The digital currency wallet is the hardware wallet, which means that the private key of digital assets is stored in a single chip, isolated from the Internet, plug and play. Hardware wallet can't guarantee 100% security. For example, if a geek gets your hardware wallet and doesn't know your private key, it may be cracked by violence. It's just one of the safest storage methods compared to other storage methods
many block chain entrepreneurs at home and abroad are optimistic about the development of this field, so they begin to build more hardware wallets. In the case of the exchange being stolen a lot of money and the software wallet being stolen from time to time, many investors regard the hardware wallet as the last moat
extended information:
whether the hardware wallet is safe
the hardware wallet can not guarantee 100% security. For example, if a geek obtains your hardware wallet, it may be cracked violently even if it doesn't know your hardware wallet immediately. It's just one of the safest storage methods compared to other storage methods
of course, there are exceptions, such as you have unlimited brain power and never forget. It's better to save it anywhere than in your own mind

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. Look at the picture. Your MOSFET is wrong. It should be n-channel. Your MOSFET is p-channel
in addition, your R40 doesn't need to be used. Now the partial pressure is about 1.8V, which is greater than 1.5V, but it is very dangerous.

7. Ltc3789 is a high-performance, step-down boost switching regulator controller, which can operate when the input voltage is higher, lower or equal to the output voltage. The device uses constant frequency and current mode architecture, so it can provide a phase-locked frequency up to 600kHz, and an output current feedback loop provides battery charging support. With a wide input and output range of 4V to 38V (up to 40V) and seamless and low-noise conversion between working areas, ltc3789 is an ideal choice for automotive, telecommunications and battery powered systems
the operation mode of the controller is determined by the mode / pllin pin. The mode / pllin pin can choose between pulse skip mode and forced continuous mode operation, and allows the IC to be synchronized to an external clock. Pulse hopping mode can achieve the lowest ripple under light load, while forced continuous mode works at a constant frequency to meet the needs of noise sensitive applications
when the output is within 10% of its design set point, an indication signal will occur on a power good output pin. The ltc3789 is available in a flat 28 pin 4mm x 5mm QFN package and a narrow body SSOP package

9. The internal resistance of the battery is too large. There is something wrong with the MOS transistor.
10. This is an input pin, which is the voltage feedback terminal correctly
look at its function block diagram. It is connected to the input end of the upper and lower limits of the two comparators; The function is like clamping the VSENSE pin at 0.8V.
all you need to do is to send the voltage you want to divide 0.8V to VSENSE through two resistors
