The deepest report: Bitmain's self-help history

The deepest report: Bitmain's self-help history
The original intention of this article is to let readers understand the causes and consequences of Bitmain internal fighting, but after writing it, I found that it is not so much internal fighting as it is a long history of self-help.
The story is very long. Let's adjust the timeline to the eve of December 17, 2018. That was one of Bitmain's most critical moments and the beginning of a series of subsequent stories.
1. Self-immolation In September 2018, Bitmain's financial department warned management that the company's cash flow has become very tight and operating costs must be reduced to allow the company to continue. The blockchain unicorn, which is valued at more than 15 billion U.S. dollars, is crippled in the run and struggling to break the corner.
In 2017, Bitmain made a profit of 1 billion US dollars In the first half of 2018, Bitmain made a profit of 1 billion US dollars Three rounds of financing, a total of 800 million US dollars Net assets should exceed 3 billion U.S. dollars In September 2018, Bitmain had tight cash flow and was on the verge of bankruptcy
A simple comparison, it is not difficult to see that Bitmain's ability to make money is incredible, and its ability to burn money is even more extreme.
How does Bitmain burn money? Do you pour cash into gasoline and burn it, or hire a lot of employees to stuff the banknotes one by one into the shredder? The actual situation is closer to the latter.
The following data can help readers quickly learn Bitmain's money burning skills.
At the beginning of 2018, the entire cryptocurrency market has entered a bear market, but Bitmain's monthly operating costs have been rising wildly. Operating costs have risen from 10 million US dollars at the beginning of the year to 50 million US dollars at the end of the year.
Large-scale expansion of the R&D team is one of the main reasons. The HR who once worked at Bitmain revealed that the company once hired more than 50 employees a day and nearly 500 employees a month. Even so, it was criticized for its slow recruitment speed. The cash consumption in this area is approximately $250 million.
Operating costs are just the tip of the iceberg. Excessive chip trial production can become a classic case of project management courses. Readers who pay attention to Cryptocurrency mining can easily find that Bitmain is still working hard to clear the inventory of Antminer S9 in 2019. As the co-CEO, Ketuan Zhan did not listen to the advice or even warnings of the Finance Department, insisting on the implementation of Excessive chip trial production, resulting in a large accumulation of inventory and tight capital turnover. Another CEO, Jihan Wu, once revealed that the loss of Excessive chip trial production to the company was approximately US$1.5 billion.
Large-scale expansion of the R&D team is one of the main reasons. The HR who once worked at Bitmain revealed that the company once hired more than 50 employees a day and nearly 500 employees a month. Even so, it was criticized for its slow recruitment speed. The cash consumption in this area is approximately $250 million.
The BM1393 chip incident is even more incredible. Chip expert Ketuan Zhan invested a lot of money on a failed chip, and finally failed again. From 2017 to 2018, Bitmain has failed Trial production of mining machine chips at least 4 times, including 16nm, 12nm and 10nm chips, of which 16nm Trial production failed twice, thus losing at least US$1.2 billion.
It is rumored that Bitmain still holds a billion U.S. dollars worth of cryptocurrency in a state of floating loss. In view of the rebound in the market in 2020, we will not comment temporarily, waiting for the correct answer from the cryptocurrency market. But the losses pointed out in the previous article are all irreversible.
2. Sole power
In September 2018, Bitmain's management realized the seriousness of the problem. It turned out that the company's money could be squandered. As a result, the management began to discuss self-help plans, and the most reasonable and effective way was obviously to lay off employees.
The probation period for newly hired employees at Bitmain is half a year, and the probationary salary is 100% of the official salary, there is no difference. Once layoffs are made, new employees who have not passed the probationary period will be the main layoff targets. The department managed by Ketuan Zhan will face large-scale layoffs. The layoff plan is strongly opposed by Ketuan Zhan. Bitmain can only temporarily abandon the layoffs and replace it with continuous reductions. For marketing and travel expenses, a budget committee was established to strictly approve every expenditure. At the same time, employee benefits, such as reimbursement of taxi expenses, breakfast supply, snacks and drinks, etc., have also been abolished, and even the tradition of giving employees 400 yuan worth of BTC/BCH every month has been stopped.
In the face of huge cash flow pressure, trivial savings is obviously of no avail. Soon, the management again discussed the layoff plan, and it has reached the point where it has to be laid off.
