How about block global public chain

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>

2. We can only talk about domestic examples. High quality application platforms such as the blockchain rental platform in xiong'an New District of Hebei, the blockchain government affairs platform in Chongqing, and the SMIC blockchain public service platform in Changsha of Hunan are the first to lead into the era of blockchain 3.0.

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

in 2019, the market scale of China's blockchain instry will reach 1.2 billion yuan

in 2016, the market scale of China's blockchain instry will be about 100 million yuan, and it will grow to 1 billion yuan by 2018.
in 2019, the scale of China's blockchain instry will grow steadily, with an instrial scale of about 1.2 billion yuan. With the attention and attention of local governments, it is estimated that by 2022, the market scale of China's blockchain core procts and solutions and related derivative instries will reach 10 billion yuan

from the research results, in terms of consensus mechanism, China's consensus mechanism graally moves from single algorithm to mixed consensus; In terms of cryptographic algorithms, cryptographic algorithms such as secure multiparty computation, homomorphic encryption and zero knowledge proof are continuously integrated and applied; The research of cross chain technology and security technology has graally become a research hotspot

from the perspective of blockchain hardware, at present, the world's most important digital currency mining equipment suppliers are all located in China, and only bitmainland, Jianan Yun and Yibang technology occupy more than 90% of the market share

from the perspective of instry application, the financial instry is the instry with the largest number of blockchain technology implementation projects and the richest scenarios, such as supply chain finance, asset certificate aromatization, credit reference and risk control

in 2020, the blockchain instry will be further standardized

in 2020, China's blockchain policy will continue to be favorable, the standard specifications will be more perfect, the instrial scale will continue to grow, the technology will continue to innovate and develop, and the application demonstration effect in key fields will accelerate. At the same time, according to the problems existing in the development of China's blockchain in 2019, CCID blockchain Research Institute puts forward six suggestions: accelerating the formulation of top-level design, establishing and improving the regulatory system, accelerating the innovation and development of core technologies, promoting the third-party evaluation and certification, strengthening the cultivation of professional talents, and accelerating the implementation of applications in various fields

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

the research process of instry technology is constantly advancing

in recent years, the research process of global blockchain technology has accelerated, and the number of instry patent applications has increased rapidly. According to sopat statistics, from 2014 to 2018, the number of global blockchain patents continued to rise, and by 2018, the number of global blockchain patent applications had reached 2966. Among them, the number of patents in China's blockchain in 2018 accounted for 33.33% of the total number of patents in 2014, and increased to 82.1% in 2018

however, despite the continuous development and innovation of global blockchain technology in recent years, there is no universal evaluation standard and system to specify the technical performance, efficiency, scalability, security and other issues of blockchain. On the whole, blockchain technology needs further breakthrough

China's blockchain technology tends to serve applications

in terms of technology, the core of China's blockchain technology is to serve physical applications, while the US blockchain technology is still solving the potential problems of blockchain, which leads to the domestic focus on alliance chain applications, We hope to optimize the blockchain technology to meet the requirements of high concurrency applications; Foreign countries focus on the application of public chain, and carry out the optimization and innovation of core technology according to the characteristics of public chain. In terms of application, domestic blockchain focuses on the application of service instry and tends to be "non currency blockchain"; Most of the U.S. is a public chain, which tends to the circulation of digital assets

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.

8. The main difference between private blockchain and public blockchain is that jinwowo thinks that private blockchain only uses the general ledger technology of blockchain for bookkeeping, which can be a company or an indivial, enjoying the write permission of the blockchain. This chain is not very different from other distributed storage schemes.

you can find a trading website on btc123, and then find their official QQ group on the website. If you add a QQ group, you can receive a lot of messages, but there are also many false messages. You can judge for yourself. Or search QQ group with bitcoin keyword directly on QQ
there is also a discussion area on btc-e. if you want to watch others chat there, the news will be very fast.

10. Two days ago, Zhu Jiawei, the COO of fire coin group, gave a speech at Lakeside University. You can refer to it. He has six predictions for blockchain: 1. Infrastructure will continue to improve; 2. Innovation in blockchain instry will continue to refine and extend; 3. "Blockchain +" will continue to penetrate into various fields; 3; 4. Perfect instry supervision system and popularize instry self-discipline rules 5. Take technology as the king to ensure the landing of more projects and drive the sustainable prosperity of many instries.
