A single distributed ledger of transactions. Ledger is a database that is distributed across multiple network nodes or computing devices. Each node receives data from other nodes and maintains a complete copy of the ledger. The nodes are updated independently of each other. Ledger is a mechanism which provides calculating and storage of balances and other changes caused by accepted transactions. For example, it marks spent transaction outputs and stores calculated [[Token]] ticker. At this moment ledger contains three datum types, related to financial aspects: - [[Token|tokens]] - [[Emission|emissions]] - [[5. Transactions Structure|transactions]] Ledger stores indexes of these datums and additional information which can be viewed through command - [[Node Command - LEDGER INFO]]
