[0048] Reference Figure 1 FIG. 1 is a flow chart of a method for managing corporate bank accounts based on a supply chain platform according to an embodiment of the present invention. In this embodiment, the method for managing corporate bank accounts based on a supply chain platform includes:

[0049] The enterprise bank account management method based on the supply chain platform comprises the following steps:

[0050] Asymmetrically encrypt the pre-acquired account information, and perform transaction packaging on the asymmetrically encrypted account information to obtain the corporate bank's transaction;

[0051] Broadcasting the transaction to a pre-built blockchain network;

[0052] Using the network nodes in the blockchain network to perform signature verification on each of the transactions, when the transaction passes the signature verification, packaging all transactions that pass the signature verification into a block;

[0053] Generate a consensus node of the network nodes;

[0054] The consensus node is used to process the block on the chain to obtain an updated blockchain network.

[0055] In a preferred embodiment of the present invention, the enterprise bank account management method based on the supply chain platform includes:

[0056] S1. Asymmetrically encrypt the account information acquired in advance, and perform transaction packaging on the asymmetrically encrypted account information to obtain the corporate bank's transaction.

[0057] In the embodiment of the present invention, the asymmetric encryption of the pre-acquired account information includes:

[0058] Generate a key pair of pre-acquired account information;

[0059] The pre-acquired account information is encrypted using the public key in the key pair to obtain a ciphertext of the pre-acquired account information.

[0060] In detail, the asymmetric encryption of the pre-acquired account information may be performed using the RSA (Rivest-Shamir-Adleman) algorithm, which is a common and secure asymmetric encryption algorithm that uses a pair of keys (a public key and a private key) to encrypt and decrypt data.

[0061] In detail, for each customer or account, a key pair needs to be generated, including a public key and a private key, where the public key is used to encrypt data and the private key is used to decrypt data. These key pairs can be generated when the customer registers or the account is created and associated with the corresponding account information.

[0062] In detail, the pre-acquired account information includes: the name of the account holder, account number, balance, etc., which are accurately acquired and prepared for encryption.

[0063] In detail, once the key pair is generated, the public key can be used to encrypt account information. The encryption process converts the account information into unreadable ciphertext. Only the entity holding the corresponding private key can decrypt and read the original account information.

[0064] In detail, through the above steps, the account information obtained in advance will be processed through secure asymmetric encryption, ensuring the confidentiality and security of the account information during transmission and storage.

[0065] In detail, the asymmetrically encrypted account information is packaged for transactions to obtain corporate bank transactions, including:

[0066] Decrypting the asymmetrically encrypted account information using the private key in the key pair to obtain the plain text account data of the corporate bank;

[0067] Constructing transaction data of the transaction to be constructed of the corporate bank according to the plain text account data and preset transaction requirements;

[0068] The transaction data is digitally signed, and the digitally signed transaction data is packaged into a transaction package of the corporate bank.

[0069] In detail, the asymmetrically encrypted account information refers to the account information previously encrypted with a public key, and the asymmetrically encrypted account information is decrypted using a corresponding private key to obtain the original plaintext account data.

[0070] Furthermore, by using the private key to decrypt the account information, the account information can be restored to readable plaintext data when needed to facilitate subsequent transaction processing.

[0071] In detail, constructing the transaction data of the corporate bank's transaction to be constructed based on the plaintext account data and preset transaction requirements means combining the decrypted account information with the required transaction type, transaction amount, target account and other information to construct a data structure that meets the corporate bank transaction requirements, and create a transaction object or data model that includes all necessary transaction information.

[0072] Furthermore, the constructed transaction data structure is serialized into a transmittable format, such as JSON, XML, etc. This can ensure the consistency and integrity of the transaction data during transmission.

[0073] In detail, the transaction data is digitally signed using a private key to ensure its authenticity and integrity, and the signature result is sent together with the transaction data to the corporate bank for verification.

[0074] In detail, the signed transaction data is packaged together with its additional information (such as certificates, timestamps, etc.) into a complete transaction package. This message includes the details of the transaction, such as the sender, receiver, amount, etc.

[0075] S2. Broadcast the transaction to a pre-built blockchain network.

