What is centralized and decentralized

1, efficiency is different: decentralized efficiency than the centralized network efficiency, but in turn the centralized network is more secure. Overall the centralized network is suitable for applications with high security.

2, different characteristics: centralized network is every time two client computers communicate through the server. And decentralized network is the initial need to go through the server, the later communication does not need a server.

3, the cost is different: the collective maintenance of the blockchain features can reduce the cost of many. The centralized network involves a lot of system maintenance, confidentiality, operation, and so on, and these must require a lot of human, financial, and material resources, and these for the decentralization of the blockchain is something that simply does not exist, so it can save a lot of costs.
