Does Ethereum require network speed

1. This should not have too many requirements, generally not less than 4 megabytes

the founder of bitcoin, Tsung Nakamoto, left the bitcoin project in 2010 and became one of the most mysterious figures in the coin circle. Bitcoin is made by mining. Mining is a process of consuming computing resources to process transactions, ensuring network security and keeping everyone's information synchronized in the network. It can be understood as the data center of bitcoin. The difference lies in its completely decentralized design. Miners operate all over the world, and no one can control the network. This process is called "mining" because it is similar to gold panning, because it is also a temporary mechanism for issuing new bitcoin. However, unlike gold panning, bitcoin mining provides rewards for services that ensure the safe operation of payment networks. After the last bitcoin, mining is still necessary.

2. Advantages: 10 / 100Mbps wired Ethernet has the advantages of low cost, convenient construction and higher network speed than wireless network. The new Gigabit (10 / 100 / 1000Mbps) technology is lightning fast, but mainly for the enterprise environment
disadvantages: you need to pull the cable to the center to connect the switch or router. Expensive gigabit network cards and switches need expensive special cables
cost: 10 / 100Mbps network card, 15-25 US dollars per PC; Or gigabit network card, 90-110 US dollars per PC; 10 / 100Mbps switch, 35-75 US dollars; Or Gigabit switch, 100-200 dollars; Internet router / firewall, 50-75 dollars
wireless network (Wi Fi)
advantages: no cable through the wall or aisle; You can surf the Internet on the sofa or in the yard with a laptop
cost: higher than wired network. If you want to get the maximum safety factor and the farthest transmission distance, you need to consider many aspects when building. The evolving standards are confusing and incompatible; As the distance increases, the network speed will decrease. Cost: US $50-90 for 802.11b PC card (10Mbps), or US $70-100 for 802.11b/g PC card (54 Mbps); Additional wireless PCI card, each PC is 90-125 US dollars, or USB wireless network card, each PC is 50-90 US dollars; Single speed wireless router, 50-100 dollars, or two speed wireless router, 225-300 dollars
hybrid network
advantages: it has the advantages of convenient construction and low cost
disadvantages: different technologies bring difficulties to network construction
cost: see "standard wired Ethernet" and "Wi Fi" above
power line network
advantages: simple installation, network layout in the home power line
disadvantages: the network speed is slow (12mbps), the cost is relatively high, and the network cards provided by different manufacturers may not be compatible with each other.

3. Many people have misunderstandings about broadband network speed and mistakenly believe that the higher the network speed, the better. In general, 2m broadband can play CF, lol and other games smoothly, 2m broadband can watch online high-definition [480p] video and live broadcast without card, 3M broadband can watch online ultra clear [720p] video, and all online applications of 10m broadband can meet the requirements, but the broadband network speed is required to be continuous and stable, and never drop [no delay!], In the whole country, only Telecom and Unicom meet the conditions, there is no third kind of broadband! Because of the high delay of all other broadband networks in the country [dropping more than 0.01 second for many times, the network speed sometimes can't be reflected by network speed measurement] when the actual network speed exceeds 100m, we can't play CF, lol and other games, watch online video and live broadcast, and can only browse the web, watch movies and TV dramas while downloading, This is the difference between high-quality broadband [specifically refers to telecom and Unicom] and junk broadband [all other broadband in the country]. If you install 200m mobile [Tietong], great wall, radio and television and other broadband, you will frequently drop the line. It's better to install 2m Telecom or 2m Unicom broadband.

4. Can not be generalized, online games also pagination and small games, large-scale online games. Generally speaking, the video requires enough bandwidth, 2 megabytes of Telecom is OK, 4 megabytes is very cool. When you play online games, you don't see things like this. There are a lot of online games that require real-time speed and low network latency. Some large online games can be played well with one megabyte of Telecom, while some small page games can't be impacted if you don't have four megabytes, because when it comes to a new map, you need a fairly high network speed. If you have bandwidth, you have to respond immediately. You have to have high bandwidth and low latency, It's fun to play. In other words, if you want to watch a good movie and play a good game, you still need to be willing to pay a higher price, and install a better local net. The garbage net is not very easy to use. South Telecom and North Netcom are better. Due to the monopoly and cost problems between various networks, there are problems in interconnection and the effect is not good. It's better to use a big brand, who calls it the boss.

5. There is no requirement for network speed, only speed
the unit of network transmission rate is BPs, which means the number of bits per second. People will intuitively understand it as the number of bytes transmitted per second (each byte has 8 binary bits), which is wrong. This is related to the network speed displayed by the current speed measurement software. Now most speed measurement software uses B / s or K / s to express the network speed; B" Or "K & quot; Is the unit used to represent bytes. The network speed measured in bytes needs to be multiplied by 8 to be the network transmission rate. For example, if the network speed is 400k / s, it should be 400000 bytes per second. If the network transmission rate is multiplied by 8, it will be 3200000 binary bits, which is 3.2mb/s network transmission rate
based on the principle that one byte represents an English letter and two bytes represent a Chinese character, 400k / s can transmit 400000 English letters or 200000 Chinese characters. This unit is generally used to measure disk capacity or memory size
the unit of broadband is Mbps, which is the number of bits transmitted per second. Home broadband speed, provided by Internet service providers. You can understand the corresponding network speed through the relevant network speed package
network card supports 10m / 100M adaptive network speed. In other words, the network card will adapt to the network speed that the service provider can provide (of course, only in the range of 10-100m). Of course, service providers are currently affected by many factors, the biggest can only provide home terminal network speed more than 10 megabytes or tens of megabytes, in short, it will not reach 100 megabytes.

6. I think it depends on the platform. For example, the platform I used before has very high requirements for network speed. If it's high, it's high. Don't get stuck, old carton. It's delayed. I've been indifferent to customer service several times. Later, I changed the platform. Now I use gosling. My network speed is 10m, which can meet my needs for open classes. The phenomenon of stuck is very rare, once or twice, I always go to customer service when I come across places I don't know. The customer service attitude is very good. I don't say that I'm impatient because I ask too many questions. Now I like Gosling more and more.

7. The requirement is that 30KB / S is enough for stable Riad war

8. If the flow is not smooth, it depends on the delay of the game. Generally speaking, if the delay is less than 100ms, it's a small card. If the network speed is poor, if it's less than 50ms, it's not a card. If you play normally, it's less than 20ms, it's very smooth, and you have to fly at 6. In general, 8m broadband, that is, the network speed above 500K, if you use it alone, enough!

9. Domestic telecommunication departments, if the Internet access technology is ADSL or special line, can be considered as broadband services. When signing the agreement, the telecommunication service provider should specify the network access speed in the agreement (note that the unit of network access speed is MB / s, 1MB / S = 128KB / s, 2Mb / S = 256Kb / s, that is, the access speed is calculated according to several bits per second, while the download speed of the download software we usually use is calculated according to several bytes per second), If he can't reach the access speed, he has the right to sue him for service failure or even fraud and claim compensation.
