New page

On connect, [[Protocol specification#version|version]] and [[Protocol specification#verack|verack]] messages are exchanged, in order to ensure compatibility between peers.

==Version Handshake==

When the local peer (L) connects to a remote peer (R), the remote peer will not send any data until it receives a version message.

L -> R: Send version message with the local peer's version
R -> L: Send version message back
R -> L: Send verack message
R: Sets version to the minimum of the 2 versions
L -> R: Send verack message after receiving version message from R
L: Sets version to the minimum of the 2 versions

Note: A version number of 10300 is converted to 300 before being processed and versions below 209 are no longer supported.
