Function call sub-layer

Focus: Invocation and execution of functions across blockchains.

Objective: Allow execution of business logic across chains. Facilitate seamless and compliant execution of functions or operations across different blockchains, ensuring that a function initiated on one blockchain can trigger and execute corresponding logic on another, all while adhering to regulatory requirements.

Description: Provides standards and protocols for calling functions like smart contracts across interconnected blockchains and synchronizing state changes. This layer is pivotal to achieving meaningful crosschain operations. It ensures that functions, especially those defined in smart contracts, can be executed not just within their native blockchain but can also invoke or be invoked by functions on other blockchains. In the context of regulated settings, it's essential that these crosschain function calls also adhere to the relevant regulatory and compliance standards. This might involve verifying the legitimacy of the calling function, ensuring data privacy and security, and ensuring that the operations do not violate any regulatory mandates.

Layer owner: Crosschain protocol developers, smart contract developers.
