Protocol Preamble
The first block sent by the multi view is always the protocol preamble:

Version: 2.3↵

The version field indicates the protocol version. When the protocol is changed in a compatible
way, the minor version number will be updated. If incompatible changes are made, the major
version number will be updated.
