With the development of encrypted currencies to today, it has ignited the ‘blockchain technology’, and the development of blockchain technology has become the general expectation. In our country, whether it is the giants such as Baidu, Alibaba, Tencent, and JD.com, or ‘new forces’ such as DiDi and OFO, they are all actively exploring blockchain technology. Globally, Walmart, MasterCard,

　　IBM, major car manufacturers, are trying to use blockchain technology to solve industry pain points. In addition, there are enterprises like the Japanese Kodak Company, which is ‘descending day by day’, hoping to fight a ‘turnaround battle’ through blockchain.

　　These phenomena indicate that blockchain technology has great commercial value, and everyone hopes to cultivate a new land in this unknown territory. Therefore, the development of blockchain technology this year has gone beyond being just a basic technology, and has formed a complete ecosystem. Below, we will discuss with you from two aspects: ‘cryptocurrency circle’ and ‘blockchain circle’: how the blockchain ecosystem is, and give you an overview of the blockchain industry.

　　Section 1: Cryptocurrency Circle

　　In the cryptocurrency circle, there are always several terms that cannot be avoided: project parties, exchanges, media, and mining machine manufacturers. Next, let’s delve into what’s going on in detail.

　　1. Project Party

　　The project parties in the cryptocurrency circle can understand it this way: anyone who issues tokens is a project party. Note, it’s the cryptocurrency circle. There are also some project parties that do not issue tokens, such as Alibaba, Tencent, and NetEase, which are also involved in blockchain projects. They do not issue tokens but focus on technology. What about these project parties that do not issue tokens? They mainly focus on the role of blockchain in data security and supply chain management, which we will mention later.

　　再回到币圈项目方这个话题，比如说最近争议比较大的亦来云、之前的波场，这些都是币圈的项目方，还有最近比较热的区块链游戏，在游戏里面赚token这种，他们也属于币圈项目方。

　　币圈项目一个颠覆的地方是，把项目和代币结合在一起，直接用代币代替了股权，而且代币可以直接流通。这一点是一个非常具有革命性的，让很多初始项目，可以更加方便的融资，融资之后，反馈的代币能上lottery and How to find it 交易平台流通，投资方也可以很好的退出。

　　这种“融资-投资”的方式似乎是以另外一种方式，变相实现了股权上市交易流通。

　　所以呢，正是这样一种模式，让币圈项目方成为一个离钱最近的地方，他们很容易圈钱，当然也很容易禁不住诱惑，或者蓄谋已久，圈了钱就跑路。项目方发token的详细流程一般是这样的：

　　第一步是做好一套token系统，这就类似于做一个app应用，这点不是很复杂，因为以太坊都是开源的，类似于安卓苹果系统，开发者可以在上面开发具体的应用；

　　第二步就是写一份白皮书，这就类似于商业计划书，白皮书类似于商业计划书，主要包括项目的团队情况、技术情况等信息；

　　第三步要找人做背书，找一些有影响力的业界大咖来宣传宣传；

　　第四步开始推广营销，找一些区块链媒体推软文，拉合作，这个我们下面会提到；

　　第五步是找融资；

　　第六步上交易所，token开始大范围流传。

　　二、交易所

　　说完项目方，我们来说交易所。如果说项目方是生产者，那么，他们生产出来的东西得去销售、去做交易，对不对？交易所就是项目方token的一个交易场所。如果说项目方的token类似于股票，那么币圈的交易所就类似于股市的二级市场吧。只不过币圈的交易所权力更多一些，有上币审核权，可以决定上币或者下币。

　　当然，项目方想上币，要支付给交易所巨额的上币费用，投资者在交易所里面交易呢，也需要付手续费或提现费，每家交易所手续费提现费规则都不太一样。那其实，上币费、手续费、提现费就构成了币圈交易所的盈利模式，当然，除了这三种盈利模式，交易所的盈利模式还有：“做市商”业务赚取差价，也就是交易所通过不断买卖，创造流动性，充当做市商，同时赚取业务差价。

　　目前，由于行业竞争越来越激烈，上币费和手续费将越来越少，甚至不需要，所以常规盈利所占的比重会越来越少，这就出现了其他的盈利模式，比如说：平台币、杠杆手续费。先来说说平台币。平台币就是交易所发的币：OKB、币安币都属于平台币，交易所发放的这些平台币可以换取BTC、ETH，同时呢，平台币自身价值的增值，可以为交易所的发展奠定坚实的物质基础，对用户而言，持有平台币可以享受到手续费折扣、平台分红、交易所的专项活动等好处，这是平台币。杠杆手续费呢，就是平台上的融币功能，支持杠杆交易，并向融币用户收取一定比例的手续费。

