1. blockchain does not belong to any instry. Blockchain is a new application mode of computer technology, such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and so on. In a narrow sense, blockchain is a kind of chain data structure that combines data blocks in a sequential way according to the time sequence, and it is a distributed account book that can not be tampered with and forged by means of cryptography.
2. Let's take bitcoin as an example:
blockchain is an important concept of bitcoin, which is essentially a decentralized database and serves as the underlying technology of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block
blockchain is public on the network and can be queried in every offline bitcoin wallet data. The function of bitcoin wallet depends on the confirmation with the blockchain. An effective inspection is called a confirmation. Usually, a transaction needs to obtain several confirmations. The lightweight bitcoin wallet uses online confirmation, that is, it will not download the blockchain data to the device storage
many of bitcoin's competitors also use the same design, but the workload proof and algorithm are slightly different. For example, the use of proof of interest and scrypt and so on
in addition, digital cryptocurrencies such as Laite coin, Ethereum, Weimeng coin, doggy coin and Ruitai coin also use blockchain technology.

3. Blockchain has the following characteristics:
decentralization. Blockchain technology does not rely on additional third-party management institutions or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes information self verification, transmission and management through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain
openness. Blockchain technology is based on open source. In addition to the private information of all parties involved in the transaction is encrypted, the data of blockchain is open to everyone. Anyone can query blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent
independence. Based on consensus specifications and Protocols (similar to various mathematical algorithms such as hash algorithm used by bitcoin), the whole blockchain system does not rely on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention

4. I have summarized the following two characteristics:
1. Block chain technology is a decentralized consensus mechanism to maintain a complete, distributed and tamper proof ledger database. It can enable the participants in the blockchain to achieve a unified ledger system without establishing a trust relationship. 2. Renren blockchain technology service platform does not need to develop one click to create its own blockchain system to quickly build blockchain infrastructure; One click to complete the development and deployment of blockchain applications; To provide your customers with open, transparent and credible services.

5. 1 - disintermediated trust, which has been repeatedly emphasized, is not decentralization but disintermediation
2-stability, reliability and persistence. Because it is a distributed network architecture, no central node can be attacked or attacked, it has stronger stability, reliability and persistence in the overall technical layout
3-strong security, consensus mechanism does not need the entry of a third party, but through one technology to achieve the completion of the whole transaction
4 - the transparency and non tamperability of the transaction
the above four points are the characteristics of blockchain technology application analyzed by Chongqing jinwowo group.

6. The application of blockchain technology in life has just started, but the changes it brings are very huge. This kind of change comes from all aspects, and will have an important impact on our ordinary people's lives
"now the college entrance examination is a lifetime, but if we use the form of blockchain, we can record all the learning records and extracurricular activities of a child from the age of six to the college entrance examination. So the examiners of the college entrance examination don't need to pass an exam or an interview to decide the selection of talents. They can decide what kind of talents they want through all their records. "
about the application of blockchain technology, Qin Yi, partner of Deloitte global financial services, said when introcing it to Jinping media
as for blockchain, more explanations in China still stay at the conceptual level, and there is no really large-scale popular application in China, so we have to say that blockchain still keeps a certain distance from the public. In this interview, I believe it can help you have a deeper understanding of blockchain
blockchain is disintermediation
blockchain, and many explanations are decentralization. Different from the general explanation. "It's not decentralization, it's disintermediation," says Qin
because data is distributed in a distributed way, there is a strong security mechanism in it. Qin Yi said: "because no matter which server is serving, the entire data storage is not easy to detect. But most importantly, because of the reliability of the data, we don't need an intermediary to prove who you are, but rely on a record that we can trust each other to promote any transaction in our life
in her opinion, blockchain is actually a database, but when storing data, it has its own characteristics, such as security, integrity, authenticity, non tamperability, etc
for this technology, Qin Yi concluded: such technology will bring earth shaking changes to life
how to embody the commercial value
compared with foreign blockchain technology, domestic blockchain technology is still in a stage of popularization and cognition. What kind of business value will the future blockchain bring us? Looking at the progress abroad, maybe you can see some possibilities
"two weeks ago (on 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 and track the investment behavior of its clients. Strengthen the understanding of customers. In order to meet the regulatory requirements of Europe, they have successfully completed the validation model through the efforts of the past three months. "
a Deloitte executive also said that if this technology can be applied, it will greatly rece the transaction costs of the instry
Deloitte also published a report in 2016, saying that 2016 will be the first year for blockchain to move from laboratory to real life. Bubi (Beijing) Network Technology Co., Ltd. (hereinafter referred to as Bubi) is a leading blockchain technology service provider in China. Since its establishment, Bubi has been focusing on the R & D and innovation of blockchain technology and procts. It has a number of core technologies, and has made substantial innovation in many aspects, forming a number of core technology achievements, such as mathematically proven distributed consensus technology, distributed consensus technology, and so on Fast large-scale account book access technology, multi chain general ledger technology supporting business form expansion, interconnection technology between heterogeneous blockchains, etc. We have developed our own blockchain basic service platform, which has been applied in equity, supply chain, credit and other fields. Bubi has been committed to building an open value circulation network with the core of decentralized (polycentric) trust, so that digital assets can flow freely
with the in-depth development of many companies, the effect of blockchain technology on the life of ordinary people is becoming more and more obvious.
