Ⅰ What kind of technology is "blockchain"
What kind of technology is "blockchain" Blockchain is an important concept of Bitcoin The "2014-2016 Global Bitcoin Development Research Report" released by Huobi, Tsinghua University PBC School of Finance's Internet Finance Laboratory and Sina Technology mentioned that blockchain is the underlying technology and infrastructure of Bitcoin. It is essentially a decentralized database and serves as the underlying technology of Bitcoin. Blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a Bitcoin network transaction and is used to verify the validity of the information (anti-counterfeiting) and generate the next block. .
In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-forgeable. Account book. Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, uses cryptography to ensure the security of data transmission and access, and utilizes automated Smart contracts are composed of scripts that program and compute data in a new decentralized infrastructure and normalize computing.
Domestic blockchain application platforms include an asset custody system based on blockchain technology jointly developed by the digital currency crowdfunding platform Biying China, China Post and IBM.
Blockchain is a decentralized, distributed ledger system participated by nodes. The data stored on it cannot be forged or tampered with, and is open to the public. Transparent, the information and value recorded by each account at any point in history can be found on the blockchain. The characteristics of the blockchain protocol provide the necessary foundation for the execution of smart contracts. The contract can be automatically executed and trusted according to established conditions without the need for auditing by any centralized organization.
Blockchain technology is the underlying core of the Bitcoin system. Its essence is a decentralized ledger. When people conduct transactions through the Internet, a new transaction will be recorded on the ledger, and this ledger is A decentralized ledger is jointly maintained by everyone on the network. People can see ongoing transactions at the same time, and control is not in the hands of institutions or individuals. Transactions cannot be tampered with or forged, and they will be permanently stored in the ledger.
For example, the Tongxin Huzhu blockchain mutual aid platform has four major characteristics in applying blockchain technology:
Openness and transparency
Openness and transparency, once all information recorded on the blockchain is recorded, it will be very It is difficult to tamper with and cannot be hidden, and users can check it at any time.
Democratic decision-making
Bottom-up decision-making, the blockchain proposes a variety of different consensus mechanisms to help users effectively form bottom-up decisions and jointly participate in majordecision making.
Accurate execution of rules
Accurate execution of rules. The smart contract technology defined on the blockchain converts all rules into public and clear codes, which can be executed accurately and accurately. Once anyone is identified Cannot intervene.
Never downtime
Never downtime, the blockchain based on the public chain is not affected by any organization or individual. As long as the incentive mechanism is effective and the Internet exists, the blockchain will exist.
What is blockchain? Blockchain is a decentralized shared accounting technology that allows all parties involved to establish a trusting relationship at the technical level. Blockchain can be roughly divided into two levels: one is the underlying technology of the blockchain; the other is the upper-layer application of the blockchain, that is, the transformation, optimization or innovative application based on the blockchain. Blockchain is still in its infancy. Many people have discussed with me how we can ensure both rights and privacy at the same time. Of course, we are just exploring now. We need fair content across the entire network and clear protection. This is what I can only say. So far, this is my arrangement for the future.
Blockchain concept? The idea of blockchain is to be completely decentralized and rely on decentralized justice. In that case, theoretically the cost will drop a lot, proving that real assets and property rights can directly correspond to each other on the Internet. It has solved the problems of decentralization and asset ownership that were not solved by the first generation of Internet information. How big a role does big data play in financial innovation now? Only by registering big data can we know who it belongs to. In fact, this has always been a problem that we cannot solve now. This is not a small problem. If there is a technology in the capital market that makes the property rights of things that were originally unclear clear, that will be a big problem for us. The entire market is undergoing a huge transformation.
