1. What does the number of people in the Ethereum contract mean? I know the top speed.
2. At the top of Ethereum is DAPP. It exchanges with the smart contract layer through Web3. JS. All smart contracts run on EVM (Ethereum virtual machine) and use RPC calls. Below EVM and RPC are the four core contents of Ethereum, including: blockchain, consensus algorithm, mining and network layer. Except DAPP, all other parts are in the Ethereum client. The most popular Ethereum client is geth (go Ethereum)
3. There is no such word, only longicorn, which means longicorn
Cerambycidae is the general name of Cerambycidae in Coleoptera, with chewing mouthparts, long antennae, often longer than the length of the body. There are more than 20000 species in the world. Some species belong to pests, whose larvae live in wood and may cause damage to trees or buildings
longicorn is a kind of herbivorous insects, which can harm woody plants, such as pine, cypress, willow, elm, walnut, orange, apple, peach and tea, some cotton, wheat, corn, sorghum, sugarcane and hemp, and a few wood, buildings, houses and furniture. It is the main pest in forestry proction, cultivation and construction wood
there are about 40000 species of Cerambycidae beetles in Coleoptera. Their common English names are derived from the very long antennae of most species. It is distributed all over the world, but most in the tropics. The length is 0.4-18cm, but if the antennae are included, the length can be increased by 2-3 times. Many alts (e.g. clytus arietes) collect pollen. They are yellow, black and orange, and resemble wasps; Some tropical species of the genus clytus are ant like; The African beetle (pterognatha gigas) is like a piece of moss or lichen with several lines (protruding antennae)
the larva of longicorn beetle is light yellow or white, and the alt of longicorn beetle has a long cylindrical shape. The front end expands into a round shape and looks like a head, so it is commonly known as the round head borer. It has a strong palate and can live in trees for more than two years, destroying wood. Before pupation, a hole is drilled outward to pupate in the tree, through which newly emerged alts emerge. Three pairs of feet, two pairs of wings. Because of this habit, longicorn damages wood and pulp trees, landscape trees, fruit trees and woody ornamental plants
the alt is a long cylinder with a slightly flat back; The antennae are attached to the protuberance of the forehead (called antennal basal tumor), which can make the antennae rotate freely and cover the back of the insect. Claws are usually single tooth type, a few are attached teeth type. Except for Cerambycidae, the midthoracic plate often has a articulator. Larva body is thick and fat, oblong, slightly flat, a few slender. The head is broad or oblong, and often retracts into the anterior sternum
longicorn is known as longicorn because it is as powerful as an ox and is good at flying in the sky; And because it makes a sound of "click, click", its sound is very similar to the sound of sawing trees, so it is also called "sawing tree Lang". In addition, some areas in southern China are called "shuiguniu" and "Shuiniu", while some areas in northern China are called "chunniuer". Species and distribution the size of this insect varies greatly from species to species. The largest one has a body length of 11cm, while the smaller one has a body length of only 0.4-0.5cm. The most special feature of this insect is that its antennae are extremely long. In North China, there is a species called Cerambycidae longicornis, whose antennae length can reach 4-5 times of its own body length. In common Cerambycidae, its antennae can also reach about 10cm. Another feature is its powerful jaw. Species and distribution: the body color of longicorn is mostly black with metallic luster. Its alts are common in forest areas, gardens, orchards and other places. When flying, its Coleoptera are open and motionless, and its inner wings fan to make a "whining" sound. Most of them occurred in 1 generations in 1 years, and in 3 or 2 or 2 years, which are pests that damage trees such as poplar, willow, mulberry, Sophora japonica, Wutong and Melia.
longicorn is a well-known insect. Many people caught or observed longicorn in their childhood and became interested in them. Interestingly, when you grab it, it makes a "creak" sound, trying to escape. If you tie a thin thread on its leg and let it fly, you can still hear the sound of "camp". There are many ways to play longicorn, such as racing, pulling cars, fishing and barking. Compared with the electric toys that are full of the market, playing this kind of "natural pet" is much more interesting. But I want to remind you that when you play, be careful not to be bitten by the strong upper jaw of Longhorn
the vowel o makes short vowels in stressed closed syllables/ ɑ/ When pronouncing, the tip of the tongue is close to the lower teeth, the back of the tongue is raised, the gums are nearly fully open, the mouth is large, and the lips are round. This sound appears at the beginning, middle and end of the word, such as:
ox bull (castrated)
October
Octopus

