Bitcoin and
{rrrrrrr}
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 />
bitcoin, a blockchain based digital currency, is often regarded as a global safe haven asset like gold. In this age of global turmoil, even gold has become unreliable and may be confiscated as India has. Some people have begun to think that bitcoin can replace gold, because bitcoin not only has the reserve capacity of gold, but also has some capabilities that gold does not have, such as low handling charges, rapid transfer capacity, decentralization and so on. With the increasing popularity of bitcoin and the decreasing volatility, the status of gold has been threatened
will bitcoin shake the status of gold?
gold has a long history, almost as long as the history of human civilization, and has withstood numerous tests in history. Bitcoin is less than a decade old, but its value has risen sharply. There is no support behind bitcoin. Of course, since the end of the gold standard, there has been no support from other currencies, except that there is no support from the central bank behind bitcoin. It's hard to predict whether bitcoin will exist in the next decade, a hundred years or even a thousand years.
moreover, the number of bitcoin is small, and it is too concentrated in the hands of several big players, which leads to its price instability. This is basically not money. Because as a general currency, an important prerequisite is price stability, otherwise the economic order will collapse.
the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system.
now we can also participate in providing storage space to help those customers who need to store content to keep content fragments, and they will get storage fees; Providing retrieval services, bandwidth, and quickly providing the content customers need will get retrieval fees; Packed blocks, each block confirmed, the network will give a reward. Statistically speaking, the return is higher than that of bitcoin mining.
Decentralization: bitcoin is the first distributed virtual currency. The whole network is composed of users without a central bank. Decentralization is the guarantee of bitcoin's security and freedom
Global Circulation: bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin
exclusive ownership: private key is required to manipulate bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself
low transaction cost: bitcoin can be remitted free of charge, but a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster transaction execution
no hidden cost: as a means of payment from a to B, bitcoin has no cumbersome quota and proceres. If you know the other party's bitcoin address, you can pay
cross platform Mining: users can explore the computing power of different hardware on many platforms
bitcoin is the earliest cryptocurrency and the largest cryptocurrency so far. Bitcoin and blockchain were born at the same time. Like gold, the issuance and launch of bitcoin can not be broken through, and the total amount is up to 21 million. Gold is not issued by any country, it is issued by nature, so most people agree that gold is money
bitcoin is as like as two peas in gold, and how much is the bit currency? Let's take a look at the enring joke in the coin circle. Nine years ago, a programmer traded 10000 bitcoins for two pizzas. This is the first transaction of bitcoin. It also shows that bitcoin can circulate like money. This is the embodiment of the value of bitcoin
if blockchain is compared to flour, then bitcoin is steamed bread made of flour. Flour can also be used to make rolls, pancakes, etc., but the first food made of flour is steamed bread
similarly, bitcoin is the first application of blockchain technology. However, in addition to bitcoin, blockchain technology itself can also be used for many purposes, such as blockchain can effectively solve identity forgery and data tampering of central supervision system
