# Freshness

|  |  |
| --- | --- |
| **Policy** | Freshness |
| **Type** | Sourcing policy (Radix-specific) |
| **Derived from** | [Verifiability](/policy/verifiability) |
| **Applies to** | Every factual page |
| **Threshold** | 180 days since last verification |
| **Enforcement** | Automatic _May be outdated_ notice; _Last Verified_ stamp |
| **Adopted** | 31 July 2026 |

**Freshness** is RADIX Wiki's crypto-native extension of verifiability. Facts about a fast-moving ecosystem decay quickly, so a claim that was sourced correctly a year ago may now be wrong.[[1]](#ref-1) Factual pages should record when they were last checked and be re-verified against the live ledger.

## How verification is recorded

Every page has a _Last Verified_ field, set when its facts are re-checked against sources and the live ledger. The stamp is separate from the last edit: fixing a typo does not re-verify a page, and confirming that a page is still correct does not require changing a word of it. Where a page has never been verified the field is empty, and nothing is shown beside the version and revision count.

The stamp is written by the rotating maintenance sweep, which runs `scripts/mark-verified.mjs` against the database.[[3]](#ref-3) The article editor has no control for it, so an editor who re-checks a page cannot record that they did – the sweep is the only thing that can. Read on 19 August 2026, 180 of the wiki’s 363 pages carry a verification stamp and 183 have never been verified – and every stamp on the wiki was written by the sweep, because nothing else can write one.

A page whose last verification – or, if it has never been verified, its last edit – is more than **180 days** old is treated as stale and shown a _May be outdated_ notice. That notice is generated at render time from the page’s own dates and is never stored on the page, so it cannot be dismissed by editing: it clears when, and only when, the page is verified again. No page currently meets the threshold. The oldest reading on the wiki is an unverified page last edited on 28 March 2026, 143 days ago. That render-time notice is also the only maintenance banner on this wiki that ever appears in quantity: the six an editor can place by hand sit on five pages in total, [counted and explained under verifiability](/policy/verifiability).

Where a page states an on-chain value, re-check it against a ledger explorer or the [Gateway API](https://docs.radixdlt.com/docs/network-gateway)[[2]](#ref-2) – the ledger is the authority, and published documentation about it can itself be out of date. The rotating audit that does this across the wiki records each pass in the [wiki maintenance log](/contents/tech/operations/wiki-maintenance-log).
