1. Concept analysis of blockchain: it is not only a concept but also a technical system
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.

4. During September 4-7, 2019, CIOE will hold relevant meetings. The following is an introction to the 2018 Asia Pacific blockchain and artificial intelligence Innovation Forum exhibition last year. I believe that the exhibition in 2019 will be more professional and breakthrough
APCA (Asia Pacific cloud application alliance) and bcai (Asia Pacific blockchain and artificial intelligence innovation and Application Research Institute) will jointly hold the "2018 Asia Pacific blockchain and artificial intelligence Innovation Forum (Shenzhen)" in the conference hall of hall 3 of Shenzhen Convention and Exhibition Center on the afternoon of September 6, 2018 (Thursday)
blockchain block chain is considered to be the fourth generation of disruptive core technology after steam engine, electric power and Internet. As a machine for building trust, blockchain will completely change the way of value transmission of the whole human society, making the information internet a value Internet
blockchain is of revolutionary significance. It will reshape the fulcrum of the world economy. Because it uses decentralized disruptive technology, it can "reshape instry services and business architecture". As the most popular vocabulary, blockchain technology has rapidly gathered the high focus of the government, science and technology and financial circles
in 2016, the Chinese government wrote "artificial intelligence and blockchain" into the 13th five year plan, and blockchain technology was listed in the National Informatization Plan of the Chinese government for the first time. At the present stage, AI and blockchain technology are paid more and more attention by government agencies and international organizations. In 2018, artificial intelligence will affect our lives in a tangible way. In 2018, artificial intelligence will become the mainstream and begin to influence all aspects of our lives in a truly ubiquitous and meaningful way
in order to further promote the innovative application and development of blockchain technology and artificial intelligence technology, let blockchain technology serve the real instry and digital economy, further promote the instrialization process of blockchain technology and artificial intelligence technology, and serve the public entrepreneurship and innovation, APCA and bcai will invite BC and AI experts from Silicon Valley, Singapore, Hong Kong, Tokyo, Beijing, Shanghai, Guangzhou and Shenzhen as well as manufacturers of excellent technologies, procts and solutions to participate in this forum, The forum will exchange and introce the relevant innovative applications and development trends with the participants, so as to help enterprises better participate in the field of blockchain applications and artificial intelligence applications and obtain greater development opportunities. At the same time, interpret the pitfalls and opportunities in the application, and help enterprises realize the marketization and digital capitalization of blockchain technology and artificial intelligence technology procts
nowadays, the innovative application of blockchain is a great force. It can provide a trust tool to expand the global business opportunities of enterprises
nowadays, the innovative application of artificial intelligence is an outlet, which can provide an intelligent service and facilitate people's work and life
when blockchain 3.0 / 4.0 comes, are you still hesitating and waiting
when neural network computing is applied, you haven't got on the bus yet
the future has come, are you here?

5. No, these three are not compatible with each other and each has its own purpose
choose your own direction
the cost of developing an interface is not so high. Except for EOS, there is not much data to be chained, which is basically completed locally. As a top blockchain technology developer in China, weisanyun is still a good technology developer.

Below 63 layers of the ground, it needs to be excavated with stone pick. There are many holes below. First, make some ladders and start to dig down. Dig a grid and put a ladder to climb up. Iron ore and coal are almost the same length. Pay attention to distinguish. It's easy to find in the natural mine, but the natural mine is very dangerous, at least a suit of iron, bow and sword in hand can be safe
7. In wotchain parallel distributed architecture, distributed cloud storage layer and blockchain layer are two parallel distributed networks for
data storage and computing tasks respectively. In the client, the user data is encrypted into blocks, and each
part will enter a different storage node, and the hash credentials will be uploaded to all nodes in the blockchain network, so that the data can be
verified, confirmed, and so on. The parallel distributed architecture separates the data layer from the blockchain, which not only ensures the security and centrality of the blockchain system, but also improves the scalability of the system and greatly reces the size of the block
at present, many blockchain platforms are facing the problem of capacity expansion, such as: block capacity, but only increasing the block capacity
will increase the maintenance cost of blockchain nodes, resulting in the rection of the number of nodes and the rection of system security. With the system architecture of
wotchain, the number of transactions packed in a single block can be greatly increased under the same block size,
the transaction processing speed of the platform can be greatly improved< Wotchain
for the Internet of things and ecological network, and for all the data that can be obtained, perceived and processed, wotchain
mainly does two things well: the first is to ensure that the data is reliable; The second is to ensure the circulation of data value.