　　上面说的这些其实都是通过交易所自身资源输出而构建的生态系统。现在，交易所还在积极布局全行业来获得收入，比如：成立资本、矿池、钱包、孵化器、工程院、基金等方式。我们认为，如果交易所想长久发展下去，就必须全产业链布局，找到行业的新爆发点，构建完整生态系统，所以，把战略盈利的比重变大。

　　三、区块链媒体

　　在区块链火爆的这两年，不止项目方非常多，媒体也如同雨后春笋一般出现了，目前比较知名的区块链媒体大概有200来家吧。区块链媒体平台上的内容大概就是围绕这么几点：政策、黑客、交易所、大佬、项目方。文字之外，区块链媒体的运营方式还包括社群活动，比如说：邀请“大佬”进群做分享，以这种方式达到优质内容的一个沉淀，同时赚取一些流量。

　　为什么一定要提区块链媒体呢，是因为，区块链媒体和我们印象里面的媒体其实是有些区别的lottery localJoin us。区别在哪里呢？区别就在于：区块链媒体和上面提到的项目方、交易所，这三者之间存在着一些利益关系。我们刚刚说，项目方好比“生产者”，交易所好比“销售市场”，那么，媒体扮演的角色呢，就好比“广告平台”。项目想要卖得好，需要宣传，需要打广告，那么区块链媒体就扮演了这么一个角色，所以，现在一些区块链媒体的投资方正是项目方、交易所。

　　最近这段时间是熊市，多家区块链媒体大规模裁员，究其原因无非是项目短缺，资金不足。所以呢，如果说区块链媒体单纯依靠项目方、交易所的投资、以及广告收入，其实是远远不够的，当熊市来临，项目方、交易所受到波及了，那么媒体势必也将面临非常残酷的寒冬。因此，现在很多区块链媒体也在做项目方发token（最典型的的就是币乎、币车这种内容社区，他们既属于一种媒体平台，又在发token做项目方）、或者有些区块链媒体在做钱包、卖矿机租算力这些业务。

　　However, we believe that blockchain media, as a medium, still plays a guiding role in public opinion. Therefore, it should return to its essence and become a place for the transmission of industry value information, rather than a place for advertising accumulation. Therefore, blockchain media should keep up with technological development to achieve its survival and development. By leveraging the advantages of blockchain technology and the consensus mechanism in the token system, it can achieve a reasonable distribution of interests in the media industry, which may have a certain imaginative space.

　　Four, mining machine manufacturers

　　Bitcoin mining is essentially a competition of computing power. The stronger the computing power, the higher the chance of mining Bitcoin. Therefore, in the entire commercial system of the cryptocurrency circle, mining machine manufacturers are a very important presence. Just look at one data: in the blockchain industry of the Hurun Rich List in 2018, the richest person was Mr. Zhan Kejun, a partner of Bitmain, a mining machine manufacturer. According to the prospectus, Bitmain’s net profit in the first half of the year was $743 million, an increase of nearly 8 times year-on-year. It once occupied more than 70% of the global Bitcoin mining machine market share, becoming the leader of the mining machine industry. Not only mining machines, but also Bitmain still occupies a near-monopoly position in mining pools (a cooperative mining model): currently, the computing power of the top six global mining pools accounts for 79.2% of the market share.

　　And another company that researches mining machine chips, “Canaan Creative”, after inventing China’s first Bitcoin mining machine, began to engage in the research of chips in the fields of blockchain and artificial intelligence. In just a few years, it has become an internationally renowned chip company.

　　In fact, as early as 2012, the United States announced that it would launch a butterfly mining machine, but this matter was later considered a scam by many people, because the butterfly mining machine took several years to be launched, and during these years, it also caused great panic among mining machine research and development in other countries, with everyone racing against time. In a sense, the butterfly mining machine also contributed to the prosperity of the mining machine industry. Therefore, by 2013, the mining machine industry had entered a season of flourishing, with a large number of ASIC mining machines being proposed: announced for research and development, announced for pre-sale, or in the form of inventory, including: the烤猫mining machine, the鸽子mining machine, the TMR mining machine, the比特儿mining machine, the Landre Mining Bureau, the 小蜜蜂mining machine, the 阿瓦隆original factory, and various OEMs, the 花园mining machine, the Smart mining machine, and so on… It is possible that many people have not heard of these mining machines, as most of them have ceased to exist. The remaining Bitmain, Canaan Creative, and Ebang Communication have become giants in the mining machine industry.

　　However, as a derivative industry under the prosperity of the cryptocurrency market, the price of miners is closely related to the market situation of cryptocurrencies: in the bull market, miners are often in short supply, and it is not uncommon for miners to buy miners at several times the price from ‘scalpers’. At this time, miner manufacturers enter the红利 period. However, in the bear market, miner manufacturers will also be affected adversely, as miners’ enthusiasm for mining decreases, and some manufacturers have to reduce the price of miners to recover costs. For example, when Bitcoin plummeted in March this year, a certain model of miner in Huaxingbei was sold at a discount of 5000 yuan, with the price dropping from about 19000 yuan per unit to…

　　14000 yuan.

