Bubi blockchain

1. What is blockchain? Application of blockchain technology

what is a blockchain? In essence, blockchain is a decentralized distributed ledger database, which is the underlying technology of bitcoin, and is associated with bitcoin. The blockchain itself is actually a series of data blocks generated by the use of cryptography, each of which contains the information of effective confirmation of multiple bitcoin network transactions

whenever an encrypted transaction occurs, miners with strong computing power in the network begin to use the algorithm to decrypt and verify the transaction, creating new blocks to record the latest transaction. New blocks are added to the end of the original blockchain in time order, and the account book will keep growing and extending

through the complex setting of public key and private key, the blockchain network will broadcast all the transaction books of the whole financial network in real time, distribute the transaction records to each client in real time, and ensure that everyone can only modify their own property. Of course, there are other people's transaction records in the account book. Although you can see the numerical value and the corresponding transaction address (which is basically composed of a long piece of disordered letters and numbers), you can't know the real identity of the trader without using other technical means

what is a blockchain? Since last year, the concept of blockchain has become popular, especially in some developed countries. Blockchain is also known as subversion, which is very popular all over the world. Blockchain will be the first to impact the financial instry, and then will affect a wider range of economic fields. The prediction is based on several core characteristics of blockchain: decentralization, distributed ledger, point-to-point transmission, tamper proof, etc. Because the birth of blockchain is quite magical, and its development is also concerned with the rise of bitcoin in the world, many people will confuse the relationship between blockchain and bitcoin. Some people think that blockchain is a parent-child relationship with bitcoin, while others think that blockchain was born after bitcoin. But in fact, blockchain is the underlying supporting technology of bitcoin, which can be compared with TCP / IP protocol in the Internet. From a certain point of view, bitcoin can be regarded as the first practical application of blockchain generated simultaneously with blockchain

Application of blockchain technology? Since its establishment, Bubi blockchain has been focusing on the R & D and innovation of blockchain technology and procts. It has a number of core technologies, and has made substantial innovation in many aspects, forming a number of core technological achievements, such as: mathematically proven distributed consensus technology, fast large-scale account book access technology, multi chain general ledger technology supporting business form expansion The interconnection technology between heterogeneous blockchains. On April 25, "gege integral" introced the integral system into the concept of blockchain, opened up by multiple parties, issued and exchanged integral, and promoted the circulation of integral. All cooperative institutions can jointly participate in transaction verification, account book storage and real-time settlement; The third-party payment platform of the enterprise points issuer makes the points in and out more flexible. Bubi has developed its own basic blockchain service platform, which has been applied in equity, supply chain, credit and other fields. Bubi has been committed to building an open value circulation network with the core of decentralized (polycentric) trust, so that digital assets can flow freely

what is a blockchain? Application of blockchain technology? We can use bitcoin to describe several application prospects of blockchain. Bitcoin can be said to be a decentralized currency or asset. Every bitcoin can be traced back and found by everyone at any time. This application prospect means that if the transactions between people can return to the original form of barter from the current monetary value measurement method, then the measure of value is no longer legal currency, but bitcoin or other virtual currencies or virtual assets generated by the blockchain, The benefits of the current sharing economy are just the tip of the iceberg. If this traceability, query and tamper proof feature of bitcoin is applied to credit record system, identity authentication system or property right authentication system, many things like "is this house my property?"“ Whether I am unmarried or married "will not exist at all. According to the current development trend, blockchain will not only reshape all aspects of money market, payment system, financial services and economic form, but also change every field of human life.

2. How to explain the concept of blockchain? The understanding of people in each instry is different, and the relevant explanations are graally emerging because of more and more practical applications. With the popularity of this blockchain technology, the relevant achievements are also growing. If we want to understand this kind of technology, we must have a deep understanding from the reality

in the past six months, the concept of blockchain has graally become hot in China, and the financial circle has been blowing waves of blockchain whirlwind. With its unique technical advantages, blockchain has attracted more and more attention and favor from people in the instry. With the characteristics of decentralization (or multi centralization), high transparency, impossibility of tampering and no single point of failure, blockchain technology is coming into the vision of financial institutions and enterprises. At least it has been applied from theoretical discussion to practical application in many fields, such as digital currency, payment and exchange, registration and settlement, digital assets, traceability and anti-counterfeiting, supply chain, Internet of things, etc

