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

1. The price of BTC and eth you see on this platform is not the real price against the US dollar, but the price in usdt, which is priced in OTC legal currency. Their ups and downs are all calculated in terms of usdt. All three of them are virtual currencies, just currency transactions, not real dollar prices

2. Usdt is a complete domestic counterfeit currency, formerly known as realcoin, but it has just changed its name. Realcoin is the second generation of domestic counterfeit currency, and the first generation is called chncoin Chinese currency. Both of them collapsed successively in 2013 and 2014

3. The actual value of usdt can be said to be equal to 0. Teda Company, which issued usdt, stopped providing any services to American citizens, that is to say, Teda Company could not provide usdt to us dollar

extended information:

1. Fire coin is a safe and reliable bitcoin trading platform in China. It has won a round of ten million RMB capital investment from Zhenge fund, Dai Zhikang, Sequoia capital (shareholders of many world-famous companies such as apple and Alibaba). Fire coin implements strict risk control management and operates stably. As of the end of 2016, the accumulated turnover of fire currency reached 200 billion yuan

2. In the future, fire coin will mainly focus on overseas transactions. Founder Li Lin said in an open letter that he is currently carrying out five major businesses around the world, including fire coin global professional station, fire coin Korea, fire coin China, fire Coin Wallet and fire coin global dollar station. Among them, fire coin China focuses on blockchain technology R & D and application information, while fire coin Korea and fire coin global dollar station will continue to provide local legal currency to digital currency digital asset trading services

First enter the official website, find the corresponding currency in the recharge withdrawal, fill in the corresponding information, and then submit the withdrawal

Trading rules of bitcoin:

1. Trading time: 7 * 24 hours, all year round

2. Account opening: the account opening process is simple. You only need to register with niubitnet and complete the real name authentication to recharge RMB, and at least recharge RMB 100 to start the transaction

Transaction fee: 0.2% for each transaction

T + 0 trading mechanism: the stock is t + 1 trading, that is to say, the stock can be bought on the same day and sold on the next trading day. Bitcoin and other digital assets are t + 0 transactions, which can be bought and sold on the same day. And there is no limit on the number of transactions

5. No limit on the rise and fall: the stock has a limit on the rise and fall, while bitcoin and other digital asset transactions have no limit on the rise and fall, for example, bitcoin rose more than 20% in a single day on May 28

6. Trading unit: the minimum number of BTCs that can be bought / sold is 0.001 (about 17 yuan), and there is no buy / sell limit of at least one hand (100 shares)

There is no time limit for cash withdrawal: cash withdrawal at any time, high liquidity

The basic principle of transaction: price first, time first. When the commission price is the same, the Commission order with earlier registration time is better than that with later registration time

5. Ethereum mining software is an Ethereum market display and trading software. Ethereum mining software can recharge and withdraw cash at any time without time limit. Ethereum mining software has the latest and complete market information. Ethereum mining software adopts advanced technology to ensure the safe, fast and stable trading. Using Ethereum mining software can provide you with professional, fast and convenient bitcoin / lightcoin trading services. Ethereum mining software is a good helper for you to buy bitcoin.

6. Ethereum continues to hold for a long time and will rise again this year. Simu has access to the TS tourism chain. If there is no channel, it's better to invest in ether and dog coin.

7. 1) From the perspective of consensus mechanism, bed, BTC and eth are all POW consensus mechanisms
2) in terms of algorithm, the core algorithm sha256 adopted by bed and BTC has the same value attributes, but bed has established a new economic model through new technology development; Eth uses ethash algorithm
3) from the perspective of mining cost: BTC mining is becoming more and more difficult and has become an arena for mining equipment. At present, the latest 110t ant S19 Pro mining machine has adopted the latest 7Nm chip, and the price of the machine is nearly 20000 yuan. Some low computing power machines, such as the former king ant S9, can only be eliminated, resulting in a huge waste of resources; Eth uses graphics card GPU to mine, and the cost is also quite high; And bed can dig directly with the existing bitcoin miner or the obsolete bitcoin miner with low computing power, so the cost of miner is very low and the waste of resources is reced
4) from the perspective of total amount and upgrade space: the total amount of BTC is 21 million, and the current price is about ￥ 76000; The total amount of eth will reach 113 million, and the current price is about 2500 yuan; The total amount of bed and BTC is 21 million, and there is a huge space for upgrading.

8. For your reference! PTN technology features full service carrying capacity in the allip era, to solve a small amount of TDM service transmission, circuit simulation must be used. PTN is to carry traditional services through PWE3 edge to edge pseudo wire simulation technology and LSP elastic packet pipeline
PWE3 is a layer-2 bearer technology, which is suitable for ATM Asynchronous transfer mode, Ethernet, low-speed t

The fault code etht indicates that the frequency converter is overloaded and open circuit. Treatment method:

1. check whether the power of the frequency converter matches the power of the motor. If the power of the frequency converter is less than the power of the motor, the frequency converter matching the power of the motor should be replaced

2. if the inverter power matches the motor power, check whether the motor load exceeds the motor rated load. If it exceeds the motor rated load, rece the load or replace the high-power motor and the corresponding inverter

3. check whether the motor spindle is stuck. If it is stuck, remove the fault and try again

< / OL >


note: reset the frequency converter when starting again. If the frequency converter is reset, the internal thermal integration data of electronic over-current protection will be initialized

10. From the perspective of configuration, there is no difference. From the perspective of view, one is to view the interface information and the other is to view the aggregation port information.
