State

In persisted KV store

1. Global unique capability index
2. Capability owners

Indexes:

• Unique index: []byte("index") -> []byte(currentGlobalIndex)
• Capability Index: []byte("capability_index") | []byte(index) -> ProtocolBuffer(CapabilityOwners)

In-memory KV store

1. Initialized flag
2. Mapping between the module and capability tuple and the capability name
3. Mapping between the module and capability name and its index

Indexes:

• Initialized flag: []byte("mem_initialized")
• RevCapabilityKey: []byte(moduleName + "/rev/" + capabilityName) -> []byte(index)
• FwdCapabilityKey: []byte(moduleName + "/fwd/" + capabilityPointerAddress) -> []byte(capabilityName)
