Cold wallet is the core technology of digital currency
bitcoin wallet can be divided into cold wallet and hot wallet according to the storage method of private key
01. A cold wallet is a wallet that can't access your private key on the Internet
cold wallets often rely on "cold" devices to ensure the security of bitcoin's private key, such as computers that are not connected to the Internet, mobile phones, small notebooks with private key addresses, etc. Cold wallet avoids the risk of hackers stealing the private key, but may face physical security risks, such as computer loss and damage
02. Hot wallet refers to the wallet that can access your private key on the Internet
Hot wallets are often in the form of online wallets. When using hot money package, it is better to set different passwords on different platforms and open secondary authentication to ensure the security of your assets
wallet is actually "a management tool for private key, address and blockchain data".

The Italian design is totally different from the French design
the French design is to show off their design skills and use all the knowledge in the design book in one car, for fear that you don't know how good I am at "design"
The Italian design focuses on the vehicle itself. Better highlight the identity of this car, such as sports Ferrari, luxury aggressive karlmann kingdo you like this American, Italian karlmann king

the red suit of the blaster hero can be obtained by dropping the level and opening the weapon or equipment box
among them, the higher the difficulty of level, the higher the possibility of obtaining
and the probability of high-grade box is higher than that of ordinary box
at the same time, there is a great probability that red weapons and equipment will be dropped in daily tasks
I hope my answer can help you
you should comfort him more, introce the advantages of this proct more, and he will buy it!
As far as I know, the current snapdragon 865 is not comparable to the current computer CPU. Due to the platform mismatch, the CPU calculation is inconsistent
Theinstruction set is inconsistent. The structure is inconsistent. They can't compare together. Compared with the computer CPU, it is an aircraft with large space and more passengers, and has its own flight mode and flight route. The CPU of mobile phone is equivalent to car, and it also has its own characteristics. It's not a car here. This platform has decided your biggest operation mode
it's like a plane in the air with a speed of 1000 km / h and the highest fighter with a speed of 7000 km / h. Because the sky platform can provide such speed for him. The car doesn't work. It can support the speed per hour{ RRRRR}
well, in recent years, not only mobile phones, but also the expectation of small partners on mobile phones is increasing. There is a saying called handle, long, no handle. That's how much people rely on mobile phones now. Now people use computers less and less frequently. In addition, many computer client development released mobile client, invisible
mobile phone & lt; Heart & quot; Only the cover size of the nail, but according to the highly integrated SOC identity, this chip perfectly explains & lt; Sparrow has all five internal organs; What is the definition of
if the architecture and process of instruction set determine the ability of SOC (see "popularization of hard core science! Why does SOC performance depend on architecture and process
”， The visual combat effectiveness of SOC depends on the specification of CPU GPU mole. Spouse 865 is the SOC with the highest comprehensive performance in Android mobile phone circle, which comes from the more powerful integrated GPU
next, let's analyze SOC and look at two important moles that affect its absolute performance
CPU:
performance basis
in the components of SOC, CPU is one of the most important core units, which can be understood as the core processor on PC, but its strength is mainly affected by the following parameters
SOC for mobile phones are & lt; ARM processor;, There are three forms of cooperation between arm and chip manufacturers
native cortex-a architecture; Native & quot The architecture includes cortex-a7x at performance level and cortex-a5x at performance level. The former is used as & lt; Big core;, Now the SOC is on cortex-a7x
The higher the version ofcortex-a architecture, the better the performance
the latter is & lt; Small nucleus;, Cortex-a73 and cortex-a53, cortex-a75 and cortex-a55 & lt; Getting married;, In the short term, arm has no plan to update the core architecture of performance level
semi custom architecture based on cortex
after obtaining the native cortex-a architecture of arm, chip manufacturers can transform it to some extent to achieve higher performance, more functions or lower power consumption
Qualcomm's snapdragon SOC has been using & lt; Kryo” They are semi customized according to the native cortex-a architecture, which is often referred to as & lt; Magic Reform & quot
Huawei started with Kirin 980, including the latest listed Kirin
820 is not only the main cortex-a-based, but also the semi customized magic reform in theory
instruction set based self-developed architecture
chip manufacturers license the instruction set of arm, and develop chips based on it, which can be classified as & lt; Self research & quot; Architecture
for example, kryo core adopted by snapdragon 820, Samsung oose core and Apple's SOC after A5 adopt self-developed CPU architecture based on ARM instruction set
from the point of view of the cost of arm license, the license cost of native architecture is the lowest, and the license based on instruction set is the highest
from the point of view of performance, there is obvious performance inhibition between architectures in different periods. For example, cortex-a77 is inherently stronger than cortex-a76, but there is little difference among native, magic modified and self-developed architectures in the same period
