Use the Fabric Gateway to Develop Applications

Applications can use the Fabric Gateway client API to run queries and updates on the ledger.

You can install and use the Fabric Gateway client API to develop applications for Oracle Blockchain Platform. Fabric Gateway is available for Go, Node.js, and Java.

The REST APIs provided by Oracle Blockchain Platform have been created with maximum flexibility in mind; you can invoke a transaction, invoke a query, or view the status of a transaction. See REST API for Oracle Blockchain Platform.

However, this flexibility means that you'll likely want to wrap the existing API endpoints in an application to provide object-level control. Applications can contain much more fine-grained operations.

Previous versions of Hyperledger Fabric supported the Hyperledger Fabric SDK. Hyperledger Fabric SDK is now deprecated. To learn more about Fabric Gateway, including information on migrating existing applications from Hyperledger Fabric client SDKs to the Fabric Gateway client API, see Fabric Gateway.