What is blockchain? Blockchain technology itself can solve data ownership, pricing and sharing mechanisms. This still cannot completely solve certain problems. To give a simple example when it comes to user privacy, I have a piece of data placed on the machine. The partner comes over and makes an insurance analysis to analyze the cooperation. There is a risk here. Or not, can we deal with it or clarify the property rights of the laboratory, and then clarify the processing rights and data rights. The common products produced by everyone are common to everyone. If we need to divide different things, how to price them and how to divide them? In addition to the technology of blockchain and a decentralized database, when it comes to the above mentioned tasks, it is another issue, and then there is the issue of pricing and the market mechanism. All fields have proven to recognize this rule, so this I think blockchain is a very good core technology, but it cannot cover all problems.
Introduction to Bubi Blockchain
Bubi Blockchain is mainly positioned to provide commercial-grade blockchain infrastructure services, which mainly includes building a blockchain system and building on top of the blockchain system. A support system with high expandability. And on top of this support system are people from all walks of life.application. Bubi focuses more on the underlying technology of the blockchain. In the past three years or so, a team of more than a dozen people has devoted almost all their energy to the research and development of the underlying technology. The reason why Bubi Blockchain chooses points has something to do with the market's promotion method. As we all know, blockchain is a technology that is very suitable for the issuance and trading of digital assets. Points are a digital asset that is naturally legal and compliant, and has a small impact because of its small amount. Therefore, it is a very suitable choice to use points as your first attempt at digital asset issuance. Issuing points based on the blockchain can indeed bring great help to the circulation and mutual exchange of points.
What is blockchain? The application of blockchain technology in the field of property transfer is only one aspect. In addition to reducing property transfer costs, blockchain technology can also be applied to various fields involving company stocks, financial derivatives, and points programs of commercial institutions. The blockchain community is currently focusing on promoting the wider application of this technology in the field of financial assets. Relatedly, various platforms that are still under development have also received very considerable investment.
Blockchain concept? Structurally or by definition, these things are very different. The U.S. dollar, or any currency, from a typical definition, is primarily used as a medium of exchange or store of value for economic activities. Within the geographical scope where a certain currency circulates, people in the region reach a consensus on the use of this currency, making it convenient for everyone to use the same currency to purchase goods or services (the function of currency as a medium of exchange). There is a responsibility to manage the currency through monetary policy in order to ensure the preservation of the value of the currency and avoid the occurrence of inflation (the store of value function of currency). In today's world, almost everyone uses some form of currency in their daily lives.
What is blockchain? Even developers within the blockchain community often easily overlook the big picture mentioned above. There are many competitive projects in the blockchain community, and they are also full of various disputes about the evolution direction of blockchain technology. Over time, some projects in the community will be successful, and others will not be so lucky. Things will not always develop in the direction we expect, but no matter how these projects in the early blockchain community develop, one thing is very clear, that is, blockchain technology has brought us at least A revolutionary function: Blockchain technology will greatly reduce the cost of financial property transfer, and blockchain will be used to control, manage and transmit financial property.
What is blockchain? Blockchain concept? After a certain application analysis, we return to the starting point. The definition of this blockchain technology will surely become more and more abundant with the expansion of applications, and people will discover more mysteries of blockchain technology.
Blockchain is an important concept of Bitcoin. It is essentially a decentralized database and serves as the basis for Bitcoin. underlying technology. Blockchain is a series of data blocks that are associated using cryptographic methods.A data block contains information about a Bitcoin network transaction and is used to verify the validity of the information (anti-counterfeiting) and generate the next block.
The blockchain is public on the Internet and can be queried in every offline Bitcoin wallet information. The functionality of a Bitcoin wallet relies on confirmation with the blockchain, and a valid check is called a confirmation. Usually a transaction requires several confirmations before it can proceed. The lightweight Bitcoin wallet uses online confirmation, which means it does not download the blockchain data to the device storage.
Many of Bitcoin’s altcoins also use the same design, but are slightly different in proof of work and algorithm. For example, using proof of stake and SCrypt, etc.
Blockchain timestamp service and proof of existence
This concept was proposed in Satoshi Nakamoto’s white paper [1], who created the first block, the “genesis block”.