top ten Ethereum mining software in 2020
in terms of market value, Ethereum is the second largest cryptocurrency, second only to bitcoin. Ethereum's popularity among the holders has increased rapidly because it can build the whole decentralized ecosystem and applications on top of its blockchain. As Ethereum is friendly to GPU mining, Ethereum is a good choice for PC users (especially those with AMD high-end graphics cards). However, 24ker should also warn readers that at this time point, Ethereum's price is $241, which means that even if you use radon VII (90mh / s), your weekly profit is less than $7, The annual profit is about $339. However, considering the potential value-added space of Ethereum, if the price can return to the healthy range of $500-600, it means that your radon will be back in one year
if you already have Ethereum mining hardware and an effective wallet, all you have to do is to find the best eth mining software, which will help you manage the mining work effectively
in this article, we will introce the features, advantages and compatible operating systems. But before we get there... Let's talk about the basics
why Ethereum
unlike traditional currencies, Ethernet operates on the public ledger system, which makes mining itself the core power of Ethereum network. When miners receive the transaction data sent by other members of the network, they assemble them into a structure called Merkle tree, and then try to find an acceptable hash value
only one hash will be returned for each dataset, and the hash value cannot be used to dece the original data. Its purpose is to effectively ensure that the block information is not tampered with. Moreover, if someone changes even one number in any long transaction string, the output hash value will be completely different, and false transaction or fraud will be eliminated
as you can see, if there is no Ethereum mining, Ethereum network will be paralyzed immediately. Therefore, participating in Ethereum mining is not only the mining revenue, but also the support for the operation and growth of Ethereum
what is mining software< In short, mining software is a program that uses a computer graphics card (GPU) as a resource to solve complex mathematical equations. Once the equation is solved, the data is added to the rest of the blockchain
the mining software will monitor the input and output of the hardware, and display statistical data to you, such as miner speed, fan speed, temperature and hash rate
the Ethereum mining software described in this article can be connected to many available Ethereum mining pools
Ethereum mine pool
Ethereum mine pool is a resource area that is equally distributed and shared among miners. Nowadays, it has become too difficult for a person to dig a mine, so it is necessary to use the way of mining pool to fight in groups
today, Ethereum is one of the most famous choice of Ethereum mines. The pool allows its users to remain anonymous and pay only a small 1% mining fee<
top ten Ethereum mining software:
1-ethminer (Ethereum Royal)
it can be seen from the name that ethminer is specially designed for mining Ethereum, and currently supports Linux, MAC and windows. Make sure to download the version corresponding to the device's operating system
in addition to Ethereum, you can also use ethminer to mine all tokens according to ethash algorithm, including expand, elaism, metaverse, musicoin, Pirl, Ethereum classic, etc< Ethminer is a command line software. This means that you can start it from the Linux console or the windows command prompt, or you can use the windows CMD / batch file or the Linux bash script to create a shortcut to the preset command line<
(2-cgminer)
this program was released in 2011. Because it is compatible with three different mining hardware (ASIC, FPGA and GPU), it is still one of the most popular mining software options. CG miner is an open source Ethereum miner written in C language, and provides support and binary files for openwrt router, RPI, etc
the advantages of cgminer include the ability to match your hash rate with zero latency extension, remote interface function and advanced detection of new blocks. The software can be used for Mac, Linux and windows
3 - Claymore (maximum efficiency)
if you are looking for the most efficient Ethereum mining software, please consider using Claymore's al Ethereum mining machine, which can speed up to any hash rate without sacrificing the mining speed
Claymore recently released v12.0 upgrade, which reces the equipment cost of al mining mode from 2% to 1%. The upgrade also offers 3gb and 2GB cards with zero development costs. However, Claymore al miner can't run on Mac. At present, it can only run on Linux and windows. But it supports both NVIDIA and AMD cards
other coins you can mine with this program include siacoin, lbry, decred and Pascal< If you are not familiar with cryptocurrency mining and are looking for the simplest Ethereum mining software, please check wineth
the software is based on the ethminer that we have just evaluated, but wineth provides users with a more simple and easy to understand GUI, combined with "intelligent" algorithm, which will provide the configuration that can ensure the best performance on the new user's hardware
as can be seen from the name, wineth is only compatible with windows devices, and you can find it in the windows 10 app store.

6. Defrauding 50000 yuan is a "huge amount" and should be sentenced to fixed-term imprisonment of not less than three years but not more than 10 years and a fine. The amount of 50000 yuan should be sentenced to four to five years' imprisonment, that is, the principal offender in this case can be sentenced to four to five years' imprisonment under normal circumstances. Returning personal stolen money can be given a lighter punishment on the basis of the above
if he is an accomplice, he can be given a lighter or mitigated punishment. Therefore, if he is an accomplice and returns the stolen money, he can be sentenced to three years' imprisonment and probation< Article 266 of the criminal law of the people's Republic of China whoever swindles public or private property, if the amount involved is relatively large, shall be sentenced to fixed-term imprisonment of not more than three years, criminal detention or public surveillance and shall also, or shall only, be fined; If the amount is huge or if there are other serious circumstances, he shall be sentenced to fixed-term imprisonment of not less than three years but not more than 10 years and shall also be fined; If the amount is especially huge or if there are other especially serious circumstances, he shall be sentenced to fixed-term imprisonment of not less than 10 years or life imprisonment and shall also be fined or have his property confiscated. Where there are other provisions in this law, such provisions shall prevail<

Generally speaking, Merkel tree is a way to hash a large number of "chunks" of data. It depends on splitting these data "chunks" into data chunks with smaller units (buckets). Each bucket block contains only a few data "chunks", and then takes each bucket unit data chunk for hashing again to repeat the same process, Until the remaining total number of hashes is only 1: root hash
the most common and simplest form of Merkel tree is binary mekle tree, in which the data block of a bucket unit always contains two adjacent blocks or hashes. Its description is as follows:
decent, bitcoin and Ethereum smart contract are all this structure
9. Reference answer 4. As long as there are leaves flying, there will be fire burning, the fire will shine on the village, and then new leaves will sprout again———— Three generations of Huoying (before death)-
10. Merkle trees are the basic components of blockchain. Theoretically speaking, it is possible to build a blockchain without a Merkel tree. You only need to create a huge block header that directly contains every transaction. However, this will undoubtedly bring scalability challenges. In the long run, only the most powerful computers will be available, To run these untrusted blockchains. It is because of the Merkel tree that Ethereum nodes can be built and run on all computers, laptops, smart phones, and even those IOT devices proced by slock.it. So, how do Merkel trees work, and what value can they provide, now and in the future< First of all, let's talk about some basic knowledge. Generally speaking, Merkel tree is a way to hash a large number of "chunks" of data. It depends on splitting these data "chunks" into data chunks with smaller units (buckets). Each bucket block contains only a few data "chunks", and then takes each bucket unit data chunk for hashing again to repeat the same process, Until the remaining total number of hashes is only 1: root hash.
