## Isolated Execution Domain

An isolated execution domain is a secure partition within a computing system where code runs independently of the main operating system and other applications. This separation is achieved through hardware-enforced memory management and access controls, ensuring that the isolated code cannot be interfered with or monitored by external processes.

This concept is fundamental to the architecture of Trusted Execution Environments and secure microcontrollers. In finance, this domain is used to process sensitive operations like private key signing, biometric data matching, or transaction validation.

Because the domain is isolated, it remains secure even if the primary OS is infected with malware or viruses. It acts as a black box that takes inputs, performs a secure computation, and outputs the result without exposing the intermediate data.

This architecture is vital for maintaining security in increasingly complex and connected digital environments. It allows developers to run critical applications on devices that are otherwise insecure or open to the internet.
