Abstract
Systems and methods are disclosed for fault-tolerant hash control. In some examples, a hashing system receives a dataset. The controller apportions hashing calculations across hashing chips to calculate at least one hash digest based on the dataset. The hashing chips include at least a first hashing chip, a second hashing chip, and a third hashing chip. A first connector couples the first hashing chip to the second hashing chip. A second connector couples the second hashing chip to the third hashing chip. A backup connector couples the first hashing chip to the third hashing chip, bypassing the second hashing chip. The first hashing chip sends a communication to the third hashing chip along the backup connector that bypasses the second hashing chip in response to a determination that the second hashing chip is nonresponsive.
