If you do not like to write boilerplate code repeatedly, or spend time to learn a new programming language supported by the Fabric chaincode.  You may want to check this out: https://github.com/open-dovetail/fabric-chaincode.git.  It is completely open source, and you can develop chaincode without any programming.  You need to know only JSON data format, and everything else is taken care of by the visual programming environment.  Please let me know if you see any issues.  I would also appreciate recommendations for improvement.
