The role of cryptopunk in bitcoin

1.

On January 3, 2009, the first batch of 50 bitcoins were g up on a small server in Finland. On May 21, 2010, the first bitcoin transaction: programmer Laszlo hanyecz bought a $25 pizza coupon with 10000 BTC. This transaction gave birth to the first fair exchange rate of bitcoin.

Satoshi Nakamoto, a self styled Japanese American, is often translated by Japanese media as the founder of bitcoin protocol and its related software bitcoin QT, but his real identity is unknown. In 2008, Nakamoto published a paper called "bitcoin: a peer-to-peer electronic cash system", which describes an electronic currency and its algorithm called "bitcoin"

In 2009, he released the first bitcoin software and officially launched the bitcoin financial system. In 2010, he graally faded out and handed over the project to other members of the bitcoin community. Nakamoto is believed to hold about one million bitcoins. These bitcoins were worth more than $1 billion at the end of 2013

since the publication of the paper, the real identity of Nakamoto has long been unknown to the outside world. Julian Assange, founder of WikiLeaks, claims that Nakamoto is a cypherpunk. In addition, some people said that "Nakamoto is an anarchist. His original intention is not to control digital cryptocurrency by a certain government or central bank, but to become a global free flowing currency that is not regulated and controlled by the government."

main entry: bitcoin history

on November 1, 2008, Nakamoto published a paper entitled "bitcoin: a point-to-point e-cash system" in the cryptography mailing list of "metzdowd. Com". This paper describes in detail how to create a decentralized electronic trading system, and this system does not need to be built on the basis of mutual trust between the two parties. Soon, on January 3, 2009, he developed the first client program to implement the bitcoin algorithm, concted the first "mining" and obtained the first batch of 50 bitcoins. This also marks the formal birth of bitcoin financial system

on December 5, 2010, ring the WikiLeaks leak of US diplomatic cables, the bitcoin community appealed to WikiLeaks to accept bitcoin donations to break the financial blockade. Nakamoto expressed his firm opposition, saying that bitcoin is still in its infancy and cannot afford conflicts and disputes. Seven days later, on December 12, he published his last article in the bitcoin forum, mentioning some minor problems in the latest version of the software. Then he did not show up and e-mail communication was graally terminated

2. On October 22, 2013, Qiao from Dongyang searched GBL company, a bitcoin trading platform, on the Internet, and recharged 90000 yuan to buy and sell bitcoin through a third-party payment. On October 26, Qiao found that the staff of the network trading platform were not online, and some normal trading proceres could not be implemented, and then reported the case to Dongyang Public Security Bureau
Dongyang Public Security Bureau of Zhejiang Province immediately started the investigation and found that Qiao was not the only one who suffered losses. Through efforts, the police of the special task force determined the identity of the manager of the GBL trading platform and implemented the pursuit in time. The first case of fraud on bitcoin trading platform in China was solved
lawyer analysis:
Zhang Yanlai, senior special researcher of China e-commerce research center and lawyer of Zhejiang Jin law firm, believes that virtual currency is not a new concept. Q-coin and online game currency have long been known by people. However, the emergence of bitcoin once again makes people realize the power of virtual currency. Compared with the traditional q-coin, the biggest feature of bitcoin is that it does not have a unified issuing agency. The generation of bitcoin completely depends on computer algorithms, and anyone can participate in the issuance of bitcoin
this makes it difficult to trace the source of bitcoin, which makes it a real virtual currency. The anonymity, cross-border and other Internet genes of bitcoin make people see a new form of currency that may circulate in the future society, so the pursuit and use of bitcoin also continued to rise in 2013. Some foreign governments have recognized the legal status of bitcoin. In China, some online stores have begun to use bitcoin for trading. Restaurants that accept "bitcoin" consumption have appeared in Beijing. The first "bitcoin" investment fund in China is also being raised. After the Ya'an earthquake, one foundation has received a total of 65 bitcoin donations, with a market price of about 50000 yuan
of course, money laundering, fraud, gambling and so on will follow. This case is a typical case of fraud under the banner of bitcoin trading. As the first case of bitcoin fraud in China, the public security organs have also concted in-depth study and understanding of the professional knowledge related to bitcoin, and finally cracked the case. On December 5, 2013, the people's Bank of China, the Ministry of instry and information technology and other five ministries and commissions issued the notice on prevention of bitcoin risk, which first made it clear that bitcoin does not have the status of legal tender, and required financial institutions and Payment institutions not to price procts or services with bitcoin. The central bank believes that there are three risks in bitcoin Trading: high speculative risk; High risk of money laundering and being used by criminals or organizations. In the future, the future of bitcoin is not clear, especially in sovereign countries, which will take a prudent and conservative attitude towards currency, which involves financial order and national security. Therefore, the public should also raise enough risk awareness.

