Blockchain Internet conversation video

1.

Because the design of blockchain is a kind of protection measure, such as distributed computing system with high fault tolerance. Blockchain makes hybrid consistency possible. This makes blockchain suitable for recording events, titles, medical records and other activities that need to include data, identity management, transaction process management and provenance management. Blockchain has great potential for financial disintermediation and has great influence on guiding Global trade

extended data :

1. Blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system

2. Blockchain is an important concept of bitcoin, which is essentially a disintermediated database and 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

3. Blockchain - the original blockchain is a kind of decentralized database, which contains a list called blocks, with continuously growing and orderly records. Each block contains a time stamp and a link with the previous block. The block chain is designed so that the data can not be tampered with. Once recorded, the data in a block will be irreversible

2. The company that J Luo cooperates with is self sell, the first personal asset platform in the world. The founder is Yuan Li. It seems that his name is probably a Chinese
selfsell launched j-rowjames Rodr í Guez's token, J Luo's cryptocurrency is called jr10 token, Jr is his initials, 10 is his jersey number, this cryptocurrency will be on sale on June 12 this year
selfsell token is SSC, now it can be traded in okex and lbank
more can be online, thank you

3. Block chain + content refers to the application scenario of content instry that is activated by block chain technology, while Internet plus content refers to the concept of expanding content domain based on Internet. The difference between the two is that the former relies on the blockchain for content valuation, which can make the content valuable. The latter only uses the characteristics of the Internet to spread the content, and does not support content payment. Speaking of this, we have to give Amway a blockchain project named Aqua oxyhydrogen, which belongs to the content public chain. I hope it can help you.

4. In essence, blockchain is a decentralized ledger system, which has the characteristics of decentralization, openness, non tampering information and programmability. It can be used as the underlying storage and transmission protocol of value Internet. Blockchain is expected to lead us from personal trust and institutional trust to the era of machine trust. Consensus mechanism is the core of regional chain construction. Digital currency is just the beginning. Blockchain can change more, reshape the world's trust system, and solve many problems of high trust cost in the past
there is a core difference between blockchain and Internet: the value of underlying protocols and upper applications of blockchain and Internet are completely reversed. It mainly comes from the two core features of blockchain:

the first feature is that zero knowledge proof changes the ownership of data. In other words, the user's personal data on the blockchain belongs to the user and does not need to be provided to the application and stored on the central server. Then the core support "data" behind the market value of Internet application layer services, such as bat, will lose its original value in the field of blockchain
another feature is the economic incentive model brought by token, which gives high value to the underlying protocol. In the Internet era, no one pays for HTTP protocol, no one pays for sending and receiving email, and no one pays for Google's search service.

5. An account book supervised by many people can be traded on it, and no one can default on it, because if one person makes a fake, others can point it out.

6. In my opinion, the biggest difference between traditional blockchain projects and blockchain content projects is that the latter uses blockchain technology and combines content output mode to help content procers protect right, expand publicity and explore content value. For example, aqua hydrogen oxygen content public chain project can help content procers expand content value in their procts. The subject can download the DAPP of aqua project for learning. I hope it works for you.

7. One of the characteristics of blockchain is to realize irreversibility through distributed ledger technology, and at the same time, various technologies such as ring signature and zero knowledge proof are used to realize anonymity and privacy protection. Social networks are monopolized by Facebook, instant messaging is monopolized by WhatsApp and other centralized procts. They bring incomparable communication convenience to users, greatly improve the frequency and efficiency of communication between people, and bring convenience to billions of people all over the world

through the blockchain, communication services can organize the operation of communication services without the mode of central enterprise. In the future, blockchain should have a real impact on real life, not just by concept and hype, but by real landing procts. What is really landing procts is procts that can meet the needs of users. If the existing centralized procts can well meet the needs of users, then the decentralized procts will not have enough substitution effect, and can not be truly implemented

the protocol layer of blockchain mainly includes four aspects: network programming, distributed algorithm, encrypted signature and data storage technology
the ability of network programming is the main factor for us to choose a programming language, because distributed algorithm is basically the implementation of business logic and can be achieved in any language. The encryption signature technology is directly and simply used, and the database technology is mainly used. Only the implementation of point-to-point network and concurrent processing is the difficulty of development. Therefore, for those languages with strong network programming ability and simple concurrency processing, people especially prefer them

users get the initial number of tokens for free. Some of its practical use scenarios:
1. Encrypted video chat: multinational users want to have video chat, only when both sides hold a certain number of SKM can they achieve encrypted video chat
2. Large capacity file encrypted transmission: the file transmitted by one user to another user exceeds the size limit, and the sender must hold a certain token to realize encrypted transmission
3. Conversation information saving: conversation records can be saved as long as both parties agree, and both parties need to hold a certain amount of tokens
4. Retransmission reminder: if a user sends a file to another user, but he doesn't want the other user to share it, the user can use a certain token to be notified when the file is retransmitted
5. Secret key unlock file: one user transfers the secret key file to another, and only the other party is allowed to view it. The sending user can use the token to let the other party receive the fragmented file. Only by getting the secret key from the sender can the file be unlocked<

the Xueshuo innovation blockchain Technology Workstation of Lianqiao ecation online is the only approved "blockchain Technology Specialty" pilot workstation of "smart learning workshop 2020 Xueshuo innovation workstation" launched by the school planning, construction and development center of the Ministry of ecation of China. Based on providing diversified growth paths for students, the professional station promotes the reform of the training mode of the combination of professional degree research, proction, learning and research, and constructs the applied and compound talent training system.
