Horizon has the opportunity to download any transaction for offline storage.
The resulting data upload includes the entire branch from the root operation of a single bush of transactions to the current transaction.
Unloading is self-sufficient, despite its small size (up to 100kb). Access to the entire public network is not required to verify integrity.
You can download the transaction from the page of each transaction in the Operations Monitor of the Horizon public network - https://ankhorizon.com
Example transaction: https://ankhorizon.com/transaction/e0188db5-5de4-4cf5-8469-96a257fc015b
