Memory Management -The WebAssembly module manages memory explicitly through the `allocate` function, which allows the host to request memory regions where it can write data. This pattern provides: +The WebAssembly module manages memory explicitly through the `allocate` function for internal operations. Data exchange with the host occurs through host functions rather than direct memory sharing: -- **Safe data exchange**: Complex data structures like JSON can be safely passed between the host and WebAssembly module. -- **Memory control**: The WebAssembly module maintains control over its own memory. -- **Explicit ownership**: Memory allocation and access patterns are clearly defined for both the host and the module. +- **Host function interface**: Transaction and ledger data is accessed via standardized host functions. +- **Memory isolation**: The WebAssembly module maintains control over its own memory space. +- **Deterministic access**: Host functions provide consistent, validated data access patterns. -Since WebAssembly modules have their own linear memory, this explicit allocation mechanism creates a standard protocol for hosts to interact with the module's memory space. +This approach ensures secure and predictable data exchange between the host environment and WebAssembly modules. ## 4.
