EH bitcoin
bitcoin uses SHA-256 encryption algorithm. When mining, it competes with computing power. In order to improve computing power, bitcoin has gone through four stages: CPU mining, GPU mining, FPGA mining and now ASIC mining machine mining, and the degree of specialization is getting higher and higher
Ethereum uses the ethash encryption algorithm. In the process of mining, it needs to read the memory and store the DAG file. Because the bandwidth of each read memory is limited, and the existing computer technology is difficult to have a qualitative breakthrough in this problem, so no matter how to improve the computing efficiency of the computer, the memory read efficiency will not be greatly improved. Therefore, in a sense, Ethereum's ethash encryption algorithm is ASIC resistant.
different encryption algorithms lead to great differences in mining equipment and computing power between bitcoin and Ethereum
at present, bitcoin mining equipment is mainly ASIC mining machine with a very high degree of specialization. The maximum computing power of a single mining machine is 110t / s, and the scale of computing power of the whole network is more than 120eh / s
the main mining equipment of Ethereum is video card miner, and there are very few specialized ASIC miner. On the one hand, the "ASIC resistance" of Ethereum mining algorithm improves the threshold of developing ASIC miner. On the other hand, after Ethereum is upgraded to 2.0, the consensus mechanism will be transformed into POS, and the miner can not continue mining
compared with the ASIC miner, the graphics card miner has two orders of magnitude difference in computing power. At present, the computing power of mainstream graphics card miner (8 cards) is about 420mh / s, and that of Ethereum is about 230th / s.
from the time dimension of the past two years, bitcoin's computing power of the whole network is growing rapidly, while Ethereum's computing power of the whole network is growing relatively slowly
The ASIC mining machine of 
bitcoin is monopolized by several major mining machine manufacturers, and miners can only buy it from the market; Although the graphics card miner of Ethereum is also manufactured by a special miner, the miner can buy accessories from the market and assemble them according to his own demand
Bitcoin is just like the currency in the game, but no one releases bitcoin. Instead, it relies on a specific algorithm to generate , so now people looking for bitcoin also call themselves miners, but they rely on computers to mine
the rise of bitcoin is e to the restructuring of global risk assets , and the widening of investment channels for encrypted assets . Since the beginning of this year, the volatility of securities and foreign exchange markets has intensified, and global investors are looking for safe assets. Traditional safe asset gold is more dependent on the real economy and inflation expectations, Bitcoin is more like a sensitive index, gaining a certain asset hedging advantage
No illegal
in the bitcoin risk notice jointly issued by the people's Bank of China and other five ministries and commissions at the end of 2013, bitcoin is clearly defined as a special Internet commodity, and people can buy and sell it freely at their own risk. But it denies the monetary nature of bitcoin< The Article 143 of the general provisions of the civil law stipulates that "the civil legal act with the following conditions is valid:
(1) the actor has the corresponding capacity for civil conct< (2) the expression of intention is true< (3) it does not violate the mandatory provisions of laws and administrative regulations, public order and good customs. " The announcement of the seven ministries and commissions is neither a law nor an administrative regulation, and can not be used as a legal basis for judging whether a civil juristic act is valid or not; The law does not go back to the past. Therefore, the bitcoin transaction has legal effect, and the bitcoin obtained from the transaction is protected by law. Therefore, legal disputes arising from trading activities, including civil or criminal cases, should be subject to jurisdiction. Courts or public security organs can not refuse to accept bitcoin because they think bitcoin is not protected by law