"blockchain" was first released in early 2009 as "bitcoin". Blockchain has become the basic protocol and technical application for the launch, recording and circulation of bitcoin. Although bitcoin has been controversial since it came into being, and it can not even be regarded as "currency" by the government and monetary authorities, the blockchain technology applied by bitcoin has been widely concerned by the government and monetary authorities

why has blockchain become a hot technology and topic

perhaps the most important of these is that bitcoin, which is based on blockchain technology, has opened a new technology and rule system exploration and attempt, which has little connection with traditional society (offline) and is completely applied to the online world (online), such as Internet users' identity verification, wealth confirmation, transaction records, notarization verification, etc, This provides people with an alternative path and unlimited reverie to adapt to the development of the Internet society
from the perspective of its application in bitcoin, blockchain intuitively means a new set of network block (block, also known as community) establishment, bitcoin configuration, netizen identity verification, and bitcoin (value) confirmation and transaction records formed by mining by combining encryption technology with Internet technology, As well as the extended encryption of bitcoin cross block flow (value transfer) (including factors such as block and transaction time identification) registration and verification, the internet protocol rules and ledger system including block chain, whole process encryption and mutual authentication. Because bitcoin is not a substitute for offline fiat money, but a new and decentralized network currency (virtual currency) issued and managed by the illegal monetary authority, which mainly imitates the mode of gold and is completely protected and supported by the Internet basic protocol and strict encryption technology, it has also formed a set of virtual currency which is different from It is also not subject to the new monetary rules and systems of social laws, and can be traded or exchanged with legal tender. Bitcoin has been more than eight years since it was launched, and there has been no record of funds or user information stolen. Its security has been verified, and its efficiency and cost of capital clearing also have obvious advantages. This makes people have more confidence in the blockchain technology applied by bitcoin, and it is also more and more clear that although blockchain is a technology and protocol initiated and applied by bitcoin, blockchain is not the same as bitcoin, and its application will never be limited to bitcoin. The application of blockchain can be decentralized or centralized; It can be public chain mode or private chain mode. Therefore, after bitcoin, blockchain technology is constantly developing and innovating, and constantly exploring new application fields, especially in the financial field

the reason why more and more people attach great importance to blockchain is that with the development and wide application of the Internet, more and more economic exchanges and trading activities have been transferred to the Internet, and the network world (or online society) is rapidly expanding, enriching and active, while online transactions must solve the problems of identity verification, value verification, transaction records, etc The efficiency and security protection of inspection and verification need strict intermediary and agreement (rules or constitution). In this regard, the traditional thinking and practice is to conform to the development track of the transfer from offline trading to online trading, and push the common rules and practices of the real (offline) society to the online (Network) society, but it is increasingly difficult to adapt to the needs of online trading in practice
for example, the natural choice of the party's identity verification is to add the account or transaction password, as well as biometrics such as Facebook, iris, fingerprint, etc., based on the information of the identity documents protected by the laws of various countries, to carry out the identity verification of online transactions. But this method, first of all, makes the citizenship information of the cross-border interconnected network world subject to the real social administrative jurisdiction, At the same time, non digital, multi identity information collection and verification will greatly increase the cost and rece the efficiency
moreover, in real society, all kinds of economic activities involving capital liquidation, except direct cash transactions, require the parties to open accounts in banks and other institutions first, and carry out capital liquidation through the account opening institutions. However, for various reasons, even in a country, it is impossible to require all citizens to open accounts in an account opening institution (including its branches), It is even more impossible to do this between multinational companies, which makes the transactions of the parties who open accounts in different institutions must be completed through the clearing between their account opening institutions. It will seriously affect the efficiency and cost of transaction confirmation and capital clearing if this mode is implemented in the network world

in addition, in real society, the valuation and liquidation of trading activities must involve money, which is legal tender protected by national or regional sovereignty. In the case of cross-border Internet Interconnection and cross-border development of Internet transactions, transaction pricing and capital clearing also involve currency issues. The operation of multiple currencies will greatly increase the cost and risk of clearing. Therefore, the development of network world and network transaction needs the innovation of identity verification, value verification, currency valuation, transaction confirmation and record, account management and verification. Bitcoin and blockchain technology provide very important enlightenment and practice

