A `blocktxn` message is sent in response to a [`getblocktxn`](/protocol/network/messages/getblocktxn) message, and must include exactly the set of transactions requested, in the order requested (i.e. in the order they appear in the block).
| transactions | variable | `transaction count` [transactions](/protocol/blockchain/transaction) | The transactions, in order, serialized as though in a [`tx`](/protocol/network/messages/tx) message. |
