Currency lot

⑴What does the diamond hand in the currency circle mean

Token is an encrypted virtual currency. It consists of a symbol that acts as a representation. In the coin circle, BTC (Bitcoin) and eth (Ethereum) are considered the leading coins.

There are more and more tokens issued on the market, and there are thousands of tokens. According to different types, tokens can be divided into equity tokens, application tokens and debt tokens.

A token is just a string of numbers in a blockchain accounting system. It has no intrinsic value, and only by giving it a certain value can it be linked to the value system of the real world. Tokens are blockchain native tokens or built-in tokens.

Tokens can be transferred and traded in the blockchain system, and holders can eventually exchange with the issuer for the external assets or interests they represent. Converting external assets or interests into tokens is an asset digitization process.

This token is also referred to as a “blockchain asset”. The fundamental value of an asset-backed token is derived from the value of the actual asset it represents.

2 How does the currency circle make money?

About digital currency, tell me your opinion, listen to it, and laugh it off if it doesn’t make sense.
Currency, as a measure of value in a transaction, does not necessarily have value in itself, it can only be used as an intermediate unit of measure. It is as if my country only has RMB as legal tender, which means that government guarantees have value. If it is like those war-torn areas, ten pounds of currency may not be able to buy an egg, which is the reason.
Speaking of digital currency, digital currency, until now, no country has recognized it as the currency in circulation in its own country. It seems that last year or the year before, our country also banned some, so in this case, digital currency, only You can sell at a higher price than you bought it, and you can make money. But digital currency itself does not have any value, and unlike stocks, it is your ownership of a listed company. So, when you can’t find someone to buy digital currency, it’s worthless.
Ponzi scheme in history, Dutch tulips, when they were the most expensive, a tulip was worth buying a house, and when no one bought it, all the tulips rotted. Get a potato. Therefore, Buffett said that digital currency is a bubble and a scam, and it is estimated that this is what he thinks.
In addition, there is a saying in the stock market that when the aunts of the vegetable market start discussing stocks, it is the time when the stock market peaks. I think this also applies to digital currency. When many people are discussing how to make money, when they can make a lot of money, it is the time when the risk has accumulated to a great extent. At this time, if you go in, you may be trapped.

⑶ What do we need to know about the currency circle?

If you have just entered the pit currency circle and are about to start digital currency, don’t worry, be quiet first Take a look at the following content, I guess it will help you.

1. What is a digital currency wallet
Many people say that digital currency wallets are used to store digital currency. Generally speaking, there is no problem in understanding this, but in fact, digital currency money is packaged in It is not digital currency, but a tool for holding keys (private key and public key). With the key, you can have the right to control the digital currency on the corresponding address. Using the digital currency payment address generated in the wallet, you can accept The digital currency that others transfer to you can also transfer the digital currency you own to others. In layman’s terms, it can be understood as a digital currency used to store and trade.

Second, the structure of the digital currency wallet
1. Address:
The wallet address is a string of strings, which is used to transfer money. The wallet address can be understood as a bank card number, which can be Tell anyone that anyone who knows your wallet address can transfer digital currency to your wallet address. Different digital currency addresses are also different. For example, the addresses of eos and btc are different.
2. Private key
The private key is a random number generated by the system through a cryptographic algorithm according to the random factor in the user’s environment. It can be regarded as a bank card password. For each transaction, the payer must issue the private key and the signature generated by the private key.
3. Public key
The public key is generated by the private key, and appears in pairs with the private key. The public key can calculate the address, which is mainly used to generate the address.
4. Password
When creating a wallet, you need to set a password. The main use of the password is: 1. The payment password when transferring money; 2. The password needs to be verified when importing the wallet. Passwords are actively set by the user, but are much less secure than private keys. The password mainly plays the role of double protection.
5. Mnemonics
The mnemonic is another form of the private key, and its function is equivalent to the private key. The mnemonic is generally 12-15 or more English words.�� words, you can find the private key and restore the wallet through the mnemonic phrase, so the mnemonic phrase is very important, and most wallets will prompt the user to backup the mnemonic phrase in order to restore the wallet.

3. Classification of digital currency wallets
It can be roughly divided into two categories, hot wallets (online wallets) and cold wallets (offline wallets)
(1) Hot wallets:
Also known as online wallet, it includes light wallet and heavy wallet (full node wallet). Wallets that need to be kept online can perform transaction operations directly.
1. Light wallet:
Does not store the complete blockchain, but only saves data related to itself. It is small in size and can be run on mobile phones, computers, web pages, etc.
Advantages and disadvantages: does not take up memory, supports a variety of digital assets, good user experience, fast for beginners, but transaction verification is slightly slower

2, heavy wallet (full node wallet)
It maintains all blockchain data, is completely decentralized, and synchronizes all data. With better privacy, the validity of transaction data can be verified locally.
Advantages and disadvantages of hot wallets: It has better privacy and faster verification of information, but it needs to synchronize data before each use, takes up a lot of hard disk space, and does not support multiple digital currency transactions.
(2) Cold wallet:
A cold wallet is a wallet that is not connected to the Internet, also called an offline wallet; such as a professional hardware device, or writing the private key (mnemonic) on paper.
1. Hardware wallet
Hardware wallet is to use professional hardware to store digital currency, and store the private key of digital assets in a chip, which is isolated from the Internet and is plug-and-play.
2. Paper wallet
Write the private key on paper for storage, and then delete it.

