Blockchains are generally divided into three types: public chain (Public block chain), Private chain (Private block chain), and federation chain (Consortium block chain), in addition to which there are various types of associations, such as Private chain + federation chain, federation chain + Public chain, and other combinations.
The most decentralized is the public chain represented by bitcoin and ether house, the participant who joins the public chain can read the data record on the chain, participate in transaction, compete for the accounting right of the new block, and the like, and each participant (i.e. node) can freely join and leave the network and perform related operations. Private chaining, in contrast, where the network's write rights are controlled by an organization or institution and the data read rights are specified by the organization, the private chaining may simply be a weakly centralized system with strict restrictions on participating nodes, and this type of blockchain is more suitable for use within a particular institution. The alliance chain is a block chain between a public chain and a private chain, and can realize partial decentralization, each node in the alliance chain usually has a corresponding entity mechanism or organization, and participants join the network through authorization and form a benefit-related alliance to jointly maintain the operation of the block chain.
The intelligent contracts on the blockchain are contracts which can be triggered to be executed by transactions on a blockchain system, and the intelligent contracts can be defined by the form of codes. Taking an ether house as an example, a user is supported to create and call some complex logics in an ether house network, which is the biggest challenge of the ether house in distinguishing from a bitcoin block chain technology. The intelligent contracts issued and called by users in the etherhouses are run on the virtual machines, and actually the virtual machines directly run virtual machine codes (virtual machine byte codes, hereinafter referred to as "byte codes"), and the intelligent contracts deployed on the block chains can be in the form of byte codes.
As shown in fig. 1, after Bob sends a Transaction (Transaction) containing information for creating an intelligent contract to the ethernet network, the virtual machine of node 1 may execute the Transaction and generate a corresponding contract instance, in fig. 1, "0 x6f8 …" represents the address of the contract, the data field of the Transaction may store byte codes, and the to field of the Transaction is an empty account; after the agreement is achieved between the nodes through the consensus mechanism, the contract is successfully created, and the subsequent user can call the contract.
After the contract is created, a contract account corresponding to the intelligent contract appears on the blockchain and has a specific address, and the contract code and the account storage are stored in the contract account. The behavior of the intelligent contract is controlled by the contract code, while the account storage of the intelligent contract preserves the state of the contract, in other words, the intelligent contract causes a virtual account to be generated on the blockchain that contains the contract code and the account storage.
As mentioned above, the data field containing the transaction that created the smart contract holds what may be the bytecode for the smart contract, which is made up of a series of bytes, each of which may identify an operation. Based on the multiple considerations of development efficiency, readability and the like, a developer can select a high-level language to write intelligent contract codes instead of directly writing byte codes. For example, in a high-level language such as Solidity, Serpent, LLL, etc., for the intelligent contract code written in the high-level language, it can be compiled by a compiler to generate a bytecode that can be deployed on a blockchain.
Taking the Solidity language as an example, the contract written by the method is similar to the class in the object-oriented programming language, and various members including state variables, functions, function modifiers, events and the like can be declared in one contract. A state variable is a value permanently stored in the account storage of a smart contract that is used to save the state of the contract.
Generally, when an intelligent contract is deployed in a blockchain, the storage state corresponding to the state variable in the contract code of the intelligent contract is plaintext, and anyone can see the state without setting and capability of privacy protection.
As shown in fig. 2, still taking the ethernet lane as an example, after Bob sends a transaction containing the information of invoking the intelligent contract to the ethernet lane network, the virtual machine of node 1 may execute the transaction and generate the corresponding contract instance. The from field of the transaction in fig. 2 is the address of the account from which the intelligent contract was initiated, the "0 x …" in the to field represents the address of the intelligent contract that was invoked, the value field is the value in the etherhouse in the tai-currency, and the data field of the transaction holds the method and parameters for invoking the intelligent contract. After invoking the smart contract, the value of value may change, and a subsequent participant may view the current value of value through a blockchain node (e.g., node 6 in fig. 2).
The intelligent contracts can be independently executed at each node in the blockchain network in a specified mode, all execution records and data are stored on the blockchain, and therefore when the transaction is completed, transaction certificates which cannot be tampered and cannot be lost are stored on the blockchain.
