Blockchain, as the underlying system of the new generation of Internet, can integrate other new generation of information technology, improve the growth rate of digital economy, ensure the rapid economic growth and high-quality development, and accelerate the transformation and upgrading of economic development. At present, what are the technological innovations of blockchain based on industry application? What applications have been made in the areas of people's livelihood? What will the new generation of technological revolution triggered by blockchain bring to the high-quality economic development? On December 28, 2019, at the symposium themed "application and development of blockchain technology", members, experts and scholars gathered together to discuss how to promote the realization of greater value of blockchain technology.

Blockchain creates a whole new way of trust

In 2019, great changes have taken place in the Internet industry, which is shifting from the consumption Internet to the industrial Internet, and data is increasingly turning into assets from information flow. It can be said that data has become the most important factor of production in the era of digital economy. Wei kai, deputy director of the institute of cloud computing and big data at the China academy of information and communications technology, said blockchain is an opportunity to solve "inherent problems" such as untrustworthiness and difficulty in determining power in the digital economy.

From the social perspective, different from traditional society, blockchain technology has created a new way of trust. Zhang yunyong, a member of the national committee of the Chinese people's political consultative conference (CPPCC), secretary of the party committee and President of China unicom research institute, believes that there are four main reasons for the popularity of blockchain: first, strategic orientation; second, science and technology orientation; third, people's livelihood orientation; and fourth, industry orientation. The more attention paid to blockchain, the more questions were raised. Zhang yunyong said that block chain is equal to block plus chain, but now this chain is not the traditional chain, has developed into a very complex multi-structure. In addition, it is not accurate to say that blockchain is decentralized. In fact, the real meaning of blockchain is that there is no center, not absolute decentralization. "At the same time, we need to make it clear that blockchain does not equal bitcoin." Zhang yunyong said.

From the perspective of the current application scenario of block chain, there are four main features. First, the scope is wide. Widely used in the financial and real economy fields, mainly through mathematical principles rather than third-party intermediaries to create trust and reduce system performance costs. The second is to improve efficiency. In cross-border payment, global trade, logistics, supply chain, finance, credit investigation and other fields, block chain can quickly integrate physical flow, data flow, information flow, capital flow, simplify the verification, reconciliation, approval, clearing and other transaction processes. The third is cross-subject. To solve the value chain is particularly long, the communication links are complex and there are game behavior between each other. Fourth, reduce costs. It is beneficial to confirm the right of data, promote information sharing and circulation, thus reducing the cost.

"Block chain ﹢ carrier" achieve more value

The application of block chain technology in taxation is mainly reflected in electronic invoices. In March 2018, shenzhen city, guangdong province tax bureau developing "block chain ﹢ electronic invoice", on August 10, the first to open the first block chain electronic invoice. Zhang zhiyong, a member of the national committee of the Chinese people's political consultative conference (CPPCC) and former deputy director of the state administration of taxation, said blockchain technology provides a solution to the problems of false invoices, tax evasion and using invoices to defraud tax refunds. Block chain invoice has four characteristics: transaction is invoicing, invoicing is reimbursement, invoice is data, realizing the integration of "capital flow, invoice flow and data flow"; Full information chain, real-time monitoring of the whole process; The data is safe and reliable, tamper-proof and traceable; The whole process gets through to form a complete closed loop on the business line. By December 24, 2019, shenzhen's tax authorities had issued more than 14.2 million block chain invoices, worth 9 billion yuan, to more than 12,000 enterprises.

Technology has the carrier, has the life. Block chain technology can only be more valuable if it can be applied to the people's livelihood. "It is imperative to integrate advanced technology into the judicial field." Gao zicheng, a deputy to the National People's Congress and President of the Beijing lawyers association, said that with the continuous penetration of the Internet into people's lives, electronic evidence is playing an increasingly prominent role in judicial activities around the world, and electronic evidence composed of electronic data has gradually become the most mainstream type of evidence. However, in the traditional judicial practice, due to the high cost, low efficiency and difficulty in obtaining the authenticity of the above evidence, electronic evidence directly affects the proportion of obtaining the evidence in litigation. Compared with the traditional certificates with high cost, low efficiency and difficulty in guaranteeing authenticity, electronic data certificates with block chain technology can prevent human tampering, effectively secure certificates, and can be traced back to the source, and can be verified at any time due to its features of distributed accounting and consensus mechanism. Through the consensus mechanism, various public trust institutions on the block chain reach multi-party consensus and mutual trust, and electronic evidence goes straight to the court, greatly saving the time wasted in verifying whether the evidence has been tampered with, and improving the legal effectiveness of data and judicial efficiency. "In the future, blockchain certificates with the core advantages of high efficiency, low cost and trustworthiness will have considerable value in the judicial field." "Gao zicheng said.

The first year opened, innovative applications have also begun to bloom. When it comes to the application and development of blockchain in the future, tan jianfeng, a member of the national committee of the Chinese people's political consultative conference (CPPCC) and chairman of Shanghai zhuge network security technology co., ltd. believes that blockchain will gradually become an important part of the future Internet development, and with the increasingly rich application scenarios, the combination of blockchain and cloud will be closer. However, it should be noted that although block chain is mathematically complete, it also has security problems. In the future, it needs to strengthen security from the aspects of application, engineering and management, and enhance the credibility of standard processes. More importantly, blockchain technology needs to gradually adapt to regulatory policy requirements in order to develop applications more effectively.
