The insufficient space of Ethereum is DAG

1. GPU mining

Hardware

algorithm is difficult to solve in memory. In order to make DAG suitable for memory, each GPU needs 1-2gb of memory. If you get an error prompt: error GPU mining. GPU memory fragmentation? It means you don't have enough memory. GPU mining software is based on OpenCL, amd GPU will be faster than NVIDIA GPU of the same level. ASIC and FPGA are relatively inefficient, so they are blocked. To get OpenCL for chip integration platform, try:
amd SDK OpenCL
NVIDIA CUDA OpenCL
Ubuntu Linux settings

for this quick guide, you will need Ubuntu 14.04 or 15.04 and fglrx image driver. You can also use NVIDIA drives and other platforms, but you have to find your own way to get an effective OpenCL installation, such as genoil's ethminer fork
if you are using 15.04, go to & quot; Software and updates 〉 extra drives & quot; Set to & quot; Use the video driver & quot; from fglrx for AMD graphics accelerator
if you are using 14.04, go to & quot; Software and updates 〉 extra drives & quot; Set to & quot; Use the video driver & quot; from fglrx for AMD graphics accelerator;. Unfortunately, for some people, this method may not work, because there is a known program error in Ubuntu 14.04.02 that will prevent you from switching to the exclusive graphics drive necessary for GPU mining
therefore, if you encounter this program error, go to & quot; "Software and update" update & quot; Select & quot; Pre release reliable update proposal & quot;. Then, back to & quot; Software and updates 〉 extra drives & quot; Set to & quot; Use the video driver & quot; from fglrx for AMD graphics accelerator;. After restarting, it's worth checking that the drive is now properly installed (for example, by going to & quot; Additional drives & quot;)
no matter what you do, if you are using 14.04.02, once installed, do not change the drive or drive configuration. For example, the use of aticonfig – initial (especially the - F, - force option) will & quot; Destruction & quot; Your settings. If you accidentally change the configuration, you will need to uninstall the drive, restart, install the drive again and restart.

2. The term "difficulty" comes from bitcoin, the pioneer of blockchain technology, which is used to measure the average number of operations needed to dig out a block. Mining is essentially solving a puzzle. Different e-coins set different puzzles. For example, bitcoin uses SHA-256, lightcoin uses script, and Ethereum uses ethash. All the possible values of the solution of a puzzle are called the solution space. Mining is to find a solution among these possible values
these puzzles

3. 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)

4. 2020 is the first year of proction rection. Everyone turns to BTC, BCH, BSV and other currencies. However, you forget eth. As the king of the public chain, ETH will usher in the big upgrade of 2.0 super version in 2020, switching from the pow mechanism to the POS mechanism. In addition, it will face proction rection in March next year, and its circulation will be reced by 10 times. Its impact is no less than that of bitcoin proction. Since the beginning of the year, the trading volume of eth has grown explosively, and the institutional capital has poured in to preempt the layout. However, the current price of eth is only 260 US dollars. With many super favorable blessings, the market expects eth to usher in a super bull market< In theory, the circulation of next year will be reced by 10 times. In theory, the current price of eth is 260x4 = US $1040 (upgrade + expected price after proction rection)

ring this period, the return comparison between holding spot and ETF fund is as follows:

1. Holding spot makes 4 times of profit
2. Holding Ethereum ETF fund makes 12 times of profit, Up to 30 times (intelligent position adjustment + fund compound interest calculation)

there is no doubt that the Ethereum ETF launched by bitoffer is the best investment choice!

5. 1、 Recharge
1. Login Z? B account, click finance
2. Select the abbreviated currency of quantum currency and click "recharge". After creating an account, the system will automatically assign you a recharge address to which you can recharge
3. After network confirmation, you can get to your account.

6. Return the result of ifconfig
eth0 to awk for processing
where - F & # 39;:|< br />+'
this is a separator defined by awk and then matched with "BCAST & quot;, Take the content of the fourth column
since your command is not universal, you can't output the result here, but you should intercept the broadcast address

7. Currency tiger global transaction fees platform currency can also be halved, overall not bad

8. Does Ethereum still have room for appreciation? There must be room for appreciation. Moreover, there is considerable room for appreciation.

9. Bitcoin has a lot of room for appreciation, because it is the largest virtual currency, with higher popularity and wider acceptance in the world

10. Dag can find a good balance in decentralization and scalability, which also follows the traditional values of blockchain.
