Description
Technical Field
The invention relates to the technical field of electronic creditors, in particular to a block chain electronic creditor certificate implementation method and system.
Background
The block chain is a technical scheme for maintaining a reliable database in a centralized and distrusted mode. Any number of nodes participating in the system compute and record all information, data, over a period of time in the system to a block of data (block) by a cryptographic algorithm and generate a fingerprint of the block for linking the next block and checking.
The blockchain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism and an encryption algorithm. The consensus mechanism is a mathematical algorithm for establishing trust and obtaining rights and interests among different nodes in the blockchain system.
In a narrow sense, the blockchain is a distributed account book which is a chain data structure formed by combining data blocks in a sequential connection mode according to a time sequence and is guaranteed in a cryptographic mode and cannot be tampered and forged. Broadly speaking, the blockchain technique is a completely new distributed infrastructure and computing paradigm that utilizes blockchain data structures to verify and store data, utilizes distributed node consensus algorithms to generate and update data, cryptographically secure data transmission and access, and utilizes intelligent contracts composed of automated script code to program and manipulate data.
If the block chain is applied to the electronic creditor transaction, the data on the block chain cannot be tampered, so that the authenticity and the resistance of transaction information can be ensured.

the electronic credit right transaction member identity management module is used for managing the identity of the electronic credit right transaction member in the network;
and the electronic creditor certificate generation and storage module is used for packaging and uploading the related electronic creditor transaction data and storing the electronic creditor transaction data on the block chain as the electronic creditor certificate.
Further, the electronic creditor transaction member identity management module specifically adopts a digital certificate mechanism to realize PKI service.
Further, the electronic creditor transaction membership management module comprises,
the CA module is responsible for issuing and invalidating certificates and receiving requests from the RA;
the RA module verifies the user identity, verifies the data validity, is responsible for registration and verification, and sends the user identity to the CA module after the verification is passed;
the certificate database is used for storing certificates.
According to the technical scheme, the block chain electronic creditor certificate realization method and system form an electronic creditor, namely a creditor, on the block chain while signing in the trade credit contract through the two parties of the trade, and generate the electronic creditor on the block chain while trading. Meanwhile, the creditor and the debt outsider can check the current electronic credit balance through the credit wallet function provided by the system, and the creditor can transfer the credit to a third party through the transfer function of the electronic credit wallet; after the debt is due, the debt can be cashed to the debt holder through the debt wallet; after the credit of the creditor is cashed, the balance of the credit is correspondingly reduced; the entire life cycle of the claim may be viewed on the chain. Due to the fact that data on the block chain cannot be tampered, authenticity and resistance to repudiation of transaction information are guaranteed.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention.
As shown in fig. 1, the method for implementing a block chain electronic creditor certificate in this embodiment includes the following steps:
s100, setting a Peer node to be responsible for receiving a transaction request;
the Peer node is a service or software with a certain function in the network; maintaining an account book in each Peer node, wherein the data of the account book is a file system;
s200, an Order node is set to be responsible for carrying out global sequencing on the received transactions in the network;
specifically, a transaction is received, and a block is generated. And is responsible for policy management of the consensus mechanism;
s300, setting a CA node to be responsible for member identity management in the network;
at present, a digital certificate mechanism is adopted to realize PKI service. The device comprises the following three components:
1. CA: responsible for issuing and revoking certificates, receives requests from the RA. Is the most core component in the PKI service and mainly completes the management of the public key.
2. RA: the user identity is verified, the data validity is verified, the user identity is responsible for registration and verification, and the user identity is sent to a CA after the verification is passed;
3. a certificate database: and storing the certificate.
On the other hand, the embodiment of the invention also discloses a block chain electronic creditor certificate realization system, which comprises,
the electronic credit transaction receiving module is used for receiving an electronic credit transaction request;
the electronic credit transaction sequencing module is used for globally sequencing the received electronic credit transactions in the network;
the electronic credit right transaction member identity management module is used for managing the identity of the electronic credit right transaction member in the network;
and the electronic creditor certificate generation and storage module is used for packaging and uploading the related electronic creditor transaction data and storing the electronic creditor transaction data on the block chain as the electronic creditor certificate.
The electronic creditor transaction member identity management module specifically adopts a digital certificate mechanism to realize PKI service.
The electronic creditor transaction membership management module comprises,