In December 2018, Jihan Wu began to organize all entrepreneurial veterans and business backbones to persuade Ketuan Zhan to agree to layoffs, but Ketuan Zhan still insisted not to layoffs. The persuasion process was very unsuccessful. After many meetings and intense debates, Bitmain executives were caught in a dilemma of wasting time with Ketuan Zhan.
In this process, the shortcomings of the dual CEO system began to appear, and the relationship between the two CEOs gradually deteriorated.
On the night of December 16th, Ketuan Zhan reconvened the management meeting, and more than 30 managements who were present were asked to hand over their mobile phones. At this time, Jihan Wu was on a business trip in Hong Kong and was busy with listing related work.
In the meeting, Ketuan Zhan's core content was three items:
(1) Bitmain cannot have two CEOs, only one CEO and must be Ketuan Zhan. Ketuan Zhan said that he met an old leader during a business trip. He hadn't seen each other for many years. The old leader suggested that the company can only have one CEO, and it must be him. Ketuan Zhan feels that this is a kind of fate, an opportunity given by God.
(2) Ketuan Zhan believes that the company's cash flow problems, the biggest responsibility is the inability of the financial department. To prove his point, Ketuan Zhan announced Bitmain's financial data at the meeting. In the evening, employees in Taiwan began to post messages on social media, saying that the company's capital chain was broken and the top management was split.
(3) If Ketuan Zhan is not supported, the option will be cancelled and the equity will be voided.
Hearing about this, Jihan Wu, who lives in Hong Kong, sent a WeChat message to the management who are attending the meeting.

On the afternoon of December 17, 2018, Jihan Wu returned to Beijing to negotiate with Ketuan Zhan all night, and finally reached a consensus in the early morning. Bitmain co-founder Yuesheng Ge announced the results of the negotiations. Jihan Wu and Ketuan Zhan ceased to serve as CEOs, and Haichao Wang served as CEO. Jihan Wu voluntarily backed down and Ketuan Zhan served as chairman.
The "12.17 Incident" had a very bad impact on Bitmain, especially the disclosure of Bitmain's financial status, which caused vendors to start dunning. The loan that had just been negotiated with the Bank of Beijing was cancelled the next day. Jihan Wu's resignation as CEO caused an uproar in the industry, and it became a hot topic among Cryptocurrency mining, blockchain practitioners, and investor communities. The media focused their interpretation on Bitmain's series of incidents, and generally looked down upon its ongoing Hong Kong IPO, believing that the high-level changes had already signaled the failure of the IPO in advance.
On Christmas December 24, 2018, Bitmain finally began to implement the layoff plan. This long-delayed “correct decision” was achieved after a stalemate for nearly three months. The AI ​​teams in Beijing, Singapore, Taiwan, and Shanghai have laid off more than 50% of their employees. The Israeli R&D center was closed and Shenzhen New Species Technology Co., Ltd., which had been acquired for only ten months, was dissolved, and all employees were laid off. Copernicus, Bitmain's top blockchain development team, was not spared and was wiped out in this layoff. Copernicus and some of the laid-off employees joined the new company Matrixport co-founded by Jihan Wu and Yuesheng Ge, headquartered in Singapore.
3. Past events when starting a business
After the "12.17 Incident", Jihan Wu gradually faded out of Bitmain's management affairs and turned his attention to the IPO and new company. And this is one of Jihan Wu's major mistakes, he began to let Ketuan Zhan manage Bitmain alone.
In fact, as early as 2013, Jihan Wu planted hidden dangers.
Jihan Wu, an investment banker, was the earliest translator of the Bitcoin white paper. He began to get involved in the cryptocurrency mining industry in 2012. The disappearance of Kaomao and Nangua Zhang's ticket skipping led Jihan Wu to decide to develop his own chip.
In 2013, Jihan Wu established his own mining machine company. Together with Yuesheng Ge, who was only 20 years old, he found Ketuan Zhan, an integrated circuit designer of the Chinese Academy of Sciences, to create the protagonist of this article, and later the digital Cryptocurrency mining giant, Bitmain.
Jihan Wu promised Ketuan Zhan that every time a mining machine chip was successfully developed, he would give some shares to the Ketuan Zhan team. At that time, the company founded by Ketuan Zhan was on the eve of falling apart. In order to regroup the team, Ketuan Zhan promised to share half of his shares with the team members. Unfortunately, this is just a bad check. With the rapid development of Bitmain and higher and higher valuations, the expanding Ketuan Zhan almost monopolized all the shares.
