ICBC's blockchain for public welfare

1. Hello, cbyea500, the top in APM series< But as an open source flight control system, it can also be programmed by itself
performance is certainly enough for general flight control. In fact, performance is also related to your ability to write algorithms

for details, you can go to the relevant forums and ask< BTW: are you Michael Dou Bi?

2. Try changing a computer, a USB interface, and a data cable.
I know so much. I hope I can help you. If I can't, I can only try changing an MP3

3. Let's not talk about the advantages of blockchain public welfare. Just imagine how public welfare and charity organizations manage donations without a good supervision mechanism. Many people's first reaction should be that donations can't be traced and information is not transparent
blockchain technology + public welfare does not need third-party supervision, which reces the management cost. Secondly, donations can be managed by directly recording transaction data in the blockchain. Zhongan's firepile public welfare with blockchain technology is in this form
I can't be sure, but I have solved those uncertain problems before.

4. We are very concerned about the current situation and are willing to donate materials, but we are worried that someone will tamper with the distribution of materials, but once on the chain, everything can not be changed, open and transparent, recently
Changsha high tech Zone
launched the SMIC
blockchain
project, and the blockchain is still very popular recently.

5. Tencent is the first to lead the blockchain in security, recording the whole process of donation material demand, supply, transportation and many other links on the chain for certificate storage, ensuring safety and compliance, and supporting the 100 million level business data on the chain efficiently.

6. Open and transparent information and traceability of funds have always been the goals of public welfare and charity. Blockchain can do just that. It can not only track and record all the information, but also ensure that the information is traceable and authentic. As for the successful cases, it seems that there are not many now. After all, it is an emerging technology, and it will certainly get strong support and application in the future.

7. Charity is a big topic. Here is a detailed introction of blockchain technology and how to help people in difficult areas to receive better help
whether it's the government or the public welfare organizations, charity is particularly important for people in difficult areas. However, we often think about whether the relevant funds have been allocated to people and where the money has been spent?, Where is the money spent? All these problems are worthy of our consideration
blockchain technology can give charity related funds & quot; Traceability & quot; Develop a charity based app to Digitally encrypt every charity fund or related materials (using the internationally recognized sha256 or China's encryption algorithm SN2)
the data structure of funds and materials uses Merkle tree to store the material data, ensuring that any changed data will automatically become invalid
the applicant and issuer who use asymmetric digital signature, The verifier and the secret key management of "public key" and "private key" can effectively record the processing data of a payment. If the payment is improperly processed or someone wants to query it, it will be very clear.

8. Yes, the Tencent security leading blockchain of Tencent is very good. The whole process of donation business is open, transparent and traceable.

In recent years, financial fraud, accountant audit failure and other risk events occur from time to time in the capital market, which brings legal risk and reputation risk to commercial banks, and has attracted the attention of the leaders of the State Council

on December 18, the "bank letter blockchain service platform" was officially released, which was launched by China Banking Association and China Institute of certified public accountants to actively implement the document requirements of the notice on further standardizing the work of bank letter and reply letter, study and promote the digital construction of letter, and improve the standardization level of letter business

"we hope that the future bank letter blockchain service platform can play a role in preventing and resolving risks, promote the improvement of letter quality and efficiency, strive to build a demonstration digital platform with high security, strong public welfare, convenience and efficiency, and make e contributions to improving the construction of social credit system and strengthening financial services for the real economy." Liu Fushou, chief lawyer of CIRC, said at the press conference

Pan Guangwei, full-time vice president of China Banking Association, said that in the future, China Banking Association will work with relevant institutions to promote the transformation and upgrading of letter business towards the direction of intensive operation and management, electronic path, standardized business process and refined data governance, improve the quality of accounting information and audit, promote the construction of social credit system and help the high-quality development of banking instry

three core advantages

bank letter and reply are the process in which the certified public accountant, after obtaining the authorization of the audited unit, directly sends the confirmation letter to the banking financial institutions, inquires about the authenticity of the audited unit's bank deposit, bank loan, guarantee, financial management and other information, and the bank inquires, checks the relevant information and provides the reply

According to pan Guangwei, letter confirmation is one of the core proceres of independent audit, which is crucial to identify errors and frauds in financial statements. For the whole financial market, letter work is related to the quality and efficiency of audit work, the quality of accounting information and the authenticity of capital market data, which is very important to prevent financial risks

"the bank letter blockchain service platform adheres to the construction concept of authority, fairness and public welfare, follows the principles of marketization, openness and graalness, and graally promotes the transformation and development of bank letter to the direction of intensification, electronization, standardization and refinement, with three core advantages." Pan Guangwei said

one is platform target location. The platform has changed the offline decentralized letter reply mode to online centralized processing, which can complete the whole process of bank letter application, authorization, sending and reply online, speed up the letter processing efficiency, effectively solve various disadvantages of traditional paper letter mode, rece the degree of manual intervention of accounting firms, banks, audited units and other related parties, and enhance risk control, Rece the risk of data error and fraud

Second, in terms of platform security. The platform only retains the information of the letter transmission process, not the letter data information, and pays attention to the information isolation and confidentiality, so as to ensure the data security of banks and offices. The platform has a financial level security protection environment, which can realize 7 * 24-hour system safe operation

