To further illustrate the function of the present utility model, the operation flow of the blockchain system in the urban planning field is described as follows (the function of the present utility model is not limited to the position and function of the present utility model in the flow is shown in the following description):

step 1: when a user starts to start a city planning service on a node (called a task node) in the city planning field, the city planning service is decomposed into a plurality of subtasks; if the plurality of sub-tasks can be executed in parallel, the sub-tasks can be executed separately without considering the existing sequence, and if the plurality of sub-tasks need to be executed in series, the execution of the previous sub-tasks needs to be waited for and then the execution of the subsequent sub-tasks is needed.

Step 2: if the sub-task which is not executed exists, selecting one sub-task as the current sub-task; an input data index and an operation index of the current subtask are determined.

Step 3: acquiring input data from a first type of blockchain according to an input data index; determining an operation to be performed on the input data according to the operation index; the first class of blockchains has a larger block size. Preferably 1 mbyte. Other sized blocks may also be set according to desired characteristics; the first type of blockchain is used for storing data records of city planning business data.

Step 4: executing subtask corresponding operation to generate output data; outputting data requires publishing a data record on a first type of blockchain, the data record comprising at least: record generation time t0 (realized by a time stamp), record blocking maximum delay t1 (determined by the information of the business priority level such as the type of the business related to the data, the type of the owner of the data and the like according to the type of the data, the record t1 value which needs to be timely disclosed is small, the record t1 value which does not need to be timely disclosed is large), and business content; broadcasting the record in the whole network, wherein the type of the data record is content data, and the service content comprises input data, intermediate data and output data;

step 5: the nodes of the whole network are all used as block chain node equipment for storing business data in the urban planning field, and after the data acquisition submodule receives the data record broadcasted by the whole network, the data storage submodule stores the data record in a storage area of a first type of block chain arranged in the storage module;

step 6: the judging submodule judges whether the data records of the storage areas of the first type of blockchain meet the blocking condition, the current time is set to be t2, all data to be blocked are ordered in the storage areas according to the value of t=t2-t 0-t1, and the ordering with small t value is front. Then, judging 1) whether the total size of all storage data of the storage area is more than or equal to 1M (or other set sizes); judging whether 2) the t value is equal to or smaller than 0;

if the judgment 1) is true, selecting the data record according to the ordering and putting the data record into the block of the first type of block chain until the data record is not put down; if the judgment 2) is true, all the data records are put into the blocks of the first type of block chain;

the packing competition sub-module competes through a competition mechanism, and after competition is successful, the whole network broadcasts, and other block chain node devices are confirmed to become legal blocks. Each data record in the block can be input data of a subsequent task.

Step 7: and (3) after receiving the block generated in the step (6), the task node obtains an output data index, and generates an operation record comprising the input data index, the operation index and the output data index.

The input data index includes: the index of the block where the input data is located+the index of the data within the block. The input data may be null, may be 1, or may be plural.

The operation index is a predefined index of the entire blockchain system corresponding to a specific operation, the correspondence rule having a consensus among all nodes.

The output data index includes: the index of the block where the output data is located+the index of the block where the data is located.

Step 8: the task node broadcasts the operation record generated in the step 7 to the whole network;

step 9: all nodes of the whole network which receive the operation records are stored in a storage area of a second class block chain; the block size of the second type of blockchain is much smaller than the block size of the first type of blockchain, which may be, for example, 1 kbyte.

Step 10: when the capacity of the operation records in the storage area of the second class of block chains meets the blocking condition, each node packs the operation records into blocks through competition of a competition mechanism, and the blocks are broadcasted in the whole network, and after other nodes confirm, the legal blocks are obtained. The second blockchain blocking method in the step is a blockwise conditional confirmation method which is achieved by adopting a conventional means in the prior art.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