Like many startups, Bitmain encountered many difficulties in its early days, and many jobs had to be done by the boss. For example, in the chip design and production process in the second half of 2013, Bitmain was caught in a dilemma of insufficient funds. Jihan Wu personally raised funds and met with TSMC’s sales to persuade TSMC to accept the production needs of a start-up company. Jihan Wu also participated in the selection of the thermodynamic parameters of the heat sink in the Antminer S1.
In 2014, Jihan Wu discovered that this company was independently operated by Ketuan Zhan, which had huge problems. Forcing Jihan Wu to continue to participate in company management.
At that time, Bitmain's mining machine chips had just achieved a certain lead in the standard design process. Jihan Wu believes that the next step must be to develop full customization technology, but Ketuan Zhan plans to invest resources in the research of mobile payment chips.
Ketuan Zhan met a mysterious person from the Party Central Security Bureau who claimed to be able to manipulate the Party Central Committee’s decision-making process for the next generation of mobile payment cryptography standards, but this direction is likely to lead to the fact that Bitmain has just gained the lead in the mining machine market. Regained.
Jihan Wu said that as a graduate of the School of Economics, with a little memory of his high school stage and the knowledge reserve of a computer technology amateur, he retrieves various materials and papers every day, learns theories related to full customization, and goes to Ketuan Zhan conducts persuasion work there.
Fortunately, in the direction of full customization technology, Ketuan Zhan finally listened to Jihan Wu's opinion. Bitmain quickly integrated the technical experts from the United States and Russia introduced by Jihan Wu, which greatly improved the design level of chips and complete machines.
In 2015, Jihan Wu suggested that Ketuan Zhan consider the direction of artificial intelligence. But Ketuan Zhan is not here, he prefers the CPU direction. After staying asleep at night, coupled with in-depth analysis by the Bitmain investment team, Ketuan Zhan finally agreed with this direction. It is a pity that after the Tianshi Chen brothers made major breakthroughs in theory and practice, Bitmain officially invested in the relevant direction, and it was still a step behind.
In the two years from 2016 to 2017, Bitmain's business performance has achieved rapid development, becoming a unique super unicorn in the blockchain industry. According to Froth & Sullivan, in 2017, Bitmain Technology Holdings was the second largest fabless chip design company in China and the tenth largest fabless chip design company in the world, and the fourth largest fabless ASIC chip design company in the world, accounting for 74.5% of global cryptocurrency market share.
However, the huge crisis has long been buried in the early days of entrepreneurship.
Ketuan Zhan's decision on major directions revealed his weakness of extremely lack of business understanding. But every mistake he made was blocked by the company's core employees. His overconfidence in his management ability led to the gradual intensification of conflicts, and the management differences between the two founders became more serious.
4.The giant gets lost
The contradiction between the two broke out on December 17, 2018. Ketuan Zhan used extreme means to force the management to compromise with him by canceling the option, so as to achieve the goal of sole control of the company. Jihan Wu returned to Beijing from Hong Kong overnight and negotiated with Ketuan Zhan all night. In the end, the two resigned as CEO. Jihan Wu retired. Ketuan Zhan has the exclusive rights of chairman in exchange for the implementation of the layoff plan.
Jihan Wu's voluntary retreat has intensified Ketuan Zhan's management to do whatever he wants.
A Bitmain employee commented on Ketuan Zhan's management skills, summed up in two letters-SM.
After becoming the sole helm of the company, Ketuan Zhan quickly "rectified" the department in charge of Jihan Wu as the chairman of the board. He guided the sales of mining machines at the dinner, and pointed out that the sales performance is not due to the sales staff. Ability is strong, but the company provides opportunities. Take two sales leaders as examples, saying that if the company hadn't given the opportunity, they would still be losers. In addition, Ketuan Zhan also instructed the sales staff on how to toast and imparted the wine table culture and experience.
After the meal, Ketuan Zhan came to the conclusion that the quality of Bitmain sales staff was too poor, and Huawei’s blood needs to be injected to drive the company’s progress. Soon, the marketing and sales director from Huawei officially took over Bitmain, opening the era of brand premium for Antminer.
In order to further understand and guide the sales work, Ketuan Zhan asked to meet the customers with the sales staff. During the negotiation process, Ketuan Zhan had a heated discussion with customers on the issue of Chinese and Western medicine, and had also forced the sales staff to be able to ship 10,000 machines due to insufficient production capacity.
