The method provided by the embodiment of the invention can be applied to the condition of processing the transaction information in the transaction event. As shown in fig. 1b, the method provided by the embodiment of the present invention includes:
s110: acquiring transaction information based on the first block link node and synchronizing the transaction information to at least one second block link node; wherein the transaction information includes current transaction data and a current transaction status.
In this step, in many nodes in the block chain distributed system, namely, block chain nodes, the block chain nodes can be understood as devices installed with bitcoin purses. Wherein the second block link point is distinct from the first block link node.
In this step, the transaction information may be information in a transaction form, the transaction form may be an order, bill, or asset form, and the like, and the information in the transaction form may include current transaction data and current transaction status.
The client side can operate in an interface of the client side, so that the client side generates a transaction list, and the client side sends information in the transaction list to the first block chain node through the adaptation layer corresponding to the first block chain node. The first block link point acquires transaction information, wherein the transaction information comprises transaction data and a transaction state. The transaction state refers to the state of the current transaction, and may be auditing, settlement or the like.
After the first block link node acquires the transaction information, the transaction information may be synchronized with other block link nodes through a Point-to-Point (P2P) Protocol, that is, synchronized with at least one second block link node. Wherein a first block link point may be deployed within one tissue and a second block link point deployed within another tissue.
S120: and when receiving the transaction information, the second blockchain node sends an event notification to a corresponding adaptation layer, wherein the transaction information is carried in the event notification.
In this step, when each second block link node receives the transaction information, an event notification is sent to the adaptation layer corresponding to the second block link node, where the event notification carries the transaction information, that is, the event notification carries the current transaction data and the current transaction state. The adaptation layer may be a bottom layer interaction layer for linking the blockchain node and the client, and may be deployed on different devices from the blockchain node or on the same device.

For example, when the state field is "10", the transaction state may be characterized as audit, and when the state field is "20", the transaction state may be characterized as settlement. The corresponding relation between the transaction state and the response interface can be changed by a user in a configuration center. The configuration center may be deployed on one device with the adaptation layer or may be deployed on a different device with the adaptation layer. The configuration center can understand that the configuration items of the application and the data can be stored, the configuration information can be changed through the configuration center, and the corresponding relation between the transaction state and the response interface can be changed, so that different processing can be carried out on the transaction data in the transaction event according to the requirement, the problem that the code is not changed when the transaction event configuration response interface is changed in the prior art is solved, the configuration efficiency is improved, and the cost is reduced.

For example, the content of the configuration center may be in the form of:
for the http interface: the content of the configuration center is as follows:
{“10”:http://hostname:port/event1，
“20”:http://hostname:port/event2”}
where "10 and" 20 "may characterize the transaction state, the following corresponding http:// hostname: port/event1 or http:// hostname: port/event2 may be the url of the response interface.
For the rpc interface: the content of the configuration center configuration may be:
{“10”:{“serverName”:com.XXX.service.OrderService”,”method”:”addOrder”},
“20”:”{“serverName”:com.XXX.service.OrderService”,“method”:“cancelOrder”}}
where "10 and" 20 "may characterize the transaction status, {" server name ": com.xxx.service.orderservice", "method": addOrder "} or {" server name ": com.xxx.service.orderservice", "method": cancel order "} is the name of the service, respectively, where the rpc interface may be located by the name of the service.
For asynchronous message interfaces, the content of the configuration center configuration may be:
{“10”:{“topicName”:“addOrder”},
“20”:”{“topicName”:“cancelOrder”}}
wherein "10 and" 20 "may characterize the transaction status, and {" topicName ": addOrder" } or "{" topicName ": cancel order" } "are topic names, respectively, by which the asynchronous message interface may be located.

The user can operate the transaction order in the interface of the client, the client obtains the execution operation of the transaction order, and the execution operation can be settlement operation, auditing operation and the like. For example, when the user clicks a settlement button in the client interface, the client obtains a settlement operation for the transaction ticket, and determines that the current transaction state is settlement according to the execution operation, thereby determining the corresponding state field.
S240: based on the client corresponding to the first block chain link point, calling an adaptation layer corresponding to the first block chain link point, and based on the called adaptation layer, writing transaction information into the first block chain link point, wherein the transaction information comprises current transaction data and a state field representing a current transaction state.
