# StorageServiceImpl

`open class StorageServiceImpl : SingletonSerializeAsToken, TxWritableStorageService`

### Constructors

<init> | `StorageServiceImpl(attachments: AttachmentStorage, validatedTransactions: TransactionStorage, stateMachineRecordedTransactionMapping: StateMachineRecordedTransactionMappingStorage)`

### Properties

attachments | `open val attachments: AttachmentStorage` Provides access to storage of arbitrary JAR files (which may contain only data, no code).
stateMachineRecordedTransactionMapping | `open val stateMachineRecordedTransactionMapping: StateMachineRecordedTransactionMappingStorage`
validatedTransactions | `open val validatedTransactions: TransactionStorage` A map of hash->tx where tx has been signature/contract validated and the states are known to be correct. The signatures arent technically needed after that point, but we keep them around so that we can relay the transaction data to other nodes that need it.

### Inherited Functions

toToken | `open fun toToken(context: SerializeAsTokenContext): SerializationToken`
