Append-only ledger
Append-only ledger is a data structure that only permits adding new records, never updating or deleting existing ones, preserving full history. For append-only ledger, the important details are the accounting period, source evidence, reviewer, materiality threshold, and control purpose that make the treatment auditable during close, reporting, and later review.
Also known as append-only log, write-once ledger
Why it matters
Understanding append-only ledger matters because close, reconciliation, and audit work depend on consistent timing, source evidence, review thresholds, and ownership. A loose definition creates avoidable rework. An append-only design adds new records without modifying past ones, which is what lets a system keep a complete history. Pluvo preserves prior states this way, so the version of a number a decision used stays intact even after newer data arrives.
In practice
Close example
Teams use append-only ledger during close, review, or audit support when a balance or transaction needs evidence. The controller should be able to trace the number to source records, timing, reviewer, and control threshold.
