Class GetHeadersMessage

  • public class GetHeadersMessage
    extends GetBlocksMessage

    The "getheaders" command is structurally identical to "getblocks", but has different meaning. On receiving this message a Bitcoin node returns matching blocks up to the limit, but without the bodies. It is useful as an optimization: when your wallet does not contain any keys created before a particular time, you don't have to download the bodies for those blocks because you know there are no relevant transactions.