[0076] In an embodiment of the present invention, broadcasting the transaction to a pre-built blockchain network includes:

[0077] Determine the communication protocol of the pre-built blockchain network;

[0078] Establishing a broadcast connection with a target node in the blockchain network according to the communication protocol;

[0079] The transaction is broadcast to the target node according to the established broadcast connection, and the transaction information is propagated using the target node.

[0080] In detail, select one or more target nodes, which will become the recipients of the transaction. You can choose nodes that are directly connected to you or other important nodes in the network.

[0081] Furthermore, through the communication protocol of the blockchain network, a connection is established with the selected target nodes, so that transaction messages can be sent to these nodes.

[0082] In detail, broadcasting the transaction to the target node according to the established broadcast connection and using the target node to propagate the transaction information refers to using the broadcast mechanism of the blockchain network to broadcast the transaction message to the selected node. In other words, it means sending the transaction message to the node so that the node further propagates the message to their adjacent nodes.

[0083] Furthermore, ensuring that the transaction message is successfully propagated to other nodes in the network may require waiting for a period of time so that enough nodes receive and forward the transaction message.

[0084] S3. Use the network nodes in the blockchain network to perform signature verification on each of the transactions. When the transaction passes the signature verification, package all transactions that pass the signature verification into a block.

[0085] In an embodiment of the present invention, the method of using a network node in the blockchain network to perform signature verification on each transaction includes:

[0086] Determine a transaction to be verified based on transactions received by a network node in the blockchain network, and extract a digital signature from the transaction to be verified;

[0087] Obtain the public key corresponding to the exchange from the sender corresponding to the exchange;

[0088] The digital signature is verified using the public key and the transaction.

[0089] In detail, a node in the blockchain network receives a transaction to be verified and extracts a digital signature portion from the received transaction.

[0090] Furthermore, obtaining the public key corresponding to the exchange from the sender corresponding to the exchange refers to extracting specific fields or information of the public key from the transaction data.

[0091] In detail, using the obtained public key and transaction data, the digital signature is verified to ensure that the transaction data has not been tampered with and is indeed signed by the sender.

[0092] In the embodiment of the present invention, when the transaction passes the signature verification, all the signature-verified transactions are packaged into a block, including:

[0093] Calculate the hash values ​​of the transactions verified by the signature one by one;

[0094] Generate a transaction list of transactions verified by signature according to the hash value;

[0095] The transactions are targeted according to the handling fees corresponding to the exchanges in the transaction list, and the selected transactions are packaged into blocks.

[0096] For example, calculating the hash value of the signature-verified transactions one by one refers to performing a hash operation on each signature-verified transaction to obtain a unique identifier of a fixed length, wherein a hash function (such as SHA-256) is applied to each signature-verified transaction to generate a unique hash value.

[0097] For example, generating the transaction list of the transactions verified by the signature according to the hash value means using a data structure (such as a list, a dictionary, etc.) to store transactions and their hash values ​​and construct a transaction list.

[0098] For example, the transactions are selected according to the handling fees corresponding to the exchanges in the transaction list, and the selected transactions are packaged into blocks, including: traversing the transaction list; and selecting a preset number of transactions to form a block according to the handling fee information contained in the transaction. For example, an algorithm can be written to select targets according to the level of transaction fees to select the optimal transaction combination. Usually, transactions with higher handling fees are selected as priority packaging objects. The selected transactions can be packaged into new blocks and added to the blockchain.

[0099] S4. Generate a consensus node of the network node.

[0100] In an embodiment of the present invention, specific nodes are selected from network nodes as consensus nodes, which are responsible for verifying transactions, packaging blocks and maintaining the consistency of the entire blockchain network. The consensus nodes are configured to use a specific consensus algorithm to reach a consensus on the validity of new blocks.

