Traditional distributed and blockchain technologies

1. blockchain is a kind of distributed ledger technology. By safely storing information across multiple systems, and by creating reliable "truth" sources, it realizes the intermediary of so-called "trust intermediary", so as to realize point-to-point transactions. Relying on secure distributed storage for verification brings a paradigm shift of trust building, which has a profound impact
in the future, jinwowo network technology will continue to tap the value of blockchain technology in the commercial field, give full play to the advantages of big data services, add value to user behavior, break the ice for the development of small and medium-sized enterprises, and build a real, efficient, safe and honest Internet community of destiny.

2. Blockchain technology uses mathematical methods to achieve distributed accounting and solve the trust problem, so as to complete the decentralization, which will bring far-reaching influence in many fields such as communication, finance, Internet of things, government management and so on
blockchain refers to the technical solution of collective maintenance of a reliable database through centralization and distrust in the past, and it is a technical way for the whole people to participate in bookkeeping. Previous bookkeeping methods were all centralized and needed centralized intermediary, whether it was traditional government, financial institutions, notarization institutions or emerging e-commerce platform and online payment platform
in economic hypothesis, information is sufficient. In fact, it is precisely because of insufficient information that there are very large intermediaries. The existence of intermediaries increases the transaction cost and raises the transaction threshold. In essence, blockchain technology is a large-scale collaboration tool. It makes direct value transfer possible by using pure technology for the first time, and continues the trend of Internet decentralization and disintermediation. Disintermediated blockchain technology will greatly subvert the information intermediary instry
blockchain technology is the basic technology for building bitcoin data structure and encrypted transmission of transaction information, which realizes the issue and transaction of bitcoin. The core of blockchain technology is that all the current participating nodes jointly maintain the transaction and database, so that the transaction is based on the principle of cryptography rather than trust, so that any agreed parties can directly carry out payment transactions without the participation of a third party
technically, a block is a data structure for recording transactions, reflecting the capital flow of a transaction. In the system, the transaction blocks are connected to form a main chain, and all the nodes participating in the calculation record the main chain or part of the main chain
a block contains the following three parts: transaction information, hash formed by the previous block and random number. Transaction information is the task data carried by the block, including the private keys of both parties, the number of transactions, the digital signature of electronic currency, etc; The hash hash formed by the previous block is used to connect the blocks and realize the sequence of past transactions; Random number is the core of the transaction. All nodes compete to calculate the answer of the random number. The node that gets the answer the fastest generates a new block and broadcasts it to all nodes for updating, so as to complete a transaction.

3. "A network-based computer processing technology, corresponding to centralized. As the performance of personal computer has been greatly improved and the popularity of its use, it is possible to distribute the processing power to all computers on the network. Distributed computing is a concept opposite to centralized computing. The data of distributed computing can be distributed in a large area

4. One is that each node of the blockchain stores complete data according to the block chain structure. Traditional distributed storage generally divides the data into multiple copies according to certain rules
Second, the storage of each node in the blockchain is independent and has the same status, which relies on the consensus mechanism to ensure the consistency of storage, while the traditional distributed storage generally synchronizes data from the central node to other backup nodes
data nodes can be different physical machines or different instances in the cloud
the above is the difference between the blockchain technology of jinwowo network analysis and the traditional distributed storage, for reference.

5. 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.
