Preparations

User applications interact with the ledger using chaincodes. An application can be written in a variety of languages, including Go, Solidity, Java, C++, Python and Node.js. The languages used by the application and the chaincode do not necessarily have to be the same, as long as the application can invoke the chaincode using the SDK.

Create a BCS instance.
BCS instances can be deployed in CCE clusters. For details, see Using a CCE Cluster.
Obtain the required SDK configuration file and certificates. For details, see BCS Access.
