What Coin Age means here.

Bitcoin exposes the creation time of each live output. Bathymark can classify UTXO age exactly under its published 155-day method, while keeping clear that outputs are not people or beneficial owners.

What this cannot prove

A UTXO is not a person, wallet, investor, or beneficial owner. The owned node and indexer must be healthy before data can be published.

What would activate it

An exact chain source connection, historical completeness test, rights contract, reconciliation receipt, label-confidence policy where relevant, and bounded storage path.
