Description
Technical Field
The invention belongs to the technical field of industrial control, and particularly relates to a business object life cycle management and tracing method and device based on a blockchain.
Background
Business object information under the micro-business architecture is recorded and stored in each business system or service in a scattered and isolated manner, and is lack of correlation, so that the problem of information island is serious, and in addition, the problems of information asymmetry, information counterfeiting, privacy infringement and the like are caused by inherent barriers among enterprises, so that the whole life cycle of the business object and the circulation condition of each intermediate link are difficult to trace.
Because of collision and distrust of interests naturally occurring in departments and enterprises, trust or contract relation is always slow and difficult to build when any two parties interact, so that the phenomenon of 'data wall' in and among enterprises is very common, and the problems of isolated information, complicated information circulation, low information transparency and the like are caused.
In the manufacturing industry, from planning to processing to produce final products, the complexity may go through tens or even hundreds of steps, and each link of the intermediate circulation contains a large amount of business information. The current micro-service architecture is large, and for a system with complex business, the system like an enterprise interior SCM, MES, QMS is often further split into a plurality of micro-services to cope with the change of the complex business, so that the system can usually operate with tens of hundreds of micro-services behind the informatization, the digitalization and the intellectualization of the enterprise. Behind so many services are hundreds of business objects, and it is very difficult to effectively retrospectively manage these objects.
Through realizing the whole life cycle management and the traceability of the business information, the production process can be effectively analyzed in enterprises, each configuration detail in the production process is improved and corrected, and the supply chain, the production and the sales among enterprises can be accurately butted and the industrial collaborative capability is improved by combining intelligent services.
In order to implement life cycle traceability management of business objects, the common solutions in the industry are: the objects are labeled, the association between the objects is established, then the label objects and the association relationship between the objects are stored in a centralized mode, and finally the objects are displayed in a foreground system. The disadvantage of this solution is that the service object information and association relation need to be captured from each service system or service, but the selection and frequency of the extraction timing are limited, and the life cycle information of each stage of the object cannot be completely displayed in real time; meanwhile, the business object information is scattered in each business system in the whole flow, and the data information of each related stakeholder cannot be synchronously updated in real time due to the opaque information, so that the possibility of tampering data exists, and the credibility of the data is greatly reduced;
in view of this, there is a need for a method for managing and tracing the lifecycle of a service object by using a blockchain technique.

The invention builds the alliance chain as the blockchain network based on the open source framework, has the advantages of low operation and maintenance cost, high transaction processing speed and good expansibility compared with the public chain, and is suitable for being applied to industrial enterprises. The blockchain network is composed of a plurality of blockchain link points, and typically, at least one node is added to the blockchain network by an enterprise in a federation, such as a raw material supplier, a manufacturing enterprise, a logistics distribution enterprise, and the like. Each newly added blockchain node needs to be registered and authenticated in a CA authentication center, unique blockchain node ID and a blockchain node key pair are distributed by the authentication center, and meanwhile, each blockchain node maintains public key information of all the blockchain nodes and the under-jurisdiction service nodes.
The service node also needs to register and authenticate in the CA authentication center, and the authentication center distributes unique service node ID, block chain node ID and service node key pair. A typical service node corresponds to a blockchain node, but considering that a service system may be composed of a plurality of micro services under a micro service architecture, the present invention supports a plurality of service nodes under the blockchain node. After the service node is registered and authenticated, the obtained service node ID, the blockchain node ID and the service node key pair are configured in the self service according to the agreed rule.
Specifically, in the step S2, registration authentication is performed in the CA authentication center, the authentication center distributes a unique service node ID, a blockchain node key pair, and a service node key pair, and entering the corresponding service node after the authentication is passed includes:
registering and authenticating each newly added blockchain node, distributing unique blockchain node ID and blockchain node key pairs by an authentication center, and maintaining public key information of all blockchain nodes and under-jurisdiction service nodes by each blockchain node;
registering and authenticating the service node in a CA authentication center, and distributing unique service node ID, block chain node ID and service node key pair by the authentication center;
after the service node registers and authenticates, the obtained service node ID, block chain node ID and service node key pair are configured in the self service according to the agreed rule.