　　【Summary】

　　Up to this point, we can find that there is a ‘all flourish together, all suffer together’ relationship among project parties, exchanges, media, and miners. In the bull market, project parties can raise funds to issue tokens, exchanges can earn listing fees and transaction fees, and the increase in token value can allow project parties to make more money. Then, they can place advertisements with media, making media earn advertising fees. When the price of tokens is high, miners are enthusiastic, and miners also sell well. However, in the bear market, it is completely…

　　This is a reverse sign, as everyone is facing a winter. Therefore, it is a ‘all flourish together, all suffer together’ relationship.

　　That’s all for the coin circle. Next, let’s introduce the blockchain circle.

　　Section 2: Blockchain Circle

　　The blockchain circle refers to the circle that focuses on blockchain technology. Compared with the coin circle, the blockchain circle seems quite低调. However, without the technical support of the blockchain circle, the coin circle could not exist. Therefore, the blockchain circle is often overlooked, but it is actually very important. The realization of blockchain scenarios in the future will still rely on the technical support of the blockchain circle.

　　Currently, blockchain projects are mainly carried out around the issue of data security in the supply chain. As mentioned at the beginning, companies like Walmart, MasterCard, IBM, and major car manufacturers are trying to use blockchain technology to solve some industry pain points involving data security, such as: the safety of fresh food circulation, vaccine safety, transaction data security, copyright protection, and so on.

　　In terms of the supply chain, the most typical example is the express industry, where SF Express is currently trying to use blockchain technology to solve the issue of drug logistics safety. In addition, Alibaba is actively deploying blockchain in the Xiong’an New Area; Tencent, Baidu, NetEase, and JD.com have developed a number of blockchain-based online games. Although these projects are not very mature at present, they have enriched the business model of blockchain and provided a relatively broad space for imagination.

　　When it comes to the concept of imagination space, for the blockchain circle, it is actually mainly centered around the topic of ‘Blockchain+’: Blockchain+Finance, Blockchain+Insurance, Blockchain+Agriculture, Blockchain+Entertainment, Blockchain+Artificial Intelligence, and so on, covering any industry…In short, it is the realization of blockchain scenarios, turning imagination into reality, just like the popularization of the Internet to every household.

　　【Summary】

　　This underlying technology of blockchain, originally was actually a currency system, serving Bitcoin, but today, this technology has evolved into a way of thinking or method of innovation, and these ideas and methods have indeed become solutions to some pain points in the current Internet era.

　　What are the core technologies included in blockchain?

　　First of all, we can take a look at the official explanation of blockchain technology. In a narrow sense, blockchain is a chain-like data structure that combines data blocks in chronological order and ensures its non-tamperable and non-forged nature through cryptographic methods, which is a distributed ledger.

　　In a broad sense, blockchain technology is a new type of distributed infrastructure and computational paradigm that uses blockchain data structure to verify and store data, distributed node consensus algorithm to generate and update data, cryptographic methods to ensure the security of data transmission and access, and smart contracts composed of automated script code to program and operate data.

　　It may be that everyone knows that blockchain technology is an independent underlying architecture from the Bitcoin system. In terms of architectural model, it is a set of distributed ledger. What is a ledger, naturally, is used for accounting.

　　In blockchain technology, in order to generate accounting records, there must be transactions and movements of funds, so in the early days of blockchain technology, there were corresponding encrypted currencies as circulation items for the mainnet, and the circulation and transaction records of encrypted currencies between various accounts on the mainnet of the blockchain will be recorded on the mainnet.

　　Different from other transaction record databases, the transaction records on the mainnet of blockchain technology are recorded on all the block nodes of the mainnet (that is, all the data blocks), which is what is called the principle of decentralization. That is to say, on the blockchain technology, there is no central database to save all the records, each block on the chain has all the transaction data of the chain, that is to say, each data block is the center.

　　Another characteristic of blockchain technology is its immutability, because every transaction on the blockchain is recorded in all the blocks on the chain, so no single data block can be changed, even if you change it, the other data blocks will also record the real data, and each set of data can be traced back to the time it first appeared.

　　Because of these characteristics of blockchain technology, after the birth of Bitcoin, blockchain has also attracted a lot of attention, and many people have also begun to want to use the technology of blockchain to create a decentralized, traceable, and unchangeable data to ensure the credibility of the data.

　　But blockchain technology also faces many problems, such as single application scenarios, unchangeable original error data, and the irretrievable loss of currency stolen by hackers, etc. What is blockchain technology? What are the core components of blockchain technology?

　　What is blockchain technologyonline casino plan and How to find it? What are the core components of blockchain technology?

