Block Browser

You can query blockchain information required for maintenance, including the block quantity, transaction quantity, block details, transaction details, performance, and peer statuses.

To access blockchain browsers, set the blockchain network access address to a private address of the cluster and ensure that the network between the user and cluster is connected. If you set the access address to an EIP bound to the cluster, unbind the EIP when you are not using the blockchain browser.