4. In 018, the explosive development of blockchain technology was much like the Internet in 1997. I believe that the development of blockchain technology will certainly be faster than the Internet. If you don't take in some knowledge of blockchain, maybe you will fall behind an era. This article will answer several questions about bitcoin
question 1: how was bitcoin born
on November 1, 2008, a person who called himself Satoshi Nakamoto posted a statement on micro v-bq Er Wu Ba y on a secret cryptography review group (cryptopunk), stating his new idea of e-money bitcoin
question 2: how to proce bitcoin
bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to solve a complex mathematical problem with a computer to ensure the micro v-bq consistency of the bitcoin network distributed accounting system. Bitcoin generates a block every 10 minutes, which contains all the transaction information in the past 10 minutes. Whoever can work out the figures will get the right to keep accounts. After obtaining the accounting right, it will broadcast and store to the whole network. It's uncertain who gets the bookkeeping right. Of course, the stronger your computing ability is, the higher the probability of getting the bookkeeping right is. Then the bitcoin network will generate a certain amount of bitcoin as a reward to reward those who have the right to keep accounts
question 3: what are the characteristics of bitcoin
it is impossible to control the number of issues without a fully decentralized issuing institution. Bitcoin does not need a third-party organization, and it is a peer-to-peer transaction with mutual trust. The establishment of trust is no longer based on large institutions, but on cryptography and code. Bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin. The private key is needed to control bitcoin. It can be stored in any storage medium in isolation, and no one can get it except the user himself. As a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. You can pay when you know the address of the other party's bitcoin
question 4: can bitcoin be imitated
it is difficult for the cat to survive. Because bitcoin algorithm is completely open source, anyone can download the source code, modify some parameters, recompile, and create a new P2P currency. However, these counterfeit currencies are vulnerable to 51% attacks. Any indivial or organization, as long as it controls 51% of the computing power of a P2P currency network, can manipulate transactions and currency value at will, which will be a devastating blow to P2P currency. Many Shanzhai coins die in this link. The bitcoin network is robust enough. If you want to control 51% of the computing power of the bitcoin network, the number of CPUs / GPUs required will be astronomical
question 5: why is the total amount of bitcoin 21 million
when bitcoin was born in 2009, each reward was 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the bounty will be halved to 25. When the total amount reached 15.75 million (5.25 million new output, or 50% of 1050), the bounty was further halved to 12.5. And so on. According to its design principle, the total amount of bitcoin will continue to grow until it reaches 21 million more than 100 years later. However, the growth rate of bitcoin micro v-bq in the later period will be very slow. In short, bitcoin proction is halved every four years, and currently 12.5 bitcoins are proced every 10 minutes. In fact, 87.5% of bitcoin will be "g up" in the first 12 years. Moreover, 21 million is only theoretical data. In reality, e to the neglect of bitcoin in the early stage, many bitcoins were lost
question 6: what are the benefits of bitcoin miners
first of all, bitcoin will be rewarded directly after obtaining the bookkeeping right through calculation. But according to bitcoin's rules, as time goes on, the rewards will be less and less. In the future, the income will mainly come from the service charge generated by bitcoin transaction
question 7: why can't bitcoin be modified
for example, if a and B trade, a needs to pay B 100 bitcoins. But if a wants to default, he just wants to pay B a bitcoin. According to the rules of bitcoin, he has to obtain the bookkeeping right of the next 10 minute micro v-bq Er Wu Ba y before he can modify it; Similarly, he has to get another 10 minutes of bookkeeping rights, and so on. So modification is almost impossible
question 8: bitcoin transaction rate
theoretically, the bitcoin transaction rate is 7 transactions per second. In fact, bitcoin currently trades at only one transaction per second
question 9: why does bitcoin have such a strong vitality
if bitcoin is compared to a company, then it has no board of shareholders, board of directors, management, strict leadership, HR, Department Manager, staff, operating site and income. However, bitcoin has been running successfully for nine years without any problems, and its market value is hundreds of billions. The operation of the network relies on a set of mathematical algorithms, incentive mechanism and community for management and governance
question 10: what are the problems facing bitcoin
first, the transaction confirmation time is long. When bitcoin wallet is first installed with micro v-bq-y, it will consume a lot of time to download historical transaction data blocks. While bitcoin transaction, in order to confirm the accuracy of data, it will take some time to interact with P2P network, and the transaction will be completed only after the whole network is confirmed
Second, the public does not understand the principle, and the traditional financial practitioners resist. People who understand the principle know that bitcoin is not manipulated and controlled by a legal person. But the public doesn't understand, and many people can't even tell the difference between bitcoin and q-coin“ "No issuer" is the advantage of bitcoin, but in the view of traditional financial practitioners, "no issuer" currency is worthless.

