Blockchain public Chain Technology Summit

1.

In the past, when it comes to blockchain, we always think of foreign procts, such as Ethereum. But when I talk about this topic today, I think more about China's own blockchain technology

at present, the mature application of blockchain technology is more concentrated in some public chain projects, because many application projects need to be developed based on this, so I think the current global landing direction is public chain projects, and it is still too early to talk about maturity. After all, bitcoin and Ethereum are still blocked, and many old problems have not been solved, There will be many new problems. The well-known ones are Biyuan chain, ulord (the project is abroad, but the technical party provides it in the domestic company, Hunan Tianhe Guoyun Co., Ltd.), quantum chain, Xiaoyi Neo, gongxinbao, etc

ulord is a point-to-point value delivery public chain. By building the underlying architecture of blockchain and digital resource distribution protocol, it supports third-party developers to build their own applications on top of their open source protocol, and works with many instry partners to build a complete ecosystem of blockchain technology and applications

based on various rules and protocols created by ulord, it is convenient to graft various digital resource application scenarios including text, pictures, music, video, software, etc., providing a direct docking platform for information creators and consumers. Third party developers can build their own economic system in ulord, or focus on building all kinds of applications around ulord, and use the ulordtoken in ulord as the voucher in the system

for example, an experience sharing platform can be built on ulord, where the experience sharers price the published experience, and the people who obtain the experience information trade on the platform, and each fee paid to the experience sharers will arrive at the account immediately; Proct promoters can publish ads on ulord, price ads, and people who are interested in ads can get certain profits by clicking on ads. The first mock exam is to separate information from the past, and to use platform or other centralized organizations to spread profit. This mode eliminates intermediate links, and information providers and consumers directly connect with Ulord, which ensures the maximization of the interests of the originator. p>

Blockchain includes public blockchain, joint (instry) blockchain and private blockchain. Public chain point-to-point e-cash system: bitcoin, smart contract and decentralized application platform: Ethereum

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

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 generated by using cryptographic methods. Each data block contains a batch of bitcoin network transaction information, Used to verify the validity of its information (anti-counterfeiting) and generate the next block

extended data

according to the different degree of blockchain network centralization, three kinds of blockchains under different application scenarios are differentiated:

1. The blockchain with the whole network open and without user authorization mechanism is called public chain

2. The authorized nodes are allowed to join the network, and the information can be viewed according to the authority. It is often used in the inter agency blockchain, which is called alliance chain or instry chain

3. All the nodes in the network are in the hands of one organization, which is called private chain

alliance chain and private chain are also called licensing chain, and public chain is called non licensing chain

blockchain features

1, 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

2. 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

3. 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. Safety. As long as 51% of all data nodes cannot be controlled, the network data cannot be arbitrarily manipulated and modified, which makes the blockchain itself relatively safe and avoids subjective and artificial data changes

5. Anonymity. Unless there are legal requirements, technically speaking, the identity information of each block node does not need to be disclosed or verified, and the information can be transferred anonymously

hope to help you. You can also sign up for this conference

4. At present, the mature application of blockchain technology is more concentrated in some public chain projects, because many application projects need to be developed based on this, so I think public chain projects are one of the major landing directions in the world. It's still too early to talk about maturity. After all, bitcoin and Ethereum are still blocked, and many old problems have not been solved, There will be many new problems. The well-known ones are Biyuan chain, ulord (the project is abroad, but the technical party provides it in the domestic company, Hunan Tianhe Guoyun Co., Ltd.), quantum chain, Xiaoyi Neo, gongxinbao, etc.

5. The public chain, as the name suggests, has great inclusiveness and fairness. The better the public chain project does in these two aspects, the more prominent it will be. At present, many public chains sacrifice fairness in order to speed up the transaction, which is not optimistic. There is a project called Fanta network. Their DSC technology claims to be safe, democratic and fair, which deserves long-term attention. However, their code will not be open source until the end of the year, and the progress needs to be accelerated

Blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Blockchain is an important concept of bitcoin. It is essentially a decentralized 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 a batch of information about bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block

if such technology wants to be put into application, the biggest problem is the "Impossible Triangle problem"

that is, scalability, decentralization and security cannot be achieved at the same time, and only two of them can be achieved

most of the existing public chain projects in the market are difficult to put into use on a large scale

7. Before October 2018, it seems that the fastest one is REBO, next to EOS. After October, these public chains are basically silent in terms of speed, because bitconch of Baker chain has achieved 120000 TPS Based on many technical advantages, which makes it possible for applications to land. Therefore, the world's fastest public chain is the world's fastest public chain, which can be said to be the leader.

