this is the general content of popular science. If you want to know more about it, you can take a look at Nakamoto's paper and the official popular science video below
The price of a bitcoin soared from more than $20000 to $40000. This can not help but arouse my research interest, or simply understand what bitcoin is, what its mechanism looks like, and uncover its mystery. Therefore, after a simple search of some information and some understanding of the special currency, I sorted out the information on hand< (3) purpose: decentralize, rece risk
all servers in the distributed network can store and process data, and each server has equal status, which can store more data and has higher security<

@ block chaining
to make complaints about the center is code open source, you can check, ensure that they will not install viruses and upload your personal data. p>
-
it doesn't matter if the wallet goes out of business, just export the private key and save it to other wallets
-
the exchange transfer fee is about 30 yuan per time, and the transfer from your wallet is only a few cents per time
3. Computers with bitcoin clients are called nodes, and all nodes on the Internet constitute a bitcoin network. Whenever a new bitcoin is generated and traded on a node, the node will broadcast to the nearby bitcoin node, and finally the whole network node will record the transaction information
in the bitcoin network, each node with a client installed has a distributed database to manage bitcoin proction, transaction, query account balance records, and update and record the latest records of changes in the bitcoin system
when you want to send 10 bitcoins to your friends. You need two things, one is the bitcoin address, the other is the corresponding private key. Bitcoin addresses are different from bank accounts. You don't need to sign a bunch of documents to apply for them. They are randomly generated, just a string of letters and numbers. The private key is also a similar string, but this is strictly confidential. The bitcoin address is like a transparent piggy bank. Everyone can see what's in it, but only the person with the private key can open it.
after you send the transaction application, the surrounding nodes will check whether your account has 10 bitcoins. If there are, they will agree to the transaction, and broadcast the message to the nearby nodes, which will be transmitted from one to ten, and from ten to 100, Soon the whole network will confirm the transaction information and write it to the block. Your friend will receive 10 bitcoins, and the transaction will be completed.
if you want to send small bitcoins, in theory, digital currency can be cut infinitely. At present, the smallest bitcoin unit is called "Nakamoto Tsung", which is equivalent to 0.00000001 bitcoins.

4. blockchain is a technology, but it is not a single technology, but the result of the integration of a variety of technologies, including cryptography, mathematics, economics, network science and so on. You can think of it as a distributed shared accounting technology, or as a database, but the database is jointly maintained by all nodes in the chain, and each node has an account book. Because the account books of all nodes are consistent, different nodes can trust each other, and there is no doubt about the data, so we all say that the blockchain has realized trust technically. For detailed professional technology, you can consult some professional technology companies, such as Jinbo technology, which focuses on the development of blockchain related procts, professional R & D team and perfect after-sales service, and you can consult by telephone.
5. The essence of a blockchain wallet is a private key, which is a random hash string. If you have the private key, you have the right to use the wallet. According to the storage method of the private key, it can be divided into cold wallet and hot wallet
cold wallet refers to the wallet where the network can't access your private key. Generally, it will take a notebook to record it. Although it avoids the risk of being stolen by hackers, it may also be lost
a hot wallet is a wallet that can access your private key on the Internet. Hot wallets are often in the form of online wallets, which are not easy to lose, but also have risks.

