Where do you see a version field in the "getheaders" message? "getheaders" has two parameters, locator and hashStop. Of course, each block header has the block header version.

"getheaders" has two parameters, locator and hashStop. It says there is a version field in the protocol spec (https://en.bitcoin.it/wiki/Protocol_specification#getheaders). However, I should have read it more closely, version means the protocol version, so nevermind.

"getheaders" receives two parameters, a block-locator object and a hashStop. Inside the block-locator object, there is a version for that locator data structure only. The version applies to the locator object, not getheaders message as a whole or hashStop parameter. |
