BTC query blockchain

1.

blockchain is an important concept of bitcoin. It is essentially a disintermediated database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains the information of a bitcoin network transaction, Used to verify the validity of its information (anti-counterfeiting) and generate the next block

the data on bitcoin blockchain, which we call the data on the chain, generally includes: bitcoin active address, new address, continuous active address, reactivated address, transaction volume on the chain, number of transactions on the chain, TSP, transaction transfer fee on the chain, large amount transfer, mining difficulty and other data

we generally query the data on some blockchains through the blockchain browser, Bitcoin's more commonly used blockchain browsers are:

2. Have you backed up the private key file corresponding to the address? Just back it up. No backup, no backup
Josn file.

3. Wallet balance and address balance are different concepts. Sometimes they are equal or unequal, which is caused by the change mechanism. The bad 8btc must be on the change address, which only exists in the wallet and is not displayed on the client. Your balance is still 68.89214424. View the original post & gt& gt;

4. All the revenue and expenditure records and balance of my computer wallet client are right, and it is impossible that there are 28 revenue and expenditure records that are not recorded, and the client often updates them. I can't understand some of them on blockchain. For example, I transferred one expenditure to 0.001btc on dice, but it was shown on the website: 1.99 BTC and (satoshidice 97%) 0.01 BTC, a total of - 2 BTC to view the original post & gt& gt;

I believe that many people will see a lot of advertisements related to page games when they are watching videos or browsing web pages. These advertisements are basically overwhelming. As long as we surf the Internet, we can see them, so that we can say that they are defenseless and annoying. If it's the kind of game that seems to be well made, maybe everyone won't be so annoying. The key point is that these advertisements seem to know that this kind of game is absolutely shoddy, and it seems to be a game that has fallen behind for more than ten years. There are a few questions that people can't figure out. Are those stars endorsing this kind of "junk game" or why they are endorsing this kind of game? Don't they feel bored

so the game manufacturers want to let people know that there is such a game, so the main cost is all spent on the publicity. Let more people know that there is such a game. When I was young, because I was poor, I couldn't dominate the world in this game. Now it's normal for me to have money to have a good time. After all, what's money for? Consumption is not consumption? It is said that the monthly revenue of blue moon, which was popular all over the world at that time, could reach nearly 100 million. It was easy to make money by making a few bad servers, transplanting the code of legend, which almost everyone knows, and inviting a few celebrities to speak for it. So you should know why this broken game can invite so many stars to speak for it

6. If it's just a little fuss or novice, it's recommended not to register blockchain. You can register some bitcoin trading platforms, or use bitcoin QT, mutibit and other client wallets. I hope it can help you.

7. The transaction website should use the full node controlled by itself, that is, the API of the blockchain to verify the recharge. But there is also the possibility that you said. For technical questions, you can go to Babbitt. There are some big cows there.

8. Bitcoin the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software and P2P network are designed and released. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system

9. I wonder why a newcomer should contact and use his wallet. A lot of new people ask how to use their wallets just like you, and the explanation is very troublesome. In fact, if you're a newcomer, you don't need to use your wallet Are there new people mining now? The brain is broken
it's good for you to directly exist in a large website. Each website now has several verifications. SMS verifies Google token. Why don't you just click BTC to withdraw cash when you want to use it? I think it's easier to lose it if I keep it myself. You're not worried about website failure, are you? If the large websites can be gone, it means that BTC has completely collapsed, and it's useless for you to ask for it
and why do you want to use the online wallet? I'll go to see if you can use the multibit wallet. This wallet doesn't need to be updated. The data is very fast
at the beginning, study the technical principle and market platform first. Don't worry about wallet. Now it's not convenient to pay for BTC when you go out, and your whole online wallet is meaningless.

10. The arrival of bitcoin needs block confirmation, at least more than 6 confirmations