5.

Bitcoin trading continues to be close to an all-time high set this month. Now its price is around $34000, up 77% from last month and 305% from last year

bitcoin was first introced as a digital currency in 2009, and was used as a digital currency on the edge of the economy for a period of time. This has become mainstream. Today, it is used almost exclusively as a "digital gold.". In other words, a scarce digital asset

to cope with novel coronavirus pneumonia, the governments of various governments have injected the central bank's money into the global market to stimulate consumption and help save the economy. p> However, the increase of money supply will erode the value of money and lead people to look for anti inflation assets to hold. In this environment, bitcoin has become a hedge against impending inflation and poor returns on other types of assets

but what function does bitcoin provide for a society where people invest so much? Why is bitcoin important? There are several possible explanations for why so many people now think bitcoin is important

this is a kind of "safe" asset. In the face of global uncertainty, buying bitcoin is a way for people to disperse their assets. Its market value can be compared to gold, another asset that glitters in difficult times

in the turmoil of global pandemic, the unconventional US presidential handover and the transfer of geopolitical power around the world, more people may think that gold and bitcoin are better alternatives to the US dollar

it is related to privacy oriented ideology. Bitcoin (and cryptocurrency in general) is not politically and ideologically neutral. It was born in the Internet age, an era deeply troubled by privacy issues

the ideological origin of bitcoin is the "cryptopunk" movement in the 1990s and the beginning of this century. According to online forum records, bitcoin is advocated as an anonymous digital currency, allowing people to interact online without being tracked by governments or companies, providing an alternative for anyone who does not trust the federal central bank system

6. Nakamoto's bitcoin white paper was first published in "cryptopunk". In a narrow sense, cryptopunk is an encrypted e-mail system
in 1992, Tim May, a senior scientist at Intel, launched the cryptopunk mailing list organization. In 1993, Eric Hughes wrote a book called the code punk manifesto. This is also the first time the word "cypherpunk" has appeared
"password punk" has about 1400 users. Topics discussed include mathematics, encryption technology, computer technology, politics and philosophy, as well as personal issues. Early members include many it elites, such as Assange, the founder of WikiLeaks, Bram Cohen, the author of BT download, Sir Tim Berners Lee, the inventor of the world wide web, Nick Saab, who proposed the concept of smart contract, and Sean Parker, one of the founders of Facebook
of course, including the inventor of bitcoin, Nakamoto Tsung. According to statistics, before the birth of bitcoin, members of cryptopunk discussed and invented 10 failed digital currencies and payment systems.