In the embodiment of the application, the barcode label can be a one-dimensional barcode or a two-dimensional barcode. The bar code label is used for generating a bar code label for each product to identify the digital identity of the product, so that one object and one code are realized. The life cycle of the bar code label comprises application, verification, code generation, downloading, decryption, printing, transportation, signing and activation, and the main body in the industry chain comprises an enterprise requiring codes, a code generation worker, a verifier, a code generation system, a printing factory and a user purchasing bar code label products. In an embodiment of the present application, the life cycle of the barcode tag may be sequentially:

monitoring a code package downloading event by a printing factory, executing code package downloading operation, including acquiring a ciphertext, decrypting by using a private key corresponding to a public key to acquire a downloading link and a decryption key, downloading a code package through the downloading link, decrypting the code package through the decryption key, and issuing downloading information related to code package downloading to a block chain for storing a certificate; the decrypted code packet comprises printing information, such as printing quantity and printing type, and the printing information is issued to the block chain for storing the certificate; after printing is finished by a printing factory, carrying out delivery operation, including express delivery of the produced bar code label to an enterprise, and issuing delivery information related to delivery to a block chain for storage;
the enterprise side receives the bar code label, executes the goods receiving operation and issues the goods receiving information related to the goods receiving to the block chain for storing the certificate; when the enterprise uses the bar code label, activating operation is required to be executed, and activating information related to activation is issued to the block chain for storing the certificate;
a user side purchases a product with a bar code label, executes code scanning operation, and can display related certificate of the bar code label when executing the code scanning operation, so that the user can know the whole life cycle of the bar code label in detail, and code scanning information related to code scanning is issued to a block chain for certificate storage; it should be noted that the operation information related to the operation transaction to be commonly recognized may include time information of the execution of the operation transaction, and the like.
The embodiment provides a barcode tag life cycle management method based on a block chain, which is applied to a block chain node, and fig. 3 is a first flowchart of the barcode tag life cycle management method based on the block chain according to the embodiment of the present application, and as shown in fig. 3, the flowchart includes the following steps:
step S301, acquiring an operation notification event aiming at the current life cycle stage of the barcode label, and constructing an operation transaction according to the operation notification event;
it should be noted that the operation notification event in the current life cycle stage of the barcode label may be any one of an audit notification event, a code generation notification event, a printing notification event, a code package request notification event, a code package download notification event, and the like; the operation transaction may be any one of an audit operation related to an audit notification event, a code generation operation related to a code generation notification event, a printing operation related to a print notification event, a code package request operation related to a code package request notification event, a download code package request operation related to a download code package notification event, and the like.
Step S302, issuing the operation information which is identified commonly and is related to the operation transaction to a block chain for storing evidence according to the operation transaction;
the operation information related to the operation transaction may be any one of an audit result related to an audit operation, code generation information related to a code generation operation, and the like.
Step S303, if the operation information is stored in the block chain, generating an operation notification event related to the next life cycle stage of the bar code label according to the current life cycle stage of the bar code label related to the operation transaction;
for example, if the current life cycle stage of the barcode label is an auditing operation stage of an auditor, an operation notification event related to the next life cycle stage of the barcode label is generated, and the operation notification event is a code generation operation event;
it should be noted that, in one case, the operation processing may be performed on the operation of the barcode label on line by the party related to the barcode label, and then the operation information (which may be understood as the operation result) generated by the processing is issued to the blockchain for storage. In this case, after receiving the operation transaction for the barcode label, the block link point may issue the operation information of the identified operation transaction to the block link for deposit in response to the operation transaction;
in another case, the operation processing may be performed on the barcode label by deploying an intelligent contract on the blockchain, which is illustrated by taking the blockchain as an example of a federation chain, and the members of the federation chain may deploy an intelligent contract on the federation chain for performing operation processing on the barcode label and declare the barcode label processing logic in the intelligent contract. After the development of the intelligent contract is completed, the members of the federation chain can issue the intelligent contract to the federation chain through the node devices in the federation chain, and the intelligent contract is collected to the distributed database of the federation chain after the intelligent contract is identified by the member node devices specified by the part in the federation chain (for example, a plurality of authority node devices specified in the federation chain). Subsequently, the user may submit a transaction (transaction) to the intelligent contract included in the federation chain through the access node device to initiate a contract invocation for the intelligent contract, triggering execution of relevant business logic on the federation chain. Based on the deployment of the intelligent contract, the operation transaction is a transaction (including the address of the invoked intelligent contract) for invoking the intelligent contract, the operation information aiming at the barcode label related to the operation transaction, and the operation information (which can be understood as an operation result) generated by invoking the intelligent contract and executing operation processing aiming at the barcode label; after receiving the operation transaction aiming at the bar code label, the blockchain node calls a bar code label processing logic declared in an intelligent contract issued on the blockchain, executes operation processing on the bar code label, and issues operation information generated by executing the operation processing on the bar code label to the blockchain for storage;
