Batch validates a collection of out-of-order messages by multiple authors. No previous message checks are performed, meaning that missing messages are allowed, the collection is not expected to be ordered by ascending sequence number and the author is not expected to match between current and previous message.

It expects the messages to be the JSON encoded message of shape: {key: "", value: {...}}
