The transaction cost of blockchain is too high
blockchain is a distributed system, which is constructed by cryptography. Indeed, blockchain is a technical collection of concepts formed by distributed system and cryptography. We should emphasize that it is not only a concept but also a technical system, At the very beginning, blockchain only represented the account structure of the underlying technology of bitcoin. It was a narrow concept. At the beginning, because the development of this technology should be represented by a special term to distinguish it from bitcoin, this word was used to refer to it, and it became a bigger and richer concept and a complete system
when we think back to cloud computing, cloud computing existed before the word cloud computing was put forward. However, once cloud computing was put forward, it developed rapidly along the concept of cloud computing. I think blockchain also has such characteristics, and it will continue to develop. Once it becomes a complete sub Technology system, all the technologies in the sub fields under blockchain will continue to develop, The algorithms in the sub domain will develop in the direction of qualitative change in the way of adding tests. Blockchain is a kind of distributed line or network trust technology. When I studied blockchain technology, there was no blockchain word. We called it distributed computing. On the technical level, end-to-end. From a macro point of view, the blockchain is composed of multiple nodes participated by Dongfang. It is equal. The cooperation of these nodes needs to complete the mutual verification on the blockchain. At this time, there is no need for a central node to do this
macro: distributed equal deployment system, participating nodes cooperate to complete verification and storage
microcosmic: rigorous data structure is packaged and stored in the block, and logically concatenated to form a chain
digital signature and integrity verification ensure the authenticity, real-time and timing of block data
at last, after learning all the technical features, it has achieved the multi fight, informed group and supervision right, because it is transparent, shared and open. All parties of the alliance should participate in the operation of the blockchain system, which is equivalent to a co construction, sharing, sharing and co governance. When constructing the alliance, I have to think of one thing: what I store to the blockchain, which are transparent and which are encrypted. At this time, I need to determine according to your business system. If someone deliberately cheats, he or she will probably find that your data may be tampered or forged with the participation of the public or even the collective alliance, so he or she will consider the cost of doing evil. In this way, the trust cost of the alliance will be greatly reced, and there will be no friction. Outside the alliance, because you believe that you have adopted the blockchain technology, you will have a higher degree of trust in the services or procts provided by the whole alliance, so this is a very good way of virtuous circle
what should you do to build a blockchain system or to bridge business to a blockchain system? There are two steps, very simple. The first step is to construct several key roles in your business logic. Now consider how many roles there may be. There may be many roles, but now consider them as one. These perspectives must be related in business logic. They need to share and map these rules to the blockchain or put them into scripts at the same time. Next, we will talk about data, which data will be put into the blockchain and which will not be put, because the efficiency of the blockchain is security, which is generally simple and key, and only what needs to be built together is considered. On the other hand, even if some data are put into the blockchain, not all things need to be supervised, but may be closed door, and can only be seen after authorization, One is privacy, the other is regulatory compliance
after the first step, the second step is simpler. You need a convenient and reliable blockchain platform. It is an underlying infrastructure, including books, networks, supply and demand algorithms, and accounts. All these things have to exist. After general checking, you can check and send these four blocks according to your business needs. There is a protocol below. The above layer is mapping. This mapping layer is very important. It abstracts your business into many models and logics, and abstracts them into an easy-to-use system. Then you can develop your business logic on the application system, and then develop the business logic based on the blockchain. This is a fast process. In fact, a good blockchain business platform should have its own application tools, as well as monitoring, viewing and auxiliary tools, just like the early days of the database. At the beginning of the database, if it was just data without auxiliary tools, it would be very difficult to run
next, let's share a small case, which is the case of blockchain business points that we just released. There are a lot of views that we have already discussed. We must use points to make it universal, so that consumers can get profits and businesses can rece the burden. Moreover, we can let points flow and guide real secondary consumption. This is of great significance. We have to consider more when we choose commercial competition. Commercial competition itself has a certain financial or monetary attribute. It is a purely low-risk number, because it has the lowest regulatory risk to the extent of compliance and legality. Second, points can quickly accumulate digital assets, accumulate C-end users, test your blockchain platform to a certain extent, and even test your blockchain technology to verify whether your blockchain platform is right. Finally, derived with financial related attributes, for the expansion of financial means behind all laid a good foundation
according to the path of building a blockchain system that we have just seen, the first step is to make decisions. In the blockchain system, it plays two roles: merchant and consumer. Merchants are also divided into two levels, the points they send, the points they receive, and the points they receive are also divided into two levels, the points they transfer out and the points they receive. Rules are non discrimination rules; Data, integral, some data are very interesting. I can write all the people on it, and I can write the effective information on it. There are some consumer behaviors, such as what to buy, coffee or bread. These data are written on it. I will use a simple example to guide you
the second step is to find a platform for blockchain. In our Bubi blockchain, what do we get? We really got a positive feedback. We think it's a very good feedback. First, digital integral represents a variety of data assets, which can be supported on the blockchain. Second, it may have many users, whether real users or laboratory simulation users. It's no problem to support millions of transactions and storage. Third, it really builds a good foundation for us, which lays a good foundation for the exploration in the financial field.
