This requires systematic study, not one or two commands. Let me share a tutorial with you to see if it helps:
PHP bitcoin development tutorial
this course is for beginners, covering the core concepts of bitcoin, such as blockchain storage, decentralized consensus mechanism, key and script, transaction and utxo, etc, At the same time, it also explains in detail how to integrate bitcoin support functions in PHP code, such as creating address, managing wallet, constructing naked transaction, etc., which is a rare bitcoin development course for PHP engineers< br />
Not long ago, the total value of bitcoin in the world exceeded one billion US dollars for the first time. For a pure virtual currency without the support of a central bank or other authority, this is a remarkable achievement. But this is also temporary: we are experiencing a bitcoin bubble, and the bursting of bubbles is only a matter of time. P>
says bubbles are doomed to break down for several reasons. The first is: because it is a bubble, no matter what charts, if it grows into the above picture, it will usher in tears at the end of a certain moment. but there is a deeper reason - bitcoin is a strange mixture of goods and money. The commodity value of bitcoin is generated by its monetary value, but as its commodity attribute becomes more and more significant, its use as currency becomes smaller
the distrust of existing financial institutions by these people, including Nakamoto, is no exception. What makes Nakamoto different is that he turns this distrust into a philosophy, which is the most important driving force behind the bitcoin project. When he introced bitcoin to the world in February 2009, Nakamoto boasted that his new currency had achieved "complete decentralization and there was no credible party". Moreover, he explained in great detail the problems that he thought should be solved urgently:
"the fundamental problem of traditional currency is the trust needed to make it work. We must trust the central bank not to devalue the currency, but the history of fiat money is full of betrayal of this trust. We have to trust that banks will save our money and transfer them electronically, but they still lend money without reservation in the rising credit bubble. We have to trust them with our privacy and trust them not to let impostors take money out of our accounts. "
Nakamoto is not paranoid: what he said here is the same as Warren; What Mr. Buffett said in his letter to shareholders in 2012 doesn't make much difference
" under the current monetary system, known investment types include money market funds, bonds, mortgage loans, bank savings, and other forms. Most of these money based investments are considered "safe.". In fact, they are among the most dangerous assets
"in the past century, these investment methods have destroyed the purchasing power of investors in many countries, even if they can continue to harvest principal and interest in a timely manner. In addition, this terrible consequence will reappear again and again. Governments determine the final value of money, and systemic factors occasionally bias them toward policies that trigger inflation. From time to time, such policies get out of control
"even in the United States, which strongly appeals for currency stability, the depreciation of the US dollar since I took over the management of Berkshire in 1965 has reached an alarming 86%. What you could buy for a dollar back then costs as much as seven dollars today. "
if you hold dollars, you have to trust the US government not to destroy your wealth. By contrast, bitcoin is built on distrust - it's designed to be a "everyone for himself" currency. In vain, because of his stupidity, he was criticized by many people in the bitcoin world: what did he think of storing his e-wallet on an Internet connected windows machine
but even when using bitcoin, people have to trust others in the end - and the objects they trust often turn out to be unreliable Mybitcoin was found to be a fraud afterwards; MT GOx encounters hackers. At present, coinlab is a popular emerging bitcoin company, but considering the benefits of hacking these companies, and the law enforcement agencies have no interest in such criminals, they always face the risk of losing customers' property
zero trust
this degree of distrust is not only a feature but also a loophole compared with the special coin - in fact, most of us are willing to outsource the task of hoarding wealth to a large trusted organization, rather than hiding $1000 under the black volcanic rock in the stone wall of the old oak root, Or a $90000 100 dollar bill wrapped in aluminum foil and hidden in the refrigerator. Managing bitcoin yourself is risky and requires high computer skills. But the trust needed to entrust one's own bitcoin to others is exactly what bitcoin aims to avoid
bitcoin's inherent suspicion of financial institutions not only distinguishes it from legal tender, but also makes it different from other virtual currencies, such as Facebook coin in the United States, Q coin in China and linden coin in the world's largest virtual game second life. All of these virtual currencies are closely monitored by the company that invented them, and are of little value outside these particular economies
some of these virtual currencies are about the same order of magnitude as bitcoin in scale, although it is difficult to compare them in the same sense for example, the annual revenue of Facebook coin is about one billion US dollars, and the market of Q coin in 2007 was so big that the people's Bank of China intervened and called on companies to stop trading with Q coin. In the recent bubble, bitcoins traded for more than $30 million a day, and most of the time they traded more than $5 million a day. The annual turnover will be about $2 billion, so long as the bubble will not burst. strong>
bitcoin is a kind of encrypted electronic currency with a fixed total amount, which is built on a global distributed network and issued without the participation of central banks and third-party institutions. The standard of bitcoin may bring greater economic benefits, predictability of price level and liquidity of resources
in a 37 page research paper, Warren E. Weber, a research consultant and visiting scholar at the Bank of Canada, and an adjunct professor at the Federal Reserve Bank of Atlanta and the University of South Carolina, speculated that in the monetary and financial system, bitcoin would be standard (called "bitcoin standard") rather than legal tender< In this study, Weber explored the similarity standard and gold standard between bitcoin. Since the consultants chose to compare bitcoin, there are many similarities between gold and bitcoin. Two of the most famous similarities include a lack of control over central banks or monetary authorities and restrictions on supply: bitcoin's algorithm allows only 21 million annual issues, and BTC gold can be in limited quantities on earth
if the bitcoin standard becomes real, there will be three different media exchanges, just like in the gold standard. Bitcoin will be the main currency. At the same time, there will be the Central Bank of the country, the issued credit currency, and the issued credit currency (paper money or deposit) commercial banks
bitcoin means different things to different people. For some, it's a future for free mobile money to unlock any central bank. For others, it's a pure digital entity of bious and bious origin. But what is bitcoin, in the most basic sense
in the most casual conversation, you can know that bitcoin, basically, digital currency. More complicated than that, of course. In fact, these are two things that are much more complicated
bitcoin has been with us since 2009, when a person (or group) with pseudonym Satoshi Nakamoto introces a platform (bitcoin, upper case) to host a digital currency (bitcoin, lower case)
bitcoin's platform is based on the "proof of concept" work and "expensive and time-consuming data generation, but can be easily verified. In the case of bitcoin, evidence works through the "mining process."“ My bitcoin, the computer must complete a complex algorithm, will work through a wide range of calculations, in exchange for some new currency. The value of this digital currency is determined by both supply and demand
a transaction is connected to a user's bitcoin address and stored in its general ledger, which is called a blockchain. If the address matches the real identity, the transaction can be traced back to the user; If not, they can't. This relative anonymity makes the platform appeal to purchase online
an important part of bitcoin's blockchain is that it is an open and distributed ledger. Through the distributed feature of this ledger, transactions on the blockchain are approved by the consensus of each member, providing security and trust without the supervision of a third party
one of the most important things to remember is to think about what bitcoin (or bitcoin) is: there is no single answer. Bitcoin is a platform, a digital classification, people can I, store and trade bitcoin, digital currency form obtained through computer algorithm and with no central authority.
Because the hacking is for financial fraud, and the famous person's Twitter account has celebrity effect, which is convenient for hackers to obtain fraud profit
according to CNN, on Wednesday (July 15, 2020) local time, a number of twitter accounts of celebrities and politicians in the United States were hacked and bitcoin fraud links were released.

