Introduction to Ma Yun's blockchain

1.

blockchain is an important concept of bitcoin. It is essentially a disintermediated database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains the information of a bitcoin network transaction, which is used to verify the effectiveness of its information (anti-counterfeiting) and generate the next block

blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies

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 can not be tampered with and forged by cryptography

broadly speaking, blockchain technology uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, and uses cryptography to ensure the security of data transmission and access It is a new distributed infrastructure and computing method to program and operate data by using intelligent contract composed of automated script code

extended data:

the evolution mode of blockchain is as follows:

& 9642; Blockchain 1.0 - digital currency

▪ Blockchain 2.0 - digital assets and smart contracts

▪ Blockchain 3.0 - Implementation of distributed applications in various instries

blockchain features:

1. Disintermediation. Due to the use of Distributed Accounting and storage, there is no centralized hardware or management organization in the system, the rights and obligations of any node are equal, and the data blocks in the system are jointly maintained by the nodes with maintenance function in the whole system

2. Openness. The system is open. In addition to the private information of all parties to the transaction is encrypted, the data of the blockchain is open to all. Anyone can query the blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent

3. Autonomy. Blockchain adopts consensus based specifications and Protocols (such as a set of open and transparent algorithms) to enable all nodes in the whole system to exchange data freely and safely in a de trusted environment, so that the trust in "people" is changed into the trust in machines, and any human intervention does not work

The information can not be tampered with. Once the information is verified and added to the blockchain, it will be stored permanently. Unless more than 51% of the nodes in the system can be controlled at the same time, the modification of the database on a single node is invalid. Therefore, the data stability and reliability of the blockchain are extremely high

5. Anonymity. Because the exchange between nodes follows a fixed algorithm, the data interaction does not need to be trusted (the program rules in the blockchain will judge whether the activity is effective). Therefore, the counterparties do not need to make the other party trust themselves by disclosing their identities, which is very helpful for the accumulation of credit

2. I'll go. Ma Yun has something in his head

3.

block chain is still in the very early stage. At

NPC and CPPCC sessions, Robin Li's speech focused on the open platforms such as PaddlePaddle, DuerOS and Apollo, and the automatic driving of the network. In addition to the Internet and technology, the big guy also talked about the issue of banning smoking related to life and environment, and proposed to carry out the promulgation of national tobacco control regulations

in October 2017, Internet Finance officially joined the hyperledger open source project of Linux foundation, and other core board members include IBM, Intel and JPMorgan Chase

Ma Yun: I want to know what bitcoin can bring to the society

at the two sessions, Ma Yun... Oh, sorry, Comrade Ma Yun who doesn't want to wear a red hat didn't attend the two sessions

then, let's review the comments made by Ma Yun when commenting on bitcoin:

"I'm not very interested in bitcoin. What I want to know is what can bitcoin bring to society? In other words, I think bitcoin technology is very powerful, but we have to be very careful with bitcoin. "

although Ma Yun was very cautious about bitcoin, he also said that he did not understand bitcoin. However, as for "bitcoin technology" or "blockchain", Ma Yun's view is "very powerful"

4. As a coquettish among entrepreneurs, Lao Ma is committed to internationalizing Ali. Blockchain is now internationally recognized as the foundation of the fourth instrial revolution. He will naturally lay out new fields and make long-term plans for Ali. Although the current technology is not mature enough, but dig chain network and major media reports on this aspect are endless. This shows that the instry has great potential in the future.

In November 2017, Alibaba, ant financial services and xiong'an signed a strategic cooperation agreement to build a "digital xiong'an blockchain implementation platform". At present, ant financial services has provided blockchain landing application technology in the rental field in xiong'an. It can be said that xiong'an has become the first pilot field of Ali in the overall implementation project of blockchain technology

6. QQ coin is a kind of virtual currency issued by Tencent in order to facilitate users to purchase the virtual goods and services it provides. Its official price is: 1q coin = 1 yuan. However, if the amount of recharge is large, there will be a certain amount of discount on some recharge platforms
it should be noted that this is the recharge price. If it's selling q-coin, because q-coin recycling is now done by some third-party platforms, there will be a certain cost. Therefore, the recovery price of Q coin is generally lower than the recharge price, remember!

7. 50btc is good, btcguild can't play in China now

8. No one certifies what you said, and Alibaba itself is the pioneer of blockchain technology in China