of course, blockchain is still a new concept and technology, which needs further verification and improvement; The application of bitcoin is also an extreme example: the initial bitcoin can not be directly converted from legal tender, but can only be obtained through "mining" in the network world. Therefore, bitcoin can completely set aside the offline social rules, form a new set of game rules by using blockchain technology, and extend from online to offline. In real society, whether online or offline transactions, the main body is people (including legal persons). The management of their wealth or value should not be completely divided into two worlds, but must be connected and integrated. Therefore, o2o is necessary. This requires the application of blockchain not only to study and solve the problems of the network world, but also to study and solve the connection and integration between the network world and the real society. This will bring more challenges and risks, and also require more people, more strength, more in-depth discussion and innovation. It is also possible that blockchain technology will be replaced by more advanced and perfect technology in the future, but the historical value of blockchain will be indelible

the development of blockchain technology in China

Bubi blockchain is a commercial blockchain. Bubi covers seven areas: exchange, points (multiple points, gege points), insurance (sunshine insurance will launch accident insurance on our blockchain in a month, which can greatly rece channel costs), equity crowdfunding (gold stock chain, etc.), supply chain finance (Qian Xiang, etc.), supply chain (cooperation with the material chain, etc.), jewelry anti-counterfeiting, etc. Some funds cooperating with Bubby have committed 150 million investment funds. Bubby plays the role of "LP" in the fund, helping the fund identify and invest in companies related to blockchain. At present, the average amount of angel investment obtained through Bubi blockchain is about 3 million, with an average valuation of more than 40 million

blockchain can drive the birth of a new business model

the characteristics of blockchain technology enable it to achieve some business models that are difficult to achieve in the centralized mode. For example, in the Internet of things instry, some organizations have proposed to use blockchain technology to manage the identity, payment and maintenance tasks of tens of billions of Internet of things devices. Using blockchain technology, IOT equipment manufacturers can greatly extend the life cycle of procts and rece the cost of IOT maintenance

blockchain technology has a flexible architecture

according to different application scenarios and user needs, blockchain technology can be divided into public chain, private chain and alliance chain, which can be selected according to the actual use of institutions<

blockchain technology is a useful tool to realize sharing finance

the essence of sharing finance is to realize the optimal allocation of financial resources by recing the asymmetry of financial information, and to ensure the implementation of the rights and interests of both parties in the transaction and facilitate the transaction through strict third-party authentication and supervision mechanism. Through the use of blockchain technology, financial information and financial value can be more strictly protected, and more efficient and lower cost flow can be realized, so as to realize the sharing of value and information

"from the perspective of historical development trend, money has always evolved with the development of technological progress and economic activities. From the early physical money, commodity money to the later credit money, it is a natural choice to adapt to the development of human commercial society. As the currency of the previous generation, paper money has low technology content. From the perspective of safety and cost, it is the general trend to be replaced by new technology and new procts. It will take at least 10 years for China to implement digital currency, so digital currency and cash will be in parallel and graally replaced for quite a long time. "“ For digital currency, blockchain technology is an optional technology, which is characterized by distributed bookkeeping, non account based and non tampering. If digital currency focuses on the protection of personal privacy, blockchain technology can be selected. The people's Bank of China has deployed an important force to study and discuss blockchain application technology. However, so far, blockchain still occupies too many resources, whether it is computing resources or storage resources, which can not cope with the current transaction scale. Whether it can be solved in the future depends on the situation. "

the development of Internet is in the ascendant and irreversible. The development of the network world and its connection and integration with the real society are also the general trend, and the corresponding rules and technology are of great significance. China has been in the forefront of the world in Internet application, and should actively explore and contribute to new rule making and technology application, and strive to lead the new development of the Internet world

what is the concept of blockchain? People will realize that blockchain technology plays a more and more important role in reality, and is supported by many organizations, so that the popularization of blockchain in reality has entered a new application stage.

