『一』How does Bytom allow multiple assets to circulate on the public chain platform!

The Internet has "bititized" two major symbols of human civilization - text and currency. However, the copyright is still unclear and vulnerable to attack. Information exchange and wealth circulation still rely heavily on centralized organizations, such as Credit granting and credit reporting services.

The underlying logic of Blockchain is to store information in a joint competitive accounting method. Each page of the encrypted ledger is equivalent to a "block", and the transaction review results are stamped with indisputable Tampered timestamps are stored throughout the entire network. This "distributed ledger technology" brings equity ownership and mutual trust among strangers, and brings the dawn of free trading of assets.

As the underlying technology of Bitcoin, why has blockchain become the biggest hit in financial technology? As of June 18, 1 Bitcoin is equivalent to approximately 18,750 yuan, the total market value of global digital assets has exceeded 110 billion US dollars, the types of digital assets have reached 4,321, and there are more than 40 digital currencies with a market value of 100 million US dollars; then, The free circulation between coins, between chains, between digital currencies and legal currencies, and between physical assets and bit assets has become a huge pain point. How can we build a bridge for assets to jump from the atomic world to the bit world? ? Artificial intelligence (AI) is equally hot as blockchain. What kind of sparks will the combination of the two create? This article tries to explain.

1. The blockchain industry is in full swing, and the “comparative advantages” of domestic entrepreneurs are highlighted

Blockchain was developed by Satoshi Nakamoto in 2008, when he published the foundational paper "Bitcoin: A "A Peer-to-Peer Electronic Cash System" proposed, and Bitcoin was created by Satoshi Nakamoto to reward participants for competitive accounting, mainly through "Proof of Work, POW" to "mine" and Get a bonus. "Mining" is a process of competing for consensus algorithm capabilities, which requires huge energy consumption. It is worth mentioning that the current four major Bitcoin "mining pools" in the world are mainly concentrated in southwest China and Inner Mongolia.

Any node in the public chain is open. Everyone can participate in the calculations in the blockchain, and everyone can download and obtain the complete blockchain data (all ledgers). As the blockchain itself The security level is improved. In the private chain, many nodes have access rights, and only specific permitted nodes can be publicly accessed.

The emergence of "smart contracts" is to solve the problem of converting legal currency protocols into protocols in the bit world. Smart contracts can accelerate real currency becoming "programmable currency" in the blockchain, and how to use it? Can legal currency be connected to digital currency, thereby connecting the atomic world and the bit world, and promoting the interaction and application of assets between the two worlds? We need “Bytom Chain” to solve this problem.

"Bytom Chain" is created by Babbitt, the largest developer community in the domestic blockchain industry. Compared with other single-asset blockchains, the blockchain interaction protocol of “Bytom” is more suitable for multi-bitAssets such as digital currency, income rights, unlisted equity, debt, etc. perform complex interactive operations based on smart contracts.

China ranks first in the world in the amount of investment in financial technology. Blockchain is a track alongside mobile payment, insurance, etc. BAT has deployed blockchain in the past two years, and the network and Circle (cross-platform) (border payment) reached a strategic cooperation, Alibaba cooperated with Ethereum to develop a financial cloud, Tencent's WeBank provides alliance chain cloud services based on Tencent Cloud, etc. As of the end of April 2017, a total of 455 blockchain companies around the world had raised a cumulative financing amount of US$1.947 billion, and there were 61 domestic blockchain entrepreneur financing companies.

The mainstream proof-of-work mechanism (POW) in the blockchain has been criticized for its narrow application range of "hash" calculations, resulting in a huge shortage of mining machines. Idleness and energy waste; Bytom introduces matrix operations and convolution operations into the mining hash process, making mining machines more friendly to artificial intelligence ASICs. The boom in the mining machine market in the blockchain has stimulated the supply chain of ASIC chips for artificial intelligence companies. Eliminated or idle "mining machines" can also be used for AI acceleration.

