Briefly record the understanding of "decentralization" and "distribution"
Decentralized is a network topology that has been proposed for a long time and widely used. Its nodes are decentralized, but it can have a center or go to the center. An obvious example, in order to ensure the playback experience of iQiyi, its playback network is distributed, but it is a centralized service.
Decentralized (decentralized) is a governance model, which is proposed along with the blockchain, relative to centralization. Decentralization necessarily uses a distributed topology.
In addition, because the current blockchain is divided into public chain, alliance chain, and private chain. We can further divide it like this: Although they are all distributed network topologies, the public chain is decentralized, the alliance chain is multi-centralized, and the private chain is centralized.
