Blockchain prototype
in short, blockchain is a community-based technology, which can make value exchange more secure. Blockchain is their name
therefore, chain operation has a huge impact on the people, creating the greatest value for the enterprise and bringing more convenience to the people strong>
Blockchain is a new application mode of distributed data storage, which is an important concept of bitcoin. At present, there are 35 stocks associated with the blockchain concept in the A-share market, of which 6 blockchain concept listed companies are traded on the Shanghai Stock Exchange, and 29 blockchain concept listed companies are traded on the Shenzhen Stock Exchange
according to the correlation of blockchain, the leading stocks of blockchain concept stocks are most likely to be born from Xinchen technology, luyitong and Sifang Jingchuang
Xinchen Technology: on September 29, 2016, the company said in the interaction that the company is now doing research and development of blockchain technology
Lu Yitong: the company plans to raise 67.9691 million shares of additional shares of RMB 24.57 per share, and the total amount of supporting funds will not exceed RMB 1.670 billion, which will be used to pay the cash consideration of this transaction, construct the block chain ASIC chip instrialization project, artificial intelligence ASIC chip R & D center, chip proct marketing and service network, etc
Sifang Jingchuang: on May 31, 2016, the inaugural meeting and the first general meeting of the financial blockchain cooperation alliance (Shenzhen) was officially held in Shenzhen Wuzhou Hotel, and the company was one of the members of the meeting
blockchain technology has several characteristics, such as decentralization, distributed storage, traceability and non tampering
the building owner can judge from the above characteristics. Decentralization means that everyone can view the data of the application of blockchain technology, but it can not be tampered with, and it will not lose data e to a single node, so we can see the source of each application. Some fans of Nanning blockchain development also have some understanding of these applications< br />
In recent years, blockchain and artificial intelligence have been very popular
first of all, blockchain is to establish a decentralized network. The so-called decentralization means that the network does not belong to you or me
it belongs to everyone
Artificial intelligence is a new technology science that researches and develops the theory, method, technology and application system for simulating, extending and expanding human intelligence. In other words, "machine self-learning"in this way, we can think about the combination of blockchain and artificial intelligence
first of all, we need to understand that blockchain can be divided into three stages
However, in the first three stages, there are some problems, such as the lack of decentralization, low scalability, the mismatching between the incentive of the blocker and the best profit of the whole network, and the network always running at the maximum capacity. Serious waste of resources and rece efficiencyso can we combine artificial intelligence with underlying public chain technology to solve these problems
The answer is yes! And there has been team research and development, and has made a certain progressVelas is a public chain that enhances its consensus algorithm through artificial intelligence (AI) optimized neural network, and carries out self-learning and self optimization. It is committed to improving the security, interoperability and high scalability of the transfer process and intelligent contract. Velas adopts the dpos consensus enhanced by AI, which completely realizes decentralization without recing the security and transaction speed. Not only that, AI chooses who to mortgage the token according to the needs of the blockchain; Velas only blocks when needed; Every 1 second to every 2 minutes; Scalability (up to 30000 TPS); Block procers are selected by artificial intuition
Characteristics of blockchain
one of the four characteristics of blockchain: tamper proof
the most easily understood characteristic of blockchain is tamper proof
tamper proof is based on the unique account book of "block + Chain": the blocks with transactions are added to the end of the chain in time order. To modify the data in a block, you need to regenerate all blocks after it
one of the important roles of consensus mechanism is to make it almost impossible to modify a large number of blocks at high cost. Take the blockchain network (such as bitcoin and Ethereum) with workload proof as an example, only with 51% of computing power can all blocks be regenerated to tamper with data. However, the destruction of data is not in line with the self-interest of players with large computing power. This practical design enhances the reliability of data on the blockchain
generally, the transaction data in the blockchain ledger can not be "modified", it can only be "modified" through the new transactions that are approved. The process of correction will leave traces, which is why the blockchain can not be tampered with. Tampering refers to changing or misinterpreting by means of forgery
in today's common files and relational data, unless a special design is adopted, the system itself does not record modification traces. Blockchain ledger adopts a design different from that of files and databases. It draws on the design of ledger in reality, that is, to retain the traces of records. Therefore, we can not "modify" the account book without leaving traces, but can only "modify" the account book (see Figure 2)
Figure 6: bitcoin is centralized in the organization and logically centralized
when we imagine the future organization, the ideal prototype in our mind is often bitcoin organization: completely decentralized autonomous organization. But in practice, for the sake of efficiency and advancement, we will move closer to the centralized organization and finally find a suitable balance point
nowadays, in the blockchain projects that are created and issued through the smart contract of Ethereum and run in a community or ecological way, the ideal state of many projects is similar to the bitcoin organization, but the actual situation is between the completely decentralized organization and the traditional company
when we discuss the fourth feature of blockchain, which is decentralized self-organization, we are actually going out of the code world, involving human organization and collaboration. Now, various discussions and practical explorations have also revealed the significance of blockchain beyond technology: it may serve as an infrastructure to support human proction organization and collaborative change. This is another example of the complete isomorphism between blockchain and Internet. Internet is not only a technology, it has changed people's organization and collaboration
in general, Ethereum has brought blockchain into a new stage. When discussing Ethereum, if we want to summarize two key words, they are smart contract and token; If I can only say one, I will choose "Tong Zheng". I would rather look for its meaning from the history of the Internet and repeat the previous analogy: as a token of value, its role is similar to HTML. With HTML, what kind of website to build depends entirely on our imagination
the application of blockchain in digital currency has been proved to be a feasible solution. At present, the mainstream digital currency in China basically uses blockchain technology. For example, bitcoin, Puyin, lightcoin, Ethereum classic, etc.
