How to realize distributed blockchain

1. blockchain does not belong to any instry. Blockchain is a new application mode of computer technology, such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and so on. In a narrow sense, blockchain is a kind of chain data structure that combines data blocks in a sequential way according to the time sequence, and it is a distributed account book that can not be tampered with and forged by means of cryptography.

2. That's a good question. Let me give you an example. For example, when I deposit 100 yuan in the bank, the data of this deposit is only recorded in the bank's database, which can't be obtained by others, namely "central bookkeeping". The blockchain is a distributed accounting, a new information recording technology, and it is "encrypted" and "distributed". The data does not exist in a center, but is stored once on the computer of the whole network. For example, if I transfer 100 yuan to you, I will shout to all the computers in the whole network. Let's record the accounts together, that is, "Distributed Accounting".

Sharing area network:

the application scope of blockchain technology is still very wide. Based on the characteristics of decentralization, distrust, collective maintenance and reliable database, its application in the financial instry is the first step
blockchain is the underlying technology of bitcoin, and the application and development of blockchain in digital currency is mature

like the block chain based trading system development scheme provided by Yingtang Zhongchuang, the developed software system has great safety factor and transparency

Seeing some answers to the debate on the definition of blockchain, I suddenly realize that my answer to this explanation principle has always been directed at bitcoin. There is no specific and unique answer in the instry between the definition of blockchain. Here I first summarize the characteristics of "blockchain" according to the papers I read:

1; Hash chain & quot There are several nodes participating in the system operation (distributed)

3. Reach a consensus on the consistency of basic data (consensus agreement / algorithm) through a certain protocol or algorithm

since bitcoin is currently one of the most typical and influential applications of blockchain, it will be much easier to understand how bitcoin uses blockchain before understanding other forms of blockchain applications

5. Chongqing jinwowo analysis distributed consensus algorithm:
the blockchain system uses the distributed consensus algorithm to generate and update data, which eliminates the possibility of illegal tampering with data from the technical level, thus replacing the third-party intermediary institutions in traditional applications to ensure trust and transaction security, and recing the time cost, human cost and resource consumption caused by maintaining credit.

6. Doctors and nurses are different. Interns have accommodation allocation, but it's not very good. Nurses don't have it. They rent their own houses

7. Distributed applications are software applications that are mainly stored on cloud computing platform and run on multiple systems at the same time. These systems run on the same network and communicate with each other to complete specific tasks or commands. With distributed application program; Traditional applications need a system to complete the assigned tasks
by storing information blocks among nodes in the blockchain network, the failure of a system will not make the blockchain bankrupt. When the computer or system fails, other systems will act as backup and keep running, independent of the system that is down. Once all active nodes receive and confirm that the transaction is valid, the block (transaction) will be added to the chain (general ledger) for public access. Even if one or two nodes exit the network, all nodes can still maintain the ability of normal operation, which can ensure that users continuously record and confirm their transactions in an uninterrupted and timely manner<

the Xueshuo innovation blockchain Technology Workstation of Lianqiao ecation online is the only approved "blockchain Technology Specialty" pilot workstation of "smart learning workshop 2020 Xueshuo innovation workstation" launched by the school planning, construction and development center of the Ministry of ecation of China. Based on providing diversified growth paths for students, the professional station promotes the reform of the training mode of the combination of professional degree research, proction, learning and research, and constructs the applied and compound talent training system.

8. Blockchain itself is composed of distributed nodes. Yinying China has started to study and test the blockchain project, and the digital currency crowdfunding platform launched is also very avant-garde
the so-called distributed computing is a computer science, which studies how to divide a problem that requires a huge amount of computing power into many small parts, and then assign these parts to many computers for processing, and finally synthesize these calculation results to get the final results. Distributed network storage technology is to store data in a number of independent machines. The distributed network storage system adopts the scalable system structure, uses multiple storage servers to share the storage load, and uses the location server to locate the storage information. It not only solves the bottleneck problem of single storage server in the traditional centralized storage system, but also improves the reliability, availability and scalability of the system.