As shown in fig. 3, in the step S3, when the service object is changed or transformed, the service node performs information construction and generates tracing information and a signature, and determines whether the constructed information is key information, where the constructed information includes key information and non-key information, and the key information includes an object ID, a trigger action, a summary, a transformed object ID, and a non-key information Hash value; the non-critical information includes operators, object descriptions, attachments, etc.
It will be appreciated by those skilled in the art that in order to fully record the life cycle information of the object and not to contain unnecessary information, the service node performs information construction when the object is changed and transformed, wherein the information constructed by the change includes operations such as adding, modifying, deleting, etc., the transformation such as transforming the raw material a into the semi-finished product B, etc., the key information M includes, but is not limited to, an object ID, a trigger action, a abstract, a transformed object ID, a non-key information Hash value, and the non-key information N may be an operator, an object description, an attachment, etc. The object ID is maintained by the mark analysis system, and each service node uniformly acquires the object ID from the mark analysis system.
The sign analysis system realizes flexible differentiation and information circulation management of the whole network resources by giving each entity or virtual object unique identity code and carrying out quick positioning and information inquiry. It is also possible for the service node to invoke the smart contract at some point in time. Intelligent contracts are codes running on blockchains, and we can write business logic in the contracts and define clear functional interfaces for callers, such as automatic generation of shipping notices when shipping in logistics, etc.
The intelligent contract provides a service automation processing capability, in the step S3, when a service object is changed or converted, a service node builds information and generates tracing information and a signature, and judges whether the built information is intelligent contract information or not, wherein the intelligent contract information comprises contract addresses and contract parameters. When a caller calls a contract, an executor on the blockchain can automatically execute a contract code on the blockchain and store an execution result and an execution record on the blockchain, and the blockchain ensures that the intelligent contract cannot be tampered, so that the contract content and the execution result cannot be tampered, and the record cannot be tampered when the caller calls each time. When constructing the contract call information, key information such as contract address and contract parameters should be included.
The signed information is a relatively general action that can be invoked by an encapsulated SDK to various service nodes. The SDK should include the ability to sign information using the service node private key, upload critical information to the blockchain node, upload non-critical information to off-chain storage. The separate storage of information here is due to the relatively expensive and low performance of storing information on the blockchain, which can affect the concurrency and throughput of the system if the data are all put together, so that only non-critical data Hash values are stored on the blockchain, while non-critical information is stored in an off-chain database, such as an elastomer search, which is very fast to query. In addition, the SDK automatically fills in some necessary key information, such as record ID, service node ID, blockchain node ID, and time stamp.
Specifically, when the service object is changed or transformed, in the step S3, the service node performs information construction, generates traceability information and a signature, sends the key information to the blockchain network to form a blockrecord, and sends the non-key information to the out-of-chain storage further includes:
after the key information generated by the service node is sent to a preset block chain node, the block chain node verifies whether the information is legal or not in a verification information signature mode, if so, whether the verification information repeatedly appears is further checked, if not, the verification information is added into an information pool queue for caching and broadcasting to other block chain nodes known by the node, if not, the key information is directly discarded, and if not, the other block chain nodes receive the broadcast information and then are added into the information pool queue after verification.
Specifically, the step S4 of obtaining the block record and constructing a new block through a consensus mechanism and forming a trusted block uplink by using an encryption algorithm includes:
collecting the block information and broadcasting the block information among the block chain nodes, acquiring a current highest block from a block chain network by a leader node, generating a new empty block based on the highest block and generating a new block, and adopting a consensus algorithm to agree on a new block record when 2 xf+1 non-malicious nodes work normally;
the leader node takes out the preset quantity of information from the information pool according to the first-in first-out principle, inserts the information into a new block, signs the information by adopting a private key, and then sends the information to other block chain nodes, the other block chain nodes sign the received new block to verify whether the current block record is true and effective, and through broadcasting a verification result, an executor is adopted to execute contract instruction operation on intelligent contracts in the block, and the execution result is stored;
and collecting full 2 xf+1 nodes for verifying that the new block is added into a local block chain through the node broadcasting information, updating the content related to the block height and the mapping table of the block hash, deleting the information record of the new block from the information pool, switching leader nodes according to preset time, and iteratively updating the new block and the block record, wherein f is the number of fault nodes, the total number of nodes is 3 xf+1, and compared with meaningless random hash value calculation, the optimized consensus mechanism is more energy-saving, environment-friendly and efficient.
