Comparison of blockchain open source

1.
In the past, when it comes to blockchain, we always think of foreign procts, such as Ethereum. But when I talk about this topic today, I think more about China's own blockchain technology
at present, the mature application of blockchain technology is more concentrated in some public chain projects, because many application projects need to be developed based on this, so I think the current global landing direction is public chain projects, and it is still too early to talk about maturity. After all, bitcoin and Ethereum are still blocked, and many old problems have not been solved, There will be many new problems. The well-known ones are Biyuan chain, ulord (the project is abroad, but the technical party provides it in the domestic company, Hunan Tianhe Guoyun Co., Ltd.), quantum chain, Xiaoyi Neo, gongxinbao, etc
ulord is a point-to-point value delivery public chain. By building the underlying architecture of blockchain and digital resource distribution protocol, it supports third-party developers to build their own applications on top of their open source protocol, and works with many instry partners to build a complete ecosystem of blockchain technology and applications
based on various rules and protocols created by ulord, it is convenient to graft various digital resource application scenarios including text, pictures, music, video, software, etc., providing a direct docking platform for information creators and consumers. Third party developers can build their own economic system in ulord, or focus on building all kinds of applications around ulord, and use the ulordtoken in ulord as the voucher in the system
for example, an experience sharing platform can be built on ulord, where the experience sharers price the published experience, and the people who obtain the experience information trade on the platform, and each fee paid to the experience sharers will arrive at the account immediately; Proct promoters can publish ads on ulord, price ads, and people who are interested in ads can get certain profits by clicking on ads. The first mock exam is to separate information from the past, and to use platform or other centralized organizations to spread profit. This mode eliminates intermediate links, and information providers and consumers directly connect with Ulord, which ensures the maximization of the interests of the originator. p>
2. 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!

3. Blockchain is the biggest trend in the next decade
if you look at the problem with the thinking of 30 years ago, you will think that others are crazy, but in fact you are out of date
the concept of blockchain can be traced back to the end of 2008. In the forum, a mysterious personage named "Nakamoto Tsung" published a paper "bitcoin: a peer-to-peer e-cash system" and proposed the concept of blockchain for the first time
on January 3, 2009, the first block of the blockchain was born, which is called the "Founding block"
almost with the birth of blockchain technology, bitcoin became the first thing to play its role. In the following years, bitcoin graally swept the world. In 2017, its crazy market made blockchain technology known to all
the idea of blockchain first appeared in the famous bitcoin open source project. In the process of its birth and development, bitcoin project draws on the technical achievements from digital currency, cryptography, game theory, distributed system, cybernetics and other fields. It can be said that bitcoin project is good at all. As its core supporting structure, blockchain technology is a remarkable innovation achievement
blockchain is a distributed database system with different nodes, which is an open ledger system<
three characteristics of blockchain
compared with the traditional centralized scheme, blockchain technology mainly has the following three characteristics:
the core idea of blockchain is decentralization
in the blockchain system, the rights and obligations between any node are equal, and all nodes have the ability to vote with computing power, Thus, the result recognized by more than half of the nodes is guaranteed. Even under serious hacker attacks, as long as the number of nodes controlled by hackers does not exceed half of the total number of nodes in the world, the system can still operate normally and the data will not be tampered with
block chain's biggest subversive is the establishment of credit
the collective maintenance of blockchain can rece the cost
in the centralized network system, the maintenance and operation of the system depend on the operation and operation of platforms such as data center, and the cost cannot be omitted. Anyone can participate in the nodes of the blockchain. Each node can verify the correctness of the results of other nodes' records while participating in the records, which improves the maintenance efficiency and reces the cost
in a word, blockchain touches money, trust and power, which are the fundamental basis for human survival< Its development has gone through three stages
1. Brewing period: from 2009 to 2012, bitcoin and its instrial ecology are the main economic forms
2. Embryonic period: from 2012 to 2015, with bitcoin entering the public view, new wallet payment and remittance companies appeared, and blockchain economy spread to the financial field. The underlying technology of blockchain is constantly innovated. Blockchain technology is separated from bitcoin system
3. Development period: in 2016, we began to explore instry applications, and a large number of blockchain start-ups appeared. The popularity of ICO in 2017 has given blockchain unprecedented attention
"blockchain 2.0 era" is coming
the application service layer is the driving force for the sustainable development of blockchain, which is divided into three stages of application: 1.0, 2.0 and 3.0
programmable currency: blockchain 1.0 application
programmable currency is the digital currency represented by bitcoin, but it is not the legal tender of any country or region, and there is no government authority to provide guarantee for it
programmable Finance: blockchain 2.0 application& quot; Smart contract& quot; Using program algorithm to replace the concept of contract execution. This enables blockchain to expand from the original monetary system to the registration and transfer of equity, creditor's rights and property rights, the transaction and execution of securities and financial contracts, and even the financial fields of gambling and anti-counterfeiting
programmable Society: blockchain 3.0 application
blockchain is the core of value Internet, which can confirm, measure and store the property rights of information and bytes representing value in each Internet. It can not only record the transactions of the financial instry, but also record almost anything valuable that can be expressed in the form of code. Its application can be extended to any field with demand, and then to the whole society
at present, the application of blockchain has begun to surpass bitcoin (blockchain 1.0), enter the era of blockchain 1.5, and transition to the financial field (blockchain 2.0)
in the next 3-5 years, blockchain may go beyond the financial field and enter the field of social notarization and intelligence (blockchain 3.0), including identity authentication, notarization, arbitration, audit, domain name, logistics, medical care, mail, visa, voting and other fields. Its application scope will be expanded to the whole society, and blockchain technology is likely to become a new technology& quot; All things are connected& quot; It's the lowest level protocol
at present, blockchain technology has been recognized by the world, and its development has become an inevitable trend. Accompanied by more people's attention, "in the next 30 years, new technologies will be integrated into all aspects of traditional instries, and human society will turn upside down. No matter who you are, no matter where you are, all of us will be a part of this great change."
this is the current situation. Blockchain has given the post-90s an opportunity. However, if you want to control blockchain technology without being affected by negative factors, the most important thing is to have a clear understanding of it, whether it is regulators, researchers, speculators or bystanders
it's time to devote more energy to blockchain technology
in China, the average annual salary of blockchain positions has reached more than 300000, and that of some enterprises has reached more than 1 million. The monthly salary of blockchain instry graates in Beijing, Shanghai and other places has exceeded 20K! If the post-90s seize the bonus of the times, they may become the next Alibaba in the future! If you miss it, you may regret it for ten years.