3. First of all, I'd like to introce some well-known blockchain companies in China, and then I'll personally evaluate which one is good. You can judge for yourself

1. Bubi blockchain company, which is engaged in the underlying technical services and instry solutions of blockchain. That is to say, an underlying blockchain is built, and an adaptation layer is built on it, so that enterprises can quickly establish commercial applications. The underlying blockchain is self-developed. The consensus mechanism is pbft, TPS is 5000 transactions per second, UnionPay is 2000 transactions per second, and bitcoin is 7 transactions per second. Of course, different underlying architectures lead to different performance, because Bubi's commercial blockchain pays more attention to performance. At present, Bubi is mainly used in digital assets, supply chain finance, supply chain traceability, public notary and other fields< 2. Bumeng blockchain. Theoretically, bumeng should be regarded as the proct line of Bubi, but Bubi is mainly engaged in the private chain, while bumeng is an alliance chain. So separately, bumeng is Bubi's layout in digital assets. The underlying technology is Bubi blockchain, but it encapsulates the blockchain according to the scene and provides API interface for enterprises. Enterprises issue their own assets on it. According to the characteristics of blockchain, they can freely circulate their assets. At present, some enterprises such as sunshine insurance, Qianxiang finance, crowdsourcing, Haohuo, etc. have joined in, and the assets in them include insurance policies, integral points, and so on Financial procts and so on. Finally, it is estimated that this platform will break through the barriers between assets, and the end users can freely use and transfer these assets. This is an interesting way for the blockchain instry, because it has both the opening of public chain and the security of private chain

Third, only chain, which is a commodity ID management cloud platform based on blockchain technology, provides enterprise users with commodity asset management, tracing, anti-counterfeiting verification, new supply chain management, etc. in the form of baas. Simple understanding is that only chain has done the content of "supply chain traceability" of Bubi blockchain

four, concentric mutual aid, concentric mutual aid is a mutual aid security platform, put some mutual insurance related information into the blockchain, and users can apply to become nodes, participate in bookkeeping, and maintain their own data

5. Xiaoyi is a decentralized network protocol based on blockchain technology, which digitizes the assets and interests of the real world, and carries out financial business such as registration and issuance, transfer transaction, clearing and delivery through point-to-point network

these five blockchain companies are probably well-known in China, and I personally recommend bumeng

first, bumeng uses the underlying technology of Bubi blockchain, which is very promising in the instry. It has the largest number of landing applications in China. Enterprises can not only use the blockchain technology at low cost (just call the interface, it seems that it is free), but also use the resources inside. Think about being on the same chain with many enterprises and docking resources in the future, User transformation should not be easy

Second, Weilian and Tongxin Huzhu focus on one field, and do not provide underlying technology and instry solutions. That is to say, if you are in this instry or can be used in the upstream and downstream of this instry, you can not be used in other fields. Take mutual security field as an example, zhongtuobang and zebra Club both choose bumeng. Of course, if it is an investment, you can consider it

Third, Xiaoyi, why not recommend Xiaoyi, because Xiaoyi is an open source project, and we all know the domestic business environment, especially when the instry is just beginning to develop, and the domestic market is different from that of foreign countries, Xiaoyi has gone through two rounds of ICO, which will be a great worry in the future operation, and at present, Xiaoyi has not been applied in practice, We have made a Fada platform, which has not been used by any company yet (guess it may be related to the factors of open source, who dares to open their data completely). Of course, the open attitude of Xiaoyi is worth encouraging. Although I guess the advantages and disadvantages of the code are well understood by peers, it is not clear

Fourth, why is there no recommendation for Bubby? Bubby has raised 30 million yuan a while ago, because Bubby is more open and has more resources. Of course, if the business requires high privacy, it can also choose Bubby blockchain

finally, for all my hard work, choose me!

5. As a rookie of Bubi blockchain, I'll tell you
Application of blockchain technology in banking

2.1 self regulatory platform

we rarely see a platform that can conct self-regulation without intervention. In all areas similar to the financial instry, central banks and regulators (such as the securities and Exchange Commission) come to set uniform rules and manage them. Blockchain technology makes the system no longer need the supervision from enterprises or government entities, so as to regulate the operation of the system. Blockchain provides a mechanism called "workload proof", which allows each computer node in the system to participate in the approval of each transaction. The system has built-in check and balance mechanism to ensure that no computer in the system can deceive the system. All of these reviews and supervisions are completely automated by the computer. At present, there are many other consensus models that can replace the "workload proof" mechanism, but still retain the core idea that each client or node can manage the system point-to-point. What's more, blockchain makes every element in the system completely transparent. Therefore, for such a large-scale community all over the world, blockchain technology can easily review and manage it - "supervision from the public", thus effectively recing fraud. Imagine how much it can save costs and improve efficiency

