区块链技术在公安工作中的应用,区块链技术能否为公安工作提供技术支持

随着社会的发展，公安工作的重要性也日趋凸显，而区块链技术的出现也为公安工作提供了技术支持。下面就来介绍一下区块链技术在公安工作中的应用，以及如何为公安工作提供技术支持。

一、数据存储

区块链技术可以有效地帮助公安机关存储大量的数据，其中包括案件信息、警务信息等等。区块链技术的一大特点就是去中心化，也就是说，数据存储在多个节点之间，而不是一个中心节点，这样可以有效防止数据被篡改、丢失或者被盗取。此外，区块链技术还可以支持数据的安全共享，可以有效地保护公安机关的数据安全。

二、智能合约

智能合约是区块链技术的一个重要组成部分，它可以有效地帮助公安机关管理合同，比如把合同内容写入智能合约中，当合同条件被满足时，智能合约就会自动执行，从而有效地降低了合同管理的成本。此外，智能合约还可以用于监督警察的行为，以确保警察的行为符合法律法规，从而保证公安机关的职业操守。

三、身份认证

通过区块链技术，公安机关可以更有效地进行身份认证，比如可以建立一个全国范围的身份认证系统，以便更好地管理公民的身份信息，并可以有效防止身份盗用。此外，区块链技术还可以用于管理警务人员的身份信息，以确保警务人员的身份真实性，从而保证公安机关的职业操守。

以上就是区块链技术在公安工作中的应用，以及如何为公安工作提供技术支持的介绍。区块链技术的出现，为公安工作提供了技术支持，可以有效提高公安机关的工作效率，保护公民的身份信息安全，确保警务人员的职业操守，为公安工作提供了技术支持。

I. What is the progress of the Wuxi Blockchain Liang Liang case?

On January 21, 2020, the official WeChat of the Xishan Branch of the Wuxi Public Security Bureau issued a notice saying, “On the afternoon of January 10 , the Xishan Branch of the Wuxi Municipal Public Security Bureau arrested the suspect Liang Mouliang on suspicion of illegal business crimes in accordance with the law. Liang Mouliang has been criminally detained, and the case is under further investigation." This report attracted attention in the industry. Who is Liang Mouliang? ?What does his illegal business crime refer to? What projects are involved?
It is reported that Liang Mouliang is from Wuxi, Jiangsu Province. He studied in Germany and Switzerland and later returned to China to start a business. He established Wuxi Ai in 2017Chain Technology Co., Ltd. is committed to the promotion and application of blockchain technology. He is also one of the founders of the Blockchain Technology Innovation Alliance (Wuxi), which is managed by the Wuxi Municipal Government and aims to establish a Wuxi blockchain industry ecosystem.
Liang Mouliang’s illegal business crime refers to the “Love Chain” project he established in Wuxi City, which is suspected of illegally absorbing public deposits. At the end of 2018, "Love Chain" announced that it would launch the "Love Chain" wallet based on blockchain technology globally, which can be used in many fields such as digital currency transactions and online shopping. Liang Mouliang once publicly stated that the "Love Chain" project attracted 2 billion yuan in funds in less than 2 months, and there were thousands of agents promoting the development of the project.
But as time went by, the progress of the "Love Chain" project was not as Liang Mouliang said. The project progressed slowly and even involved debt disputes. It is reported that as of June 2019, the "Love Chain" project has only completed part of the development work and has not yet been launched. The 2 billion yuan in funds claimed by Liang Mouliang has not been confirmed. Previously, some media reported that the “Love Chain” project was suspected of illegal fund-raising and posed huge risks.
Not only that, the "Love Chain" project is not the only field Liang Mouliang is involved in. He has also participated in many projects such as "Fall in Love with Tesco" and "Fall in Love with Insurance", which attracted a large amount of investment. However, these projects have not been completed as scheduled, and the financial disputes involved are also increasing.
Faced with many problems, Liang Mouliang did not take active measures to solve them. Instead, he insisted on publishing false propaganda to attract more investors. This also attracted the attention of the public security organs. At present, Liang Mouliang has been criminally detained, and the case is under further investigation.
In general, the progress of Liang Mouliang’s case shows the Chinese government’s zero-tolerance attitude towards illegal fund-raising and fraud. Regarding the promotion and application of blockchain technology, the government will also strengthen supervision to prevent risks and ensure national financial security. For the blockchain industry, it needs to be more standardized and compliant to avoid risks and problems similar to the "Love Chain" project.

J. The police cracked the country’s first casino case using blockchain contract technology, and how many suspects were arrested

On April 15, “Yancheng Jianhu Public Security Micro-Police” WeChat The official account reported that Jianhu police recently successfully cracked the country's first case of using blockchain contract technology to open a casino, arrested 25 suspects, and seized more than 1.3 million virtual coins worth more than 26 million yuan involved.

(10) Extended reading on public security law enforcement using blockchain technology

In recent years, fraud cases involving “blockchain” have frequently appeared online: < /p>

The Cyber ​​Security Bureau of the Ministry of Public Security also reported a week ago that in January 2021, the Public Security Bureau of Gaoxian County, Yibin City, Sichuan Province uncovered a gang that issued false digital currencies to commit fraud, arrested 9 suspects, and detained those involved in the case. There were 3 computers and 11 mobile phones, and more than 10 million yuan of funds involved in the case were frozen.

Because this type of fraud uses the banner of "blockchain", the packaging is very high-end. For example, in the Yibin case, criminal gangs posted advertisements in hotels and other places, promoting the concepts of "poverty alleviation" and "One Belt, One Road", and used false propaganda to deceive investors into believing that this project was endorsed by national policies, inducing those who did not know what was going on. Investors fell headlong into the trap. The criminal gang even rented an entire floor in a certain district of Chengdu to use as an office, which is quite a big deal.

There seems to be no upper limit to the facade, but the criminal gang’s operating methods have no lower limit. They promote it through two models: online APP trading + offline agency. The transaction price and ups and downs of the "fake digital currency" they issue are completely set and modified by the organizers themselves, and there is no support from implemented projects at all.
