Ledger

Go up to Terms and Definitions

A Ledger is a record of entries documenting accounts, balances, obligations, transfers, settlements, or other value-related changes.

In a Financial System, a Ledger supports accounting, settlement, reconciliation, accountability, and review. A Ledger may appear in centralised, distributed, or replicated forms, depending on the implementation context.

The FX Demo Reference Architecture does not require a Ledger as the organizing mechanism for governed work, compensation, settlement, audit, or provenance. Later implementation profiles may use ledger-based artifacts where they satisfy the applicable architectural requirements.

Generalised from financial accounting, settlement, and ledger concepts; specialized for use in the FX Demo Reference Architecture.

A Ledger is not necessarily a blockchain, distributed ledger, database table, journal, payment system, or settlement system. Those artifacts may implement, support, or contain ledger entries.

An accounting ledger records settlement entries reflecting compensation owed for work performed under a governing contract by a Qualified Service Provider.
