s808, the client 1 sends the collected intelligent contract confirmation deployment endorsement result to the sequencing node 4, and generates a block after finishing sequencing consensus;
s809 verifying the block pulled by the node 5 to the sorting node 4 and verifying;
s810 the contract state monitoring module monitors that the contract state is updated (actually, it detects that the Sequence has changed, for the purpose of generalization of system design, the initial setting of the Sequence is 0, the contract is first deployed and the parameter is 1, and the Sequence has changed, thus triggering the contract state monitoring mechanism of the contract daemon module 23), the contract daemon module 23 is notified when the contract deployment is allowed, the contract daemon module 23 checks the contract state, finds that the contract container is not started, and then acquires the contract image information, starts the contract container (the process uses the unique contract hash value for retrieval), and registers the operation record of the contract container in the contract daemon module 23.
At this point, the contract may begin normal transaction execution.
Referring to fig. 9, the intelligent contract upgrading process is as follows:
s901, the client 1 packages the updated intelligent contract codes;
s902, the client 1 assembles an intelligent contract installation transaction request by using a new contract package obtained by packaging in S901, and sends the intelligent contract installation transaction request to the endorsement node 2, and the endorsement node 2 calculates a new unique hash value according to the contract name and the contract package content and returns the new unique hash value to the client 1;
s904, the client 1 initiates the contract deployment vote to the endorsement node 2 by using the new contract unique hash value obtained in S902, and it is noted that Sequence +1 needs to be specified here, that is, an upgrade operation is performed. Generally, a general organization can deploy the intelligent contract only by agreeing, so that more than half of endorsement nodes 2 need to be sent with a voting request, and the endorsement nodes 2 return voting results to the client 1;
s905 the client 1 sends the collected voting endorsement results to the sorting node 4, and generates a block after finishing sorting consensus;
s906 the verification node 5 pulls the block to the sorting node 4 and verifies the block, and finally persists the block;
s907 the client 1 sends a contract deployment confirmation request to the endorsement node 2, and the endorsement node 2 returns an endorsement result for confirming the contract deployment transaction;
s908, the client 1 sends the collected intelligent contract confirmation deployment endorsement result to the sequencing node 4, and generates a block after finishing sequencing consensus;
s909 verifying node 5 pulling the block to sorting node 4 and verifying;
s910, when monitoring that the contract state is updated (Sequence changes by + 1), the contract state monitoring module triggers the conditional lock module 252 in the transaction cache module 25, and the transaction starts to stop being transmitted to the intelligent contract 3;
the S911 contract daemon module 23 monitors the contract state update, and finds the state record and the container running record corresponding to the contract name;
s912, the contract daemon module 23 determines whether the Sequence is increased by 1, compares the hash of the contract whose state is updated with the hash of the current contract running container, and sets the state of the contract running container to a stoppable state if the hash of the current contract running container is not consistent with the hash of the current contract running container;
s913 detecting that the container is in a stoppable state by the container state machine in the contract daemon module 23, and detecting whether there is an unfinished transaction in the transaction message list 251;
s914 has no incomplete transaction, the container state machine in the contract daemon module 23 stops running the current contract running container, and releases the conditional lock in the conditional lock module 252, and sets the contract container state as bootable dynamic;
the container state machine in the S915 contract daemon module 23 detects that the contract container is bootable, and then performs the startup of the contract container by using the mirror image corresponding to the new contract hash constructed in S903.
The transaction in the transaction cache module 25 can be normally transmitted to the intelligent contract 3 for execution, and the contract container is an updated and upgraded contract container. When the contract is automatically upgraded, the normal operation of system transaction is not influenced, and in the whole upgrading process, the contract state is quickly switched, so that the upgrading is efficient and quick.
After the contract is upgraded, the new and old contract data can be compatible for use without migration, and for this reason, the present invention further provides a dynamic data structure based on reflection technology, and details of the technical scheme are described in detail below.
Reflection, which is to dynamically acquire information about an object, dynamically executes the method of the object, because it is sometimes unknown during operation what type and what attributes and methods the object is specifically. Such as heterogeneous data for new and old contracts, data for new contracts does not know the type and properties of the old contract data objects, and so on. The specific steps of the heterogeneous data compatible technical scheme are as follows:
1. for a data structure in a contract, mapping the data structure into an intermediate data structure through a reflection technology, wherein each field in the contract data structure is converted into a piece of record data in the intermediate data structure;
2. for each field record, splicing key attributes (field names, types, lengths and the like) in the intermediate data structure to calculate hash;
3. taking each hash obtained by calculation in the step 2 as a key value of a world state of the blockchain, taking a real original value of the field as a corresponding value of the key, and storing the value into a blockchain account book (the contract data is subjected to data storage in the mode);
4. when accessing heterogeneous data, similarly, a reflection method is adopted to convert the intermediate data structure of the new data structure, and the hash value of the field to be accessed is calculated according to the step 2 to obtain the account book key value of the field;
5. and (4) accessing the block chain account book by using the key value obtained in the step (4) to obtain the value of the field stored on the block chain, and storing new field data in the same way as in the steps (2) and (3).
6. By means of the reflection conversion intermediate dynamic data structure and the mode of storing the book (k, v) pair forms, seamless connection and smooth compatibility of heterogeneous data can be achieved, and the method is shown in fig. 10.
Therefore, the block chain system provided by the invention can access and update new and old contract data under the normal operation of the system, and can automatically support heterogeneous data compatibility while upgrading the contract, thereby greatly reducing the cost of data migration.
The invention has the beneficial technical effects that: the intelligent contract life cycle design mode is efficient and rapid, automatic upgrading of intelligent contracts in a containerized deployment mode is achieved through a contract daemon process, contract state updating detection and a contract container state machine, and normal transaction execution is not affected. The middle dynamic data structure based on the reflection technology is utilized to realize the compatible use of heterogeneous data, so that new and old contract data can be accessed and read compatibly without additional migration.
