The main contradiction of the block chain industry at this stage is that the contrast between the ideal of plumpness and the reality of bone sense is still in the stage of social experiment in technology, with a "hammer" in the scene looking for "nails" everywhere.
It is understood that in the first pilot application, Shenzhen Tax Bureau, Tencent, Jindi software tripartite cooperation, to create a "Wechat payment - invoice issuance - reimbursement" application scenario of the whole process of invoice management.
Tencent block chain landing again
According to the on-site demonstration, a consumer in Shenzhen International Trade Rotary Restaurant completed the payment of 198 yuan with Wechat, clicked "invoice", an electronic invoice with face value of 198 yuan was issued, the password area of the invoice was displayed by hash value, and then entered the "Golden Butterfly Invoice Cloud" system through two-dimensional code, the electronic invoice was imported. The "Golden Butterfly Invoice Cloud" will synchronize the reimbursement information through the block chain to the block chain cloud computing node of Shenzhen Tax Bureau in real time, thus completing a closed loop.
Previous invoice circulation scenarios are characterized by many participants, long circulation cycle, information between the participants is not interoperable, there are tampering and other pain points. Block chain is a kind of stepwise bookkeeping technology which can not be tampered with to prevent non-repudiation and deletion. Now as the core technology of block chain electronic invoice, it can play two core roles:
1. Ensure that the invoice is unique and that the status of invoice receipt, invoice invoice invoice invoice invoice invoice invoice invoice invoice, circulation, entry, reimbursement, and all links of circulation can be traceable.
2. Invoice data can not be tampered with. The tax bureau, the invoicing party, the circulation party and the reimbursement party participate in the joint accounting.
It is understood that this is not the first example of "block chain electronic invoice," the beach exploration has been surging, the market block chain electronic invoice related products emerge in endlessly, some technology companies have also carried on the first exploration.
In March 2017, Baiwang Shares and Wanda Network Technology jointly released Wanda E-account non-paper tax ticket block platform based on Baiwang stock invoice service. In January this year, Ruihong Network and Jingtong Network Technology Co., Ltd. of Donggang Stock Company reached a strategic cooperation to jointly construct an Ecosphere of electronic invoices, electronic bills, archives digitization, RFID and data application based on block chain technology.
In June this year, Fang Xin Technology R & D electronic invoice block chain platform "tax chain" in Guangzhou online. Guangzhou Gas Group Co., Ltd. is authorized by the tax authorities to join the block chain network and issue "upper chain" invoices to realize block chain storage, exchange and sharing on electronic invoices.
However, Cai said that unlike previous explorations of simply "overlapping" block chains on e-tickets, this is a proto-electronic invoice based on block chains. All links of block-chain e-invoices from the beginning of payment can be completed on the chain. It is an integrated tax management and control system, which supports a lot of hindsight. Renew ability, such as big data analysis and early warning. In contrast, the electronic invoice of block chain circulated in the market before is only a part of the transaction link to try on the chain, just based on the VAT invoice management system of new technological innovation, using the block chain to increase the role of storage, only played the value of the block chain can not be tampered with.
Regulators, businesses and consumers need what they need.
It is understood that at present, Shenzhen International Trade Rotary Restaurant, Baoan District Sports Center Parking lot, Kaixin Automobile Trading Co., Ltd. (Pingshan Automobile Workshop) and other merchants have been as the first batch of users, access to the block chain electronic invoice system. On the spot, tax supervision, merchants and consumers share the experience of block chain electronic invoice.
In the aspect of tax supervision, electronic invoices were saved in the form of electronic data, which were easy to be repeatedly downloaded and printed, and easily tampered with information through PS technology. It is easy to cause the potential risks of repeated reimbursement, double entry, false reimbursement and false entry of electronic invoices. Last year alone, Shenzhen State Tax Bureau and other four departments smashed 11 gangs and arrested 68 suspects. Tax authorities all over the country devote a great deal of manpower and material resources every year to rectify the market for false invoices, but like "cutting leeks", wave after wave of investigation has never been able to cure the problem.
In this regard, Li Ronghui, director of the Shenzhen Tax Bureau Information Center, said that the block chain electronic invoice can connect each invoice stakeholder, can trace the origin of the invoice, authenticity and reimbursement information, so that the whole scene of the circulation of invoice information into reality. In addition, the block chain electronic invoice combines payment with invoicing, realizes "transaction data is invoice", effectively solves the problems of inaccurate invoice filling, not open, less invoice, and ensures timely and full tax storage.
In terms of access to merchants, it is understood that the issuance of electronic invoices requires enterprises to purchase VAT invoice system upgrade royalty control equipment, self-built or entrusted to a third party to build an electronic invoice service platform needs to consume manpower, material and financial resources, especially for small enterprises, is a large expenditure. International Trade Restaurant Operations Manager Dai Jianghua said, "Now with the block chain electronic invoice, consumers can check out their own on the Wechat invoice, do not need our manual invoice input information, nor do we need additional hardware support. Consumers can click on the WeChat mobile phone to pick up the tickets, and the tax authorities will be able to issue invoices after examination. Thus improving the efficiency of storefront operation and saving the management cost.
The trial consumer feedback, before eating a working meal, reimbursement needs to print the invoice, back to the company to stick the invoice, after the leadership approval to the financial reimbursement, received reimbursement needs to wait for several days. Now just import the invoice on Wechat, click "reimbursement", you can connect the reimbursement software, fill in information, a few minutes to complete.
Cai Yige said that the current block chain electronic invoice system has been connected to the tax bureau, Weixin payment, Weixin card packages, financial software vendors, businesses, consumers, as an open platform, the future will also access more third-party payment institutions and other different service providers.
In addition, it is understood that the current block chain electronic invoice will pay the data into the invoice issued to achieve the invoice flow and capital flow "second-class integration", or the future will be introduced into the cargo block chain, to achieve the invoice flow, capital flow, cargo flow "third-class integration".
How to ensure data security on up chain
In fact, the public is generally concerned about whether the chain of invoice data is safe and controllable.
In this regard, Li Ronghui said that the block chain electronic invoice deployment in the time to face three major challenges: first, the deployment of nodes, second, data security issues, third, system performance issues. Among them, data security is the primary goal of system design.
According to its introduction, after studying the application cases of block chain at home and abroad, the project team put forward the deployment scheme of "consensus node transaction node query node" on the basis of many argumentation, and adopted the mixed cloud structure of public cloud and private cloud. The consensus node chooses to deploy in some controllable sites, the total amount of data only falls on the tax intranet, and the other participants only have their own data and authorized query data, thus ensuring the credibility, traceability, controllability and traceability of invoice data.
In addition, relying on the block chain technology, the tax-related behavior of the invoice is linked with the operation behavior of the enterprise and the personal behavior of the core personnel of the enterprise. The former separate transactions and invoicing links are merged together to form a more perfect tax credit system.
Furthermore, Zhang Liangjie, Chief Technical Officer and Senior Vice President of Jindi Group, added that the block chain electronic invoice realized the transaction namely credit. All the transaction records are displayed on the block chain, which can not be tampered with. The transaction records form the credit chain of the enterprise. This credit chain will produce great value, including the loan quota of the enterprise, supply chain finance and so on. Therefore, in the future, "Block Chain Electronic Invoice" itself is value, is a gold mine, is an asset.
