① Continuing education: The most fundamental feature of the blockchain network

The most fundamental feature of the blockchain network is the blockchain. Its core idea is decentralization. The biggest subversion of the chain is the establishment of credit, and the collective maintenance of the blockchain can reduce costs. Public Blockchain Network A public blockchain is a blockchain that anyone can join and participate in, such as Bitcoin. Disadvantages may include the large amount of computing power required, little or no privacy for transactions, and weak security.
1. Blockchain is a serial transaction record that uses cryptography to connect and protect content. It is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, and encryption algorithms. As an important concept of Bitcoin, blockchain is essentially a decentralized database. As the underlying technology of Bitcoin, it is a series of data generated using cryptographic methods.

② Principles of Blockchain Technology

The application of Blockchain technology in life has just begun, but the changes it has brought are very huge. This change comes from all aspects and will have an important impact on the lives of ordinary people.

“The current college entrance examination determines life for a lifetime, but if we use blockchain, we can record all the learning records and extracurricular activities of a child from the time he enters school at the age of six to the college entrance examination. Then The examiner of the college entrance examination does not need to pass a test or an interview to determine the talent selection, but can decide what kind of talent he wants through all their records."

Regarding the application of blockchain technology, Qin Yi, Deloitte Global Financial Services Partner, said this when introducing it to Jinping Media.

Regarding blockchain, most of the explanations in our country are still at the conceptual level, and there has not really been a large-scale popular application in China. It has to be said that blockchain still maintains its relationship with the public. A certain distance. In this exclusive interview with Qin Yi, I believe it can help you have a deeper understanding of the blockchain.

Blockchain is disintermediation

Blockchain, many explanations are decentralization. Different from the general explanation. Qin Yi said: "It is not decentralization, but disintermediation."

Because the data is distributed in a distributed way, there is a strong security mechanism in it. Qin Yi said: "No matter which server is serving, the entire data storage is not easy to detect. But the most important thing is that because of the reliability of the data, we do not need an intermediary to prove who you are, but rely on A record that can be trusted by each other to facilitate the occurrence of any transaction in life.

In her opinion, the blockchain is actually a database, but when storing data, it has its own characteristics, security sex, integrity, authenticity, non-tamperability, etc.

For this technology, Qin Yi concluded: Such technology will bring about earth-shaking changes in life.

How is commercial value reflected?

Compared with foreign blockchain technology, domestic blockchain is still at a stage of widespread awareness. What kind of business value will blockchain bring us in the future? Look at the progress abroad and maybe you can see some possibilities.

“Two weeks ago (that day was April 20), Bank of Ireland and Deloitte jointly issued a statement. Three months ago, Ireland’s International Investment Banking Department asked Deloitte to help design a way to track the investment behavior of its clients. . Strengthen understanding of customers. In order to meet European regulatory requirements, after three months of hard work, they have successfully completed the validated model."

A Deloitte executive also said that if this A technology can be applied that will significantly reduce industry transaction costs.

Deloitte also released a report in 2016, saying that 2016 will be the first year when blockchain moves from the laboratory to real life. Bubi (Beijing) Network Technology Co., Ltd. (hereinafter referred to as Bubi) is a leading domestic blockchain technology service provider. Since its establishment, it has been focusing on the research and development and innovation of blockchain technology and products, and has a number of core technologies. It has made substantial innovations in many aspects and formed a number of core technical achievements, such as: mathematically provable distributed consensus technology, fast large-scale ledger access technology, multi-chain general ledger technology that supports business expansion, and heterogeneous ledger technology. Construct interconnection technology between blockchains, etc. It has developed its own basic blockchain service platform, which has been applied in equity, supply chain, points, credit and other fields. Bubi has been committed to building an open value circulation network with decentralized trust as the core, allowing digital assets to flow freely.

With the in-depth development of many companies, blockchain technology has made more and more obvious changes in the lives of ordinary people.