Although the requirements for sales personnel are strict, Ketuan Zhan has provided a lot of convenience for "Mainland Ark". In addition to selling mining machines at a more favorable price, Bitmain's mining machines are also hosted in Ming Wang at a higher price than the market price. Mine. It is reported that both Ketuan Zhan and Ming Wang are shareholders of Ark.
The new sales strategy of Huawei's executives has also brought very obvious changes to Bitmain. The self-righteous brand premium reduces the price-performance ratio of Antminer, causing competing products to eat away at Bitmain's market share. Later, Bitmain found that the strategy was wrong and started to cut prices, and found that the mining machine market was saturated and the purchase demand of miners had decreased.
More dangerous than the sales strategy is that the technical advantages of Antminer are being chased by competing products, and even overtaken. At the same time, the two mining pools under Bitmain also lost their first and second positions. The AI ​​business, which Jihan Wu placed high hopes and Ketuan Zhan personally supervised, became a laughing stock in the industry. Not only did it fail to make a profit, it almost brought down Bitmain.
Blindly introducing senior executives from Huawei to occupy important positions completely destroys the company's internal cultural foundation. The bureaucracy within Bitmain began to corrode from high-level employees to ordinary employees. Ketuan Zhan is not aware of this. He is still keen on recruiting Huawei employees, imitating Huawei's organizational structure and strategy, letting HR do sales and R&D personnel to do HR.
The organizational structure adjustment in October 2019 was the fuse for Ketuan Zhan to completely anger Bitmain management. This time, Ketuan Zhan completely marginalized Bitmain’s veteran employees, and suddenly promoted some of the “airborne soldiers” who had just joined the company to the position of person in charge, which caused the former person in charge to report to the new employees. The two managers who were originally equal The hierarchy becomes the subordinate relationship, the operation and development of different business lines are merged into a large department, the upward reporting process becomes more cumbersome, and the relationship between employees becomes delicate.
5. Headwind
On October 29, 2019, Jihan Wu urgently held a staff meeting. Prior to this, the legal representative of Beijing Bitmain has been changed to Jihan Wu, including the parent companies Hong Kong Bitmain and Cayman Bitmain. Jihan Wu stood in the lobby of Building 25, B1, announcing that Ketuan Zhan has been relieved of all duties. Any employee in the Bitmain Group shall no longer execute Ketuan Zhan’s instructions and participate in any meetings convened by Ketuan Zhan. If there is any violation, the company will demotion and expel the company based on the severity of the circumstances. If losses are caused to the company, the company will be held accountable.
Jihan Wu's speech is very long, which can be summarized as follows:
(1) Ketuan Zhan has been relieved of all duties. Also expelled from the original Huawei company HR Zhi Wang introduced by Ketuan Zhan at the end of 2018. Zhi Wang’s reputation on Bitmain was extremely poor and was ridiculed by employees as "nine thousand years" (In ancient China, the emperor was called "ten thousand years old", and the prince was "eight thousand years old." However, in the Ming Dynasty, there was an eunuch who caused harm to the country and the people. He called himself "nine thousand years old", meaning that he was only A little lower than the emperor's level).
(2) Ketuan Zhan's ability to control the company's option incentive plan has disappeared, and it is no longer possible to cancel employees' options at will.
(3) The organizational structure adjustment plan led by Ketuan Zhan was suspended.
(4) We are optimistic about the future of AI business, but the premise is that the main business can continue to make profits in order to support the company's continued investment in AI business.
In the speech, Jihan Wu also told employees the whole story of the "12.17 Incident" and bluntly said that the company is not in good condition. If no measures are taken, Bitmain is likely to go bankrupt in three quarters and he must come back to save the company.
At this time, Ketuan Zhan, who was on a business trip in Shenzhen, finally experienced the situation of Jihan Wu in the "12.17 Incident".
After the official return, Jihan Wu began to clearly point out the company's various problems in operation and management, and went deep into each business line to understand the situation. In the mining machine sales department meeting, employees spoke enthusiastically, reflecting on the difficulties and opinions encountered in the work, the marketing and sales director from Huawei asked with a surprised look, "Why didn't these issues be reported to me before?", and soon , The director was interviewed and "voluntarily resigned."
On November 2, 2019, Jihan Wu announced a salary increase for all employees. Bitmain’s last salary increase dates back to 2018. In principle, Bitmain has two salary increases every year.
On November 7, 2019, Ketuan Zhan spoke on social media for the first time, describing his hardship in starting a business, and condemning Jihan Wu for “stabbing a knife in the back”. At the end of the article, he also set himself a KPI for 2020, that is, the mining machine market share will reach 90%, and the AI ​​business will earn 1 billion.
