Decentralization case
blockchain is a distributed shared ledger and database, which has the characteristics of decentralization, distributed storage, encryption algorithm, whole process trace, traceability, collective maintenance, openness and transparency take taking charge of Department funds as an example, the traditional way is to assign a person in the Department to keep accounts and manage the Department funds. This person can directly manipulate the remaining amount or the amount of each use, and make profits from it by taking advantage of his authority. This is the traditional centralized management and in the blockchain management mode, , everyone in the Department has a fund use book, which is added by relevant personnel, and synchronized to their own book after other personnel check. Each transaction will record the usage time, user, amount and content of funds, and generate corresponding serial number for marking. The serial number of each transaction will be stored together with the usage of the next transaction. Each bookkeeping will be encrypted, and so on. At the same time, the account book of each person in the Department is visible to everyone outside, and anyone can query the use of each fund through the account book in the management mode of blockchain, multi person synchronous bookkeeping is "decentralized management" everyone in the department checks and stores it, which is called "consensus mechanism" everyone records the use of each fund, which is called "distributed storage" the serial number generated by the detailed usage of each fund is called "hash value" store the serial number and the usage of the next fund, which is called "whole evidence chain" everyone's account book is visible to everyone outside, which is called "openness and transparency" to query the usage of each fund is called "traceability" if someone wants to tamper with a certain amount of funds, the serial number of the funds will be changed accordingly, and this person needs to tamper with all subsequent account records on the account book and the account book records of all people. However, this can be realized on the premise that it can crack the encryption processing of everyone's every bookkeeping. Moreover, once the system finds that there is an account book different from everyone's, the blockchain will automatically correct the "wrong" account book. This can fully guarantee the originality and non tamperability of blockchain electronic data 
centralization has the advantage of centralization, which should not be too one-sided.
