the core problem of blockchain solution is not "digital currency", but how to establish a "trust" ecosystem to meet the occurrence and development of economic activities under the environment of information asymmetry and uncertainty. This problem is called "Byzantine general problem", or "Byzantine fault tolerance" or "two armed forces problem". It is a difficult problem in the process of information machine interaction in a distributed system, that is, when any node in the whole network can't trust its counterpart, How to create a consensus basis for secure information interaction without worrying about data tampering

blockchain uses algorithmic proof mechanism to ensure the security of the whole network. With it, all nodes in the whole system can exchange data automatically and safely in a de trusted environment. For details of Byzantine Generals, please refer to relevant papers

the second meaning of blockchain is to realize transnational value transfer. At the beginning of the birth of the Internet, the core problem to be solved is information manufacturing and transmission. We can quickly generate and information to every corner of the world with network through the Internet, but it still can not solve the value transfer and credit transfer. The so-called value transfer here means that everyone in the network can recognize and confirm the way to transfer a certain part of the value accurately from one address to another, and it must be ensured that after the value transfer, the original address reces the transferred part, while the new address increases the transferred value. The value mentioned here can be monetary assets, some physical assets or virtual assets (including securities, financial derivatives, etc.). And the results of this operation must be recognized by all parties, and the results can not be manipulated by any party

in the current Internet, there are various financial systems, and there are many payment systems provided by banks or third parties, but it still relies on centralized solutions. The so-called centralized solution is to place all the value transfer calculations in a central server (cluster) through a certain company as endorsement. Although all the calculations are automatically completed by the program, the centralized person or organization must be trusted. In fact, to solve this problem through centralized credit endorsement can only limit credit to certain institutions, regions or countries. From this we can see that the fundamental problem that must be solved is credit. Therefore, the core issue of value transfer is transnational credit consensus. In such a complex global system, it is very difficult to establish a global credit consensus system out of thin air. Due to the different political, economic and cultural situations of each country, it is almost impossible to achieve complete mutual trust between enterprises and governments of the two countries, which means that whether the endorsement is made with the credit of indivials or enterprises or governments, Even if the value exchange between countries can be completed, it also has huge time and economic costs. But in the long history of mankind, no matter how different the religion, politics and culture of each country is, the only thing that can reach a consensus is mathematics (Basic Science). Therefore, it is no exaggeration to say that mathematics (algorithm) is the greatest common divisor of global civilization, and it is also the basis for human beings to obtain the most consensus. If we take the mathematical algorithm (program) as an endorsement, all the rules are built on an open and transparent mathematical algorithm (program), so that all people with different political and cultural backgrounds can reach a consensus

future development? The Internet will make the global interaction more and more close, accompanied by a huge trust gap. At present, the existing mainstream database technology architecture is private and centralized, which can never solve the problem of value transfer and mutual trust. Therefore, blockchain technology is likely to become the next generation of database architecture. Through decentralization technology, we will be able to complete the great progress of mathematical (algorithm) endorsement and global mutual trust on the basis of big data

blockchain technology will not only be applied in the field of financial payment, but will be extended to all the current applications, such as decentralized microblog, wechat, search, rental, and even taxi software. Because blockchain will allow human beings to conct large-scale cooperation in a way of no geographical restrictions and no trust

Bubi blockchain uses cryptography provable algorithm to build multi center network trust, which is open, transparent, tamper proof and revocable; Multi party participation in information transparent sharing, the establishment of authentic traceability chain path, direct to consumers

our generation is likely to be lucky to experience two of the most amazing events in human history. All people and all machines on the earth have launched unprecedented large-scale collaboration with unprecedented mutual trust through blockchain technology. Secondly, based on this, real artificial intelligence will be created. These two times will profoundly change the economic development mode of the world. Entrepreneurs, entrepreneurs, scientists and all kinds of geeks will use this abundant world to create something that can shock and delight us
