2020 will be the beginning of the real rise of blockchain. Blockchain is not a new technology, but a building block innovation in Satoshi Nakamoto, which is a model innovation. It should be understood abstractly, not as a metaphor in the technical field. Some people define it as relations of production, which is very enlightening. Blockchain will not subvert anything, and blockchain provides another option. Just because the black swan is beautiful, it doesn't mean to replace the white swan. For ordinary people, blockchain provides a new choice, which is a very good thing. The blockchain is a new thing, which theoretically produces the next BAT, so it is necessary to embrace him. This is the category of professional outlook and outlook on life.
In the digitalization process of various industries, the Internet of Things technology will support the trusted mapping of data in the offline world and online, and the blockchain technology will promote the reorganization and optimization of trusted data in the circulation path, thus improving the efficiency of circulation and collaboration. In many scenarios such as cross-border remittance, supply chain finance, electronic bills and judicial deposits, blockchain will begin to integrate into our daily lives. With the embodiment of the value of "link", layered architecture and cross-chain interconnection will become the technical basis for the scale of blockchain. The blockchain field will return to rationality from excessive fanaticism and pessimism, and commercial applications are expected to accelerate.
First of all, the main function of blockchain is to store information. Any information that needs to be saved can be written into or read from the blockchain, so it is a database. Secondly, anyone can build a server, join the blockchain network and become a node. In the world of blockchain, there is no central node (decentralization), and every node is equal, keeping the whole database. You can write/read data to any node, because all nodes will eventually synchronize to ensure the blockchain is consistent.