Advantages and disadvantages of cold wallets: relatively safe, but it is very troublesome to create wallets and transactions. It is more difficult for beginners to operate, and the price of wallets is relatively expensive, generally ranging from several thousand to tens of thousands of yuan. If you don’t have a large amount of digital assets, you can ignore it.

4. How to choose a digital currency wallet
Light wallets are easier and more convenient to use, generally support multiple currencies, and are generally suitable for newcomers to the currency circle or transaction and storage capacity Not used by small users. For example, the geekwallet
hardware wallet is not connected to the Internet, and has higher security, but the operation is relatively complicated, and it is generally suitable for users with a large amount of transactions and storage.

5. Precautions when using digital currency wallets

1. Keep the password well, once lost, it cannot be retrieved. However, you can reset your password with a mnemonic phrase (provided you keep the mnemonic phrase safely).
2. Keep the private key, the owner of the private key is the real owner of Bitcoin.
3. Keep the mnemonic phrase. Once someone gets the mnemonic phrase, others can transfer all the blockchain assets in the wallet corresponding to the mnemonic phrase.

⑷ What is the transaction volume in the currency circle

Reflects the number of transactions and the number of people who buy and sell. Generally, it can be measured by the number of transaction coins and transaction amount. ?

⑸ What are some professional terms in the currency circle

Explanation of 26 common terms in the blockchain industry

1, Blockchain— —Blockchain

Blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. is a shared distributed ledger in which transactions are permanently recorded through additional blocks.

2. Block—Block

In the Bitcoin network, data is permanently recorded in the form of files, which we call blocks. A block is a set of records of some or all of the latest Bitcoin transactions that have not been recorded by other previous blocks.

3. Node – Node

A copy of the ledger operated by the participants of the blockchain network.

4. Decentralization

Decentralization is a phenomenon or structure that must appear or exist in a system with many nodes or in a group with many individuals. The influence between nodes will form a nonlinear causal relationship through the network.

5. Consensus mechanism

The consensus mechanism is to complete the verification and confirmation of the transaction in a very short time through the voting of special nodes; for a transaction, if the interests are irrelevant If several nodes can reach a consensus, we can think that the whole network can also reach a consensus on this.

6. Pow – Proof of Work

Proofof Work means how much currency you get, depending on the amount of work you contribute to mining, the better the computer performance, the more money you get There will be more mines.

7. PoS – Proof of Stake

Proofof Stake, a system for distributing interest based on the amount and time of currency you hold. In the POS mode, your “mining” The profit is proportional to your coin age, and has nothing to do with the computing power of your computer.

8. Smart contracts

Smart contracts are computer protocols designed to spread, verify or execute contracts in an information-based manner. Smart contracts allowConduct trusted transactions without third parties, which are traceable and irreversible.

9. Timestamp

A timestamp refers to a string or encoded information used to identify the recorded time and date. The international standard is ISO 8601.

10. Turing completeness

Turing completeness refers to the ability of a machine to perform computations that any other programmable computer can perform.

11. Dapp – Decentralized Application

It is an open-source application that runs automatically and stores its data on the blockchain in the form of cryptocurrency tokens. Form incentives and operate with protocols that show proof of value.

12. DAO – Decentralized Autonomous Organization

It can be considered as a company that operates without any human intervention, and gives all forms of control to a set of Broken business rules.

13. PrivateKey – Private Key

A private key is a string of data that allows you to access a token in a particular wallet. As cryptocurrencies, they are hidden from all but the owner of the address.

14. PublicKey – public key

is paired with the private key. The public key can calculate the address of the coin, so it can be used as a certificate for owning the coin address.

15. Miners

A computing device or software that attempts to create blocks and add them to the blockchain. In a blockchain network, when a new valid block is created, the system generally automatically gives the block creator (miner) a certain amount of tokens as a reward.

16. Mining Pool

It is a fully automatic mining platform, which enables miners to contribute their respective computing power to mine together to create blocks and obtain block rewards. And distribute profits according to the proportion of computing power contribution (that is, the mining machine accesses the mining pool – provides computing power – obtains income).

17. Public chain

A completely open blockchain refers to a blockchain that can be read by anyone, can be sent by anyone, and the transaction can be effectively confirmed. Everyone in the world can participate in system maintenance, and anyone can read and write data through transactions or mining.

The write permission is only for a blockchain of a certain organization or a specific few objects. Read permissions can be open to the outside world, or restricted to any degree.

19. Consortium chain

The consensus mechanism is a blockchain jointly controlled by a number of designated institutions.

20. Sidechains

pegged sidechains technology (pegged sidechains), which will realize the transfer of bitcoin and other digital assets between multiple blockchains, which This means that users can access the new cryptocurrency system while using their existing assets.

21. Cross-chain technology

Cross-chain technology can be understood as a bridge connecting various blockchains, and its main application is to realize atomic transactions, asset conversion, regional Information exchange within the blockchain, or solving Oracle problems, etc.

22. Hard forks

The blockchain has a permanent divergence. After the release of the new consensus rules, some nodes that have not been upgraded cannot verify the blocks produced by the upgraded nodes. Usually a hard fork happens.

23. Soft fork

When the new consensus rules are released, nodes that have not been upgraded will produce illegal blocks because they do not know the new consensus rules, which will generate Temporary fork.

24, Hash——Hash value

Generally translated as “hash”, there are also direct transliteration as “hash”. Simply put, it is a function that compresses a message of any length into a message digest of a fixed length.
