Enterprise blockchain is a new technology trend that brings the power of blockchain technology to the enterprise domain. However, developing and maintaining a blockchain system is not an easy task. These types of systems are very sophisticated with many layers of networking and software components. State-of-the-art solutions are fragmented into different independent layers and mostly do not offer a complete workflow of developing, deploying, operating, and maintaining an enterprise blockchain application. This paper introduces akaChain, an enterprise Blockchain as a Service platform. Based on Hyperledger Fabric, akaChain provides a portable solution for deployment on different infrastructures, software development kits for developers, middleware utilities for administrators, and off-the-shelf application templates for businesses to quickly release new products. akaChain is currently running multiple live enterprise blockchain networks that serve more than 20 thousand users in three main practical use cases: Loyalty and Rewards Network, electronic Know-your-Customer, and Assets Traceability. This paper will provide a brief overview into the context of the needs and challenges of the industry that drives akaChain motivation of an ideal enterprise blockchain platform; the complete akaChain solution package and use cases that were developed and run on live blockchain networks.
