According to the report, the Chinese capital Beijing, the mega city Shanghai and Guangzhou in the South have all participated in the pilot project. 164 entities including local government departments, universities, banks, hospitals, automobile companies and power companies have become national blockchain innovation and application pilots.

The report points out that blockchain initially refers to the technology supporting cryptocurrency bitcoin. It is an open, vandal proof and unalterable activity account book. It is also "decentralized", which means that it is not operated by or owned by a single entity.

The report also said that the definition of blockchain has been expanded because many different industries want to use this technology for various purposes. Other names, such as "distributed ledger technology", are also commonly used now, which is different from the original bitcoin blockchain. However, the idea of a single, authentic record of activity is attractive.

It is reported that China's cyberspace regulators and other regulatory authorities jointly issued a notice on January 30, requiring "give full play to the role of blockchain in promoting data sharing, optimizing business processes, reducing operating costs, improving synergy efficiency and building a trusted system".

The notice said that all pilot units (regions) should give priority to the adoption of blockchain software and hardware technologies and products with interoperability and sustainable development ability.

Industrial blockchain is an important breakthrough in the implementation and application of the current blockchain technology development scenario. At present, the development of industrial blockchain is still in the primary stage. However, the industry generally believes that the theory and practice proposed in the era of industrial blockchain 1.0 have laid a foundation for the development of 2.0. Yu Jianing, chairman in office of blockchain special committee of China Communications Industry Association and President of Huo coin University, said that the era of industrial blockchain 2.0 is likely to come in 2021. The five most noteworthy areas in 2021 are industrial chain + asset chain + data chain + technology integration and the application of central bank digital currency.

Deng Weiping, head of strategic cooperation of small public bank block chain, shared the Guangdong Guangdong health code cross border mutual recognition system. He introduced that under the background of global COVID-19, Guangdong and Macao used the open source technology of micro public bank block chain to realize the cross recognition of "Guangdong Kang code" and "Macao Health Code". The mutual recognition system was opened in May this year, and as of November 20th, More than 28 million people have been served for customs clearance.

Hou Junhui, vice president of Jingtong technology, said that many applications may come out in 2021, and many killer applications with good operation, good potential or subversive value may emerge in 2022.

Liu Han, CEO of tea chain technology, said that tea chain technology combines blockchain technology + Internet of things technology + chip technology to truly empower the physical industry of tea. The direct value to tea enterprises is to promote the sales of tea, and the value to consumers is to trace the anti-counterfeiting of tea leaves bought by consumers on the platform to ensure the quality of tea.

Sun Xi, director of government enterprise relations of slow fog technology, said that slow fog technology hopes to use its own alliance chain full cycle security construction scheme to help improve the security controllability of enterprises for the current immature blockchain technology system, multilevel and standardize the blockchain security system, and protect the rapid and safe landing of blockchain applications in the future.

Chen Shijia, CEO of Wangxin Tiancheng Technology, believes that whether the blockchain can get a higher development depends on three elements: cognition, technology and policy. With the passage of time, more and more people know about blockchain, and their understanding of blockchain will become more and more. Now the technology of necking will be better next year. In terms of policy, there are many positive signals overseas and they are optimistic about the future.

The typical way of passive income is through the purchase and holding of cryptocurrency - also known as "hodling" in the industry. This means that investors are ready to buy a digital asset, and their mentality is to hope that its price will rise sharply at some time in the future. Such investors are ready to go a long way because this long-term strategy may require them to hold positions at any time within six months to five years. During this investment period, investors do not have to take the initiative in the cryptocurrency market. They just need to buy digital assets and store them in a Secure Wallet - preferably an unmanaged wallet.

A wallet is a device or application in which you can store a special key (private key) to access your cryptocurrency. Unmanaged wallet allows you to store private keys in personal devices, including computers, mobile phones or special wallet devices. With this, you can fully control your private key and ultimately control your digital assets. In contrast, using a managed wallet allows a third party to control your private key.

However, just the length of time you buy and hold cryptocurrency assets does not guarantee that you will make a profit. In fact, you are likely to lose money. Therefore, pure hodling cryptocurrency cannot be regarded as a real passive source of income.

Blockchain competition is becoming increasingly fierce

Patent competition has become an important field. With the increase of participants, the competition of blockchain will become more and more intense. In the future, enterprises will strengthen the layout of blockchain patents, which are mainly distributed in the United States and Britain in North America, China and South Korea in Asia.

Broadly speaking, blockchain technology is a new distributed infrastructure and computing method that uses block chain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automatic script code to program and operate data.

What is a blockchain? From the perspective of science and technology, blockchain involves many scientific and technological issues such as mathematics, cryptography, Internet and computer programming. From the perspective of application, in short, blockchain is a distributed shared ledger and database, which has the characteristics of decentralization, non tampering, leaving traces in the whole process, traceability, collective maintenance, openness and transparency. These characteristics ensure the "honesty" and "transparency" of the blockchain and lay a foundation for the creation of trust in the blockchain. The rich application scenarios of blockchain are basically based on blockchain, which can solve the problem of information asymmetry and realize cooperative trust and concerted action among multiple subjects.

Blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism and encryption algorithm. Blockchain is an important concept of bitcoin. In essence, it is a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks associated with cryptographic methods. Each data block contains a batch of information of bitcoin network transactions to verify the effectiveness of its information (anti-counterfeiting) And generate the next block.

In fact, the word blockchain does not appear in the original English version of bitcoin white paper, but the chain of blocks. In the Chinese translation of the earliest bitcoin white paper, the chain of blocks was translated into blockchain. This is the earliest time when the Chinese word "blockchain" appeared.

The state Internet Information Office issued the regulations on the management of blockchain information services on January 10, 2019, which will take effect from February 15, 2019.
