Possible problems of blockchain in voting

1.

blockchain technology is widely used. Under the integration of new technologies, the main application scenarios of blockchain include finance and insurance, intelligent manufacturing, intelligent environmental protection, energy and power, health care, ecation, culture and innovation, smart city, social welfare, agriculture and many other fields

1. blockchain + finance

   blockchain can help financial institutions solve problems such as trust and data sharing

3. blockchain + right art

3. Blockchain + government

in statistics, voting, budget management and other aspects, blockchain can rece costs, improve efficiency, and increase transparency, so as to prevent the risk of failure of centralized system

4. Blockchain + insurance

fraud identification and risk prevention: by placing insurance claims under an unchangeable general ledger, blockchain helps to eliminate the common sources of fraud in the insurance instry

property insurance and accidental injury insurance: policies and shared ledgers recorded in the form of smart contracts can improve the efficiency of property insurance and accidental injury insurance

Health Insurance: blockchain technology enables medical records to be encrypted and shared among health service providers, thus improving the interoperability of the health insurance ecosystem

Reinsurance: the information security of reinsurance contracts on the blockchain platform can be ensured through the form of smart contracts, which can rece the amount of information and simplify the payment process between insurers and reinsurers

A: the main application fields of blockchain technology are finance, Internet of things and logistics, public service, digital right, insurance and public welfare

First, in the field of finance,

blockchain has great potential application value in international exchange, letter of credit, equity registration, stock exchange and other financial fields

Second, the Internet of things and logistics

blockchain can also be naturally combined in the field of Internet of things and logistics. Through blockchain, we can rece logistics costs, trace the proction and delivery process of goods, and improve the efficiency of supply chain management

Third, in the field of public service, blockchain is closely related to people's proction and life in the fields of public management, energy and transportation. However, the centralization of these fields also brings some problems, which can be transformed by blockchain

Fourthly, in the field of digital right, through blockchain technology, works can be authenticated to prove the existence of text, video, audio and other works and ensure the authenticity and uniqueness of ownership

In the field of insurance, insurance institutions are responsible for fund collection, investment and claim settlement, and often have higher management and operation costs

Sixth, the data stored on the public welfare field

blockchain is highly reliable and tamperable, which is naturally suitable for social public welfare scenarios. The relevant information in the public welfare process, such as donation project, collection details, fund flow, recipient feedback, etc., can be stored on the blockchain, and can be made transparent and public, which is convenient for social supervision

3. The origin of blockchain comes from "bitcoin: a peer-to-peer e-cash system" published by Nakamoto in 2008. According to this concept, the first proct "bitcoin" was born. The origin of blockchain technology is usually attributed only to the actions of some mysterious geniuses who work under the pseudonym of Nakamoto. This view of history often makes the technology seem almost magical and difficult to understand. When people understand the actual history behind the development of these systems, it is more fundamental. In this section, I will outline the most important topics in decades of research on consensus algorithms and distributed systems that led to the creation of blockchains.

4. How to reach a consensus on decentralized networks
in the blockchain system, there is no centralized bookkeeping institution like a bank, so it is very important to ensure the consistency of each transaction on all bookkeeping nodes, that is, to make the whole network reach a consensus. The consensus mechanism solves this problem
at present, the main consensus mechanisms are workload proof mechanism POW and equity proof mechanism POS
POW determines your chances of getting bookkeeping rights by evaluating your workload. The greater the workload, the more likely you will get this bookkeeping opportunity
POS determines your chances of getting bookkeeping rights by evaluating the number and ration of tokens you hold. This is similar to the stock dividend system, holding a relatively large number of shares can get more dividends
the principle of dpos is similar to that of POS, except that some "deputies to the National People's Congress" are selected. The main difference from POS is that the node elects several agents, which are verified and recorded by the agents
with the development of technology, more advanced consensus mechanisms may emerge in the future.

5. The solutions are as follows:
1. Regularly clean the st in the computer, turn off the computer, open the chassis, use a hair dryer and blow with cold air< At ordinary times, 360 guard, Jinshan guard and other tools should be used to clean up the system garbage and temporary files generated by the Internet, and check and kill malicious

Italian software
3. The computer configuration is poor, so try to set the virtual memory as large as possible, and install anti-virus software with less resources, such as NOD32, or only one

auxiliary anti-virus software
4. Try to set the IP to static IP, which can rece the startup time of the computer
5. Don't put too many files and icons on the computer desktop, which will slow down the reaction of the computer. Try not to install the software on disk C
6. Regularly defragment the disk. Open the drive of my computer to defragment - properties - tools

select the disk to be defragmented. Open the "disk defragmenter" window - Analysis - defragmentation - the system will start to defragment

6. I've also used some voting software, but I didn't see the technology used in the software. It's very good to see the introction upstairs. I'll go to know something about blockchain later.

7.

The first real milestone should be a local election, and the ultimate goal is a national election

At a time when people's trust in government agencies in western countries is declining at an alarming rate, the Russian government under Putin is taking measures to strengthen people's trust in its system

Russia's democratic system has a long history, but the corruption left by the collapse of the Soviet Union and the plunder by the western world in Yeltsin's reign are still a big problem

Russia's launch of this system coincides with the time when "us special prosecutor Mueller formally filed a lawsuit against 13 Russians and three Russian entities for interfering in the 2016 US presidential election, causing a global sensation". For the anti democratic forces, the incident makes Mueller look more like an available fool

while Washington's bigwigs are still dissatisfied and complaining about the election results they don't like, Russia is taking action to ensure that one of Joseph Stalin's most frequently quoted maxims - "the voter decides nothing, the teller decides everything" does not apply to Russia

8. Blockchain practitioners have come to answer this question. We are familiar with financial, medical and ecation instries. However, in terms of social management, there are already leading blockchain technology companies in China that can bring new changes,
such as wangchain technology, which can achieve new effects in proxy voting, identity authentication, file management, justice, inheritance, personal social credit, and business administration.