business leaders including Bill Gates, Elon Musk, Jeff Bezos and Mike Blumberg shared the tweets, which were later deleted. Democratic presidential candidate Joe Biden and former President Barack Obama also tweeted the news
A spokesman for Bill Gates has confirmed that "he didn't send this tweet himself."“ We can be sure that this tweet wasn't from Bill Gates.

Sun Yuchen's sudden cancellation of lunch with Buffett is the biggest joke of the year
more than a month ago, BoChang CEO sun Yuchen used more than 30 million yuan to shoot the sky high price lunch of billionaire Warren Buffet. The lunch time is scheled for July 25. However, this morning, sun Yuchen suddenly tweeted that he canceled the lunch e to kidney stones
a twitter user suggested that sun can ask Buffett if he regrets not investing in apple, Microsoft, Amazon, Google, Netflix and Facebook earlier. Now encryption is still in its infancy, he said. If Mr. Buffett doesn't invest in bitcoin and cryptocurrency now, he may regret missing the same early technology opportunities as those above
In fact, it's a pity that Mr. Buffett didn't invest in Amazon many years ago. In May, Mr. Buffett said: "I've always been a fool and didn't buy [Amazon's stock] earlier." Earlier, he revealed that he had bought shares in AmazonSUN Yuchen: I would like to tell Warren Buffett that the whole encryption instry of Amway is excited about the coming lunch, but Sun said that it is unrealistic to think that one meal can change Warren Buffett's idea of encryption
it may be unrealistic to persuade Warren Buffett to buy cryptocurrency in just three hours. But we want to show him the latest developments in cryptocurrency and blockchain technology. "
although many people initially worried that sun Yuchen would use the lunch to promote his wave currency to Buffett, he insisted that he would present the whole encryption ecosystem to Buffett
SUN Yuchen said that not only wave field, but also encryption and blockchain, that is, the whole instry. Our goal is to decentralize the Internet

extended information:

Because some national leaders will announce major policy decisions through Twitter, such as US President trump. There is no news that Trump's Twitter account has been hacked. If hackers break into a leader's account, it may have disastrous consequences