2.2 compliance with the law and easy tracking

actors (users) and their behaviors (sending money or assets to others) are recorded on the blockchain. Any transaction between the two parties can be tracked and inquired, and can be proved in court. This is because all transactions need a set of public key / private key to encrypt and decrypt processing and transactions. Once they are added to the blockchain, they are permanent and unchangeable. Any record, once written to the blockchain, cannot be tampered with. Anyone holding assets or digital currency on the blockchain will have their own public key on the blockchain. When a transaction occurs, it needs to be signed by the previous holder who controls these assets using the private key. Blockchain also allows a variety of mechanisms for transactions. For example, it can be set to require two people to jointly sign a transaction. In a system without endorsement of enterprises or government, the legally binding mechanism can greatly enhance the trust factor for the system

2.3 built in business continuity

a global platform can not bear the risk of downtime when concting major transactions. Blockchain, a complete point-to-point network, has many distributed nodes and computer servers to support, which has high reliability. Every node in the system keeps a of the complete blockchain data. This makes the whole network highly fault-tolerant, if any part of a few nodes have problems, it will not affect the other parts of the network continue to operate. This makes it possible to achieve 24 / 7 all-weather operation characteristics like disaster recovery center or database rendancy center without using complex technology

2.4 evolution model without burden

in the system, there are a series of rules and key points to help decide who has the right to approve the transaction and what needs to be reviewed before the transaction is written into the blockchain. Blockchain technology can fork out new versions according to different environments and business model requirements. The new version also needs to conform to the overall concept of blockchain. All these changes must be approved by all members of the system, and everyone can get the same benefits. In addition, these changes will not affect the transactions that have occurred and confirmed on the blockchain. For a system, it has enough robustness and flexibility. People often compare the similarities between the Internet and blockchain, including their growth potential and business prospects. These two systems have very similar characteristics. The Internet does not need or does not have a centralized management department (except for a few for the management of agreed URL and domain name registration), but also has enough rendancy and strong fault tolerance. The Internet has been developing for so many years, from basic text to rich graphics, video, animation, and all this has not affected other existing systems and content. Blockchain has fully proved its function and practicability in bitcoin system. Just as the famous Chinese philosopher Lao Tzu said, "the tree that embraces is born at the end of a tree."; The platform of nine layers starts from the base soil; A journey of a thousand miles begins with a single step. " I think this should be the creed of all the pioneers of blockchain technology
as a rookie of Bubi blockchain, I tell you so much!

6. A special database technology, which is based on elliptic curve digital signature algorithm in cryptography to achieve decentralized P2P system design. But the role of blockchain is not limited to bitcoin. Now, when people use the word "blockchain", sometimes it refers to data structure, sometimes it refers to database, sometimes it refers to database technology, but no matter what the meaning is, it has no inevitable connection with bitcoin

from the perspective of data: blockchain is a kind of distributed database. The "distributed" here is not only reflected in the distributed storage of data, but also reflected in the distributed records of data (that is, it is collectively maintained by system participants). In short, blockchain can realize distributed recording of global data information (which can be collectively recorded by system participants rather than centralized recording by a centralized organization) and distributed storage (which can be stored in all nodes participating in recording data rather than centralized storage in centralized organization nodes)

from the perspective of effect: blockchain can generate a set of time sequence, tamper proof and trustworthy database, which is decentralized storage and data security can be effectively guaranteed<

the working principle of blockchain technology

today's blockchain technology can be summarized as a technology to collectively maintain a reliable database through centralization and de trust in the past. In fact, blockchain technology is not a single and brand-new technology, but the result of the integration of a variety of existing technologies (such as encryption algorithm, P2P file transfer, etc.), which are cleverly combined with the database to form a new way of data recording, transmission, storage and presentation. In short, blockchain technology is a technology that everyone participates in recording and storing information. In the past, people entrusted the work of data recording and storage to the centralized organization, while the blockchain technology allows everyone in the system to participate in the data recording and storage. Under the distributed peer-to-peer network without central control point, blockchain technology uses the method of distributed collective operation to build a P2P self-organizing network. Through the complex verification mechanism, the blockchain database can maintain the integrity, continuity and consistency. Even if some participants commit fraud, the integrity of the blockchain cannot be changed, let alone tamper with the data in the blockchain

the source of blockchain technology principle can be summarized as a mathematical problem: Byzantine general problem. Byzantine general problem extends to Internet life, and its connotation can be summarized as: under the background of Internet, when we need to exchange value with unfamiliar opponents, how can we prevent people from being deceived and confused by malicious saboteurs, so as to make wrong decisions. The Byzantine general problem is further extended to the technical field. Its connotation can be summarized as: in the absence of trusted central nodes and trusted channels, how to reach a consensus among the nodes in the network. Blockchain technology solves the well-known Byzantine Generals Problem - it provides a way to create consensus networks without having to trust a single node<