On January 3, 2009, Satoshi Nakamoto, the founder of Bitcoin, left an unchangeable sentence in the genesis block:
“The Times 03/Jan/2009 Chancellor on brink of second lout for banks (on January 3, 2009, the chancellor was on the verge of implementing a second round of bank bailout)."
It was then that the British chancellor Darling was forced to consider a second bailout of the banks. In a time of crisis, this sentence was the headline of a front-page article in The Times that day.
With the blockchain’s timestamp service and proof of existence, the time when the first blockchain was created and the events that were happening at that time are permanently retained.
The Bitcoin company BTCC launched a service "Millennium Chain" in 2015, which is a blockchain engraving service, which uses the above principles. Users can engrave text on the blockchain through this service and store it permanently.
Bitcoin, Litecoin, Ruitai Coin, and Qianjin Card are all digital currencies based on blockchain technology.
Chongqing Jinwowo analyzed: Blockchain is actually a decentralized distributed ledger database.
How popular is blockchain technology?
Blockchain technology makes DAC possible. DAC is something that can fundamentally subvert the organizational model of human society. I believe that its impact on society will surpass the Industrial Revolution and become the most profound change that the Internet has brought to the world.
The essence of blockchain technology is a method of data storage, transmission and certification that is decentralized and contained in a distributed structure. It replaces the current Internet with data blocks (Block). The road's reliance on the central server enables all data changes or transaction projects to be recorded on a cloud system, theoretically achieving self-certification of data during data transmission.
Blockchain technology can be applied to many industries:
Art industry
Ascribe allows artists to use blockchain technology to declare ownership, issue numberable, and secure editions of their works, and can target any Digital form of type artwork. It even includes a marketplace where artists can buy and sell through their website without the need for any intermediary services.
Legal Industry
BitProof is the most advanced of the many document timestamp applications that have emerged in recent years, and will make traditional notarization methods a thing of the past. Compared with free versions including Blocksgin and OriginStaemp, BitProof provides more services, including one for intellectual property rights. Interestingly, BitProof recently collaborated with a San Francisco IT school to put all their students’ academic certificates on the blockchain, completely redefining how diplomas and student certificates are processed and used.
Development Industry
Colu is the first company to allow other companies to issue digital assets. They can "tokenize" various assets and have a profound impact on many people. Although the free Bitcoin wallet Counerparty also allows simple tokens to be issued and traded among other wallet holders, Colu tokens can be configured in various states and types, and can leave and return to the system. , and when storing data on the blockchain is too large, the data can be stored on the BitTorrent network.
Internet Mutual Aid Industry
Tongxin Mutual Aid is the first blockchain online mutual aid platform to be implemented and applied. Technically, through blockchain and big data technology, it eliminates the shortcomings of the traditional online mutual aid model. Establish an open and transparent new online mutual aid platform.
Aite Cat is a virtual pet game produced under blockchain technology. This virtual cat is similar to Internet Letts Dog, 360 pet cat, and NetEase’s Planet are all the same type of blockchain virtual products. The difference between Aite Cat is that the entire cat design uses a 3D three-dimensional effect, making the cat’s The display is no longer a single picture, allowing the cat to move, which increases the fun of the cat.
What technology is the Huangbao blockchain system?The Huangbao blockchain is a powerful decentralized loop intelligence system. The Huangchain chain is referred to as HUANG. It is the first to be used in financial services, advertising media, games and entertainment, various life applications and other fields, becoming a blockchain 3.0 The representative virtual currency of the era, Media Chain 3.0 technology has the core characteristics of being safer, more efficient, more flexible, and more open. The widespread application of its technology will surely trigger new forms and new ideas in the global media industry, which can Create convenient services and new concepts, which marks a new economic era before the public.
Ⅱ Bitcoin has been declared dead more than 100 times, and the king returns every time. It is really based on hype
Is the currency circle really going to be finished?
