Where is the blockchain server
but if we have to compare them, we can first see the differences or connections between the two characteristics
the traditional server is centralized
take a look at the figure below, it is a typical centralized network, the most central is the server, the others are clients, the server is responsible for providing services to all clients, and the client obtains services from the server, such as downloading files.
with the development of the Internet, data are stored in the storage server, the security of data can not help everyone's worry. Blockchain technology, using cryptography to ensure the security of data transmission and access, in the process of data extraction, can realize the centralized use of unstructured data required by various research, so as to make the storage server data secure
the 10th party provides IT hardware solutions for enterprises such as server leasing and sales, and has a wide range of cooperation instries, including Internet, blockchain, scientific research institutions, rendering design, intelligent manufacturing, etc.
Blockchain is a special network account book. The core of blockchain technology is digital encryption. As early as 1991, a group of young people invented a new set of mutual authentication encryption technology in order not to tamper with the date of electronic documents. By means of cryptography, they concatenated and protected the concatenated text records (also known as blocks)
blockchain stores data in blocks, and each block is queued in strict order to form a "chain". If someone wants to change the content of a block, the unique characteristics of the block will also change, and the following blocks will not recognize it immediately, and the "fake" block will have to break away from the chain
extended data
users all over the world can connect their servers to the blockchain network and become an independent node in the distributed database storage system. Once joined, the node will enjoy the same rights and obligations as all other nodes
therefore, people who carry out services on the blockchain can read and write to any node in the system. All nodes in the world will synchronize again and again according to some mechanism, so that the data of all nodes in the blockchain network is completely consistent
because of the two characteristics of immutability and decentralization. Blockchain is a good solution to the problem of trust in modern commercial society. It has emerged in financial services, Internet of things, public services, social welfare and supply chain management