Conclusion:

Although blockchain is "brain-burning", it does not affect developers' passion for exploration. This is not only the interest appeal of Bitcoin, but also the desire to truly return to the "Internet of Value" that is free, open, and collaborative. Just as Don Tapscott, the father of the digital economy, compared blockchain technology to the "Aladdin's magic lamp" that opens up a well-off society for mankind, with the opening up of public chain platforms for various currencies, chain areas and traditional financial asset transactions, was born, the bitification of multi-asset is gradually becoming a reality, and can provide open big data, controllable smart contracts, mining machine acceleration for artificial intelligence, the era of currency and free assets predicted by Hayek, and the era of people's investment and Trading assets in the future will be as convenient as online shopping today, and it must be based on the win-win and mutual promotion of artificial intelligence and blockchain technology.

『二』What kind of disruption has the blockchain brought and why can it become a national strategy

< p>The disruptive characteristics of blockchain lie in the following four aspects: 1. Transparency. The data records of the blockchain system are transparent to the entire network nodes, and the update operations of the data records are also transparent to the entire network nodes. This is the basis for the trust of the blockchain system. Since the blockchain system uses open source programs, open rules and high participation, blockchain data records and operating rules can be reviewed and traced by nodes throughout the network, with high transparency.
2. Openness. The blockchain system is open. Except for the private information of the parties directly related to the data, which is always encrypted, the blockchain data is open to everyone (except for blockchain systems with special permission requirements). Anyone or participating nodes can query blockchain data records or develop related applications through public interfaces, so the entire system information is highly transparent.
3. Information cannot be tampered with. Once the information of the blockchain system is verified and added toAfter the blockchain is created, it will be permanently stored and cannot be changed (except for systems such as private blockchains with special change requirements). Unless more than 51% of the nodes in the system can be controlled at the same time, modifications to the database on a single node are invalid, so the data stability and reliability of the blockchain are extremely high
4. Decentralization. Decentralization is the most basic feature of blockchain, which means that blockchain no longer relies on central processing nodes and realizes distributed recording, storage and updating of data. In a traditional centralized network, attacking a central node can destroy the entire system. However, in a decentralized blockchain network, attacking a single node cannot control or destroy the entire network or more than 5% of the nodes in the network. It's just the beginning of gaining control. 2019 is the first year of commercial application of blockchain technology, and favorable policy incentives will make the development of blockchain technology more stable.
As the application of blockchain technology gradually penetrates into many fields such as digital finance and the Internet, everyone has a clearer understanding of the value of blockchain.
Blockchain has formed a global competition situation. All countries are seizing development opportunities, and China cannot lag behind; therefore, it is understandable that blockchain has become a national strategy.

『三』What issues did the first China Blockchain Security Summit Forum focus on?

On June 21, the first China Blockchain Security Summit Forum was successfully held at the National Convention Center in Beijing , the conference was hosted by the China Technology Market Association and hosted by Beijing Zhichuangyu Information Technology Co., Ltd. The conference attracted leaders of many national authoritative institutions, big names in the blockchain industry, big names in the security industry, as well as many top industry media and overseas authorities to participate. .

(Roundtable discussion on blockchain security)

The conference invited more than ten experts in the field of blockchain ecology at home and abroad to deliver keynote speeches. , sharing how to use technology to create a better and safer blockchain ecosystem, as well as innovative applications of blockchain technology. The high-quality topic sharing was also praised and discussed by the guests. In the roundtable forum of the conference, relevant experts also held a focused discussion on how to promote the safe and healthy development of the blockchain industry, and many hot ideas were thrown out.

The first China Blockchain Security Summit Forum has received widespread attention from relevant industries and media. The registration channel for the conference was fully booked just one day after it was opened. The venue was fully occupied on the day of the conference. Hundreds of professional media attended the conference that day and reviewed the conference. The meeting was reported.

『四』 What is the concept of blockchain

Blockchain is a term in the field of information technology.

Essentially, it is a shared database. The data or information stored in it has the characteristics of "unforgeable", "full traces left", "traceable", "open and transparent" and "collectively maintained". . Based on these characteristics, blockchain technology has laid a solid foundation of "trust" and created a reliable "cooperation" mechanism, which has broad application prospects.

