Oracle is focused on improving its blockchain platform by continuously releasing new and enhanced features to support our rapidly growing user base. In July, we made the following enhancements:-

  1. Support for Hyperledger Fabric 1.1 which has some of the following features and capabilities:-
  • Node.js chaincode support: With the support of Hyperledger Fabric 1.1, Node.js chaincodes are now also supported thus appealing to a wide array of developers who find Node.js easier to work with than other languages as well as the fact that it has a wider array of developers’ tools
  • All SDKs(Node.js, Java and GO) and Fabric CA are now updated to support Hyperledger Fabric 1.1
  • Connection profiles are supported and can be generated from the OABCS console
  • Developer packages and samples, available in the App Dev area of the console’s Developer’s Tools tab, were updated to use connection profiles
  • Attribute-based access control (ABAC) is supported

 

  1. SQL- based rich queries
  • It is now much easier to compose business queries that can be understood by blockchain. OABCS chaincodes can use SQL to create rich queries for state-of-the-world
  • OABCS chaincode rich queries can use CouchDB query syntax for compatibility

 

  1. New peer alias field
  • This field can be used to append the peer’s name with an alias that helps one easily identify the peer and what it is used for

 

  1. Transient map and REST proxy
  • A transient map can be used to pass data when you invoke or query a chaincode from REST proxy.

 

  1. Chaincode container optimization
  • Older versions of chaincode are stopped when a new version of chaincode is instantiated on a channel. This frees up system resources consumed by unused chaincode containers.

 

In summary, Oracle is committed to continually update its blockchain platform to improve performance, keep pace with developers’ needs, and make it easier to build, deploy and manage blockchain networks. We take feedback from our rapidly expanding user base and turn that feedback into features that will help improve the overall service.
