| index | Number | The operation index is used to ensure each operation has a unique identifier within a transaction. To clarify, there may not be any notion of an operation index in the blockchain being described. | |

For example, Bitcoin uses a network_index to identify which UTXO was used in a transaction. network_index should not be populated if there is no notion of an operation index in a blockchain (typically most account-based blockchains). | [optional] |
