API Overview

Updated at: Nov 22, 2018 GMT+08:00

HUAWEI CLOUD block chain service (BCS) provides users with one-stop installation and management functions, greatly simplifying BCS deployment. BCS is based on the open source project Hyperledger Fabric. Users need to use the Fabric software development kit (SDK), which may be huge in size, to invoke chainchodes when developing blockchain applications. This also requires users to devote more time and energy for learning. The APIs of BCS are designed to help users easily use the service and improve development efficiency.

Most programming languages of applications provide native support for calling RESTful API, and most customers have experience in using RESTful API services. Therefore, the Fabric SDK invocation process is embedded in the RESTful APIs of BCS, eliminating the need of users to directly use the Fabric SDK for chaincode invocation.