This question is asked by friends every year
1. It only took 4 months for Bitcoin to rise from US$1 to US$30 in 2011. In June of the same year, due to hacker attacks and other Bitcoin fell 68% in two days due to security concerns.
2. Bitcoin then rose to $266 on April 17, 2013, before falling to $54.25 within a week.
3. When Bitcoin rose to a maximum of $1,156 on November 30, 2013, the regulatory authorities headed by the People’s Bank of China jointly issued the “Notice on Preventing Bitcoin Risks”, clearly stating that Bitcoin is not a currency. , should not be used as currency in the market. Ordinary people have the freedom to participate at their own risk. Financial institutions and payment institutions are not allowed to use Bitcoin to price products or services. It started a violent bear market and fell to the lowest level of $150 in January 2015. During this bear market, the famous Mentougou incident occurred, which I won’t elaborate on here.
4. In 2017, after four years of accumulation, Bitcoin ushered in explosive growth this year, rising to a maximum of 19,821.9 US dollars. After that, the cryptocurrency ushered in a waterfall decline. I believe that many old traders still have fresh memories of 2017. In the following year, the total market value of digital currencies fell by nearly 90%.
5. In the black swan event in the currency circle in March 2019, Bitcoin fell to a minimum of $3,351. After more than a year of correction, a new round of bull market started in March 2020.
Cryptocurrency is now not only played by retail investors, but also many institutions and giant whales are entering the market one after another, and they will not be finished so easily. However, under the current market conditions, it is recommended to trade on regular large exchanges.
Cognition determines wealth, and the depth of cognition determines your future height.
If you don’t recognize digital currency in your heart, don’t dream about getting rich. You will definitely not be able to get rich. First, find a way to recognize the blockchain in your heart and recognize the digital currency you hold.
Bitcoin has been declared dead more than 100 times, and the king returns every time. Is it really based on hype? No, no, absolutely not.
Blockchain is the inevitable result of historical development. Bitcoin is the choice of the times. Bitcoin will not die, and the currency circle will not die.
Nowadays, most digital currencies are linked to Bitcoin. The blockchain, which relies on the underlying technology of Bitcoin, has extended a huge ecosystem around the world.
In the future, people’s hearts will become more and more popular.Consciousness will become stronger and stronger, and the currency circle will accelerate iteration and evolution. Everything has just begun. Golden scales are just things in the pond. They turn into dragons when encountering storms.
Mainstream currencies, especially Bitcoin, are slowly developing in the direction of gold. When do you think gold will end?

Ⅲ What issues did the first China Blockchain Security Summit Forum focus on
June On the 21st, 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 many leaders from national authoritative institutions and the blockchain industry Big names, security industry leaders, many top industry media and overseas authorities participated.
(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.
IV Which exchange is the one where blockchain donations escape?
, Hufu Exchange.
There have been many thefts in this exchange before, the most famous one being that 500 million of the Tiger Talisman Chain was stolen, so it is now being harvested in various ways, extremely vicious, hungry tigers devoured it, especially some time ago The launch of Pangu community’s tokens OSK and FIST has harvested a lot of leeks.
Stay away, stay away.
Pangu Community united with Hufu Exchange to harvest hundreds of millions, OSK plummeted 90%
Hufu Exchange embezzled 30 million users’ assets and is about to run away, please call the police or withdraw cash quickly
2, BIX exchange.
The platform currency plummeted, many times were harvested through contracts, there were rat positions, the founder ran away, the platform suffered multiple thunderstorms, withdrawal restrictions, a large number of funds were vacant, and the risk was extremely high.
3. BIKI Exchange.
Du Jun’s back garden was announced to be liquidated last year, but later it turned out that the overall market situation was still continuing, so he continued to harvest leeks.
The BIKI Exchange in Du Jun’s Leek Manor has harvested countless crops and cannot escape the law
4. ZT Exchange.
5, BKEX exchange.
6. HOBIT Exchange.
Thunder: HOBIT was hacked, data was deleted, the platform currency plummeted, and the service was suspended for maintenance for seven to fourteen days
7. Bit Exchange.
8, ZB Exchange.
