1. Zheshang Bank’s blockchain bill system is

a digital bill.
The bill is a valuable certificate, which always requires a hidden "third party" role in the transmission to ensure the safety and reliability of both parties to the transaction.
But with the help of the blockchain, there is no need for a third party to supervise and verify the information transmitted by the value of the transaction parties, nor does it require specific physical objects as proof of trust between the two parties, realizing the point-to-point transfer of value. Intangible" transmission.
Digital bills are not a new physical bill, nor a simple virtual information flow. It is a brand-new bill developed using blockchain technology and combined with existing bill attributes, regulations and markets. The form of bill presentation is completely different in technical architecture from existing electronic bills.
The advantages of the blockchain ticket platform are as follows: system construction and data storage do not require a central server, nor central-level applications; data integrity, transparency and verifiability through timestamps are critical to any value exchange All can be tracked and queried; the form of smart contracts makes the notes programmable and controllable throughout their life cycle.

5. Digital bills

Bills are an important financial product in the financial market. They have dual functions of payment and financing. They are of high value and bear bank credit or commercial credit. Once a bill is issued, its face amount, date and other important information cannot be changed. Bills also have circulation attributes and can be accepted, endorsed, discounted, rediscounted, collected and other transactions within a specific life cycle. Once the transaction is completed, the transaction cannot be revoked. There are two characteristics in the circulation of bills: First, the circulation of bills mainly occurs through bank acceptance bills, and the number and circulation of commercial acceptance bills are small; second, each bank independently conducts credit granting and risk control on the bill business, and a single bank's Risk control results may affect other participants in the bill market transaction chain.

The experimental production system of the digital bill trading platform uses SDC (Smart Draft Chain) blockchain technology, using cryptographic algorithms such as homomorphic encryption and zero-knowledge proof for privacy protection, and through the practical Byzantine fault-tolerant protocol ( PBFT) conducts consensus and uses a see-through mechanism to provide data monitoring.

The experimental production system includes four subsystems: stock exchange, bank, enterprise and monitoring: the stock exchange subsystem is responsible for managing the blockchain and monitoring the digital bill business; the bank subsystem has Digital bills have business functions such as acceptance and receipt, discount signing, rediscounting, and collection and repayment; the enterprise subsystem has business functions such as issuance, acceptance, endorsement, discounting, and prompt payment of digital bills; the monitoring subsystem monitors the status of the blockchain in real time and business occurrences

3. What are the blockchain bill platform development plans

The combination of blockchain and bills can be developed into digital Bills, so-called digital bills, are not a newly created physical bill, nor a simple virtual information flow. It is a brand-new bill developed using blockchain technology and combined with existing bill attributes, regulations and markets. The form of bill presentation is completely different in technical architecture from existing electronic bills. For the specific content of the plan, I think you can take a look at Yingtang Zhongchuang, which is relatively good at blockchain application development.

4. What is the current status of blockchain on bills across the country

Blockchain has developed rapidly in 2020, and many applications have been implemented. Only Ant Financial has implemented blockchain technology. There are already more than 40 application scenarios, covering scenarios such as commodity traceability, public welfare traceability, cross-border remittance, supply chain finance, and electronic bills. With the continuous breakthroughs in blockchain application scenarios, bills in supply chain finance, cross-city travel, charity fundraising and other fields have also ushered in the era of comprehensive blockchainization. Blockchain technology can solve the trust problem. Blockchain electronic bills are replacing paper invoices, and blockchain electronic bills are being rolled out across the country. Crypto Finance mimacaijing, focusing on blockchain information.

5. What are the nodes on the blockchain jointly maintaining?

Each node on the alliance chain. Blockchain tickets are jointly maintained by all nodes on the Xingxiaohe Alliance chain. The on-chain data is recognized by all nodes and is completely recorded, cannot be tampered with, and can be traced back. "Blockchain + Bill" is a new type of bill based on blockchain technology and based on the attributes of current bank bills and merchant bills, laws and regulations, bill supervision regulations and market demand.