4. Part of the code is open source, the core code is not open source
or when it is open source, there is a bug in 10 lines
the development of likelib public chain has the following stages: condensation stage, solid foundation (in the next 1-2 years), improvement of technical design documents, completion of basic mole code development, online main chain, continuous improvement of intelligent contract, multi chain parallel, cross chain consensus and other early functions, improvement of main chain, side face and surrounding ecology, including blockchain browser, light wallet and mobile wallet, Smart contract, virtual machine, compiler, development tools, multi language adaptation, etc. Establish, develop and improve open source community, start and promote more application access
in the integration stage, it will grow steadily (in the next 3-5 years), complete the implantation of more consensus moles, realize the self evolution of network, storage and other moles (support EB level data storage), form a standard technical solution system for docking applications in various instries, and explore a new ecosystem combining blockchain with big data, artificial intelligence and other fields. Form a mature open source community and establish application side chain on a large scale
in the sublimation stage, a technology platform integrating blockchain, big data and artificial intelligence will be established everywhere (in the next five years) to provide comprehensive solutions for the proction and operation needs of instry, agriculture and commerce. Form an open source community with the integration of blockchain, big data and artificial intelligence, and provide a comprehensive value docking and cooperation platform.

5. I just want to say what I know better. One is an open source project based on bitcoin system, called cravecoin, and the other is Ethereum. At the beginning, we chose cravecoin for source code analysis, and wanted to carry out secondary development on top of it. However, because Ethereum is more open and well supports smart contracts, we gave up after analyzing for a while
after entering the research of Ethereum, I wanted to start from the underlying source code at the beginning, but the whole process was rather difficult. After re analyzing our requirements, I felt that we could develop to some extent and meet some needs by using its existing interface, so I translated the comments of the source code, basically understood the role of each mole, and no further modification was needed, After all, Ethereum is also a project that took dozens of big bulls a long time to build.
it is very difficult for us to successfully transform it into what we want in a period of time. The faster, the easier, the better
and there is a very important problem. If Ethereum is changed, it will not be able to connect to its public network and use the second largest amount of computing power in the world. This is a matter of putting the cart before the horse. It seems that the answer is wrong, but the main expression is that if the subject wants to do development, it is enough to carefully analyze a project,
after all, the logic is almost the same. We should learn more about blockchain and pay attention to ATV

