Ledger

The ledger is an immutable record in a database running on a node of all actor interactions and states of a node, supporting real-time and historical observation for learning and security. Every actor request, response, and notification is written to the respective ledgers involved in actor collaboration and communication. Each node implements its own ledger of all actor activity.

Ledgers represent the decisions of an organization in a standard, unified way. No work is done by developers to use the ledger. Each actor activity over the network using PnCP is written to a ledger. Once something becomes an actor, its decisions (input/output) are recorded.
