Use Case: Securing Financial Transactions with ZTT

In the financial world, milliseconds matter. But modern security often overlooks the dimension of time, creating a critical vulnerability: the "Store now, execute later" attack. A hacker can intercept a valid, signed transaction request and re-submit it minutes or hours later to exploit a favorable market shift. Temporal Zero Trust (ZTT) from Timeverse closes this loophole.

The Attack

1. A user initiates a stock purchase, creating a signed API request.
2. An attacker on the network intercepts and copies this valid request.
3. The attacker waits 15 minutes for the stock price to drop.
4. The attacker resubmits the original, valid request, profiting from the price difference at the user's expense.

The Timeverse ZTT Defense

With Timeverse, the API request is wrapped in a `SignedTemporalRequest`. Here's how it neutralizes the attack:

• Ephemeral Validity: The original request is generated with a validity window of just a few seconds (e.g., Ticks 500 through 600 of Cycle 12345).
• Contextual Verification: When the attacker resubmits the request 15 minutes later, the banking server's Timeverse gateway immediately checks the temporal context. It sees the current cycle and tick window are far outside what the request specifies.
• Instant Rejection: The request is rejected as having an "Invalid Temporal Context." The signature is correct, but the *phase* is dead. The attack fails completely.

By binding execution to a precise and fleeting temporal window, ZTT makes stolen credentials and requests instantly perishable, providing a new, fundamental layer of security for the financial industry.