　　What is blockchain technology:

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

　　Blockchain (Blockchain) is an important concept of Bitcoin, which is essentially a decentralized database and also the underlying technology of Bitcoin. Blockchain is a series of data blocks generated by cryptographic methods and associated with each other, each containing information about a Bitcoin network transaction, used to verify the validity (anti-counterfeiting) of the information and generate the next block.

　　The core components of blockchain technology:

　　Blockchain mainly solves the trust and security issues of transactions, and therefore it proposes four technological innovations to address this issue:

　　The first one is distributed ledger, which means that transaction accounting is completed by multiple nodes located in different places, and each node records a complete ledger. Therefore, they can all participate in supervising the legality of transactions and can also jointly provide evidence for them.

　　Different from traditional distributed storage, the uniqueness of blockchain’s distributed storage is mainly reflected in two aspects: first, each node of the blockchain stores complete data in a block chain structure, while traditional distributed storage generally divides data into multiple parts according to certain rules for storage. Second, each node’s storage in the blockchain is independent and equal in status, relying on the consensus mechanism to ensure consistency, while traditional distributed storage generally synchronizes data to other backup nodes through a central node.[8]

　　No single node can record the ledger data alone, thus avoiding the possibility of a single accountant being controlled or bribed to keep false accounts. Also, due to the sufficient number of accounting nodes, theoretically, unless all nodes are destroyed, the ledger will not be lost, thus ensuring the security of the ledger data.

　　The second one is asymmetric encryption and authorization technology, where transaction information stored on the blockchain is public, but the account identity information is highly encrypted. It can only be accessed with the authorization of the data owner, thus ensuring the security of the data and the privacy of individuals.

　　The third one is called the consensus mechanism, which is how all accounting nodes reach a consensus to recognize the validity of a record, both a means of recognition and a means of preventing tampering. Blockchain proposes four different consensus mechanisms, suitable for different application scenarios, achieving a balance between efficiency and security.

　　The consensus mechanism of blockchain has the characteristics of ‘majority rules’ and ‘equality for all’, where ‘majority rules’ does not necessarily refer to the number of nodes, but can also be the computing power, share of equity, or other measurable features that computers can compare. ‘Equality for all’ means that when nodes meet the conditions, all nodes have the right to prioritize the proposal of consensus results, be directly recognized by other nodes, and eventually may become the final consensus result.[8]

　　Taking Bitcoin as an example, it adopts the proof of work. Only when more than 51% of the accounting nodes of the entire network are controlled, it is possible to forge a record that does not exist. When the number of nodes joining the blockchain is sufficient, this is basically impossible, thus eliminating the possibility of fraud.

　　The last technical feature is called smart contract, which is based on these credible and unalterable data and can automatically execute some predefined rules and clauses. Taking insurance as an example, if each person’s information (including medical information and information about risk occurrence) is truly credible, it is easy to carry out automated claims in some standardized insurance products.

　　In the daily business of insurance companies, although transactions are not as frequent as in the banking and securities industries, the dependency on credible data is increasing. Therefore, the author believes that the use of blockchain technology, from the perspective of data management, can effectively help insurance companies improve their risk management capabilities. Specifically, it mainly includes the risk management of policyholders and the risk supervision of insurance companies.

　　What is the core layer of blockchain technology?

　　Chongqing Jinvwo Analysis: The consensus mechanism is the core of blockchain technology, and the consensus mechanism largely determines the degree of mutual trust between nodes in the entire blockchain system, as well as the trust level of other users in the data on the blockchain.

　　What is the core of blockchain technology?

　　Chongqing Jinvwo Analysis: The core technologies of blockchain technology are consensus mechanism, joint defense mechanism, and distributed storage.

　　The three core technologies are supported by machine trust, that is, the realization of transaction activities from point to point, decentralization, non-alterable records, non-reversible transactions, and information encryption, etc., through the support of network technology to break through these difficulties.

　　What are the advantages of blockchain technology? What are the classifications of blockchain technology?

　　The development of blockchain technology has become increasingly popular with the continuous expansion of applications. This powerful driving force of development from various industry demands has led to the rapid development of blockchain technology, which has made the achievements of various industries more and more eye-catching. From professional technology to resources, they are constantly concentrated in this industry, thus pushing the development of blockchain technology into a brand new stage, and the influence brought by this development of blockchain technology has also attracted much attention.

　　When talking about blockchain technology, it is inevitable to mention Bitcoin. Many people know that electronic currency Bitcoin does not rely on the issuance of a specific monetary institution, but is produced through a large amount of computation by a specific algorithm. In fact, the core that truly supports Bitcoin is blockchain technology.

　　How does the intangible Bitcoin operate through blockchain technology? The interpretation that is spread in the industry is: the blockchain can be seen as a technical solution for collectively maintaining a reliable database through ‘decentralization’ and ‘detrust’. In simple terms, this technology can be understood as a technology where all participants keep accounts, while in the blockchain technology system, everyone can participate in keeping accounts and jointly determine the authenticity of the records.