The third is the platform technical support. The platform chooses "ICBC Xi chain" as the underlying blockchain technology. ICBC Xi chain not only has significant technical advantages, but also has completely independent intellectual property rights. It has passed the authoritative certification of trusted blockchain of MIIT, and has many mature application projects

100 banks have applied for access

at the press conference, pan Guangwei also said that after confirming that the bank letter platform takes blockchain as the underlying technology, the working group has carried out on-site communication with a number of technology companies with blockchain technology and scene application one by one. After experts' evaluation, the blockchain technology is selected to be independent and controllable, safe and reliable, and the business connection and scene application are improved ICBC technology, which has more advantages in later operation and maintenance, is the project contractor

it is understood that as the underlying blockchain technology, "ICBC Xi chain" participated in the trusted blockchain evaluation of China Academy of information technology in 2019 and 2020, and passed five technical evaluations of function, baas, performance, security and password with 100% passing rate. It is the first blockchain proct in the financial instry to be certified by an official authoritative evaluation institution

"with the strong support of instrial and Commercial Bank of China and instrial and Commercial Bank of China technology, the system development work was officially completed on October 26, and joint debugging and testing work was being carried out with a number of banks and accounting firms. At present, 100 banks and dozens of accounting firms have clearly signed up to apply for access to the platform. We will actively connect with banks and accounting firms to be connected to the platform, and provide solutions and training according to the needs of all parties. " Pan Guangwei said

Zhang Wenwu, vice president of ICBC, said at the press conference that ICBC has always paid attention to the quality of bank letter work, and ICBC technology company has further innovated and improved on the basis of ICBC's original letter e-letter, spared no effort in platform construction, and realized the platform's proction and online on schele“ The signing of the cooperation agreement will be taken as an opportunity for the first batch of banks to actively cooperate with the construction of the platform, promote the interconnection between e-letter and the platform, and fully support the use of the platform through the practice of centralized letter and certificate at the bank end. "

At the press conference, Liu Fushou also said that it is necessary to promote the construction of the letter certification platform in a safe and orderly manner, adhere to the principle of safety, prudence and risk control, adhere to the principle of pilot first and steady progress, and adhere to dynamic adjustment and continuous improvement

For LAN environment, in order to ensure that each computer can access the Internet smoothly, limiting the network speed of each computer is the best way. Today, I will take Lingke router as an example to introce how to limit the traffic

log in to Lingke router, click system in the left navigation - click IP flow control option, where you can enter a section of IP address to limit the uplink and downlink bandwidth, and then click Save to save it

1. Click to list the IP speed being used

after clicking, you can view the current internal IP's external network uplink and downlink traffic and WAN port traffic, which can be arranged according to IP and speed to effectively view the network situation

2. Start IP and end IP

this is to select the intranet IP segment or single IP you want to limit. If only a single IP is limited, just fill in: 192.168.1.100 to 100, then this rule is to control 192.168.1.100. If you want to limit a group of IP ranges, fill in 192.168.1.100 to 150, so this rule is to limit 192.168.1.100 to 150. If this bandwidth limit is for all IP in the intranet, fill in 192.168.1.0 to 0, which means that all IP are restricted by this rule

3. Uplink bandwidth www.2cto.com

refers to the upload bandwidth of Intranet IP

Fourth, downlink bandwidth refers to the download bandwidth of Intranet IP, where the rate is kbit / s, the general file download rate is KB / s, 1KB = 8kbit

v. flow control threshold value

this threshold value refers to the set threshold value of WAN port bandwidth. When flow control is enabled, if it is not set or set to 0, it means that flow control is always enabled. Otherwise, it means that when the total utilization rate of WAN port is greater than the threshold value, flow control will actually take effect. After the flow control takes effect, the system will execute the flow control for 5 minutes regardless of whether the flow reaches the threshold. After 5 minutes, the system will detect the WAN port utilization again. If it is lower than the threshold, the flow control will not be enabled. If it is higher than the threshold, the flow control will be enabled again

note: this function is only used when the maximum bandwidth is limited, and it needs to enable queue management and set WAN port bandwidth

6. Automatic load balancing

If multiple adsls of the same operator are used, automatic load balancing can be selected, and static routing table is not needed in WAN port configuration. Traffic will automatically use multiple Wan ports to transfer data, so that data can be evenly transmitted from multiple Wan ports

7. Line backup mode when this function is enabled, wan1 is used as the main line and other lines are not online. When wan1 is disconnected, other lines will go online. If wan1 goes online again, other lines will go offline again

8. Start queue management

when you choose to limit the minimum bandwidth, starting queue management will rece the system performance. If you need to ensure the minimum bandwidth, start queue management, accurately set the WAN port bandwidth, configure the uplink and downlink value of the minimum bandwidth, and then restart the device to achieve the maximum speed of each computer; www.2cto.com 9. Wan line speed setting is the same as WAN port configuration

X. flow control mode

(1) guarantee the minimum bandwidth

as the name suggests, guarantee the minimum bandwidth that each computer can use

(2) limit maximum bandwidth

to limit the maximum available bandwidth of this rule, that is, the maximum bandwidth will not exceed this set value

the above is the flow limit setting of Lingke router, I hope it can help you
