at present, each enterprise recruits a special accountant to take charge of a series of processes for account checking, and the responsibility of the accountant comprises the following steps:
1. accounting and supervision are carried out on accounts, so that the accounting processing is ensured to be timely, the application of accounting subjects is accurate, and the accounting information is real and complete;
2. verifying the legality, the accuracy of money amount, the completeness of procedures and the like of the original voucher, and verifying whether the signature, the date and the endorsement content of the service settlement bill are correct or not;
3. inputting (compiling) a bookkeeping voucher, taking charge of accounting voucher collection, book registration and printing and outputting the bookkeeping voucher and the book;
4. accurately and timely compiling accounting reports of units, and timely providing related accounting information according to enterprise needs;
5. the method comprises the following steps of binding accounting documents such as accounting documents, account books, reports, magnetic disks and related file systems by classification at regular intervals, keeping the accounting documents properly, and handing over a file room according to regulations;
all the above works need to be completed by accountants based on the seriously and the liability attitude, and all the related vouchers, bills, accounts and reports need to be accurate, and the accounts cannot be freely changed by other factors; furthermore, the upper-layer auditors of the accountants can check the accuracy of the accounts, and consider whether the accounts are reasonable from a higher category and whether the audited reports can be submitted upwards; the financial management personnel at a higher level need to undertake greater auditing responsibility, so that the absolute trueness and accuracy of the total account in the enterprise are ensured;
for the service contents and terms with various projects provided by the current telecommunication operators, the right obligation of the opposite party needs to be clarified when the customer signs a service agreement, and a large amount of details which need to be confirmed by both parties are included; especially, in the current practice of using electronic devices to perform service confirmation and service agreement signing, the confirmation certificates and payment certificates of a plurality of related services or the certificates of the operator's fulfillment agreement are stored in the electronic system, but due to the existence of various possibilities of influencing the security of stored data, for example, data damage occurs inside the electronic system, or the electronic certificate is intentionally tampered by people, the credibility of the electronic certificate is influenced; this is a big disadvantage of data centralization operation, so the technical scheme is proposed to solve the above mentioned disadvantages;
in this embodiment, the nodes of the basic link layer include a large number of user nodes of telecommunication services, nodes of a telecommunication operator and nodes of a relevant management department of the telecommunication industry; the electronic contract generated by the general ledger layer is supervised and verified through a large number of nodes, whether the user requirements collected by the service application program are correctly matched with the electronic contract or not can be verified, and the electronic contract is prevented from having terms with loss and fair openness;
further, as shown in fig. 3, the electronic contract is an intelligent contract applied to the block chain technology; the actual bottom layer of the intelligent contract is a section of automatically executable electronic contract program; the electronic contract program can automatically activate the execution content of the intelligent contract according to certain preset rules, preset time and preset conditions, thereby implementing the right obligation specified on the contract on the chain and realizing different response effects; after the electronic contract is generated, the electronic contract is finally written into a block of the general ledger main chain through the verification of the full-chain node; the block chain technology determines that the generation and the recording of the electronic contract have high consistency and non-falsification characteristics; furthermore, the electronic contract can obtain credit endorsements of all nodes on the general ledger main chain and the interaction chain through broadcasting on the blockchain;
the private key S issued by the basic chain layerkAnd said public key PkGenerated by using asymmetric encryption technology, through the private key SkThe encrypted information can be passed through the public key PkPerforms decryption and cannot perform a back-off operation to derive the private key Sk(ii) a Otherwise, the public key PkThe encrypted information may be provided by a private key SkCarrying out decryption; asymmetric encryption techniques are well known to those skilled in the relevant art and are not explained herein; after the basic chain layer issues a key with a client, an information file needs to be established for the client and relevant information of the client is collected; further, the basic chain layer adopts the public key P of the client for the information of the clientkIs encrypted and can be encrypted only by the private key SkThe client information is obtained through decryption, and the privacy of the client is effectively protected;
further, the client needs to use its own private key S when signing the electronic contractkDigitally signing and making electronic contracts possible on other nodes by verifying said public key P of the customerkConfirming the identity of the client; to this end, the basic chain layer completes basic verification of the electronic contract, individual verification of a client and validity verification of the behavior of 'the client signs the electronic contract';
further, the advanced chain layer is established in a form of a union chain; all nodes of the advanced link layer need to be selected from existing nodes of the basic link layer and the general ledger main chain in an election mode, and the purpose is to enable the advanced link layer to exclude partial nodes with low verification participation and low relevance to telecommunication value-adding service; the advanced chain layer carries out right obligation examination on the electronic contract signed by the user and confirms that the client is qualified to obtain the right contained in the electronic contract, such as the online time, the online annual capital, the total consumption amount and the like; and confirming that the client has the capability of fulfilling obligations required to be fulfilled by the electronic contract, such as whether the user is pre-paid or not and whether an automatic fee deduction function is opened or not; meanwhile, the advanced link layer verifies whether the telecommunication operator has the obligation capacity contained in the electronic contract, for example, the preset network speed of the signal at the position of the customer can meet the network speed listed by the electronic contract, or the number of people who access the network at the same time when the facility in the position can meet the requirement of the customer; through the work of the advanced chain layer, the right obligations of both parties contained in the electronic contract are refined and verified, and the signing of the contract is ensured to be in line with the capability and the benefit of both parties;
further, the general ledger main chain is responsible for carrying out final verification on the electronic contracts and the credible certificates verified by the advanced chain layer, and writing account items needing to be executed into a latest block of the general ledger main chain for further verification of the general ledger main chain;
through the writing mechanism, basic works such as generating certificates, collecting certificates, arranging accounts, verifying clients and the like are handed to the basic chain layer, and a large number of basic nodes complete bottom layer verification; the detail content of the electronic contract is verified relatively high-grade and perfect by the advanced chain layer and is used as a credit endorsement of the credible deposit certificate; the general ledger main chain is used for generating the electronic contract in a standard form, finally verifying the signed electronic contract and writing the electronic contract into the ledger, the whole writing mechanism completes closed-loop operation, and normalizes and standardizes the data format of the electronic contract from the source, so that nodes with different working capacities are verified and participate in verification work at different stages, and the calculation power of the nodes on the chain is optimized; the credit level and consistency level are also improved to a certain extent after the credit is verified.