On 19, 2018, "global media blockchain summit" was held in the financial hall of the Hong Kong stock exchange. The summit gathered more than 100 global media and dozens of top experts in the instry. At the meeting, we witnessed the establishment of the global media blockchain Alliance (bimg) and the release of bimg Hong Kong initiative, and discussed in depth the development prospect and instry trend of blockchain

member of the journalism and communication discipline evaluation group of the Academic Degrees Committee of the State Council Professor Yu Guoming, executive director of School of Journalism and communication of Beijing Normal University, delivered a keynote speech entitled "the value of mainstream media in the tide of technology" at the "2018 global media blockchain summit"

Yu Guoming said: "for the whole social communication in China and other major countries and regions in the world, including the process of blockchain construction, development In terms of the communication ecology in the process of evolution, the value of traditional mainstream media should also be indispensable. Although its share has really declined worryingly, such responsibility and value bearing are still very important. "

Yu Guoming further pointed out that traditional mainstream media's professional adherence, social status conferring function and local advantages are its great advantages. At the same time, with the development of social development and Internet technology, blockchain is not only a technology, but also a way to reorganize the society to a greater extent. Yu Guoming said: "in the words of Marx a hundred years ago, it is a technological form on top of such a new Internet technology as" Free Alliance of free people. ". To a large extent, it is a new form of social evolution after the Internet technology activates the indivial. Such a new form needs the mainstream media to play an important role in it, because in the process of such a new social evolution as blockchain, it is embodied in the so-called emergent evolution in system science, that is to say, the micro force and micro value released by Internet technology is a qualitative change in the development process and direction, which is a kind of social development A qualitative turning point in the development of the field, instry and market. "

in the presence of all guests, the global media blockchain Alliance (bimg) was officially established at the meeting. Ding Laibin, Secretary General of the alliance, pointed out in his speech that the blockchain is really using the mechanism to let people see some changes that may occur in the future, and these changes may subvert the current state and make the social efficiency leap forward. In this process, the media function can not be absent, should play a supervisory role, exert a strong media supervision role, let investors distinguish right from wrong

Ding Laibin said: "the media is the public knowledge and conscience of the society and the supervisor of the development of the instry. To play this role well, we should be close to the game and stand where we can hear the gunfire. Therefore, if there is still a little distance between traditional media and blockchain before, let's eliminate this distance at today's summit. The listing of any enterprise is not the end, but the starting point. It is the same for many blockchain projects. From the beginning to the development, it also needs a lot of disclosure and planning, so that the enterprise can be presented to all the public and investors without reservation. It should be open and transparent, from the beginning to the end. Only in this way can the instry grow more healthily and more rapidly. "

in the bimg Hong Kong initiative released at the event, Ding Laibin called on the media to join hands and make joint efforts to create a fair, just, honest, dynamic, harmonious and orderly instry public opinion environment; At the same time, the media should be encouraged to be open and inclusive, advanced in communication, and ecological innovation in information dissemination in the blockchain field, so as to continuously provide high-grade, high-quality information and services

9. Yes, that's right. It's chain digging

10. Generally speaking, the competition of blockchain public chain is fierce now, because the public chain project is the foundation of blockchain ecology, and the public chain is a super project with huge system, extremely complex and extremely difficult. At present, the overall market situation is similar to that in the early days of the computer system, which started with the development of technology; Linux operating system and UNIX (Younis) are changing, but in the end, windows dominates and apple OS coexists for a long time< br /> 
at present, Ethereum and EOS are the most popular public chains. However, the market value of EOS has plummeted after its epic loophole recently, which has been downplayed by many media. Often the most promising at the beginning may not win in the end. Recently, because of their innovative consensus algorithm, they proposed quite innovative CPOs and focused on a new public chain project

their name is gaiaworld public chain, and their CPOs consensus algorithm is their core technology. Specific technical details can go to the official website to see the white paper, in short, TPS speed has reached a new height, faster than Ethereum, and can support the layout of large projects< br /> 
at the same time, they have innovated two other technologies. Parallel chain technology can make it easier for other developers to release side chains, and then aegis protocol, which is a specific smart contract protocol&# 160;< br /> 
now there are so many air projects, it's really hard to distinguish the good from the bad, but I think the technology platform is the future
hope to adopt
