unlike all currencies, bitcoin does not rely on a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has scarcity
after bitcoin transaction data is packaged into a "data block" or "block", the transaction is initially confirmed. When a block is linked to a previous block, the transaction is further confirmed. After six block confirmations in a row, the transaction was irreversibly confirmed. Bitcoin P2P stores all transaction history in a "blockchain.".
1. Bitcoin:
also known as "bitcoin", is a kind of network virtual currency. Internet users can use bitcoin to buy some virtual goods, such as clothes, hats and equipment in online games. Internet users can also use bitcoin to buy real goods
2. The origin of bitcoin: the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, the open source software was designed and released, and the P2P network on it was constructed. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation
extended data :
the generation principle of bitcoin:
starting from the essence of bitcoin, the essence of bitcoin is actually the special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique
compared with RMB, bitcoin is the serial number of RMB. If you know the serial number of a note, you will have the note. The process of mining is to constantly seek the special solution of this equation system through a huge amount of calculation. This equation system is designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million
historical background
bitcoin is one of the first currencies to realize the concept of "cryptocurrency". In 1998, Wei Dai first expounded the concept of "cryptocurrency" in cypherpunks mailing list. Based on the basic concept of money, which is used to pay for goods, services and debt or any form of records in a given country or economy, bitcoin is a new form of money. Its original design is to integrate the idea of not relying on the central authority, using the principle of cryptography to control the issuance and transaction of money
in 2009, Satoshi Nakamoto published the first bitcoin specification and its proof of concept in the cryptography mailing list. At the end of 2010, Nakamoto claimed that he had transferred to other affairs and left the project. The creator of bitcoin never revealed his true identity, but left his invention to the world. Today, the origin and motivation of the invention of bitcoin is still a mysterious story
since 2010, many developers have devoted themselves to this project, and the bitcoin community has grown rapidly. Between June and July 2011, bitcoin suddenly gained media attention, leading to large-scale buying. The resulting bubble led to the continued decline in the price of bitcoin in the second half of 2011. After that, the price of bitcoin graally rose to the height of 2011
in order to regulate, protect and promote the development of bitcoin, the bitcoin foundation was established on September 27, 2012. Nowadays, with the increasing number of bitcoin users, bitcoin economy is developing rapidly
technical features
any network like bitcoin has the following basic features:
bitcoin can be transferred between any node of the network
the transaction is irreversible
the use of block chain avoids the occurrence of double consumption
the transaction will spread out in a few seconds and pass validation in 10 to 60 minutes
transaction processing and currency issuance are carried out through mining
bitcoin can be received at any time whether it is online or not<
economic rules
the whole bitcoin network jointly implements the following rules:
the total amount of bitcoin issued is about 21 million
a bitcoin can be divided into 8 decimal places, with a total of about 21 × 1014 monetary units
transaction costs are very low and most of them are free
statistics
bitcoin network has been running continuously for more than 48 months. In the past year, bitcoin's security features have attracted attention and developed significantly. As of April 2013:
the longest block chain has more than 232000 blocks
one of the largest distributed computing networks in the world, with more than 65 trillion hashes per second
there are 50000 transactions every day, with a total amount of several million US dollars
the total value of bitcoin in circulation exceeds US $1.3 billion
there is only one major security incident in the protocol, which was resolved in August 2010

well, who makes me happy to help (ChAT)

1. Bitcoin is a kind of virtual code electronic currency, with a total amount of only 21 million. There are more than 12 million bitcoins generated on the Internet through a mysterious and complex algorithm The origin should be based on the 2008 world financial crisis. A person named Nakamoto Tsung on the Internet put forward an idea: to generate e-money through a mysterious algorithm. The banks or institutions that have not issued this kind of money are completely proced through the participation of everyone on the Internet, so it is decentralized and there is no inflation; Later, in 2009, he established this algorithm and successfully generated e-money. He named it bitcoin
3. No one has issued it. Thousands of people in the world participate in this algorithm through personal computers or mining machines to generate bitcoin. The more bitcoin is calculated, the longer it takes for this algorithm to generate bitcoin
4 I didn't dig it, I just bought it. Bitcoin is just a string, which is stored in bitcoin E-wallet.
5. Tell others this string, and they can extract it into their own wallet.
6. If you want to get it, you are not recommended to dig it yourself. According to the current calculation, the computer is equipped with a 7970 graphics card, 24 hours a day, You can't dig 0.1 bitcoin in a month
so, young man, you'd better go to the bitcoin trading platform and buy one.
