How administrators connect to, create, and access a blockchain-IoT Device ID (Deprecated)(IoT Device ID)-阿里云帮助中心

This topic describes the process for connecting to a blockchain. A successful connection creates a dedicated channel for that blockchain, which is used for all subsequent access.

Add a blockchain

Log on to the product console.
In the navigation pane on the left, choose IoT Blockchain Hub > Business Chains.
Click the Create Business Chain button to create a business chain for connecting to an enterprise blockchain.
