# Handshake: Acknowledge ("verack")

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`.

This `verack` message consists of only a message header; the command string is "verack".