　　“Through this technology, even without a neutral third-party institution, mutually distrustful parties can achieve cooperation. In short, blockchain is similar to a ‘machine for creating trust.’” BuBi Company is a leading domestic blockchain service provider, has made many breakthroughs in blockchain technology platforms, can meet the needs of tens of millions of users, and has the ability to quickly build upper-level application business.

　　The blockchain technology adopted by all parties for recording and storing information uses a decentralized distributed structure, saving a lot of intermediary costs and better ensuring data security; at the same time, it has an unchangeable timestamp, which can effectively solve problems such as data tracking and information anti-forgery.

　　Will it become the next风口 in Internet finance?

　　Although blockchain appeared with Bitcoin, the derived value of this technology has exceeded lottery and How to find it. BuBi Blockchain focuses on the innovation of blockchain technology and products, has many core technologies, and has developed its own blockchain service platform. With decentralized trust as the core, it is committed to creating an open value circulation network, allowing digital assets to flow freely. What BuBi wants to do is a new technology and product – to achieve true value circulation, so that the Internet can reach a new height. If this technology is applied, there can be no central institution when transferring assets, and direct asset transfer between us can be realized.

　　In the current international financial market, the central banks of the United States, Swiss banks, as well as some insurance and futures companies, are all competing to develop blockchain technology. Fang Liang introduced that in the Internet finance industry, blockchain technology will first affect payment systems, securities settlement systems, and trading databases as financial infrastructure; subsequently, the technology will also expand to general financial business, such as credit systems and anti-money laundering.

　　“The payment and settlement system in the financial field will evolve towards a decentralized trend, and the electronic ledger supported by blockchain technology is a reliable system that is error-free and tamper-proof, which has a profound impact on payment, settlement, trading, and empowerment.” Li Yan said.

　　Therefore, industry experts believe that blockchain technology may be the next风口 in the Internet finance industry. With the deepening of the interconnection of all things, Yang Tao, assistant director of the Institute of Finance of the Chinese Academy of Social Sciences, also said that blockchain will make it possible for all individuals to become important nodes in the allocation of financial resources, and will also promote the improvement of existing financial system rules, and build a shared and win-win financial development ecosystem.

　　Blockchain technology will affect many industries

　　“Blockchain technology has a wide range of applications in the era of big data.” Li Yan frankly admitted that, in addition to the Internet finance field, blockchain technology has been applied in many fields and shows a promising prospect.

　　For example, the healthcare industry has greatly benefited from blockchain technology. In reality, the leakage of patients’ private information occurs frequently, and the centralized database or filing cabinet management of medical departments is no longer the optimal choice. Medical institutions are using blockchain technology to achieve the confidentiality of patients’ privacy information.

　　In addition, blockchain technology also has great significance in the legal field. Some civil fields often encounter difficulties in proving liability, while blockchain technology can record each step and help judicial authorities identify specific responsible persons.

　　“Especially in the field of assets, whether it is tangible assets such as real estate and cars, or intangible assets such as health and reputation, this technology can be used to complete registration, transactions, and tracking. It can be said that blockchain technology will have its place in any field of production and life that lacks trust.”

　　The development of blockchain technology has also brought about changes in the operation concepts of various industries. The new technology and new concepts have promoted the new development of various industries, and this driving force has a huge impact on society and promotes economic activities. Many new industry phenomena will occur one after another, and the public is looking forward to this new technology being used in various industries to better benefit various industries.

　　What is blockchain technology, what does blockchain technology mean

　　So-called blockchain technology, also known as distributed ledger technology, is a type of internet database technology, characterized by decentralization, openness, and transparency, allowing everyone to participate in the recording of the database.

　　To put it in simple terms: if we assume the database to be a ledger, reading and writing the database can be seen as a bookkeeping action. The principle of blockchain technology is to find the fastest and best person to keep accounts within a certain period of time, have this person keep the accounts, and then send the information of this page of the ledger to all other people in the system. This is also equivalent to changing all the records of the database and sending them to each node on the entire network, so blockchain technology is also called distributed ledger (distributed ledger).

　　What is the core technology of the金窝窝Blockchain technology?

　　The core technologies of the analysis of the blockchain technology by Chongqing Jinvwo are as follows:

　　Distributed ledger technology, asymmetric encryption technology, and smart contracts.

　　What is the core of the金窝窝Blockchain technology?

　　The core of blockchain lies in that it stores all information in independent personal computer networks, making it a decentralized and distributed structure.

　　This means that the system does not belong to any controlling company or individual, but everyone can use and run the system.