transaction mode
bitcoin is e-cash similar to e-mail, and both parties need "bitcoin wallet" similar to e-mail and "bitcoin address" similar to e-mail address. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address. The following table lists some websites that download bitcoin wallets and addresses for free
a bitcoin address is a string of about 33 characters long, consisting of letters and numbers, always starting with 1 or 3, such as & quot& quot; Bitcoin software can generate address automatically, and it does not need to exchange information online when generating address, so it can be offline [2]. More than 2 bitcoin addresses are available. Figuratively speaking, there are about two grains of sand in the world. If there is an earth in each grain of sand, then the total number of bitcoin addresses far exceeds the number of all the sand on all these "earths"
the bitcoin address and private key appear in pairs, and their relationship is just like the bank card number and password. A bitcoin address is like a bank card number, which records how much bitcoin you have on it. You can generate bitcoin address at will to store bitcoin. When each bitcoin address is generated, a corresponding private key of the address will be generated. This private key proves that you have ownership of the bitcoin at that address. We can simply understand the bitcoin address as the bank card number, and the private key of the address as the password of the corresponding bank card number. Only when you know the bank password can you use the money on the bank card number. Therefore, please keep your address and private key when using bitcoin wallet
after the transaction data of bitcoin is packaged into a "data block" or "block", the transaction is initially confirmed. When a block is linked to a previous block, the transaction is further confirmed. After six block confirmations in a row, the transaction was irreversibly confirmed. Bitcoin P2P stores all transaction history in a "blockchain.". The blockchain continues to extend, and once new blocks are added to the blockchain, they will not be removed. Blockchain is actually a distributed database composed of a group of scattered client nodes and all participants, which is a record of all bitcoin transaction history. Nakamoto predicts that when the amount of data increases, users hope that not all the data will be stored in their own nodes. In order to achieve this goal, he uses the hash function mechanism. In this way, the client will be able to automatically eliminate those parts that it will never use, such as some very early bitcoin transactions
previously, graphics cards were sold out because of the strong purchase of gold miners. The algorithm design of bitcoin is more and more difficult to dig. Therefore, the investment to dig the same bitcoin now is many times higher than a few years ago. Since the "mining" incident in Daqing Oilfield was exposed, the local police have counted the number. The average electricity cost of the mining machine seized is close to 500000 yuan in one month, and if it steals electricity, it is equivalent to making 500000 yuan in vain.
It's not against the law
The laws and administrative regulations in China do not prohibit the proction, holding and legal circulation of bitcoin, nor do they prohibit the sale of bitcoin mining machines2. The investment and transaction of "virtual currency" represented by bitcoin are on the rise. For this kind of virtual goods generated in the Internet environment after the development of Internet technology, there are policy and commercial risks in related transactions. However, under the premise of not violating the mandatory provisions of laws and administrative regulations, the contract signed by the parties is a valid contract
3. Bitcoin is generated by "miner" and "mining", and "miner" can be assumed by anyone in any place in the world. "Mining" is a process in which "miner" provides certain computer computing power according to the open source software provided by the designer, and obtains the special solution of the equation through complex mathematical operations, The miner who gets the special solution gets a certain amount of bitcoin reward
Because bitcoin is based on workload proof, it is related to computing power. To have computing power, we need to consume power, so its power consumption is very large. It is precisely because of such a large power consumption that the safe and stable operation of bitcoin system can be guaranteed
extended information:
according to the data of btc.com website, up to now, the computing power of the whole bitcoin network is about 51.65 eh / s, which is equivalent to 1.84 million bitcoin S15 (28T computing power, 1596w power) mining machines in operation, and the daily power consumption is about 69.92 million kwh. Divided by the current proction of 1800 bitcoins per day, excluding other costs, each bitcoin will consume 38800 kwh of electricity. "
from this point of view, although the current price of bitcoin is expensive, the cryptocurrency market website coinmarketcap.com shows that the current unit price is about $7900, but the cost of mining a bitcoin is not low at all

in terms of price, so far, BTC has rushed to around us $11720, with a 24-hour increase of more than 2%
so the question is: where will bitcoin go in the next week
here are five factors that may affect the BTC price trend in the coming week<
No.1 US macro level: election and stimulus plan
this week, the US is the absolute focus of the macro market. The US presidential election will soon usher in a decisive moment (November 3)<
analysts warn that if the Democratic Party (Biden) wins, the dollar will depreciate - and the long-term outlook for the dollar is already precarious. Goldman Sachs said last week that Trump's re-election was not enough to get the dollar out of danger
however, no matter what the election result is, professionals recommend buying gold as a hedge. However, in the view of others, bitcoin may bring more profits
however, e to the inverse correlation between BTC / USD and US dollar currency index (DXY), the strength of US dollar will still affect the price trend of bitcoin in the view of some bitcoin traders. Although this correlation has become less and less obvious in recent weeks, the sudden weakness of the US dollar is still likely to be a boon for bitcoin

