Bitcoin connected testnet

1. The difficulty of bitcoin block is abnormal. Let's forget it. It's impossible to mine without connecting to the mine pool

2. Bitcoin address and website connection are related to website development

generally speaking, the connection between bitcoin address and website is basically carried out in the website development stage. In website development, we need to call bitcoin related programs in bitcoin development system; Then, by adjusting the website code, the bitcoin address can be connected to the website.

3. Avalon team has developed the world's first "variable computing power cluster system" (hashs for short, hyper array scalable hashing
System). In this system, the concept of single miner no longer exists, but the concept of mole cluster

taking Avalon 40 nm mole as an example, each mole has 295g computing power. According to the actual situation of the mine site, power supply and heat dissipation, users can freely choose to stack 1-40 moles (corresponding to about 0.3t-12t computing power) into a computing power cluster unit, which can be controlled by one terminal, one network cable and one IP address. Revolutionary technological innovation has raised the flexibility and simplicity of mine layout to an unprecedented level.

4. They have 8 years of operation experience, and they should be the oldest in China. Their service is relatively comprehensive. Some friends are their customers, and the evaluation is pretty good.

5. See the server above, don't choose the wrong one. Even if you choose the right server, there are too few servers facing Asia

6. Bitcoin wallet has a large amount of data, many areas and dozens of G's. If it's the first synchronization, it's normal.

7. As long as you are connected to the Internet, you can carry out online bitcoin transmission. The premise is that you have to have a transmission address, and you also have to have bitcoin and a bitcoin account. You can download a bitcoin wallet or register an online wallet. It's very simple. I really don't understand. Go to bitcoin house to search the wallet tutorial.

8.

In addition to the complete implementation of bitcoin's core protocol, bitcoin node software also includes an optional but important function mole -- Wallet:

you can regard the wallet as a safe to store all your keys and addresses, and also encapsulate many technical concepts and details of bitcoin, So that it can be understood and accepted by people other than geeks. Therefore, bitcoin enables node wallet by default. If you want to disable the wallet function, for example, you can set the disablewallet option in the configuration file:

disablewallet = 1

the wallet mole will track all address related transactions managed by it, so it can update the balance information of the wallet in time. This function is very important because there is no concept of account in bitcoin. Bitcoin is e-cash scattered among transactions. If there is no wallet to help track transactions related to our address, it is difficult to figure out how many bitcoins we hold in total

Many RPC calls provided by

nodes are implemented by wallet mole. For example, when we call the getnewaddress command, the wallet mole generates the key and address and automatically adds them to the wallet, so its related transactions will automatically affect the balance of the wallet. Similarly, when we call getbalance, the wallet mole will collect the bitcoin on all addresses and return the total amount

for those who are inexperienced or just start a new job, code review can help them get help from more experienced people, get familiar with the existing specifications and architecture faster, and improve quickly in the new environment and team
for senior engineers, letting other colleagues review the code is concive to spreading experience, knowledge and good practice in the team. The improvement of the level of colleagues will make their work more efficient. And everyone needs to take a vacation. Neither the company nor indivials want to have too much work stagnated because of this. If there are colleagues who are familiar with their work, this problem will be solved very well
like many other things, the hardest part of code review is to take the first step. Once started, every minute spent in the review process is quickly multiplied. If you are not in a position where you can change the team process at once, you can at least start to practice with a few colleagues who agree with this matter. When the value begins to embody, I believe others will be willing to follow suit.