through the above steps S301 to S302, based on the barcode tag life cycle stage, after the operation transaction is completed by the front party, the operation information related to the operation transaction is issued to the blockchain for evidence storage, and generating an operation notification event related to the next life cycle stage of the bar code label under the condition that the operation information is stored on the blockchain, so as to ensure that the operation information related to the operation transaction is successfully stored on the blockchain in the front, furthermore, when the bar code label is abnormal, the responsibility party is confirmed according to the deposit certificate on the block chain based on the non-falsification of the block chain, the problem that the authority of the main body in the industrial chain is difficult to be clear under the condition that the bar code label is abnormal in the related technology is solved, interaction among different main bodies is realized through an event mechanism based on the block chain, and self-certification clearing of enterprises can be helped based on the non-tampering and traceable characteristics of the block chain.
In some embodiments, fig. 4 is a flowchart of a second method for managing a life cycle of a barcode tag based on a blockchain according to an embodiment of the present application, where as shown in fig. 4, before issuing operation information related to an operation transaction, which is identified by a consensus, to the blockchain for verification, the method includes the following steps:
step S401, verifying the transaction address of the operation transaction; if the transaction address is matched with the preset address of the block chain link point, issuing the identified operation information related to the operation transaction to the block chain for storing the certificate according to the operation transaction;
the preset address is written in the intelligent contract, and before a certain party issues operation information related to operation transaction to the block chain for evidence storage, the intelligent contract performs authority verification, namely the transaction address of the operation transaction is matched with the preset address, so that whether the party has authority is determined, and the reliability of the block chain evidence storage is further ensured.
In some embodiments, if the acquired operation notification event includes contract signing related information for the barcode tag, the agreed operation information related to the operation transaction includes a hash value obtained by hash conversion of the contract data and a path index stored in the contract data;
for example, in the application stage of the barcode label, after a contract for the barcode label is made between an enterprise side and a barcode generator side, the node corresponding to the barcode generator side processes the identical data by using a hash algorithm, and issues the generated hash value and a path index of a storage location of the contract data to a blockchain for storage, wherein the contract data may be a carrier carrying contract content, such as an image related to the contract, and the path index stored in the contract data may be understood as a path stored in the image related to the contract.
In some embodiments, if the current life cycle phase is the life cycle phase of executing the code packet request for the barcode label; the operation notification event related to the next life cycle stage of the bar code label comprises a code packet request public key;
the code packet requests a public key, namely the public key, which is a non-secret half of a key pair used together with the private key, and if the public key is used for encrypting data, the private key is required to be used for decryption; after monitoring the printing notification event, the printing factory related to the bar code label executes the code packet request transaction, the operation information related to the operation transaction is the code packet request information, the code packet request event is generated after the code packet request information is stored and verified on the block chain, and the code packet request event comprises a public key, so that the related party at the next life cycle stage of the bar code label can generate a ciphertext according to the public key, and the printing factory decrypts the content behind the ciphertext according to the private key, so as to ensure the safety of information transmission between the printing factory and the printing factory.
In some embodiments, if an operation notification event containing a code packet request public key is acquired, encrypting a download index for a barcode tag based on the code packet request public key to generate a ciphertext corresponding to the download index, wherein the operation notification event related to the next life cycle stage of the barcode tag contains the ciphertext;
it should be noted that the download index of the barcode label can be encrypted through the public key, and in order to further ensure the security, the code packet of the barcode label can be encrypted; wherein, the code packet contains printing information, such as printing quantity and printing type; it can be understood that the download index of the barcode label is the download index of the code packet, and the code packet corresponds to the decryption key, so that after the code packet is downloaded through the download index, the code packet can be opened according to the decryption key, and further, both the download index and the decryption key can be encrypted through the public key to generate the ciphertext of the download index and the decryption key, so as to improve the security of the data related to the code packet.
