Neutron SCCS
The SCCS is a stack data structure which serves as the sole non-permanent method for communication between the smart contract VMs and the backing blockchain. It is also used for communication between different types or instances of smart contract VMs. This includes for instance calling a WASM smart contract from an x86 smart contract and sending/recieiving data between the two smart contracts. The following can be considered templates of how the SCCS looks in different scenarios when the VM begins execution
Note in all of these the bottom of the template is the first item to be popped off.