But Ketuan Zhan's majestic plan did not make Bitmain employees feel emotional, but ridiculed him instead. Employees exposed that he insulted employees, advocated Chinese medicine, believed in Buddhism, drank in meetings, practiced Qigong...
However, there is less than half a year before the halving of Bitcoin production, and the cryptocurrency market shows no signs of recovery, which makes Bitmain management very anxious.
On January 6, 2020, Bitmain ushered in another round of layoffs, with a layoff ratio of about 1/3. This time the layoffs have caused many employees who have just increased their salaries to feel very grieved. On the one hand, they were looking forward to Jihan Wu's return. On the other hand, the compensation for this layoff was less than 18 years.
Ketuan Zhan, who has been unable to enter the Bitmain office area, once again spoke on social media and firmly opposed to layoffs. We do not need to lay off staff and we cannot commit suicide.
During the Spring Festival, Covid-19 broke out. Mainland China has begun to extend the Spring Festival holiday and advocate working from home. Under the chain reaction caused by Covid-19, most companies have chosen to cut salaries or even lay off employees. In the first two months of 2020, China's exports fell by 17%, U.S. stocks were broken four times in a row, Bitcoin plunged 40% in 24 hours on March 12, 2020, and crude oil futures fell by 300% on April 20, 2020...
Obviously, Jihan Wu can't predict, but this layoff seems to be the right decision again. In addition, from January to April 2020, Bitmain's revenue exceeded US$400 million amid the spread of Covid-19 and the collapse of the financial market.
6. Fight to the death
When Jihan Wu tried to get the company back on track, Ketuan Zhan was not helpless. On April 28, 2020, Ketuan Zhan finally rolled back the legal representative of Beijing Bitmain to before October 28, 2019 by repeatedly submitting administrative reconsiderations, and restored his status as a legal representative.
On the morning of May 8, 2020, a piece of news about Bitmain quickly appeared on the real-time hot search rankings, and even dominated the headlines of the day. At window 52 on the second floor of the Haidian District Government Affairs Center, when Ketuan Zhan, the legal person of Beijing Bitmain Company, was receiving the business license, a group of unidentified people snatched the business license from the industrial and commercial administrative staff. A source at the scene said that the number of unidentified people in the group was about 60 people, of which Luyao Liu was directing at the scene.
This is a skillful piece of news. It first leads readers to think that Ketuan Zhan is a victim, using 60 people to grab business licenses as the focus. The masses accused Jihan Wu of lawlessness, but ignored whether the government affairs center could have 60 personnel. As for Hong Kong Bitmain to have the right to appoint a representative to obtain a business license, this is a deeper level of thinking.
The follow-up report restored the real situation at the scene. Only more than ten people were present, and both sides were equipped with security personnel. Bitmain employees also broke the news in the circle of friends, claiming that Ketuan Zhan's bodyguard had injured Bitmain's authorized person, and said in a threatening tone, "Be careful!"
However, the subsequent plot reversal did not have much effect. Jihan Wu's reputation has been greatly affected. From a bloody soldier who rescued the company in trouble to a lawless criminal, it can be said to be a world of war. do not.
Ketuan Zhan, who succeeded in the first battle, began to counterattack Bitmain continuously. On the afternoon of June 3, 2020, Ketuan Zhan led a team to pry open the back door of the Beijing Bitmain office and formally occupied the deserted Beijing headquarters.
On June 4, 2020, Ketuan Zhan called on Bitmain employees to resume work and promised to expand the company's market value to more than US$50 billion within three to five years. After that, Ketuan Zhan began to contact employees by phone, trying to acquire the options in the hands of employees at a valuation of 4 billion US dollars.
Subsequently, Ketuan Zhan recalled Huawei's executives and issued a series of personnel appointments and removals. As of June 9, 2020, Ketuan Zhan has successively eliminated CFO Luyao Liu, and Wenguang Wang, the head of the mining center. Luyao Liu is responsible for controlling Bitmain's IPO plan. He also appointed Yanwu Ma as the HR director, Gang Ren as the head of the mining center, Yonggang Sun as the head of the supply chain, Ling Gu as the financial director, and Bin Zhu as the head of the mining machine business department. Bin Zhu is the senior executive of Huawei who was interviewed and left as mentioned in the previous article. During his tenure, he reduced Antminer’s 90% market share to 50%, and received a large number of complaints from miners. Internal employees once speculated that he might be Compete against the spies sent by the company.
