Satoshi Nakamoto's revolutionary creation on the consensus protocol opened a new era of decentralized computing. People can freely contribute resources and obtain benefits in a fair and open network, and the decentralized ledger will honestly record all decisions made on the network without any privileged parties. The development of decentralized protocols looks similar to the early Internet protocols, but in essence they have achieved true decentralized autonomy, and a brand-new value delivery network at the upper level has also been born. However, the information era has developed for decades, and the actual production business has given birth to a large number of infrastructures, including database system, network protocol, file system, virtualization, etc. Also because of the infrastructure booms, Internet can support the upper-level application system.