there are many kinds of blockchain digital wallet apps. For example, online applications can be divided into many kinds, including full node wallet, light wallet and centralized wallet. In addition, they can be divided into single chain wallet and Multi Chain Wallet, while offline applications can be divided into paper wallet and hardware Wallet
the development costs of different types of blockchain digital wallets are very different. For example, the development costs of single chain wallets and Multi Chain wallets are different because of the different system types used in the development. It can be known that the development of Multi Chain wallets is more difficult, because the quotation will be much higher than that of single chain wallets.
blockchain is the core supporting technology of digital cryptocurrency system represented by bitcoin. The core advantage of blockchain technology is decentralization. It can realize point-to-point transaction, coordination and cooperation based on decentralized credit in a distributed system without mutual trust by means of data encryption, time stamp, distributed consensus and economic incentive, so as to solve the common high cost, low cost and low cost of centralized institutions Low efficiency and data storage insecurity provide solutions
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.
The global well-known blockchain trading platform can refer to the following figure:
there are many similar platforms, which can be viewed on non small platforms. The market of digital assets fluctuates a lot, and no one can say for sure. Compared with the previous boom, the current market is in the cooling stage

The characteristics of blockchain technology, such as decentralized credit, tamper proof and programmable, make it widely used in digital cryptocurrency, financial and social systems. The domain names related to blockchain, such as. Top, have also been registered under the wave of blockchain, and many trading platforms can see relevant applications.
1. The legal knowledge of the legal manuscripts: go with the law
the legal system is a fair rule, which is based on justice and by means of the enforcement of a country's coercive force. The main contents of the hand copied newspaper are: the slogan of "law popularization and publicity" in the fifth five year plan, general ecation, the meaning of crime, traffic safety and legal publicity
2 legal knowledge of legal hand copied newspaper: Legal garden, little lawyer
in our life, because of the law, the legal system makes more personal protection and rights maintenance. The main contents of hand copied newspaper are: juvenile law, what to do when someone calls at home alone, and the theme of legal publicity activities over the years
3, the legal knowledge of legal hand ing: the garden of popularizing the law
law is a fair rule, which takes the guarantee of national coercive force as the means. The main contents of the manuscripts are: publicity slogans, ecation, the meaning of crime and what to do in case of kidnapping.
architectural design, facilities and equipment, and what is the theme
now I would like to recommend the design of some youth activity centers that we have done in Shanghai Golden Point art, hoping to help you
the design mainly reflects the youth's dedication to build five "shining constellations" such as popular science, morality, gratitude, enlightenment and interaction We should carry out a variety of popular science ecation activities for young people in various ways, such as inspiring ideological and moral ecation, lively growth ceremony and thanksgiving ecation, self-improvement "creation" ecation, international and regional cultural exchanges across time and space, and cultivate young people's scientific literacy, ideal sentiment, civic awareness, creative thinking and open vision, By creating constellations, we can light up the starry sky for the healthy growth of teenagers. The activity center will focus on the various needs of the growth and development of young people and youth, create five "frontier squares" including learning square, talent square, training square, entrepreneurship square and Exchange Square, and provide all-round training of young people's science and technology, art, interest and specialty, consulting agency, agency and recommendation services for young people, and training of young people's Vocational and technical talents, Youth entrepreneurship integrated solution service, youth study abroad, training, investigation, research and other services, to help young people and youth to establish life coordinates
for the scene simulation / tree / ship / spaceship / simulated architectural design in the activity center, we use the most commonly used PU procts abroad. This proct is honored as the modeling magician Series in China. It has outstanding expressive force in the simulation modeling, and is used in the simulation scene modeling design, outdoor three-dimensional advertising, museum building decoration
the project case is kubeira in Changsha and Du city in Hangzhou.
