 Effectively, the system calls of a program form the "API" with it and the rest of the computer. Commonly this is called the [ABI (Applcation Binary Interface)][abi] and is usually platform-specific. With Land, we are effectively creating a platform-independent ABI that just so happens to target Webassembly.
