The Amazing Ledger is a double-entry accounting system used to record transactions. The entries are processed, validated and persisted to a database and their original data is never modified.

The Amazing Ledger records a journal that keeps track of all credits and debits to and from accounts (an account being anywhere money can go, not necessarily a bank account).
Since it is a double-entry accounting system, there must always be a debit from at least one account for every credit made to another account, therefore all entries must balance to zero within a transaction.
For example,
| Account | Amount |
|---|---|
| Satoshi Nakamoto | $ -50 |
| Hal Finney | $ 50 |
The system supports the following account types:
- equity: Represents your net worth. This will be used to start the ledger and its values are naturally negative.
- asset: Represents the money you have, where money sits. The values of theses accounts are naturally positive.
- liability: Represents the money you owe and is a synonym to debt. The values of theses accounts are naturally negative.
- expense: Represents the money you spent, where money goes. The values of theses accounts are naturally positive.
- income: Represents the money you have earned, where money comes from. The values of theses accounts are naturally negative.
