Following big data, blockchain has become a hot topic, focusing on and discussing. The blockchain is expected to be applied in many areas such as supply chain management, food safety, and information dissemination. Virtual digital currency is only one of its application scenarios. The blockchain has gone to the altar for a moment, but do you really understand the blockchain?
What is blockchain technology?Blockchain concept In the simplest and most popular way of stock market, blockchain technology is everyone's bookkeeping, or distributed ledger. In the Internet age, each system has a database, which can be regarded as a book, recording user behavior, such as how much money you bought for Taobao, how much money is used, and the year-end Alipay keyword will count your account for one year. Give you a keyword. This is a centralized ledger. The blockchain is “decentralized,†which allows every member of the system to participate, not only for everyone, but also for a complete account by linking.
Blockchain technology is a collection of multiple technologies at the bottom of the Internet, including P2P communication protocols, distributed storage database technology, encryption algorithms, consensus algorithms, etc. Through the integration of these technologies, a time-series, block-by-block record is created. The mode of the data. All data is backed up in a database structure at all nodes, achieving decentralized, peer-to-peer transmission, transparent, traceable, non-tamperable, data security and credit self-establishment. Xiao Bian feels that the blockchain is mainly based on a transparent trust system involving everyone and realizes information sharing. The imagination is very large, but it is definitely not as omnipotent as you think.
From the above conceptual understanding of the blockchain, as a new concept of data storage, transmission, and proof, the biggest advantage of the blockchain is to ensure that important information is not tampered with. However, Xiaobian wants to say that although the blockchain is deliberately exaggerated, its function is limited, neither to renovate the business operation process nor to automate the work of different functions. Therefore, some arguments claiming that the blockchain will cause the original organizational model to abandon, have to say that you have played
Blockchain is confused with artificial intelligence.In fact, from the perspective of enterprises, the purpose of introducing artificial intelligence is to save costs and improve efficiency. So it is not difficult to imagine that the standardized, streamlined part is the first to be replaced. So the entire workflow will be broken and reorganized due to the access of artificial intelligence, resulting in a new mode of operation. The blockchain is for information security, and the two are completely different concepts.
Blockchain deployment must be done by each participant.When we mention the blockchain, we always emphasize the participation of each member. Many people think that the blockchain construction needs everyone to do it. This is not correct. For the traditional public chain model, anyone can participate in the construction of the system, that is, the system participants can run a node, of course, or not. For blockchain systems used in commercial environments, the access mechanism of blockchain nodes is limited. Not all users need to participate in node construction. Some important users may participate in node construction, most users. It is directly using the blockchain service. So service and operation and maintenance are two different things.
The blockchain must be without an intermediary or a center.Based on the characteristics of the decentralization, it is easy to understand the blockchain without success. However, what we have to figure out is that the blockchain connects the services on a decentralized basis, and provides services for all users on the chain through various services. These services are always provided by the center, so these special centers can be understood as intermediaries, which promotes the activity of the blockchain system.
On January 23, a shipment of US soybeans shipped to China became the first agricultural product to be traded using the blockchain. The explosion of this news seems to have strengthened people's confidence. However, according to a report, “The maximum transaction size is limited to 1 MB, and there is a confirmation delay of about 10 minutes for each block (depending on the average transaction size), the maximum transaction volume is 7 times/second (tps).†Analyst said "In fact, as the size of the transaction record continues to expand, the volume of transactions has been declining, currently less than 3 tps, compared to peak capacity, such as 47,000 tps for Visa networks or 1 million tps for Nasdaq. A value is really pitiful." Scalability is always a problem.
To achieve blockchain, you must have a smart contract.Now when designing blockchain-related solutions, it is easy to introduce the concept of smart contracts, all of which hope to build automated business logic through smart contracts. Smart contracts should have two characteristics, one is distributed and the other is intelligent. Based on the characteristics of business logic, it is easy to ignore the distribution and pursue the intelligence. Now the centralized software system can realize everyone's demand for intelligence. According to Xiaobian's understanding, some of the current smart contract construction is not satisfactory, so smart contracts can't better meet everyone's intelligent needs, and the function of blockchain does not necessarily need smart contracts to achieve.
The blockchain is equated with bitcoin. Although people around Huaqiang Wisdom Network Xiaobian are talking about blockchain and bitcoin, many people are confused about the two. Blockchain is a technology that is unique to Bitcoin. Bitcoin is intended to be a great experiment on the world's monetary system, because it is a bitcoin to invent regional chain technology. To some extent, bitcoin is the mother of blockchain technology. After the invention of Bitcoin, many people refer to the blockchain implementation in Bitcoin, using a similar technology to achieve a variety of applications, such technology is collectively referred to as blockchain technology. The various chains implemented by blockchain technology are blockchains. So the concept of blockchain is bigger than the concept of bitcoin.
