This endpoint is used to validate ledger blocks against a channel owned by the given peer.

Block validation does the following:

• Parses local blockchain ledger files.
• Verifies the integrity and data format.
• Collects statistics such as block size, number of transactions, etc.

The following example shows how to validate blocks by submitting a GET request on the REST resource using cURL.

curl -u <username>:<password> -X GET \
  "https://<rest_server_url:port>/console/admin/api/v2/nodes/peers/<peerId>/blockaudit/<channelName>"

For example,

curl -u myname@oracle.com:mypswd\
 -X GET "https://myvm.oracle.com:10001/console/admin/api/v2/nodes/peers/devpeer04/blockaudit/devchannel02"
