case class HeadersMessage(count: CompactSizeUInt, headers: Vector[BlockHeader]) extends DataPayload with Product with Serializable

The headers message sends one or more block headers to a node which previously requested certain headers with a getheaders message.

count

Number of block headers up to a maximum of 2,000. Note: headers-first sync assumes the sending node will send the maximum number of headers whenever possible.

headers

Block headers: each 80-byte block header is in the format described in the block headers section with an additional 0x00 suffixed. This 0x00 is called the transaction count, but because the headers message doesn’t include any transactions, the transaction count is always zero.