Example two:
this embodiment should be understood to include at least all of the features of any of the foregoing embodiments and further modifications thereon; as mentioned previously, the nodes of the base chain layer include customers of the telecommunications operator, servers on the telecommunications network, and servers of the telecommunications regulatory body; because the basic link layer needs a large number of nodes represented by clients to perform on-link maintenance and participate in on-link verification, the present embodiment proposes a node maintenance scheme including an incentive mechanism to implement that the basic link layer maintains a sufficient number of client nodes;
in terms of hardware, because nodes participating in block chain verification need to have sufficient confidentiality, the existing access network equipment of a client can be improved by a telecommunication operator, so that the equipment has a safe software and hardware equipment environment; mature operating environment protection technical solutions, such as TEE trusted execution environment technology, are available at present; the technology can be applied to mobile terminal equipment such as mobile phones, tablet computers, portable computers and the like in a mature mode; the technology establishes a relatively isolated operation space in an operation system of the equipment and is provided with an independent kernel system, so that the related encryption operation is not interfered by the current operation system; further, when a client needs to enter the space of the trusted execution environment, it needs to log in by using various decryption operations, such as: fingerprint, iris, memory code or said private key SkThe verification means ensures that the client obtains safe software and hardware conditions;
furthermore, since the verification node needs to spend network traffic to transmit and receive data, and as time goes on, the block data on the chain becomes huge, and the network traffic to be consumed also gradually increases; therefore, for the client using the mobile device to make node bearing equipment, the operator identifies the directional communication of the part of the client connected to the basic chain layer, and the method avoids the worry that the client needs extra expense when participating in the node work in a free flow or additional flow giving way;
further, when the basic chain layer initiates verification of all chain nodes in the chain each time, the public key P of the node currently participating in verification is recordedkAnd performing integral addition on the nodes participating in verification; an operator regularly counts point records, rewards materials for customers with higher points and stimulates customer groups to participate in node work;
furthermore, for nodes with long online time, large workload and high verification accuracy, the nodes are recommended to be added into the alliance chain of the advanced chain layer and simultaneously take charge of the nodes of the advanced chain layer to work; and the node at the advanced link layer has richer reward than that of the basic link layer;
more active nodes can be obtained to participate in the interaction chain through an incentive system, a more decentralized accounting ecological environment is formed, and the writing mechanism obtains higher credit and working efficiency.
Example three:
this embodiment should be understood to include at least all of the features of any of the embodiments described above and further refinements thereto: because the technical scheme needs to perform a series of chain operations on the electronic contract from drafting, generating, verifying and signing, secondary verifying, bookkeeping and posting, and needs to be completed through an automatic program, the one-to-one correspondence between service items and accounting subjects can be greatly improved by matching with the current intelligent contract technology; thereby increasing the verification and calculation speed of the step chain when generating a trusted deposit certificate;
firstly, the financial department of the operator needs to uniformly establish an accounting subject rule aiming at the value-added service; the general rule comprises income items, income departments, income modes and the like corresponding to different value-added services, and profit and loss conditions, conversion cost, procedure calculation, commission and the like of different income items; according to the general rule, an automation program operated by the nodes on the general rule main chain definitely accepts and carries out the work flow and the execution rule of the general rule, and ensures that all the nodes carry out accounting subject processing and generate a uniform bookkeeping template according to the same standard and scale in the process of generating the credible deposit certificate according to the electronic contract processing;
for example: the value-added service items required by the customers comprise a voice mailbox item, the cost is 90 yuan per year, the value-added service items are signed and used for 3 years in a full prepayment mode, and the customers are promised to automatically give away the service life of 1 year after the value-added service items are used for 3 years; the description of the value added service can be made according to the accounting general rule as follows:
field 01-accounting: code 00002, voice mailbox;
field 02-income money: 270 yuan;
field 03-revenue department: A23G, a telecommunication business service hall in a certain city;
field 04-time: MM month DD day in YY year, NN score in HH year;
finally, standard fields { <00002>, <270>, < A23G >, < YYMMDD-HHNN > } based on communication on the chain are formed; the accounting account forms a standardized field, so that the higher operation efficiency and the uniform verification process are ensured when the accounting account information can be read by all verification programs on the chain;