9. Matcha Exchange.
IV Who proposed the idea of blockchain
Satoshi Nakamoto (English: Satoshi Nakamoto), who claims to be a Japanese-American, is often translated as Philosophy of Nakamoto by the Japanese media. Man is the creator of the Bitcoin protocol and its associated software Bitcoin-Qt, but his true identity is unknown. Satoshi Nakamoto published a paper titled "Bitcoin: A Peer-to-Peer Electronic Cash System" in 2008, describing a method he called "Bitcoin." "Coin" electronic currency and its algorithm. In 2009, he released the first Bitcoin software and officially launched the Bitcoin financial system. In 2010, he gradually faded away and handed the project over to other members of the Bitcoin community. Satoshi Nakamoto is believed to hold approximately one million Bitcoins.
VI What does blockchain mean
Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system.
1. In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable. and an unforgeable distributed ledger.
2. Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, and uses cryptography to ensure data transmission. and access security, a new distributed infrastructure and computing method that uses smart contracts composed of automated script codes to program and operate data.
(6) Extended reading on the 2010 blockchain event:
1. In 2008, Satoshi Nakamoto first proposed the concept of blockchain The concept, in subsequent years, became a core component of the electronic currency Bitcoin: serving as a public ledger for all transactions.
2. By 2014, "Blockchain 2.0" became a term about a decentralized blockchain database. For this second-generation programmable blockchain, economists believe that its achievement is that “it is a programming language that allows users to write more sophisticated and intelligent protocols. Therefore, when profits reach a certain level, You can earn income from completed shipping orders or dividends from shared certificates."
3. In 2016, the Central Securities Exchange of the Russian Federation (NSD) announced a pilot project based on blockchain technology. Many institutions with regulatory powers in the music industry are beginning to use blockchain technology to establish test models for collecting royalties and managing copyrights worldwide.
4. The timestamp service and existence proof of the blockchain, the time when the first blockchain was generated and the events that were happening at that time are permanently retained.
5. The Bitcoin company BTCC launched a service "Millennium Chain" in 2015, which is the blockchain engraving service, which uses the above principles. Users can engrave text on the blockchain through this service and save it permanently.
Ⅶ [Hall of Fame] Founder of Blockchain Pencil (ChainB) - Prince Baozou Gong
Gong Ming, also known as "Prince Baozou Gong", ICO AGE (formerly China's largest ICO platform) and the founder of Blockchain Pencil (the largest Chinese blockchain media). Since 2012, he has been committed to promoting the development of digital currency and blockchain industries. He has translated and written a large number of relevant materials and blockchain white papers, and participated in "Blockchain Society", "Blockchain - New Economic Blueprint", "Digital Currency" and many other works.
Prince Gong of Baozou·Weibo ID
Speaking of Prince Gong of Baozou, people outside the blockchain circle may be unfamiliar, but This title is extraordinary within the circle.
The first time I met Prince Baozou Gong was at the Gravity Zone event in Chengdu. Many blockchain “believers” came for Baozou Gong that day.
Initially, Prince Baozou Gong was just a Weibo ID.
Initial research on digital currency
Just after he was released from prison in 2010, he plunged into the field of digital currency research. With a salary of 1,200 yuan, he silently predicted The trend of digital currency.
In 2012, the transfer payment method was still very traditional. The cumbersome procedures and extremely inefficient transfer process often made Baozou miserable. “After reading the information on Bitcoin at the time, I felt that this could be solved. My past doubts."
Different from most laymen, Bao Bao, a mathematics major, has not only done program development for more than ten years, but also has experience in finance, so he quickly digested the Bitcoin currency and even the logic of blockchain technology. When he transferred the Bitcoins from his wallet to a friend for the first time, Baozhua was particularly excited. "Transferring money is so convenient. It feels like sending an email for the first time. This is the future!"
