trait GetBlocksMessage extends DataPayload

The getblocks message requests an inv message that provides block header hashes starting from a particular point in the block chain. It allows a peer which has been disconnected or started for the first time to get the data it needs to request the blocks it hasn’t seen.

Abstract Value Members

  1. abstract def blockHeaderHashes: Seq[DoubleSha256Digest]

    One or more block header hashes (32 bytes each) in internal byte order.

    One or more block header hashes (32 bytes each) in internal byte order. Hashes should be provided in reverse order of block height, so highest-height hashes are listed first and lowest-height hashes are listed last.

  2. abstract def hashCount: CompactSizeUInt

    The number of header hashes provided not including the stop hash.

    The number of header hashes provided not including the stop hash. There is no limit except that the byte size of the entire message must be below the MAX_SIZE limit; typically from 1 to 200 hashes are sent.

  3. abstract def protocolVersion: ProtocolVersion

    The protocol version number; the same as sent in the version message.

  4. abstract def stopHash: DoubleSha256Digest

    The header hash of the last header hash being requested; set to all zeroes to request an inv message with all subsequent header hashes (a maximum of 500 will be sent as a reply to this message; if you need more than 500, you will need to send another getblocks message with a higher-height header hash as the first entry in block header hash field).

    ASCII string which identifies what message type is contained in the payload. Followed by nulls (0x00) to pad out byte count; for example: version\0\0\0\0\0. Command names need to be 12 bytes long This is generally used to build a org.bitcoins.core.p2p.NetworkHeader