On December 2, 2019, the wordSelected as one of the top ten buzzwords in 2019 by "Jiaowenqizi".

Related to blockchain financial applications:

Since 2016, major financial giants have also taken notice and launched blockchain innovation projects to explore the application of blockchain in various financial scenarios. Possibility of applying blockchain technology. In particular, Puyin Group took the lead in pioneering the “blockchain”-based digital currency.

The standard digital currency is an asset that has been identified, evaluated, confirmed, insured, etc. by a third-party organization and written into the blockchain through a rigorous digital algorithm to form a link between the asset and the digital currency. The standard correspondence relationship is called a standard digital currency.

In order to realize the great leap forward development of blockchain finance, in order to promote the new development of China's economy, accelerate the circulation of global assets, and realize the dream of rejuvenation that generations have been striving for, Puyin Group will On December 9, the Puyin Blockchain Finance Guiyang Strategy Release Ceremony was held in Guizhou.

The meeting will discuss the digital circulation of assets through blockchain, the blockchain financial transaction model, and the application of blockchain services and social public industries. This conference will mark the beginning of the application of blockchain finance and the transformation and development of a new financial ecosystem.

『Wu』Who are the representatives of the current blockchain alliance?

In the past two years, blockchain alliances have emerged. Who are the representatives? In the early stages of the development of the blockchain industry, many companies and institutions formed blockchain alliances to share blockchain technology research results and seek broader applications of blockchain technology. In the past two years, blockchain alliances have emerged. As of July 2017, there are currently R3 composed of more than 40 international banks, Hyperledger initiated by the Linux Foundation, and Zhongguancun District, located in the core hinterland of China’s Internet. The Blockchain Industry Alliance, the China Ledger Alliance co-sponsored by 11 institutions, the Golden Chain Alliance jointly established by 25 financial institutions, the Russian Blockchain Alliance known as the "Russian version of R3", and those seeking to integrate with micro-finance Blockchain Microfinance Industry Alliance, Qianhai International Blockchain Ecosystem Alliance led by Shenzhen Qianhai Administration Bureau, and Lujiazui Blockchain Financial Development Alliance located in Lujiazui. When everyone adds fuel to the fire, many institutions and talents join in to promote the vigorous development of blockchain.

『Lu』 Does blockchain really have development prospects?

Blockchain undoubtedly has development prospects, and the necessary condition for development prospects is to enter the mainstream market.

Matt Spoke, founder and CEO of North American blockchain infrastructure The OAN (formerly Aion Network), published an article in Forbes on July 24 titled "In order to successfully enter the mainstream market, blockchain projects must "Eat Dog Food", in which Matt mentioned his views on how blockchain should enter the mainstream market - "Eat Dog Food".

In the technology circle, there is a jargon called "eating dog food"(dogfooding, also known as eating one's own dog food) refers to a company using its own products and becoming a user of its own products. Many high-growth companies (such as Microsoft, Facebook, Amazon, Apple, Netflix and Google) also use dog food to test products or help build credibility for their products. Although "eating dog food" is often used to find and fix bugs, it has another value: creating reliable use cases for the company's products.

This is worth learning from blockchain projects, because blockchain projects often hold the idea of ​​"if it is built, they (users) will naturally come" and habitually create new and interesting things. Responsibility for blockchain applications is given to third parties.

This attitude is so common that even the well-known blockchain summit Consensus 2019 (2019 Consensus Conference) also held a conference titled "Build it, they (users) will naturally come: Creating a global area" Blockchain Center's roundtable forum discusses how governments around the world can make efforts to attract blockchain projects while balancing regulatory, investment and innovation needs.

To be fair, this strategy may be effective for blockchains that only target cryptocurrency circles. For security tokens, especially exchanges that trade such representatives, this makes even more sense - "supply creates demand" is the usual thinking here, especially considering the complex infrastructure required to implement these transactions. .

In contrast, "eating dog food" is more likely to be used by blockchain project developers seeking mainstream audiences (such as those in the financial industry, manufacturing and supply chain, identity management, etc.) use. If blockchain technology wants to break into these mainstream fields, blockchain companies must first "eat dog food." This will not only clearly prove that blockchain technology is feasible outside the currency circle, but also highlight that blockchain can not only optimize existing use cases, but also create new use cases.

