Detailed Description
The invention is further described in detail below in connection with the detailed description.
The embodiment provides a bill binding system, which comprises a processor and a computer readable storage medium. The computer readable storage medium stores an executable bill binding program (i.e., a computer program), and a processor of the electronic terminal runs the bill binding program to implement the blockchain-based bill binding method as shown in fig. 1.
The following details the execution of the blockchain-based ticket binding method.
And a project node generating step, wherein if any node on the bill alliance chain uploads project information carrying the bill on the blockchain, the project node is newly generated, and the newly generated project node verifies the authenticity and the validity of the electronic bill through the intelligent contract.
A sub-chain constructing step, namely constructing a sub-chain between the invoicing node and the invoicing associated person through the project node, specifically, reading the invoicing associated person in the project information, identifying the invoicing node bound by the invoicing associated person, establishing a unidirectional sub-chain pointed by the invoicing node to the project node and pointed by the project node to the invoicing associated person, so that the invoicing associated person is synchronously given by the sub-chain after the invoicing associated person issues the bill associated with the project information.
The data/information uplink process for a blockchain is described in detail below.
In creating a transaction, in a blockchain transaction, a transaction first needs to be created. The transaction includes information such as sender, receiver, and transaction content. The sender needs to sign the transaction by using the private key of the sender, so as to ensure the authenticity of the transaction.
Broadcasting the transaction, after creating the transaction, the transaction needs to be broadcast to other nodes in the network. Each node adds the transaction to its own transaction pool to wait for processing.
The transaction is validated, and the node verifies the transaction, including verifying the sender's signature, etc. If the transaction verifies, the node packages the transaction into a chunk and adds the chunk to the blockchain.
Each node has the right to participate in the generation and verification of the block, and each node adds the block into the block chain after reaching the consensus.
The item information carrying the bill also comprises bill information, wherein the bill information comprises a bill number, a bill type, a bill surface amount, a bill date and an expiration date.
The new project node is a virtual node constructed on the billing node, and the project node acquires the intelligent contract from the billing node. If a new intelligent contract is negotiated between the newly generated project node and the billing node within a preset time period after the project information carrying the bill is uploaded to the blockchain, the intelligent contract is used as a contract template to be bound to the newly generated project node. The generated contract template is stored as a template library, and the contract template is matched with the newly generated project node at present according to the associated billing node and project information carrying the bill through a template referencing step.
Wherein at the item node of the blockchain, a unique identifier of the current transaction is generated from the order of the bound ticket and subchain, the unique identifier being stored in a database of the blockchain.
According to the bill binding method based on the blockchain, after project information is linked, project nodes are newly generated, communication channels among the project nodes, the billing nodes and billing associated persons are respectively opened, the project nodes are further used as transit to construct sub-links between the billing nodes and the billing associated persons, the billing associated persons in the project information are firstly read when the sub-links are constructed, the billing nodes bound by the billing associated persons are identified, the billing nodes pointed to the project nodes by the billing nodes are sequentially established, and then the project nodes pointed to the billing associated persons are unidirectional sub-links, so that the billing associated persons are synchronously given by the sub-links after the bills associated with the project information are linked by the billing nodes, and as the sub-links only record the bill linking information of one project, only the billing associated persons can read the bill information from the sub-links, and other persons cannot read the bill information bound on the sub-links from the public links, so that the possibility of bill information leakage is greatly reduced.