In addition to recalling senior executives of Huawei, Ketuan Zhan also urged employees to return to work. They can receive a bonus of 10,000 yuan when they return to work on the same day, which is only half the next day. Ketuan Zhan showed a very kind side. Every time the elevator door is opened, Ketuan Zhan's hot gaze can be met, shaking hands, taking photos, and receiving money. As there is no personnel information, Ketuan Zhan does not know whether the person receiving the money is a Bitmain employee, and these people did not resume work the next day.
The effect of gentleness was not good, Ketuan Zhan began to force employees to return to work. Seeing that there are still very few respondents, Ketuan Zhan threatened employees through SMS, phone calls, EMS, emails and other harassment, issued multiple threats such as termination of contract, suspension of payment of social insurance, suspension of wages, and even used personal information saved by employees to form a group of employees. Domicile threats, requiring employees to perform "work handover", trying to force employees to return work computers, etc.
On June 10, 2020, the media revealed that Ketuan Zhan had controlled Bitmain's Shenzhen factory and prohibited employees from delivering normal shipments to paid customers, which caused difficulties in the operation of the Bitmain mining machine department.
On June 13, 2020, Hong Kong Bitmain, the parent company of Beijing Bitmain, issued a statement accusing Ketuan Zhan of signing a "Sales Agency Agreement" with the Ark Data Technology Co., Ltd. in which it holds shares, in an attempt to embezzle Beijing Bit's assets.
On June 17, 2020, the media revealed that Ketuan Zhan started selling 14,000 T17+ series mining machines at low prices.
On June 20, 2020, Hong Kong Bitmain officially suspended the supply of chips to the Shenzhen factory.
On July 13, 2020, in the "A Letter to All My colleagues in the Shenzhen Factory" released by Bitmain in Hong Kong, more details were added on the series of Ketuan Zhan's actions in June.
The legal person Feng Zhou of the Shenzhen plant is related to Ketuan Zhan. After being relieved of Ketuan Zhan's post, Jihan Wu flew to Shenzhen to have a long talk with Feng Zhou. Jihan Wu believes that Feng Zhou is the right person to manage the factory and help the company overcome difficulties, and decides to leave Feng Zhou to continue to manage the factory.
This wrong decision staged a story of a farmer and a snake. When Ketuan Zhan began to counterattack Bitmain, Feng Zhou was also quickly instigated and began to assist Ketuan Zhan in seizing customer machines and transferring 17,000 T17 mining machines in the warehouse. Hainan Continental Ark Data Technology Co., Ltd., which is held by Ketuan Zhan, sold them at a low price.
In order to protect the interests of customers, Jihan Wu had to make a compromise and paid the payment for some goods to a bank account controlled by Ketuan Zhan in exchange for delivery. However, after the other party received a payment of 109 million, the delivery stopped. On July 8, 2020, 5600 mining machines have been overdue.
At the same time, the factory defaulted on suppliers’ accounts payable as much as 200 million yuan. Bank acceptance bills issued by the factory, exceeding 36 million yuan, will expire on July 17, and more than 34 million yuan will expire on July 23. It is understood that Ketuan Zhan, after receiving the bank's dunning call, made it clear that he would not repay the loan, which would destroy the company and the entire group's credit in financial institutions.
7、 This is not the end
So far, the power struggle between the founders of Bitmain has been more than half a year. The office building already occupied by Ketuan Zhan is still empty, and most employees choose to work from home. Some chip developers returned to the office with the acquiescence of Jihan Wu and continued to maintain research and development to reduce the impact of infighting on technological iteration and competitiveness.
This giant ship that once stood on top of the supercomputer chip is crashing into the iceberg due to the madness of the former helm. Ketuan Zhan's madness and Jihan Wu's compromise made mistakes again and again. Bitmain tried to save himself many times, but was unable to get out of the black hole.
If the time goes back to that day in 2013, would Jihan Wu and Yuesheng Ge still choose to dial Ketuan Zhan?

The deepest report: Bitmain's self-help history

The deepest report: Bitmain's self-help history
The original intention of this article is to let readers understand the causes and consequences of Bitmain internal fighting, but after writing it, I found that it is not so much internal fighting as it is a long history of self-help.
The story is very long. Let's adjust the timeline to the eve of December 17, 2018. That was one of Bitmain's most critical moments and the beginning of a series of subsequent stories.