6. Breaking 100 million in 6 months! Zhejiang Provincial Department of Finance and Ant Blockchain bid farewell to paper tickets

Zhejiang Online, January 15 (Zhejiang Online Correspondent Chen Jieqiong) In order to better solve the "run once problem", local governments are increasingly applying new technologies. Coming faster and faster.Recently, Ye Shibao, director of the Electronic Invoice Center of the Zhejiang Provincial Department of Finance, said in an interview that since the establishment of the provincial blockchain electronic invoice platform in June last year with Ant Blockchain, as of the end of 2019, 507 medical institutions in Zhejiang Province have been on the blockchain. , 74 public hospitals realized electronic bill reimbursement in other places within the province, 100 million fewer bills were issued, and more than 30 million bill printing costs were saved, once again at the forefront of innovation.

Interestingly, electronic bills have been promoted for many years but there are still many links that cannot be solved. Blockchain has become a key. It is understood that Ant Financial is the first company to explore the application of blockchain technology in digital government industries such as finance and taxation. Through Ant blockchain technology, electronic bills can be "stamped" throughout the entire process from generation, transmission, storage to use. The entire process is traceable and cannot be tampered with, ensuring that the authenticity of the bill can be quickly confirmed in every circulation link, thus Achieve cross-regional and cross-department settlement and reimbursement.

Ye Shibao said that according to previous statistics, the entire process used to take about 12 working days to go to the medical insurance department for reimbursement, while commercial insurance reimbursement took longer, taking 7-60 working days. Now you no longer need to hold the ticket and stamp it in several places, you can quickly receive it with just a few clicks on your mobile phone.

Zhejiang University Shaw Hospital is one of the first hospitals in the province to go online. For Zhao Yue, a bill administrator who has worked in the finance department for 30 years, this is also a good thing.

In the past, he manually reviewed half-meter-high stacks of receipt stubs every day, and packed a large box every eight days on average. The pile could not fit in the office, and he would ask his colleagues to move it to the warehouse for storage. After receiving it and then doing the write-off, "it will take several months to complete the entire process." Nowadays, fewer and fewer bill stubs are collected every day, from the original half meter high to ten or twenty. "The warehouse is no longer needed, and several vehicles that transport the bills for destruction have also been returned."

The full link between hospital electronic bills and reimbursement and claims has been opened up, ultimately improving the patient experience in the "last mile" of medical treatment. Taizhou Hospital dared to be the first to allow Mr. Pang, a local resident, to receive reimbursement without traveling for 7 hours at a time when he was on a business trip to Hangzhou for medical treatment. He became the first person in the country to realize the reimbursement of medical insurance in other places through blockchain electronic bills.

The changes in each hospital are just the tip of the iceberg. Subway ticket settlement on the chain allows users to pass with one code, Hangzhou Internet Court introduced the Ant blockchain, provident fund withdrawal, etc. Zhejiang Province has completed implementation in more than 26 fields. From mobile payment to digital economy, Zhejiang has always been ahead of the curve in the application of innovative technologies.

At the 2020 Zhejiang Two Sessions held recently, Jing Xiandong, a member of the Zhejiang Provincial Committee of the Chinese People’s Political Consultative Conference and chairman of Ant Financial, said that he will continue to use AI and blockchain to promote the upgrading of Zhejiang’s digital government affairs and promote Zhejiang to become a national Digital government model province. In the future, only applications that benefit the real economy and the public will be truly valuable applications, and blockchain must fundamentally move away from virtuality and into reality.

7. What changes will blockchain bring to electronic bills?

First, it can identifyThe electronic voucher is authentic and there is no need to worry about being maliciously tampered with or forged.
Second, the third-party hosting model can effectively reduce the cost of enterprise system construction and operation and maintenance, and the method of querying and obtaining electronic vouchers from a credible third party provides a safe and reliable acquisition channel for enterprise users.
Third, solving the trust bottleneck faced by the data storage industry will help business development.
Fourth, electronic vouchers can be traced by recording electronic voucher summaries and circulation records to meet the needs of business supervision and review.
Deepin Bill Network and Xingye Digital Finance launched the bill witness system, which provides solutions to possible risks in electronic bill transaction scenarios. The ticket payment witness is the DVP of the ticket transaction between enterprises, which adopts the transaction model of "pay first and then endorse", that is, the buyer first transfers the money to the Industrial Bank's special fund custody account, the seller confirms that the funds have been received, and then endorses, and the Industrial Bank system verifies the electricity. Funds will be released after the ticket is successfully signed. During the entire transaction process, Deepin Bill Network only provides safe, efficient and convenient services and does not touch funds and electronic tickets to ensure the safety of funds and electronic tickets.
