# Handshake: Acknowledge ("verack")
2019-12-22 17:37:40 -05:00
The `verack` message is sent in reply to a [version ](/protocol/network/messages/version ) message.
Sending a `verack` in response to a `version` message indicates to the remote that its connection and version has been accepted.

There is no version negotiation functionality between nodes; therefore if the node does not accept the version supplied by the remote then the node disconnects instead of responding with a `verack` .
