Hello

I want to broadcast Bitcoin transactions using python's sock library.Now I can sign a transaction. But when sock is used to link other nodes, it is not known what information should be transmitted.The node I am linking to is protocol version 70016.I tried to find information on bitcoin.org.

This is the site I was looking for:
https://developer.bitcoin.org/reference/p2p_networking.html#protocol-versions

But it doesn't show how protocol 70016 works.I want to know which website I should visit for the 70016 version of the Bitcoin protocol.