PS: at present, the biggest function of bitcoin is as a speculative tool, which is bigger than the futures yield. Of course, high yield is accompanied by high risk, or if you save it for 10 years, maybe the value will be 100 times or nothing. Heaven or hell, all in the minds of all.
Bitcoin is a kind of electronic cryptocurrency based on blockchain, which is decentralized, global, and does not need third-party institutions or indivials. Bitcoin was invented and founded by Nakamoto (pseudonym) on January 3, 2009, based on the peer-to-peer network without borders, using consensus initiative open source software. It is the ancestor of cryptocurrency and blockchain, and is also the cryptocurrency with the highest popularity and market value at present
generally speaking, bitcoin is a digital currency with a total amount of 21 million, which has the characteristics of decentralization, globalization, anonymity and so on, just like the Internet. Transferring bitcoin to the other side of the earth is as simple, low-cost and unlimited as sending e-mail. Bitcoin is therefore used in cross-border trade, payment, remittance and other fields
{rrrrrrr}
extended materials:
the global financial crisis broke out in 2008. On November 1, 2008, a person who called himself Nakamoto published bitcoin white paper "bitcoin: a peer-to-peer e-cash system" on the P2P foundation website, stating his new idea of e-currency bitcoin. On January 3, 2009, bitcoin Genesis block was born
compared with fiat money, bitcoin does not have a centralized issuer, but is generated by the calculation of network nodes. Anyone can participate in the manufacture of bitcoin, and it can circulate all over the world. It can be bought and sold on any computer connected to the Internet. No matter where they are, anyone can dig, buy, sell or collect bitcoin, And in the transaction process, foreigners can not identify the user's identity information
as a standardized, globalized, highly volatile, 24-hour and never-ending trading target, bitcoin is more volatile than stocks, foreign exchange, precious metals and other electronic disk targets; In terms of standardized trading, soaring history and future prospects, it is better than the physical speculation targets such as stamps and coins, garlic, Pu'er tea and Huangli wood, so it has attracted a lot of hot money to participate in the speculation
at present, the funds attracted by bitcoin as the target of speculation far exceed the funds attracted by the payment system. At least half of the price of each yuan is the value of the target of speculation
reference: network bitcoin
the concept was proposed by Satoshi Nakamoto in 2008. Then, based on the concept of openness, peer-to-peer, consensus and direct participation, combined with the working mode of open source software and block cipher in cryptography, he developed an operating system for bitcoin issuance, trading and account management on the platform of P2P peer-to-peer network and distributed database. The system enables all nodes throughout the peer-to-peer network to reach a network agreement according to their seed files, so as to ensure fairness, security and reliability in currency issuance, management and circulation. And promised that bitcoin will become "e-cash" similar to e-mail. It can avoid inflation without examination and approval, and everyone has the right to issue it; After the payment is completed, the user loses the ownership of the bitcoin. On January 3, 2009, 50 bitcoins came out
unlike traditional currencies, the operation mechanism of bitcoin does not rely on the support or credit guarantee of the central bank, the government and enterprises, but relies on the network agreement reached by the seed files in the peer-to-peer network. The decentralized and self-improvement monetary system theoretically ensures that no one, institution or government can control the total amount of bitcoin, Or create inflation. Its total amount of money graally increased at the designed rate, and the increase rate graally slowed down, and finally reached the limit of 21 million in 2140
there are many ways to use bitcoin, which can be converted into local cash or gold coins through electronic currency exchanges, service providers and indivials; It can also be used directly to purchase goods and services. With the rapid growth of indivials, organizations, businesses and enterprises receiving bitcoin payments, the exchange rate has risen thousands of times in four years. As of March 30, 2013, the total value of all issued bitcoin has exceeded 1 billion US dollars after being converted into US dollars according to the market price. Although bitcoin is currently the most widely used electronic currency, in addition to some countries have explicit provisions on virtual currency, there is no legal regulation and protection for the issuance of bitcoin in any country.
