Abstract
Methods, apparatus and systems for verifying coin ownership are disclosed. In an embodiment, a coin service provider identifies an online session initiated by a wallet application and a next coin to verify, receives information associated with the next coin from a wallet application, determines that ownership of the next coin was transferred out of the wallet application since the last time coins in the wallet application were verified and that ownership of the next coin has not been updated in a coin data store. The coin service provider then transmits a prompt to the user device for the user to confirm that a transaction involving the next coin completed successfully, receives a confirmation message from the user device, confirms that the next coin was received by a recipient, and next updates ownership information of the next coin in the coin data store.
