The global interaction system works as follows. Each chip that needs to send a global interaction, first sends an interaction with `InteractionKind::Global` locally. Then, the `GlobalChip` receives these local interactions with `InteractionKind::Global`, then converts these messages into digests and accumulates them, making the results global.

However, while these informations are sent locally with `InteractionKind::Global`, there are actually two different "actual" `InteractionKind`s - `Memory` and `Syscall`.
However, while these information are sent locally with `InteractionKind::Global`, there are actually two different "actual" `InteractionKind`s - `Memory` and `Syscall`.

The vulnerability was in that the actual underlying `InteractionKind` was not sent as a part of the local interaction between the chips and `GlobalChip`. Therefore, a "memory" interaction could be regarded as "syscall" interaction, and vice versa.