Bitcoin has opened the door to a new world, so he is very happy to do some popular science work. "At that time, there were more technical discussions abroad, and I really wanted toThese things spread back home. ”
Translation & Writing
At that time, he translated a large number of foreign materials and reports about Bitcoin on Weibo.
He translated and He has written a large amount of relevant information and blockchain white papers, and participated in many books such as "Blockchain Society", "Blockchain - New Economic Blueprint", "Digital Currency", etc.
Gradually In this country, everyone is accustomed to calling Gong Ming "Prince Baozou Gong", and "Prince Baozou Gong" has become an influential figure in the blockchain circle.
Blockchain Pencil ( ChainB)
Prince Gong translated many articles on blockchain technology, and later created blockchain media: Blockchain Pencil. “I always believe that technology is the most important, so Blockchain Pencil only introduces technology and tells you what is truly valuable. As for the quality of blockchain applications, we will give you various overseas materials for reference. ”
Blockchain Pencil (website domain name ChainB.com) is an authoritative new media that provides the latest and most comprehensive information reports on the global blockchain industry.
Website 7*24 Authoritative, comprehensive and professional blockchain information is published in real time every hour, covering all aspects of blockchain-related industry trends, company news, events and conferences, etc. The content covers blockchain companies, related venture capital opportunities, digital currencies and digital Asset-related developments and other news.
Participate in the EOS super node election
At an event, Prince Baozou Gong mainly introduced the two blockchain projects in which he participated: Decentralized exchange CYBEX and blockchain incubator LongHash.
He said that EOS.CYBEX will develop the first test chain of EOS and provide EOS developers with a complete testing environment and tools for free. Its LongHash incubator can provide free support to outstanding EOS developers around the world. At the same time, taking this opportunity, Baobao officially announced its participation in the EOS super node election.
Why did you choose to be CYBEX and LongHash? Baozou also has its own considerations: “We hope to build a platform that can provide everyone with complete basic services. The biggest starting point for doing these projects is to hope for the healthy development of this industry. ”
With the participation of candidates such as Laomao, Coin Capital, and Gravity Zone, the competition for EOS super nodes is becoming increasingly fierce. Baozou believes in BM’s technical strength, which is why he has been paying attention to the development of BTS. The important reason is that in fact, what CYBEX wants to do on EOS is similar to that of BitShares.
For these reasons, RampageIt is also expected that "CYBEX will bring together its profound development experience, market operation experience and rich industry resources to empower the EOS community."
Ⅷ When did the blockchain explode?
The blockchain exploded on November 28. According to relevant information, the thunderstorm incident was the collapse of South Korea's blockchain star project WEMIX. Within one day on November 28, the WEMIX currency fell by 72.4%. At present, the price of WEMIX coins is only one-fifty of its peak value, and countless players have lost their money. The blockchain world attracts many young people. I joined in with the belief of decentralization, trying to break away from the country's outdated currency system and find a free paradise. What I walked into was a dark jungle society, where reapers lurked in the dark with sickles and sharpened their knives.
Ⅸ Tencent sued Laoganma for owing advertising fees, and in what aspects can blockchain technology work?
We cannot be too superstitious about technology.
I support blockchain technology, but I am not superstitious about blockchain. I do not believe that blockchain is a panacea that can solve various problems.
Having said so much, let me summarize,
First of all, I admit that blockchain technology can play a role in this incident and can also find business opportunities.
Secondly, I hope that both technology providers and project owners will pay attention to blockchain technology and at the same time, avoid being superstitious about blockchain. Don’t think that with blockchain, everything can be solved once and for all.
Thirdly, regarding the Tencent and Laoganma incidents themselves, I suggest that the managers of both parties should check and fill in the gaps from various aspects, strengthen internal risk control, and impose corresponding penalties on those responsible to warn others. , try to reduce the probability of such events. Especially for companies like BAT, as the scale of the company increases, they must pay more attention to internal risk control and prevent big company diseases.