1. Self-immolation In September 2018, Bitmain's financial department warned management that the company's cash flow has become very tight and operating costs must be reduced to allow the company to continue. The blockchain unicorn, which is valued at more than 15 billion U.S. dollars, is crippled in the run and struggling to break the corner.
In 2017, Bitmain made a profit of 1 billion US dollars In the first half of 2018, Bitmain made a profit of 1 billion US dollars Three rounds of financing, a total of 800 million US dollars Net assets should exceed 3 billion U.S. dollars In September 2018, Bitmain had tight cash flow and was on the verge of bankruptcy
A simple comparison, it is not difficult to see that Bitmain's ability to make money is incredible, and its ability to burn money is even more extreme.
How does Bitmain burn money? Do you pour cash into gasoline and burn it, or hire a lot of employees to stuff the banknotes one by one into the shredder? The actual situation is closer to the latter.
The following data can help readers quickly learn Bitmain's money burning skills.
At the beginning of 2018, the entire cryptocurrency market has entered a bear market, but Bitmain's monthly operating costs have been rising wildly. Operating costs have risen from 10 million US dollars at the beginning of the year to 50 million US dollars at the end of the year.
Large-scale expansion of the R&D team is one of the main reasons. The HR who once worked at Bitmain revealed that the company once hired more than 50 employees a day and nearly 500 employees a month. Even so, it was criticized for its slow recruitment speed. The cash consumption in this area is approximately $250 million.
Operating costs are just the tip of the iceberg. Excessive chip trial production can become a classic case of project management courses. Readers who pay attention to Cryptocurrency mining can easily find that Bitmain is still working hard to clear the inventory of Antminer S9 in 2019. As the co-CEO, Ketuan Zhan did not listen to the advice or even warnings of the Finance Department, insisting on the implementation of Excessive chip trial production, resulting in a large accumulation of inventory and tight capital turnover. Another CEO, Jihan Wu, once revealed that the loss of Excessive chip trial production to the company was approximately US$1.5 billion.
Large-scale expansion of the R&D team is one of the main reasons. The HR who once worked at Bitmain revealed that the company once hired more than 50 employees a day and nearly 500 employees a month. Even so, it was criticized for its slow recruitment speed. The cash consumption in this area is approximately $250 million.
The BM1393 chip incident is even more incredible. Chip expert Ketuan Zhan invested a lot of money on a failed chip, and finally failed again. From 2017 to 2018, Bitmain has failed Trial production of mining machine chips at least 4 times, including 16nm, 12nm and 10nm chips, of which 16nm Trial production failed twice, thus losing at least US$1.2 billion.
It is rumored that Bitmain still holds a billion U.S. dollars worth of cryptocurrency in a state of floating loss. In view of the rebound in the market in 2020, we will not comment temporarily, waiting for the correct answer from the cryptocurrency market. But the losses pointed out in the previous article are all irreversible.
2. Sole power
In September 2018, Bitmain's management realized the seriousness of the problem. It turned out that the company's money could be squandered. As a result, the management began to discuss self-help plans, and the most reasonable and effective way was obviously to lay off employees.
The probation period for newly hired employees at Bitmain is half a year, and the probationary salary is 100% of the official salary, there is no difference. Once layoffs are made, new employees who have not passed the probationary period will be the main layoff targets. The department managed by Ketuan Zhan will face large-scale layoffs. The layoff plan is strongly opposed by Ketuan Zhan. Bitmain can only temporarily abandon the layoffs and replace it with continuous reductions. For marketing and travel expenses, a budget committee was established to strictly approve every expenditure. At the same time, employee benefits, such as reimbursement of taxi expenses, breakfast supply, snacks and drinks, etc., have also been abolished, and even the tradition of giving employees 400 yuan worth of BTC/BCH every month has been stopped.
In the face of huge cash flow pressure, trivial savings is obviously of no avail. Soon, the management again discussed the layoff plan, and it has reached the point where it has to be laid off.
In December 2018, Jihan Wu began to organize all entrepreneurial veterans and business backbones to persuade Ketuan Zhan to agree to layoffs, but Ketuan Zhan still insisted not to layoffs. The persuasion process was very unsuccessful. After many meetings and intense debates, Bitmain executives were caught in a dilemma of wasting time with Ketuan Zhan.
In this process, the shortcomings of the dual CEO system began to appear, and the relationship between the two CEOs gradually deteriorated.
On the night of December 16th, Ketuan Zhan reconvened the management meeting, and more than 30 managements who were present were asked to hand over their mobile phones. At this time, Jihan Wu was on a business trip in Hong Kong and was busy with listing related work.