　　I specially searched for information to answer you!人人链Blockchain Service allows users to quickly build their own IT infrastructure and blockchain services on an elastic and open cloud platform. Using BaaS can greatly reduce the cost of implementing the underlying blockchain technology, simplify the construction and operation of blockchain, and meet users’ personalized needs in various industry fields with one-stop quick delivery of customized BaaS. Hope it is adopted

　　What is blockchain technology?

　　Blockchain has been hyped to the extreme, but you know nothing about it!

　　Blockchain is a decentralized database system involving the participation of different nodes, which is an open ledger system.

　　It is composed of a series of data blocks or data packets generated by cryptographic methods, that is, blocks (block), and an automatic timestamp is automatically加盖 on each block of data information, thereby calculating a data encryption value, that is, the hash value (hash).

　　In essence, blockchain technology is a distributed accounting technology. It allows everyone to have an instant and synchronized ledger, and every transaction that occurs in the entire network will have thousands of backups and be synchronized recorded. When an evil actor tries to tamper with the ledger data, they must change the ledger in the hands of most people to achieve the goal.

　　What are the three core technologies of blockchain?

　　Introduction to the 7 core technologies of blockchain operation on 2018-01-15

　　1. Blockchain Linking

　　As the name implies, blockchain is a chain composed of individual blocks. Each block is divided into two parts: the block header and the block body (including transaction data). The block header includes the hash (PrevHash) value of the previous block used to implement block linking (also known as the hash value) and the random number (nonce) used to calculate the mining difficulty. The hash value of the previous block is actually the hash value of the previous block header, and the rules for calculating the random number determine which miner can obtain the power to record the block.

　　2. Consensus Mechanism

　　Blockchain was born with Bitcoin and is the basic technical architecture of Bitcoin. Blockchain can be understood as a decentralized accounting system based on the Internet. Systems like Bitcoin, which are decentralized lottery systems, require the consistency of accounting among all honest nodes without a central node, which needs blockchain to complete. Therefore, the core of blockchain technology is the consensus mechanism among individuals who have no trust basis and no central control regarding the legality of transactions.

　　The consensus mechanisms of blockchain currently mainly include four types: PoW, PoS, DPoS, and distributed consensus algorithms.

　　3. Unlocking Scriptlottery local and Latest

　　Scripts are an important technology for implementing automatic verification and execution of contracts on the blockchain. In a strict sense, each output of each transaction does not point to an address, but to a script. A script is similar to a set of rules that constrain how the recipient can spend the locked assets on the output.

　　The legality verification of transactions also depends on scripts. Currently, it depends on two types of scripts: locking scripts and unlocking scripts. The locking script is a condition added to the output transaction, implemented through a script language, and located in the transaction output. The unlocking script corresponds to the locking script, and only by satisfying the conditions required by the locking script can the corresponding assets on this script be spent, located in the transaction input. Many flexible conditions can be expressed through script language. The explanation script runs like a ‘virtual machine’ in our programming field, distributedly running on every node in the blockchain network.

　　4. Transaction Rules

　　Blockchain transactions are the basic units that make up a block and the actual effective content recorded by the blockchain. A blockchain transaction can be a transfer, or it can be other transactions such as the deployment of smart contracts.

　　For Bitcoin, a transaction refers to a payment transfer. Its transaction rules are as follows:

　　1) The input and output of the transaction cannot be empty.

　　2) If the corresponding UTXO output of each input can be found in the current transaction pool, then reject the transaction. Because the current transaction pool is the transaction that has not been recorded in the blockchain, and each input of the transaction should come from confirmed UTXO. If it is found in the current transaction pool, it is a double-spending transaction.

　　3) Each input in the transaction must correspond to an output that is a UTXO.

　　4) Each input unlocking script (unlocking) must be jointly verified with the corresponding output locking script to ensure the compliance of the transaction.

　　5. Transaction priority

　　The priority of blockchain transactions is determined by the blockchain protocol rules. For Bitcoin, the order in which transactions are included in a block is determined by the time the transaction is broadcasted to the network and the size of the transaction amount. As the time the transaction is broadcasted to the network increases, the chain age of the transaction increases, and the priority of the transaction is raised, eventually it will be included in the block. For Ethereum, the priority of transactions also relates to the transaction fee willing to be paid by the transmitter, the higher the transaction fee willing to be paid by the transmitter, the higher the priority of the transaction to be included in the block.

　　6. Merkle proof

　　The original application of Merkle proof is the Bitcoin system (Bitcoin), which was described and created by Satoshi Nakamoto in 2009. The Bitcoin blockchain uses Merkle proof to store transactions in each block, making it impossible to tamper with transactions and easy to verify whether a transaction is included in a specific block.

　　7. RLP

　　RLP (Recursive Length Prefix, recursive length prefix encoding) is a main encoding method for object serialization in Ethereum, which aims to encode the serialization of arbitrary nested binary data. What are the core technologies of blockchain?