Application of blockchain technology

blockchain technology overlaps three fields:
1, currency: issuance mechanism, distribution mechanism, adjustment mechanism
2, contract: equity, mutual insurance, right registration and transfer, smart contract, etc.
3, Governance: identity authentication, health management, notarization, judicial arbitration, decentralized autonomous organization, Voting, etc.

blockchain is like a "trust creating machine". What Bubi blockchain needs to do is a new technology and proct to realize real value circulation and make the Internet reach a new height

when it comes to blockchain technology, we have to mention bitcoin. Many people know that electronic currency bitcoin is not issued by a specific monetary institution, but generated by a large number of calculations of a specific algorithm. In fact, the core of real support for bitcoin is blockchain technology

How can invisible and intangible bitcoin operate through blockchain technology? The popular interpretation in the instry is that blockchain can be seen as a technical solution to collectively maintain reliable databases through "decentralization" and "distrust". Generally speaking, this technology can be understood as the technology of all participants in bookkeeping. In the past, people used a centralized server for bookkeeping. In the blockchain technology system, everyone can participate in bookkeeping and jointly identify the authenticity of records

"through this technology, even if there is no neutral third-party organization, the two sides who do not trust each other can cooperate. In short, blockchain is like a "trust creating machine."“ Blockchain technology is widely used in the era of big data. " At present, in addition to the field of Internet finance, blockchain technology has been applied in many fields and has shown great prospects

in addition, blockchain technology is also of great significance in law. Especially in the field of assets, whether it is physical assets such as real estate and automobile, or intangible assets such as health and reputation, we can use this technology to complete registration, transaction and tracking. It can be said that blockchain technology will be useful in any field of proction and life that lacks trust. "

blockchain technology concept stocks

it is recommended to pay attention to it manufacturers with blockchain technology and applications. We think that blockchain is more like a mechanism or technical solution. In the future, manufacturers who can combine this mechanism into different scenarios for promotion and application are expected to achieve subversive success. Blockchain technology can ensure that the data structure will not be tampered and forged, and has broad application prospects in the field of financial payment. Bubi blockchain has set up a special team around digital currency, focusing on the development trend of digital currency for a long time, and has set up a special team to carry out relevant work around the instry development demand of digital currency, including the research on blockchain technology.