[0101] In an embodiment of the present invention, the generation of the consensus node of the network node includes: determining which nodes will become consensus nodes in the network based on the trust, computing power, participation, etc. of the nodes; for the selected nodes, identity verification is performed to ensure that they have appropriate permissions and identities to participate in the consensus process, and the identity verification can be digital identity verification, access control list, etc.; selecting an appropriate consensus algorithm to ensure consistency between nodes, common consensus algorithms include Proof of Work (PoW), Proof of Stake (PoS), Delegated Proof of Stake (DPoS), etc.; configuring the software and hardware environment of the consensus nodes to ensure that they can correctly execute the selected consensus algorithm and communicate with other nodes; when the consensus nodes are ready, starting the consensus process so that the nodes can reach an agreement based on the selected consensus algorithm, verify and confirm new transactions, and add them to the blockchain.

[0102] Furthermore, consensus nodes can be monitored and managed to ensure their normal operation and perform troubleshooting and maintenance when necessary; appropriate reward mechanisms can be designed to incentivize consensus nodes to participate in the consensus process and ensure that they comply with protocol rules and maintain network security.

[0103] S5. Use the consensus node to process the block on the chain to obtain an updated blockchain network.

[0104] In the embodiment of the present invention, the process of using the consensus node to process the block on the chain to obtain an updated blockchain network includes:

[0105] Using the consensus node to broadcast the block to network nodes in the blockchain network;

[0106] Using the network node to verify the validity of the block;

[0107] When the total number of verification passes for the block validity verification is greater than a preset verification threshold, the network nodes reach a consensus and add the block to the blockchain network.

[0108] In detail, the consensus node is used to broadcast the block to the network nodes in the blockchain network, and the network nodes are also selected nodes with a consensus algorithm.

[0109] In detail, the consensus node broadcasts the generated new block to other nodes in the entire network. After receiving the new block, other nodes will verify its validity, including whether the transaction is legal, whether the block hash is correct, etc. Once most nodes have passed the verification, they reach a consensus to add the block to the blockchain and complete the update of the blockchain network.

[0110] In general, through the consensus mechanism, the blockchain network can achieve distributed authoritative authentication and data consistency in a decentralized environment, and the node competition process is the key to ensuring that the creation and addition of new blocks are fair and effective.

[0111] In detail, the using the network node to verify the validity of the block includes:

[0112] Using the network node to verify the legitimacy of transactions in the block;

[0113] Hash verification is performed on the blocks that have passed the transaction legitimacy verification.

[0114] In detail, the format of each transaction in the block is verified to ensure that it complies with the specifications and protocols of the blockchain network, and the signature of each transaction in the block is verified to ensure that the sender of the transaction has sufficient permissions and the transaction content has not been tampered with.

[0115] In detail, check whether each transaction has double-spending problems, that is, the same asset is used multiple times, to ensure the uniqueness and consistency of the transaction, and confirm whether the input and output of each transaction are legal, that is, whether the input of the transaction comes from a valid transaction output, and whether the output complies with the account balance and rules.

[0116] Furthermore, the same hash algorithm is used to calculate the data of the entire block to generate a hash value as the unique identifier of the block, and the calculated hash value is compared with the hash value recorded in the block header to ensure that the two are consistent.

[0117] Furthermore, if the Proof of Work consensus algorithm is used, it is also necessary to verify whether the proof of work of the block meets the difficulty requirements set by the network.

[0118] Through the above steps, network nodes can verify the legitimacy of transactions and hash verification on blocks to ensure that transactions in blocks are legal and the data integrity of the entire block is guaranteed. These verification processes are important links in ensuring security and consistency in blockchain networks.

[0119] The embodiment of the present invention performs asymmetric encryption on account information. After asymmetric encryption, even if it is intercepted during transmission, its content cannot be directly interpreted, thereby effectively protecting the confidentiality of account information. Secondly, transactions are broadcast and verified through the blockchain network. All participating network nodes need to sign and verify the transactions to ensure the legality and authenticity of the transactions. This distributed verification mechanism prevents single point failures and tampering risks, greatly improving the integrity and credibility of transaction data. Finally, the consensus algorithm of the blockchain ensures that transactions are confirmed and recorded in tamper-proof blocks, further enhancing the security and transparency of account management, and effectively preventing potential fraud and data tampering. That is, the method effectively solves the problem of low security in traditional corporate bank account management through the combination of encryption and distributed ledger technology. Therefore, the corporate bank account management method based on the supply chain platform proposed in the present invention can solve the problem of low security in bank account management.
