Types

type Chain

type Chain func() error

Chain represents the next stage in the boot process.

func Reset

func Reset(storagePath string) (Chain, error)

Reset is intended to emulate the early stage boot process of a device.

It's separate from the device emulator code to highlight that the process of verifying the local firmware/proofs/etc. could be done on-device at as part of the boot-ROM execution to provide some tamper-resistant properties to the firmware installed on the device.

Other, real-world, devices with secure elements may be able to optimise this process by checking once and leveraging properties of the hardware.

Returns the first link in the boot chain as a func.