7. What can blockchain do? Blockchain, a great technology with the birth of bitcoin, can greatly rece transaction costs and improve efficiency in the financial field, which is enough to make Wall Street excited. However, this is only the tip of the iceberg, and its potential application prospects are very wide, which will subvert all aspects of our lives in the future. Internet is an information network with 0 and 1 flowing in it. Blockchain is a value network, which plays a role in value transmission, which is different from Internet in data transmission. When it comes to value transfer, there is a very simple scenario, such as payment. I have 100 yuan in hand. I want to transfer to the group by wechat red envelope or wechat transfer. In this transaction process, a third party is required to participate, while the transmission mode of blockchain is point-to-point transmission, without any intermediate node, This is a big difference between blockchain and our existing architecture. When it comes to point-to-point payment, many people think of bitcoin, because most people know about blockchain from bitcoin. What's the difference between blockchain and bitcoin? Blockchain is the technology behind bitcoin; Blockchain is a basic technical architecture. Through a specific data structure and consensus algorithm, an autonomous system with multi-party participation is designed and implemented. A specific data structure is actually the name of the blockchain itself, that is, its data is put in a block of data blocks, and then the data blocks are connected and implemented by a chain“ "Consensus algorithm" is a very important concept in blockchain. Without synchronic algorithm, there will be no blockchain. Introction to Bubi blockchain since its establishment, Bubi blockchain has been focusing on the R & D and innovation of blockchain technology and procts. It has a number of core technologies, and has made substantial innovation in many aspects, forming a number of core technology achievements, such as: mathematically proven distributed consensus technology, fast large-scale ledger access technology Multi Chain general ledger technology supporting business form expansion, interconnection technology between heterogeneous blockchains, etc. On April 25, "gege integral" introced the integral system into the concept of blockchain, opened up by multiple parties, issued and exchanged integral, and promoted the circulation of integral. All cooperative institutions can jointly participate in transaction verification, account book storage and real-time settlement; The third-party payment platform of the enterprise points issuer makes the points in and out more flexible. Bubi has developed its own basic blockchain service platform, which has been applied in equity, supply chain, credit and other fields. Bubi has been committed to building an open value circulation network with the core of decentralized (polycentric) trust, so that digital assets can flow freely. So far, let's analyze the difference between blockchain and bitcoin? 1. Essential difference. For the world, bitcoin is a digital currency based on cryptography, while blockchain, as we have just said, is a protocol of value transmission. There is an essential difference between the two, because one is digital currency and the other is a protocol of value transmission. 2. Algorithm. The consensus algorithm of bitcoin is based on a work algorithm called workload proof, pow. There are many different consensus algorithms in blockchain, including bitcoin POW algorithm, POS algorithm and DPS algorithm. 3. Transaction speed. Bitcoin has a maximum of seven transactions per second. Please note that we are talking about the maximum rather than the average, because this is a very strict definition. For blockchain, the number of transactions per second can reach tens of thousands or so, so this is also a major difference between blockchain and bitcoin. Because many people will confuse that the transaction speed of blockchain is seven transactions per second, which is wrong. This is a limitation of bitcoin. Blockchain can achieve very high transaction speed according to its different consensus algorithms and linking methods. 4. Link form. Bitcoin is a blockchain based on the Internet, that is to say, we call it public chain. Blockchain can be in the form of public chain, private chain or alliance chain. 5. Limitations. It is suggested that you do not touch some digital currencies related to blockchain. What is the reason? Bitcoin, as a digital currency, although it has very different characteristics, it does not comply with financial regulation. In other words, the 21 million bitcoins were issued without national authorization and national credit as a multiple. Blockchain also has some limitations. Although it is only a protocol and a technology, it is still a new technology in its infancy. To sum up, blockchain is a relatively low-level protocol and a technical infrastructure, on which there are various consensus algorithms. If the blockchain is 1, the consensus algorithm may be 10 to 20, but there may be 1000 or 2000 applications on it. In other words, bitcoin is only one implementation of many blockchain applications. Therefore, bitcoin and blockchain are not equal. Bitcoin is only a very primary implementation of blockchain. What can blockchain do? What about blockchain? In the bill market, the digital bill based on blockchain technology can become a safer, more intelligent and more convenient bill form. The point-to-point transaction with the help of blockchain can break the existing function of bill intermediary and realize the disintermediation of bill value transmission; The construction and data storage of the digital bill system do not need the central server, which saves the development cost of the central application and access system, reces the maintenance and optimization cost of the system under the traditional mode, and reces the risk of the system centralization; Based on the non tamperability of information in the blockchain, once the bill transaction is completed, there will be no default phenomenon, so as to avoid the behavior of "selling more than one vote" and asynchronous payment and endorsement, and effectively prevent the bill market risk. The securities exchange market is also a promising field of blockchain technology. At present, the traditional securities trading mode has the disadvantages of long trading process, low trading efficiency and high comprehensive cost, and there are strong intermediaries and regulatory agencies, so the rights of financial consumers are often not guaranteed. With the application of blockchain technology, buyers and sellers can directly pair through smart contracts, and the efficiency of transaction execution can be greatly improved. Through the distributed digital registration system, settlement and delivery can be automatically realized. Because the data entered into the block is irreversible and can be copied to each data block in a short time, the information entered into the block chain actually has the effect of publicity, so the occurrence of transactions and the confirmation of ownership will not be controversial. What can blockchain do? What about blockchain? Although at present, there is no mature underlying blockchain technology platform solution, technical problems such as capacity scalability, privacy protection, non net settlement and non recourse need to be solved, and large-scale application of blockchain technology also needs to reset it architecture and reengineer business process, these are only technical problems. The real test of blockchain technology rooted and growing in the financial field is the regulatory agencies and financial institutions. Will the inherent "de supervision" and "de centralization" characteristics of blockchain make the market players have no power to drive technological innovation.
