When Bitcoin is ups and downs, altcoins never return, and the reputation of "blockchain" is hard to guarantee. Actually not necessarily!
In early August, restaurants in Shenzhen and hospitals in Zhejiang issued blockchain invoices for the first time. It is open and transparent and prevents violations. Your life may be "chained" very quickly.
Blockchain invoice has been appliedBlockchain, an open and transparent account, is also an iron account. Once it is recorded, it cannot be reversed.
The blockchain has no central node. It's as if there is no village accountant in a village, everyone keeps accounts, and everyone stores everyone's accounts. Therefore, there is no danger of the village accountant tampering with the accounts. Therefore, the blockchain can solve the credit problems of all walks of life.
According to media reports, on August 10, Shenzhen International Trade Revolving Restaurant issued the country's first blockchain electronic invoice. The issuer, the receiver, and the tax bureau are all on the blockchain, so everyone can be sure that the bill is true. Once this kind of invoice is promoted, the reimbursement will not have to post the invoice and fill in the bill; the reviewing financial staff will also save the worry.
Coincidentally, the three hospitals in Hangzhou, Taizhou, and Jinhua will issue blockchain bills from August 2; reimbursement and leave certificates can be issued with electronic tickets, and there is no need to queue at the window.
Ant Financial's blockchain business expert Yang Xueqing told the media: Blockchain bills "generate-transmit-use" and "stamp" throughout the entire process to prevent repeated reimbursement; because the "stamp" of "reimbursed" cannot be tampered with. This was impossible in the past.
"Compared with traditional technology, blockchain means shorter time, less manpower and maintenance costs," said Zewu Changjiang, a research institute of Hash World Research Institute. "Blockchain will facilitate safe and reliable audit management and Accounts are cleared to reduce the possibility of crime and various security risks."
Both hairy crabs and video games may be on the "chain"Shen Jie, the overall group leader of the National Internet of Things Basic Standards Working Group, gave an example: There are too many hairy crabs on the market labeled "Yangcheng Lake Production". Although they all have "certificates" or "data records," they cannot be true. If consumers want to restore trust, blockchain can help.
Shen Jie introduced a case in the Yangtze River Delta to a reporter from Science and Technology Daily. Blockchain is used in fisheries: IoT sensors monitor the water quality of fish ponds, and the data is uploaded to the blockchain; financial institutions provide loans to farmers based on the data; farmers make consumers Traceable products, get more profits.
According to reports, a large e-commerce company has also introduced blockchain in agriculture, allowing a cow to be put on the shelves from birth to shopping malls. Every step of the data is on the blockchain. There is no doubt.
Shen Jie believes that in the digitalized field, blockchain is easier to land. "One is digital copyright, such as the intellectual property rights of Internet music; the other is the gaming industry. Internet gaming is difficult to avoid fraud. With blockchain, credit can be established."
Shen Jie said: "Another possibility is the virtual revenue of games, such as points. In the past, these points are useless if you leave the game. Blockchain may promote the interoperability of various games."
The bank may be the backing funder"Now many banking businesses have been prepared, or the block chaining of transaction data has been implemented, which has greatly improved the efficiency of cross-border and cross-bank remittances." Jiang Zewu said, "blockchained public ledgers can enable various countries and banks The data of the system is interconnected and updated in real time."
Jiang Zewu said that in the fields of payment, real estate finance, asset securitization, asset management, bill finance and other fields, blockchain can better control risks and reduce transaction costs.
"Real estate agencies and banks will definitely like the second-level services brought by blockchain technology." Kong Lingxin, CEO of Shell Financial Holdings Group, told the reporter of Science and Technology Daily that the blockchain can make a progress in a few seconds and it takes many days. Completed real estate transaction.
Kong Lingxin said that the bank’s pain point is that it is difficult to verify a lot of information for risk control: the actual salary of the buyer, the actual social security and provident fund, etc., and the blockchain can prevent data falsification.
"It is precisely because banks have far higher requirements for real data than other industries. Now many banks are actively embracing blockchain technology, including investment in blockchain projects, behind which are banks and other large financial institutions." Kong Lingxin said .
Although the transaction volume of the blockchain system is still a fraction of the mainstream world financial transaction system, the financial sector is very active. In the past five years, the most active patent applicant in the blockchain field has been the US-based payment giant MasterCard, followed by Liechtenstein-based n-chain Holdings. Famous companies applying for blockchain patents also include giants such as Bank of America and British Telecom.