Because of the multi-node and the consensus mechanism of the block chain, the data falling onto the block chain is hardly tampered, so that the safety and the reliability of the data are ensured, which is difficult to reach by the traditional traceability management method. In addition, blockchains also have smart contracts that can handle transactions well, which is also not possible with traditional traceback methods.
Those skilled in the art will appreciate that after the key information generated by the service node is sent to the specified blockchain node, the blockchain node verifies whether the information is legal by verifying the signature of the information. If the information is legal, whether the information is repeatedly appeared or not is further checked, and if the information is not appeared, the information is added into an information pool queue to be cached and broadcast to other block chain nodes known to the node. If the information is illegal or repeated, the information is directly discarded. After receiving the broadcast information, other block chain nodes also need to be verified and then added into own information pool queues. After a period of information collection and broadcasting, the block chain system enters a common identification block link. In a blockchain system, consensus is a process that each node agrees on the execution result of a transaction, and in general, the essence of this mechanism is how to agree on the update of most people. The PBFT (Practical Byzantine Fault Tolerance) consensus algorithm adopted by the method can reach consensus in the bad (such as fake message) scene of a few nodes, adopts cryptographic algorithms such as signature, signature verification, hash and the like to ensure tamper resistance, anti-counterfeiting and non-repudiation in the message transmission process, optimizes the foreigner work, reduces the complexity of the Bayesian fault-tolerant algorithm from exponential level to polynomial level, and can reach agreement as long as no less than (2 x f+1) non-malicious nodes work normally in a system consisting of (3 x f+1) nodes, such as: a 7-node system allows 2 nodes to have a bayer error. In each round of consensus process, only one leader is provided, and in order to prevent the leader from forging the block, after each round of PBFT consensus, the leader is switched. In a round of block identification process, the leader node acquires the current highest block from the block chain network, generates a new empty block based on the highest block, sets a new block father hash as the highest block hash, and sets a time stamp as the current time. After generating a new block, the leader node takes out a certain amount of information from the information pool according to the first-in first-out principle, inserts the information into the new block, signs the information with the private key of the leader node, and sends the information to other blockchain nodes, and the other blockchain nodes conduct signature verification on the received new block and broadcast verification results. The intelligent contract record in the block is executed once by the executor and the execution result is stored. And collecting the nodes meeting the requirement of 2 xf+1 verification that the new block is added into the local block chain through broadcasting information, updating the contents such as a mapping table of the block height and the block hash, and then deleting the information record of the new block from the information pool.
The presentation layer constructed in this embodiment may be constructed from a variety of front end frameworks including, but not limited to, exact, vue, etc. When the system is traced, any node on the object ID deblocking chain network searches the block record related to the ID, and simultaneously queries non-key information according to non-key data Hash value out-of-chain storage in the block record, and all the obtained information is constructed into a link tree cache according to a time stamp. When a user inquires, the system displays life cycle information of the business object in real time, including when the business object is born, how to change the business object, and how to convert the business object into other objects. On the other hand, the presentation layer also provides the functions of inquiring intelligent contract rules, executing contract results and executing records by the user. In addition, the display layer generates two-dimensional codes, bar codes, RFID codes and the like through the object ID, and supports mobile phones, PDAs or other code scanning devices to inquire or trace through the code scanning.

The information on the blockchain is publicly visible, and all participants can trace back the full life cycle information of the business object.
