Permission control refers to the mechanisms that regulate access rights and privileges for users or entities within a system or network. It defines who can perform specific actions, view certain data, or interact with particular resources. This security feature ensures that only authorized parties can execute designated operations. It is crucial for data integrity and system security.
Context

News reports on regulatory compliance often address how permissioned blockchain solutions utilize these controls for enterprise use cases. Proper implementation of permission control helps maintain system security and data privacy.