6. 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
blockchain is an important concept of bitcoin. In essence, it is a decentralized database, as well as the underlying technology of bitcoin. One of the most basic characteristics of bitcoin is decentralization. In recent months, financial giants have graally begun to pay attention to the technology of bitcoin, and used it in non monetary fields, such as trading, voting and so on 1) Art instry
artists can use blockchain technology to declare ownership, issue works that can be numbered and limited edition, and can target any type of art in digital form. It even includes a trading market where artists can buy and sell through their websites without any intermediary services
(2) the real estate instry
uses blockchain technology to solve various problems faced by everyone when participating in real estate, including naming process, land registration, agency and so on
(3) the insurance instry
the financial instry has always been the most sensitive to advanced technology. Traditional banking and securities giants have been investing in blockchain venture capital since 2014, with a total global investment of US $1 billion in two years
(4) P2P wallet
personal assets can be traded through this P2P wallet in the future without going through any central organization, such as bitcoin
most blockchains are in their infancy, and most of them are overseas. There are very few good blockchain projects in China, so it is not recommended that any non professionals invest in blockchain projects. If you are very interested in blockchain technology and have technical or financial background, it is suggested to consider starting a business in this area. In terms of protocol system of blockchain, the bottom layer is the underlying technology of blockchain, including the technical protocol of blockchain, as well as some platform routing and basic algorithms; In the middle layer, we need to solve the problems of some application interfaces and the issuance and verification of some certificates, including the services of some instry platforms, big data analysis, etc. This is a rough division, and there should be more detailed division; The top is some applications of blockchain, including financial applications and other applications, Internet of things and so on
Introction to Bubi blockchain
since its establishment, Bubi blockchain has been focusing on the R & D and innovation of blockchain technology and procts, has a number of core technologies, and has made substantial innovation in many aspects, forming a number of core technology achievements, such as: mathematically verifiable distributed consensus technology, fast large-scale ledger access technology, and so on 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
the simple understanding of blockchain is a technology at the bottom of bitcoin, which is also a point-to-point e-cash system, which can realize point-to-point value express. We should distinguish the concepts of bitcoin, bitcoin blockchain, blockchain and blockchain technology. In the countries with more developed finance in the past, the technology of Finance and block has a long history, and the legislation of digital currency and block chain network is also very important. With the advent of the financial era, large financial institutions are studying blockchain technology. They have their own team and concept technology. Graally, regional banks are also participating in the discussion of digital currency. In addition to the application and support of this technology, blockchain has great influence on enterprises. For larger domestic enterprises, Bubi block is also applied to all kinds of equity In the fields of supply chain and points, domestic financial institutions and enterprises have focused on the value of new instries and developed their own blockchain platforms. Blockchain has instantly become a new domestic innovation instry. Overseas, compared with China, the United States has already obtained 15 blockchain patents at the end of last year. The application of blockchain finance is entering a new stage in an all-round way. Various applications will be more and more in-depth, and the relevant changes will attract more and more attention, which will also form a great new trend
financial institutions have launched blockchain technology into a new era of Internet and big data applications, which has laid a pattern from negative interest rate profit driven innovation to technological innovation. At this time, domestic giants have suggested that the cooperation alliance not only affects the implementation of financial infrastructure, but also is an important means to expand business cooperation. In terms of implementation, the future payment system securities deposit will not only affect the implementation of financial infrastructure, It is inseparable from the financial and settlement system and big data analysis, while the domestic giants join hands and propose a mutually beneficial cooperation mode, which can not only effectively improve operational efficiency, but also rece costs and find new growth points, After the adoption of blockchain technology, whether the company's procts and services can proce a new business model or a cost advantage far lower than that of competitors
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. However, because the blockchain is a technology based on mathematical algorithm, the establishment of trust relationship between all parties does not need the help of intermediaries or authority centers, and the cost of establishing trust relationship is almost zero (on the premise of the establishment of blockchain financial infrastructure and ancillary infrastructure), and the blockchain code is open-source, no geographical restrictions, and the network pattern is distributed and interconnected, It lays a technical foundation for the establishment and development of Inclusive Finance and shared finance in the future, and creates material conditions for the integration and unification of global finance. From this point of view alone, blockchain technology is bound to establish a core position in the future financial development, and rely on and complement each other with finance, and win-win in the future.
blockchain is an important concept of bitcoin. In essence, it is a decentralized database, as well as the underlying technology of bitcoin. One of the most basic characteristics of bitcoin is decentralization.

