Class NetworkMessage.BlockInventoryMessage

java.lang.Object

nxt.peer.NetworkMessage

nxt.peer.NetworkMessage.BlockInventoryMessage

Enclosing class:

NetworkMessage

public static class NetworkMessage.BlockInventoryMessage
extends NetworkMessage

The BlockInventory message is sent when a peer has received a new block. The peer responds with a GetBlock request if it wants to get the block.

• Block identifier (long)
• Previous block identifier (long)
• Block timestamp (integer)
• Transaction identifier list (ChainTransactionId)

The ordering of transactions in the transaction identifier list must be same as the one used by BlockBytes when returning block and transaction bytes, as the exclude transactions feature depends on this.
