请参阅图1，本申请实施例中一种房产交易方法的一个实施例可以包括：Referring to FIG. 1 , an embodiment of a real estate transaction method in an embodiment of the present application may include:
步骤S101、第一节点生成房产交易请求，并在所述房产交易区块链中广播所述房产交易请求。Step S101: The first node generates a real estate transaction request, and broadcasts the real estate transaction request in the real estate transaction blockchain.
所述第一节点为所述多个房产交易节点中的任意一个房产交易节点。The first node is any one of the plurality of real estate transaction nodes.
在所述房产交易区块链的任意一个房产交易节点上都可以触发房产交易的过程，为了方便描述，将触发交易的过程的节点称为第一节点。第一节点的交易人员可以在第一节点上设置交易，且第一节点将生成房产交易请求，并在所述房产交易区块链中广播所述房产交易请求。The process of real estate transaction can be triggered on any real estate transaction node of the real estate transaction blockchain. For convenience of description, the node that triggers the transaction process is called the first node. The trader of the first node can set the transaction on the first node, and the first node will generate a real estate transaction request and broadcast the real estate transaction request in the real estate transaction blockchain.
所述房产交易请求中包括当前待交易房产的详细信息，例如，地址、价格、建造时间、持有人、价格等等，并携带有所述第一节点的数字签名，使得接收到所述房产交易请求的其它房产交易节点可以获知其来源。The real estate transaction request includes detailed information of the current property to be traded, for example, address, price, construction time, holder, price, etc., and carries the digital signature of the first node, so that the property is received Other real estate transaction nodes that request a transaction can know their source.
所述第一节点将所述房产交易请求发送至第1级广播节点，所述第1级广播节点为与所述第一节点连接的房产交易节点；所述第1级广播节点在接收到所述房产交易请求后，将所述房产交易请求发送至第2级广播节点，所述第2级广播节点为与所述第1级广播节点连接的房产交易节点；所述第2级广播节点在接收到所述房产交易请求后，将所述房产交易请求发送至第3级广播节点，所述第3级广播节点为与所述第2级广播节点连接的房产交易节点；......；以此类推，第m级广播节点在接收到所述房产交易请求后，将所述房产交易请求发送至第m+1级广播节点，直至所述房产交易区块链中的各个房产交易节点均接收到所述房产交易请求为止，所述第m+1级广播节点为与所述第m级广播节点连接的房产交易节点，m为大于或等于1的整数。The first node sends the real estate transaction request to a level 1 broadcast node, the first level broadcast node is a real estate transaction node connected to the first node; the first level broadcast node receives the location After the real estate transaction request, the real estate transaction request is sent to a level 2 broadcast node, the second level broadcast node is a real estate transaction node connected to the first level broadcast node; the second level broadcast node is After receiving the real estate transaction request, the real estate transaction request is sent to a level 3 broadcast node, and the third level broadcast node is a real estate transaction node connected to the second level broadcast node; And so on, after receiving the real estate transaction request, the mth broadcast node sends the real estate transaction request to the m+1th broadcast node until each real estate transaction in the real estate transaction blockchain Before the node receives the real estate transaction request, the m+1th broadcast node is a real estate transaction node connected to the mth level broadcast node, and m is an integer greater than or equal to 1.
例如，如图2所示，若所述房产交易区块链中包含节点1至6，第一节点为节点1，与其连接的节点包含节点2、3、4，在节点2、3、4中，节点3还与节点5和6连接，因此，第一节点在区块链中广播房产交易请求时，节点1先将房产交易请求发送给节点2、3、4，由于节点2和4由于不再连接其他节点，因此，节点2和4将保存该房产交易请求且不进行转发，由于节点3连接节点5和节点6，因此，节点3将保存该房产交易请求并将该房产交易请求转发给节点5和节点6。由于节点5和节点6不再连接其他节点，因此，节点5和节点6将保存该房产交易请求，且不进行转发，通过上述方式，能够有效实现房产交易请求在区块链中的广播。可以理解的是，为了确保所有节点中的数据相同，第一节点，也即节点1也将保存该房产交易请求。For example, as shown in FIG. 2, if the real estate transaction blockchain includes nodes 1 to 6, the first node is node 1, and the node connected thereto includes nodes 2, 3, and 4, and nodes 2, 3, and 4 Node 3 is also connected to nodes 5 and 6. Therefore, when the first node broadcasts a real estate transaction request in the blockchain, node 1 first sends a real estate transaction request to nodes 2, 3, 4, since nodes 2 and 4 are not Reconnecting other nodes, therefore, nodes 2 and 4 will save the real estate transaction request and not forward, since node 3 connects node 5 and node 6, node 3 will save the real estate transaction request and forward the real estate transaction request to Node 5 and Node 6. Since node 5 and node 6 are no longer connected to other nodes, node 5 and node 6 will save the real estate transaction request and do not forward it. In the above manner, the real estate transaction request can be effectively broadcasted in the blockchain. It can be understood that in order to ensure that the data in all nodes is the same, the first node, ie node 1, will also save the real estate transaction request.
步骤S102、各个第二节点在接收到所述房产交易请求后，生成房产交易响应，并在所述房产交易区块链中广播所述房产交易响应。Step S102: After receiving the real estate transaction request, each second node generates a real estate transaction response, and broadcasts the real estate transaction response in the real estate transaction blockchain.
所述第二节点为所述多个房产交易节点中除所述第一节点之外的任意一个房产交易节点。The second node is any one of the plurality of real estate transaction nodes except the first node.
在所述第一节点广播所述房产交易请求后，任意一个接收到所述房产交易请求的房产交易节点都可以对其进行相应，为了方便描述，将响应交易的节点称为第二节点。第二节点的交易人员可以在第二节点上设置响应，且第二节点将生成房产交易响应，并在所述房产交易区块链中广播所述房产交易响应。After the first node broadcasts the real estate transaction request, any real estate transaction node that receives the real estate transaction request may respond to it. For convenience of description, the node that responds to the transaction is referred to as a second node. The trader of the second node can set a response on the second node, and the second node will generate a real estate transaction response and broadcast the real estate transaction response in the real estate transaction blockchain.
