Obstacles to the combination of blockchain and 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.

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
