is inadequate. A reliable solution demands authoritative records tied to unique transaction identifiers.
The entity responsible for executing an action must determine if it was completed, rejected, canceled, or remains pending. Verification necessitates durable transaction IDs, consistent state changes, controlled retries, and reconciliation between systems. Digitally signed records could offer additional security for sensitive transactions.
If an institution cannot confirm whether a command succeeded, the correct status is unresolved, not failed. Until this uncertainty is cleared, an autonomous agent should avoid issuing a new command that could duplicate the transaction. EMVCo’s framework is a step forward, but continued development is essential to ensure proof of events across independent systems.