The OAN team has always adhered to this concept and relied on the technology stacks of The OAN and Aion built over the years to develop Moves, a financial technology platform for independent workers.

Matt said that when developing the Moves product, the team hopes that the relevant functions of The OAN blockchain network can be fully utilized, so the focus will be on the following three aspects:

p>

1. How to use The OAN blockchain network to improve the credit efficiency of products.

There are two main considerations for improving credit efficiency: 1) Can Zheng Lu learn from the mechanisms of the DeFi market to reduce capital costs; 2) Can blockchain technology be used to increase the external credit process for Moves? of trust. Here, Moves will form a "pooling of wisdom" mechanism, allowing everyone to contribute to reducing credit risks and increasing the credibility of the credit granting process, and may even develop a micro-guarantee mechanism in the future. Therefore, users will be able to act as borrowers, lenders or guarantorsThe Bulgarian party participates in the market established by the platform.

2. How to align the interests of products and users.

Specifically, by connecting Moves to The OAN network, and with the help of the digital asset Aion, a relationship of consistent interests is formed between the product and the user, so that users can experience Moves personally. Whether the product development is successful or not, you can also directly participate in the blockchain network that supports Moves - The OAN.

3. How to create a pioneering financial reputation data open system with Moves.

This open system may become a replacement for traditional credit scores or related mechanisms. For years, banks and financial institutions have used scores from Equifax, FICO or others as risk indicators, and the Moves team believes the product it is building will be a good start - a better, more modern financial system. The beginning of the reputation system. This is a long-term goal.

Moves supports mainstream ride-sharing, food delivery and other gig economy concept platforms in North America and will be the flagship open application developed by The OAN on its blockchain network. In June, Moves' business operations expanded from Ontario to two more provinces - Alberta and British Columbia, and into Western Canada.

The various measures taken by The OAN team are all based on the spirit of "eating dog food" and working hard to allow blockchain technology to enter the mainstream market as soon as possible. Blockchain is not for the niche, but for the mainstream. In addition to The OAN team, many projects and institutions in the blockchain industry are also moving towards this goal. With such an excellent and targeted blockchain, what can you do? Are you saying there is no development prospect?

『撒』 What does Xue Manzi think about blockchain investment?

Xue Manzi "defied" Xu Xiaoping: I am not as excited about blockchain investment as he is.

Don’t touch counterfeit coins that cost just a few cents. Don’t hesitate if you don’t understand a project and only read a few lively words to fool your eyes. You have no reliable entrepreneurial experience. Don’t touch anyone with a reliable entrepreneurial team, and try not to touch anyone without the endorsement of reliable investors. Nowadays, there are too many projects. People are not really using blockchain technology to change the industry and create industry value. Most people come here for the hope of getting rich suddenly. This makes me very worried!

If this industry has such a high possibility of annihilation, why bother investing in the blockchain industry? Despite the huge uncertainties and risks, this blockchain Industry represents the future. As investors, our mission is to use our own capital to promote the great development of an industry and enjoy investment returns at the same time.

The first generation of the Internet revolutionized social functions and searches between people, and the second generation of blockchain technology will completely subvert the way human transactions are conducted. Decentralized and distributed blockchain technology will completely change the existing currency transaction model. It willHumanity's future contribution will definitely exceed that of the Internet back then. It can be said that the future of the blockchain industry is very bright, but the road will be extremely tortuous and the challenges will be unprecedented. Let me say the important thing three times: the market is risky, so be cautious when investing! When investing in blockchain, you must be sentimental and insist on value investing. You must be knowledgeable and able to identify the team. Otherwise, don’t lose the money you have worked hard to save.

Finally, the hot industry will die. There are hot spots every year. Most of them are cannon fodder. Don’t get carried away. Most projects will fail. We look forward to the national regulatory authorities through sandboxes, licenses, legislation, and transactions. The guidance and other measures help small and medium-sized investors filter out junk projects to stabilize the market and help the healthy development of blockchain technology from the financial market level. This is my opinion on blockchain investment.