uses blockchain technology to solve various problems faced by everyone when participating in real estate, including naming process, land registration, agency and so on
(3) the insurance instry
the financial instry has always been the most sensitive to advanced technology. Traditional banking and securities giants have been investing in blockchain venture capital since 2014, with a total global investment of US $1 billion in two years
(4) P2P wallet
personal assets can be traded through this P2P wallet in the future without going through any central organization, such as bitcoin
most blockchains are in their infancy, and most of them are overseas. There are very few good blockchain projects in China, so it is not recommended that any non professionals invest in blockchain projects. If you are very interested in blockchain technology and have technical or financial background, it is suggested to consider starting a business in this area. In terms of protocol system of blockchain, the bottom layer is the underlying technology of blockchain, including the technical protocol of blockchain, as well as some platform routing and basic algorithms; In the middle layer, we need to solve the problems of some application interfaces and the issuance and verification of some certificates, including the services of some instry platforms, big data analysis, etc. This is a rough division, and there should be more detailed division; The top is some applications of blockchain, including financial applications and other applications, Internet of things and so on
Introction to Bubi blockchain
since its establishment, Bubi blockchain has been focusing on the R & D and innovation of blockchain technology and procts, has a number of core technologies, and has made substantial innovation in many aspects, forming a number of core technology achievements, such as: mathematically verifiable distributed consensus technology, fast large-scale ledger access technology, and so on 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
the simple understanding of blockchain is a technology at the bottom of bitcoin, which is also a point-to-point e-cash system, which can realize point-to-point value express. We should distinguish the concepts of bitcoin, bitcoin blockchain, blockchain and blockchain technology. In the countries with more developed finance in the past, the technology of Finance and block has a long history, and the legislation of digital currency and block chain network is also very important. With the advent of the financial era, large financial institutions are studying blockchain technology. They have their own team and concept technology. Graally, regional banks are also participating in the discussion of digital currency. In addition to the application and support of this technology, blockchain has great influence on enterprises. For larger domestic enterprises, Bubi block is also applied to all kinds of equity In the fields of supply chain and points, domestic financial institutions and enterprises have focused on the value of new instries and developed their own blockchain platforms. Blockchain has instantly become a new domestic innovation instry. Overseas, compared with China, the United States has already obtained 15 blockchain patents at the end of last year. The application of blockchain finance is entering a new stage in an all-round way. Various applications will be more and more in-depth, and the relevant changes will attract more and more attention, which will also form a great new trend
financial institutions have launched blockchain technology into a new era of Internet and big data applications, which has laid a pattern from negative interest rate profit driven innovation to technological innovation. At this time, domestic giants have suggested that the cooperation alliance not only affects the implementation of financial infrastructure, but also is an important means to expand business cooperation. In terms of implementation, the future payment system securities deposit will not only affect the implementation of financial infrastructure, It is inseparable from the financial and settlement system and big data analysis, while the domestic giants join hands and propose a mutually beneficial cooperation mode, which can not only effectively improve operational efficiency, but also rece costs and find new growth points, After the adoption of blockchain technology, whether the company's procts and services can proce a new business model or a cost advantage far lower than that of competitors
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. However, because the blockchain is a technology based on mathematical algorithm, the establishment of trust relationship between all parties does not need the help of intermediaries or authority centers, and the cost of establishing trust relationship is almost zero (on the premise of the establishment of blockchain financial infrastructure and ancillary infrastructure), and the blockchain code is open-source, no geographical restrictions, and the network pattern is distributed and interconnected, It lays a technical foundation for the establishment and development of Inclusive Finance and shared finance in the future, and creates material conditions for the integration and unification of global finance. From this point of view alone, blockchain technology is bound to establish a core position in the future financial development, and rely on and complement each other with finance, and win-win in the future.

Blockchain platforms include Ethereum, Asch and other underlying application development platforms
Ethereum, an open source public blockchain platform with smart contract function, provides decentralized Ethereum virtual machine to process point-to-point contract through its special cryptocurrency ether (ETH)
arch, a decentralized application platform based on side chain technology. Asch is designed to lower the threshold of developers, such as using JavaScript as the application programming language and supporting relational database to store transaction data, which is believed to be very attractive to developers and small and medium-sized enterprises
extended data
in 2008, Nakamoto first proposed the concept of blockchain. In the following years, blockchain has become the core component of electronic currency bitcoin: public account book for all transactions
by using peer-to-peer network and distributed timestamp server, the blockchain database can be managed independently. The blockchain invented for bitcoin makes it the first digital currency to solve the problem of repeated consumption. Bitcoin's design is a source of inspiration for other applications
bitcoin is the absolute mainstream of digital currency, and digital currency is in full bloom. Bitcoin, litecoin, dogecoin, dashcoin are common. In addition to currency application, there are various derivative applications, such as Ethereum, Asch and other underlying application development platforms, as well as NXT, SIA, bitstocks, maidsafe, ripple and other instrial applications
8. Boscore should be the most powerful technology now. Before, the technology masters in the EOS community did it. The technology is very powerful. The 3-second transaction speed is the fastest in the world. You can go to the official website to learn more about it and see the white paper. It's my honor to take my advice. Thank you. I wish you a happy life!
9. This is a more professional problem, we need to find a professional understanding to explain. However, open source projects such as bitcoin, Ethereum and decent can be used for reference. You can study them
of course, blockchain itself is only a kind of technology, which has two sides.