　　The core technology composition of blockchain: whether it is a public chain or a consortium chain, at least four modules are required: P2P

　　Network protocols, distributed consistency algorithms (consensus mechanisms), encryption signature algorithms, and account and storage models. These are the core technologies of blockchain, for detailed content, please refer to relevant books on this topic. With the passage of time, what is the core of blockchain economy?

　　Since the birth of Bitcoin, more than 1600 types of online casinos and how to find them have emerged globally, forming a vast industry ecosystem surrounding the generation, storage, and trading of online casinos and how to find them. However, on the whole, the industry is still in its infancy and has a long way to go before reaching the true value application phase.

　　The core of the blockchain economy lies in the reconstruction of business logic and organizational forms, therefore it needs to obtain application examples in multiple industries to demonstrate its value. This article will explore the business model of blockchain applications in various industries from the perspective of combining blockchain with industry needs.

　　Firstly, the core of blockchain is to solve the problem of credit:

　　Credit is the foundation of all commercial activities and finance. The United States has implemented可信 identity recognition since 2011, while China has achieved controllable information dissemination through real-name registration. The significance of blockchain lies in the first time establishing decentralized trust at the technical level, realizing a completely distributed credit system.

　　Secondly, blockchain solves the problem of value exchange:

　　Traditional networks can achieve point-to-point transmission of information, but cannot achieve point-to-point transmission of value. Because information is allowed to be copied, while value must be entitled and unique, it is necessary to rely on a centralized institution to achieve value transfer. Blockchain perfectly solves this problem, providing a method for achieving point-to-point value transfer, where the network implements accounting without relying on any centralized institution. Therefore, blockchain is expected to become the infrastructure for building a new type of finance and the cornerstone of the future value Internet.

　　Blockchain applications

　　Currently, the application of blockchain mainly has two models:

　　1) Native blockchain applications: Directly based on decentralized blockchain technology to achieve value transfer and transaction applications, such as lottery and How to find it;

　　2) ‘Blockchain+’ model: Combine traditional scenarios with blockchain underlying protocols to improve efficiency and reduce costs. It is expected that the application of blockchain in various industries will mainly follow the second model.

　　Blockchain has five core attributes, namely: transaction attribute (value attribute), evidence attribute, trust attribute, intelligent attribute, and traceability attribute. When these core attributes are combined with the needs of the industry, they solve pain points in the industry and become the business model of blockchain applications in various industries.

　　Blockchain + Bank

　　1. Cross-border payment

　　Cross-border payment has long been a pain point in the banking industry. Traditional cross-border payment methods include two main categories: online payment, including electronic account payment and international credit card payment, suitable for retail small amounts; and bank remittance model, suitable for large transactions; both have problems such as long settlement cycle, high costs, and low transaction transparency. Especially in recent years, with the rise of cross-border e-commerce, convenient, quick, secure, and low-cost cross-border payment has become an urgent need in the industry.

　　The role of blockchain:

　　The decentralized and transparent characteristics of blockchain, without the involvement of any third-party payment institutions, shorten the payment cycle, reduce costs, and increase the transparency of transactions. For example, in December 2017, China Merchants Bank, in collaboration with Wing Hang Bank and Wing Hang Shenzhen Branch, successfully realized cross-border RMB remittances among the three parties using blockchain technology. The clearing process is secure, efficient, and fast, significantly enhancing the customer experience.

　　2、供应链金融

　　The pain point of this field lies in the long financing cycle and high costs. With the core enterprise system of the supply chain as the center, third-party credit institutions find it difficult to authenticate the authenticity of various related certificates in the supply chain, causing long manual review time and high financing costs.

　　The role of blockchain:

　　Blockchain introduces characteristics such as consensus mechanism, existence proof, tamper-proof, and traceability into supply chain finance, eliminating the need for third-party credit institutions to authenticate the authenticity of various related certificates in the supply chain, thereby reducing financing costs and shortening the financing cycle. For example, in April 2017, the listed company Yijian Stock and IBM China Research Institute jointly released the blockchain supply chain financial service system ‘Yijian Block’, which mainly promotes the pharmaceutical scenario. To date, more than 30 pharmaceutical distribution enterprises have successfully registered on ‘Yijian Block’, and as of the end of July, the number of transactions has reached nearly 8,000, with a total amount of more than 100 million yuan in funds invested.

　　3. Digital Bills

　　The pain point of the digital bill industry lies in the long-standing problems such as ‘false bills’ and ‘selling the same bill multiple times’, which bring risks to the bill financing business of the banking industry.