『8』 How will China promote the development of the blockchain industry in the future?

The blockchain industry is on the eve of an explosion of applications

Blockchain as an underlying technology With the support of policy trends, it is attracting more and more explorations of application implementation. At the 2019 Future Business Ecological Link Conference held recently, Zhu Youping, deputy secretary of the Party Branch of the China Economic Network Management Center of the National Information Center, pointed out that after 11 years of trial and error, the blockchain technology has basically become commercially available, and the industry has now reached an application explosion the night before.

Wu Xiaochuan, a senior expert in blockchain development at Zhongan Technology, told a reporter from the 21st Century Business Herald that the biggest difficulty in implementing the current blockchain industry is how to map the physical world and the blockchain world one by one. This requires a multidisciplinary effort to resolve. Internet of Things technology is an important part of it. With the support of 5G, cloud computing and other technologies, the future will bring more complements and support to the implementation of blockchain technology.

According to analysis agency Tractica, the global enterprise blockchain market will reach US$20.3 billion by 2025.

Key nodes in promoting technology and standards

Compared with other underlying technologies, blockchain has also gone through a relatively tortuous development process. In the integration of multiple technologies and the implementation of its own standards, There is still some way to go in terms of ranking.

In his speech at the aforementioned conference, Zhang Xiaojun, head of Huawei’s blockchain, pointed out that today’s blockchain technology is more like the development stage of the Internet in 2002-2003. If blockchain-related standards can mature in 2020, including cross-chain standards, storage standards, and standard data format storage, large-scale commercial use will be accelerated in 2021.

my country’s blockchain industry is still in its infancy, but with the continuous support of national policies, the continuous advancement of industry technology and the increasing demand in downstream application fields, my country’s blockchain industry is expected to continue to maintain high speed increase. In 2011, the market size of my country's blockchain industry was less than 6 million yuan. By 2018, the market size of the blockchain industry had grown to 67 million yuan, maintaining a rapid growth rate of more than 80%. It is expected that in 2022, driven by policy support and downstream demand, my country’s regionalThe market size of the blockchain industry is expected to exceed 450 million yuan.

“The biggest advantage of blockchain is security. Even financial transactions with high security requirements can be completed here, but The biggest shortcoming is low efficiency." Zhu Youping pointed out to the 21st Century Business Herald reporter that with the technology support of 5G and even future quantum computing, these weaknesses will be quickly made up for.

At the same time, the Qianzhan Industry Research Institute also provides industry big data, Solutions for industrial planning, industrial declaration, industrial park planning, industrial investment promotion, etc.

The significance of the establishment of "Nine" Blockchain Alliance

The 2018 Global Media Blockchain Summit was held on the 19th at the Financial Hall of the Hong Kong Stock Exchange. Many media attending the meeting focused on blockchain Development prospects, industry trends and other issues, they made suggestions on deepening media blockchain cooperation and promoting the healthy development of the industry, and jointly announced the establishment of the Global Media Blockchain Alliance.

According to reports, the alliance will provide an open access mechanism for media members, integrate resources, and create a trustworthy media blockchain platform. At the meeting, the Global Media Blockchain Alliance released the "Hong Kong Initiative", advocating that media disseminate advanced concepts, encourage ecological innovation, and continuously provide high-grade, high-quality information and services in the dissemination of information in the blockchain field.

Yu Guoming, executive dean of the School of Journalism and Communication at Beijing Normal University, pointed out at the summit that only through full development of media blockchain can a more sound and good media ecosystem be formed. Mainstream media must consciously assume social responsibilities in the development of media blockchain and become organizers and builders to promote technological progress and business innovation.

Ding Laibin, secretary-general of the Global Media Blockchain Alliance, said that blockchain technology is expected to bring new changes to society and its healthy development needs to be protected. In terms of public opinion supervision in the blockchain field, the media should give full play to its role in exploring the value of the industry, combating industry fraud, and contributing to the development of the blockchain industry.