6. Hello
ordinary investors and users can use wallets to achieve what needs
What do you think of when you think of wallet
1. Hot wallet, cold wallet, observation wallet—— Realize the most basic function of a wallet: storage
2. DAPP entry of different public chains—— The entrances of the coin holders to the dapps of the public chains
3. Flash cash, direct trading in the exchange and cash out—— The transaction and Realization of digital assets
4. Pay attention to the market information to understand the currency price
Yes, some blockchain wallets have been implemented. It makes people feel like "a small purse, a big world". The actions that users want to complete in the blockchain world can be basically solved in their wallets
take the tokenpocket wallet that I often use as an example< How to understand hot wallet, cold wallet and observation wallet
Hot Wallet: Online wallet, online wallet. It is convenient to withdraw money. You can also check the wallet assets, balance and transaction records at any time
cold Wallet: it's an offline wallet. Since it's offline and not connected to the Internet, how can I realize it when I need to transfer money or withdraw money? Just watch your wallet
observe Wallet: a wallet that observes the assets of a cold wallet and assists in withdrawing the cold wallet's assets< Second, TP SDK integrates Tron
the latest version of TP SDK now supports Tron, that is to say, when the independent DAPP on the wave field public chain is connected to the tokenpocket SDK, it can realize the operation of Tron authorization login, data signature, token transfer, transaction signature, etc
in this way, the development of Tron independent DAPP is greatly accelerated
Third, asset collection function
we usually have such a phenomenon: everyone has multiple accounts, and these accounts have the same token. If you want to collect the same asset on these different accounts, you need the asset collection function
there is a problem: if the passwords of all your accounts are the same, you can authorize them once. If the passwords are different, you need to authorize each time
note: please do not close or exit the collection interface before the completion of the collection operation to prevent errors
Fourth, experience the colorful DAPP on each public chain
in the TP interface, select the Tron category to enter the Tron DAPP page. Play all kinds of DAPP, or enter other public chains, such as EOS, Jingtong, etc
there are more functions in the wallet, waiting for further exploration.

7. 0.001 bitcoin, and how much RMB, is multiplied by the current price, for example, 17881, 1m bitcoin is equal to 17.881
8. Bank of China can conct foreign exchange trading. You can open an account at the branch
it's convenient to buy and sell on the phone and online

9. 1. By judging the length of the file, request the length of the file from the server, and then download it back for comparison
2. The best thing is to verify the MD5 code of the file. The server needs to send an MD5 code of the downloaded file to match with the MD5 code of the local file.

10. Blockchain wallet is a software to save all kinds of blockchain coins (bitcoin, Ethernet, etc.)
the key and address are the bank card number and password in the blockchain world
the essence of wallet is to save the key, that is, to save the bank card and password
Why do you need wallet to save the password? Unlike the bank card password, the password of blockchain currency is a string of 256 bits of binary numbers without any meaning
there are several terms of Ethereum wallet that must be deeply understood, otherwise it may cause the loss of blockchain assets. These terms are address, password, private key, mnemonic and keystore. Taking bank account as an analogy, the corresponding contents of these five words are as follows:
address = bank card number
password = bank card password
private key = bank card number + bank card password
mnemonics = bank card number + bank card password
keysore + password = bank card number + bank card password
keysore ≠ bank card number
if you forget your wallet information, What are the consequences? There are several situations:
(1) if you forget the address, you can use the private key, mnemonic words and keystore + password to import the wallet to retrieve it
(2) if you forget the password, you can use the private key and mnemonic words to import the wallet to reset the password
(3) if the password is forgotten and the private key and mnemonic words are not backed up, the password cannot be reset and the token cannot be transferred, which is tantamount to losing control of the wallet
(4) if you forget the password, the keystore will lose its function
(5) if you forget the private key, you can export the private key as long as your wallet is not deleted and your password is not forgotten
you can use mnemonic words,
(7) if you forget mnemonic words, you can import wallet to backup mnemonic words through private key and keystore + password
(8) if you forget the keystore, as long as your wallet is not deleted and your password is not forgotten, you can back up the keystore again
mnemonics,
it can be seen from the above that as long as there is a message in "private key, mnemonics, keysore + password", the wallet is there. Therefore, a good backup of "private key, mnemonics, keysore + password" is the most critical
the Xueshuo innovation blockchain Technology Workstation of Lianqiao ecation online is the only approved "blockchain Technology Specialty" pilot workstation of "smart learning workshop 2020 Xueshuo innovation workstation" launched by the school planning, construction and development center of the Ministry of ecation of China.
