Industrial block chain network optimization method and device, node and storage medium

The embodiment of the invention discloses an optimization method and device of an industrial block chain network, a node and a storage medium, the method is applied to a block chain node of the industrial block chain network, and the method comprises the following steps: receiving a first business transaction; determining a service attribute of the first service transaction; wherein the service attribute is used for representing whether the first service transaction has a time delay sensitive requirement or not; and sending the first business transaction marked with the business attribute to a consensus block chain node of the industrial block chain network, so that the consensus block chain node can determine a block outlet sequence of the first business transaction based on the business attribute. 本申请实施例公开了一种工业区块链网络的优化方法及装置、节点和存储介质，其中，所述方法应用于所述工业区块链网络的区块链节点，所述方法包括：接收第一业务交易；确定所述第一业务交易的业务属性；其中，所述业务属性用于表征所述第一业务交易是否具有时延敏感的需求；将标识有所述业务属性的第一业务交易发送至所述工业区块链网络的共识区块链节点，使得所述共识区块链节点能够基于所述业务属性确定所述第一业务交易的出块顺序。