　　The role of blockchain:

　　The existence proof and tamper-proof characteristics of blockchain effectively solve the problem of false digital bills; at the same time, blockchain solves the double-spending problem, which can avoid ‘selling the same bill multiple times’. For example, Shenzhen Blockchain Financial Services Co., Ltd. issued ticket chain products, providing bill financing services based on blockchain to meet the financing needs of small and medium-sized enterprises. The cooperative banks include Ganzhou Bank, Guiyang Bank, Suzhou Bank, Shizuishan Bank, Langfang Bank, Wuhai Bank, Jilin Jiutai Rural Commercial Bank, Yaodu Rural Commercial Bank, Shenzhen Rural Industry Bank, Weifang Bank, and Central Plains Bank. In addition, Zhejiang Commercial Bank, JD Finance, HSBC Electronics, HNA, and others are also verifying blockchain digital bill services.

　　1. Asset Securitization

　　The pain point of asset securitization lies in the fact that there are many participants, many operational links, low transaction transparency, information asymmetry, and the authenticity of underlying assets cannot be guaranteed.

　　The role of blockchain:

　　Blockchain introduces attributes such as existence proof, tamper-proof, and consensus mechanism to asset securitization, enabling real-time monitoring of the true status of assets and solving the trust issue of underlying assets among various parties in the transaction chain. Various assets such as equity, bonds, bills, revenue vouchers, warehouse receipts, etc., can be integrated into the blockchain to become on-chain digital assets, improving the efficiency of asset circulation and reducing costs. For example, in May 2017, Baidu Finance, in collaboration with partners such as Baitian Leasing and Huaneng Trust, jointly issued an ABS project supported by blockchain technology with a issuance size of 4.24 billion yuan.

　　Blockchain + Insurance

　　1. Insurance Business

　　The insurance industry is plagued with issues such as information asymmetry and lack of trust between customers and insurance institutions: users find it difficult to choose insurance products suitable for themselves, while insurance institutions face the risk of insurance fraud.

　　The role of blockchain:

　　The decentralized, open, transparent, and traceable characteristics of blockchain create a good communication channel between insurance institutions and users; insurance standard information is centrally managed on the blockchain and is immutable, helping insurance institutions avoid insurance fraud risks; at the same time, smart contracts can improve work efficiency and reduce costs. For example, the French insurance giant AXA is using the Ethereum public blockchain to provide automatic flight delay compensation for aviation passengers. If the flight is delayed for more than 2 hours, the ‘smart contract’ insurance product will automatically compensate the passengers.

　　2, Credit Management

　　The pain points in this field lie in the limited data collection channels of credit institutions, the lack of data sharing, leading to difficulties in accurately representing the credit status of individuals or institutions; in addition, there is also the issue of how to ensure user privacy during the data collection process.

　　The role of blockchain:

　　Blockchain has the characteristics of trustless, consensus, and non-tamperable, which guarantees the implementation of limited and controllable credit data sharing and verification on the technical level, while effectively protecting user privacy. For example, China Ping An’s blockchain credit business has been launched and is in operation. In addition, domestic start-up companies such as Shanghai JuZhen, LinkEye, and BuBi Blockchain are also exploring joint credit reporting and secure evidence storage.

　　As a foundational technology, blockchain has great application value in many industries with distributed processing, point-to-point transactions, and the need for rapid establishment of trust relationships. Its core is to solve the problem of credit and realize the point-to-point transmission of value. Therefore, it is considered to be the cornerstone of the future value internet.

　　The core of the blockchain business model lies in using the innovative attributes introduced by blockchain to combine with traditional industry applications, achieve the reconstruction of business logic, in order to create new application scenarios or improve efficiency and reduce costs.

　　Blockchain will also extend to all fields of social life: Blockchain solves the problems of management, transaction, and transfer of digital assets, and will play an important role in the wave of asset digitization, such as supply chain management, data services, asset management, public services, and the Internet of Things, which are gradually landing in various fields. ‘Blockchain+’ is becoming a reality.

　　The basic information of merchants, product information, transaction information, review information, etc., are stored on the blockchain, with high information authenticity, enhancing the authority of merchants. Although the information on the blockchain is open and transparent, for users, it can be encrypted and verified on the basis of anonymity, which provides more effective protection for users’ personal privacy.

　　Establishing a reward mechanism

　　Users can obtain rewards by inviting others, forming a second-level distribution for merchants, reducing promotional costs while enabling their blockchain platform to quickly expand customer base.

　　Establishing various payment scenarios

　　The blockchain mall supports the transaction of digital assets for all or part of goods, creates digital asset value standards and offline usage scenarios, and solves the problems of financial settlement, cross-border business, and information circulation existing in major e-commerce companies.

　　Establishing low-cost guarantees

　　Guaranteed transactions through the trustworthy smart contracts reduce the trust and transaction costs for both parties in the transaction, and lowers the demand for traditional transaction matching services. At the same time, the decentralized system eliminates the participation of third-party institutions, allowing the two parties to transact directly, shortening the time and improving efficiency.