at the same time, not only the election, but also what happened before is also a topic of interest. Specifically, a coronavirus stimulus plan was in place before polling day
if this happens, trillions of dollars of liquidity will increase the growing debt pile of the United States, and Americans will see additional benefits, such as an additional $1200 economic stimulus plan
No.2 Europe suggests more intervention
with the outbreak again, the European Central Bank (ECB) is considering further measures
European Central Bank President Christina; In an interview with Le Monde on Monday, Lagarde said the European Central Bank would use more financial instruments if necessary
the European Central Bank's coronavirus stimulus program has purchased a total of 1.5 trillion euros of assets
Lagarde said: "we haven't exhausted the options in our toolbox."
brexit is increasingly moving towards "no agreement" brexit, which makes the possibility of instability worse<
the fundamentals of No.3 bitcoin have reached a new high
recently, bitcoin has maintained a strong resilience in the face of various black swan events. Influenced by okex, BTC recently dropped below $11200, but recovered steadily soon. So far, it has exceeded $11600
on the technical level, the fundamentals of bitcoin also maintained a record strength this month
two days ago, the difficulty of the latest adjustment increased by 3.5% than expected
at the same time, the hashing rate also climbed to an all-time high on Monday. At the time of publication, the estimated computing power for mining is 146 exahashs (EH / s) per second
as often reported in the media, the popular theory is that the price follows the hash rate, because the long-term investment prospect of bitcoin is better than ever before<

No.4 analysts focus on the $12000 BTC price breakthrough
for the famous analyst Micha & # 235; For Lvan de Poppe, the key price conversion of bitcoin is becoming more and more reasonable
in his latest video update on Sunday, he stressed that the significant resistance level of weekly closing price below $12000 for several consecutive years will soon end<
Van de Pope believes that since the beginning of the bear market in early 2018, US $12000 has become the rejection point of the weekly chart, but the consolidation below can not last forever
he concluded: "we are likely to rebound to the range of US $16000 to US $17000, because this is the obvious level and the last obstacle for bitcoin to begin to break through the all-time high."
after this move, there will be another consolidation period, which may last longer than the current period
van der BOPP added that he advised viewers to work hard to accumulate bitcoin, even in the $16000 range

No.5 market sentiment: greed is back
with the graal strengthening of prices, investor sentiment is also changing: data show that investor sentiment is becoming more and more greedy. In the latest market data, the fear and greed index has returned to the "greedy" area, rising slightly from "neutral" in the past week
this indicates that bitcoin investors' emotional expectations will be bullish, but it should be noted that if the price rises too fast, "greed" will become "extreme greed". In this case, the possibility of index correction is greater.
on May 26 this year, the Central Bank of Lithuania invited IBM, Deloitte, etc. to conct a live roadshow on the outstanding graation project of lbchain, the financial technology supervision sandbox of the Central Bank of Lithuania. The probe exchange is one of the roadshows. In November last year, probe exchange became the only project of lbchain sandbox test with team members from China
different from the common cryptocurrency exchanges in the market, probe exchange is a compliant cross-border digital asset issuance and trading platform, which holds the EU compliant financial license and can be supervised by the regulatory authorities technically. The whole technology and supervision process of digital assets is very complex. What probe exchange needs to do is to simplify the whole process and realize automation, so that every company can manage the digital assets of issuing securities on the probe platform through the step-by-step operation process on the probe platform. The trading of the exchange runs on the fabric network of IBM super ledger. Users or investors only need to deposit legal currency into the system to receive Euro stable currency eurt, and then they can use eurt to buy and sell various securities digital assets on the probe
at the graation roadshow on May 26, the Lithuanian central bank evaluated the significance of the financial technology practice of the probe exchange to digital assets, especially in opening up Asian and European markets. On June 1, the probe exchange obtained the graation requirements of the Lithuanian central bank, and thus walked out of the sandbox and into the market
in less than two months, probe exchange has reached cooperation agreements with kangjia and shanque canteen, and has successively signed strategic cooperation agreements with other companies
shengshang international is a Singapore group company with many years of experience in blockchain, artificial intelligence and Internet of things technology services. This landing probe will be beneficial to the increase of the whole network computing power of shengshang international and provide better services for the chain reform of various instries. It will transform the business process and social organization governance mechanism of the existing instries. The goal is to transform the proction relations and improve the efficiency. The result is the reconstruction and reorganization of the business process. The process is the decentralization of the business system and the disintermediation of the business process, The premise and foundation of chain reform is the distribution and storage of data on the chain, that is, the change of data possession and data organization
shengshang international capitalizes the income of computing power on the chain. The expected return of this asset is estimated according to the bitcoin network computing power of 110eh / s and BTC price of 65000rmb, with a monthly return rate of 3% - 25%
it is worth noting that shengshang international is the first project introced by the Star Alliance Foundation and the Lithuanian probe after reaching a strategic cooperation agreement. On July 15, the Lithuanian government and the Star Alliance Foundation signed a cooperation agreement. According to the Star Alliance Foundation, 100 entity enterprises will be introced to the probe exchange in the future. Digital asset trading is stepping into the era of scale<
