bitcoin (BTC) is a digital currency with a total amount of 21 million. It has the characteristics of decentralization, globalization and anonymity, just like the Internet. It means that transferring bitcoin to the other end of the earth is as simple as sending e-mail, low-cost and unlimited. Bitcoin is also used in cross-border trade, payment, remittance and other fields
the liquidity and limitation of bitcoin determine that bitcoin can act as a monetary function equivalent to general equivalent, or as a measure of money, but this measure is not a physical measure like gold, but a digital proct
related concepts:
1. Address
the address of bitcoin world looks like this. The address itself is just a string of codes, just like your bank account number 321 million 3288372, which is used to mark an account. Everyone can have countless addresses. The address is public
2. The bank records how much money there is in the bank account
the amount of money in the bitcoin address is recorded by the whole bitcoin network. Each complete bitcoin data will record how many bitcoins are stored in this address
each node participating in the bitcoin network can save a complete of bitcoin data, and everyone has a backup on hand to prevent counterfeiting
3. The key (private key)
the key is another string of characters you only know. The key is used to operate the money in the bitcoin address. Key and address are the relationship between a key and a lock. Each address has only one password, and each password also operates a bitcoin address
with the key, you can control the money in the bitcoin address and pay to anyone. The key should be absolutely safe. The lost or deleted key can never be found, and the money in the corresponding bitcoin address can never be used
the key needs to be kept absolutely secret. Anyone who knows the key can steal all your bitcoin
4. Wallet
the transaction process of bitcoin will involve a lot of complex calculations. In order to simplify the operation, we have made wallets. The wallet has client software on the computer, and also has an online web version. The function of the wallet is to pay with a little touch, and the complicated calculation behind it is left to the wallet to complete
5. Security
if you use the computer client software, you can recommend multibit or bitcoin QT. Both are official software recommendations for the bitcoin community. The installation of these two softwares must be downloaded directly from the official website, and the check code must be checked before and after downloading. This is to prevent someone from tampering with wallet software and stealing keys
6. mining
about every 10 minutes, some new bitcoin will appear in the bitcoin network, which can be imagined as throwing money in the sky. Whose pocket these scattered money fall into mainly depends on whose computer calculates fast. The faster you calculate, the more likely you are to find the money. Mining is to use the computer to calculate, to pick up the money< br />
warm tips:
1. The above explanations are for reference only, without any suggestions
2. Before investing, it is recommended that you first understand the risks existing in the project, and clearly understand the investors, investment institutions, chain activity and other information of the project, rather than blindly investing or mistakenly entering the capital market. Investment is risky, so we should be cautious when entering the market

the value of virtual currency is that it is based on blockchain technology, has high security, and is suitable for being a decentralized currency after a period of depression, the price of bitcoin has recovered again recently, standing at the price of US $40000, which is the biggest rebound in the price of bitcoin since this month. In fact, since last year, the bitcoin market has ushered in a wave of rising prices. Some analysts say that the main driving force for the rise is that large financial institutions begin to enter the market and take bitcoin as a part of their asset allocation. Some well-known investment companies and fund companies, and even conservative insurance companies regard bitcoin as one of the investment options
the initials of bitcoin are used to represent the concept of bitcoin or the whole bitcoin network itself. For example: "today I learned something about the bitcoin agreement."
bitcoin without capital letters indicates a unit of account. For example: "I transferred 10 bitcoin today." The unit is also usually abbreviated as BTC or XBT
bitcoin address
bitcoin address is like a physical address or an e-mail address. This is the only information you need to provide when someone pays you bitcoin. An important difference, however, is that each address should only be used for a single transaction
peer to peer network
peer to peer network is a system that allows a single node to interact directly with other nodes, so that the whole system can operate like an organized collective. For bitcoin, the bitcoin network is built in such a way that each user is spreading the transactions of other users. And importantly, there is no need for the bank to be a third party<
hash rate
hash rate is a measure of bitcoin network processing capacity. In order to ensure security, bitcoin network must carry out a lot of mathematical operations. When the network reaches a hash rate of 10th / s, it can perform 10 trillion calculations per second
transaction confirmation
transaction confirmation means that a transaction has been processed by the network and is unlikely to be revoked. When a transaction is included in a block, an acknowledgement is received, and each subsequent block corresponds to an acknowledgement. For a small amount of transaction, a single confirmation can be regarded as safe. However, for a large amount of transaction such as US $1000, it is reasonable to wait for more than six confirmations. Each confirmation exponentially reces the risk of cancellation
blockchain
blockchain is a public record of bitcoin transactions in chronological order. The block chain is shared by all bitcoin users. It is used to verify the permanence of bitcoin transactions and prevent double consumption<
cryptography
cryptography is a branch of mathematics, which allows us to create mathematical proofs that can provide high security. Cryptography is also used in e-commerce and online banking. For bitcoin, cryptography is used to ensure that no one can use the money in other people's wallets or break the blockchain. Cryptography is also used to encrypt wallets, so you can't use wallets without a password<
signature
cryptography signature is a mathematical mechanism that allows people to prove ownership. For bitcoin, a bitcoin wallet is associated with its private key by some mathematical magic. When your bitcoin software signs a transaction with the corresponding private key, the whole network will know that the signature matches the spent bitcoin. However, no one in the world can guess your private key to steal your hard-earned bitcoin
wallet
bitcoin wallet is roughly the equivalent of physical wallet in bitcoin network. The wallet actually contains your private key, which allows you to consume the bitcoin allocated to the wallet in the block chain. Like a real wallet, each bitcoin wallet displays the total balance of all bitcoins it controls and allows you to pay someone a certain amount of bitcoin. This is different from the credit card used by merchants to dect money
block
a block is a record in the block chain, which contains and confirms the transactions to be processed. On average, a new block containing transactions is added to the block chain by mining every 10 minutes
al consumption
If a malicious user tries to pay bitcoin to two different payees at the same time, it is called al consumption. Bitcoin mining and blockchain will reach an agreement on the network that one of the two deals will be confirmed and considered valid
private key
the private key is a secret data block that proves that you have the right to consume bitcoin from a specific wallet. It is implemented through a cryptographic signature. If you are using wallet software, your private key is stored in your computer; If you are using an online wallet, your private key is stored on a remote server. Don't disclose private keys, because they allow you to consume the bitcoin in the corresponding bitcoin wallet
Mining
bitcoin mining is a process of using computer hardware to do mathematical calculation for bitcoin network to confirm transactions and improve security. As a reward for their service, miners can get the Commission included in the transaction they confirm, as well as the newly created bitcoin. Mining is a professional and competitive market. The bonus is divided according to the amount of calculation. Not all bitcoin users mine, and it's not easy to make money from mining
bit
bit is a common unit to indicate the sub unit of a bitcoin - 1000000 bit is equal to 1 bitcoin (BTC or B & # 8422;), This unit is more convenient for marking tips, goods and service prices
BTC
BTC is used to mark a bitcoin (B & 8422;) The common unit of.