In the meeting, Ketuan Zhan's core content was three items:
(1) Bitmain cannot have two CEOs, only one CEO and must be Ketuan Zhan. Ketuan Zhan said that he met an old leader during a business trip. He hadn't seen each other for many years. The old leader suggested that the company can only have one CEO, and it must be him. Ketuan Zhan feels that this is a kind of fate, an opportunity given by God.
(2) Ketuan Zhan believes that the company's cash flow problems, the biggest responsibility is the inability of the financial department. To prove his point, Ketuan Zhan announced Bitmain's financial data at the meeting. In the evening, employees in Taiwan began to post messages on social media, saying that the company's capital chain was broken and the top management was split.
(3) If Ketuan Zhan is not supported, the option will be cancelled and the equity will be voided.
Hearing about this, Jihan Wu, who lives in Hong Kong, sent a WeChat message to the management who are attending the meeting.

On the afternoon of December 17, 2018, Jihan Wu returned to Beijing to negotiate with Ketuan Zhan all night, and finally reached a consensus in the early morning. Bitmain co-founder Yuesheng Ge announced the results of the negotiations. Jihan Wu and Ketuan Zhan ceased to serve as CEOs, and Haichao Wang served as CEO. Jihan Wu voluntarily backed down and Ketuan Zhan served as chairman.
The "12.17 Incident" had a very bad impact on Bitmain, especially the disclosure of Bitmain's financial status, which caused vendors to start dunning. The loan that had just been negotiated with the Bank of Beijing was cancelled the next day. Jihan Wu's resignation as CEO caused an uproar in the industry, and it became a hot topic among Cryptocurrency mining, blockchain practitioners, and investor communities. The media focused their interpretation on Bitmain's series of incidents, and generally looked down upon its ongoing Hong Kong IPO, believing that the high-level changes had already signaled the failure of the IPO in advance.
On Christmas December 24, 2018, Bitmain finally began to implement the layoff plan. This long-delayed “correct decision” was achieved after a stalemate for nearly three months. The AI ​​teams in Beijing, Singapore, Taiwan, and Shanghai have laid off more than 50% of their employees. The Israeli R&D center was closed and Shenzhen New Species Technology Co., Ltd., which had been acquired for only ten months, was dissolved, and all employees were laid off. Copernicus, Bitmain's top blockchain development team, was not spared and was wiped out in this layoff. Copernicus and some of the laid-off employees joined the new company Matrixport co-founded by Jihan Wu and Yuesheng Ge, headquartered in Singapore.
3. Past events when starting a business
After the "12.17 Incident", Jihan Wu gradually faded out of Bitmain's management affairs and turned his attention to the IPO and new company. And this is one of Jihan Wu's major mistakes, he began to let Ketuan Zhan manage Bitmain alone.
In fact, as early as 2013, Jihan Wu planted hidden dangers.
Jihan Wu, an investment banker, was the earliest translator of the Bitcoin white paper. He began to get involved in the cryptocurrency mining industry in 2012. The disappearance of Kaomao and Nangua Zhang's ticket skipping led Jihan Wu to decide to develop his own chip.
In 2013, Jihan Wu established his own mining machine company. Together with Yuesheng Ge, who was only 20 years old, he found Ketuan Zhan, an integrated circuit designer of the Chinese Academy of Sciences, to create the protagonist of this article, and later the digital Cryptocurrency mining giant, Bitmain.
Jihan Wu promised Ketuan Zhan that every time a mining machine chip was successfully developed, he would give some shares to the Ketuan Zhan team. At that time, the company founded by Ketuan Zhan was on the eve of falling apart. In order to regroup the team, Ketuan Zhan promised to share half of his shares with the team members. Unfortunately, this is just a bad check. With the rapid development of Bitmain and higher and higher valuations, the expanding Ketuan Zhan almost monopolized all the shares.
Like many startups, Bitmain encountered many difficulties in its early days, and many jobs had to be done by the boss. For example, in the chip design and production process in the second half of 2013, Bitmain was caught in a dilemma of insufficient funds. Jihan Wu personally raised funds and met with TSMC’s sales to persuade TSMC to accept the production needs of a start-up company. Jihan Wu also participated in the selection of the thermodynamic parameters of the heat sink in the Antminer S1.
In 2014, Jihan Wu discovered that this company was independently operated by Ketuan Zhan, which had huge problems. Forcing Jihan Wu to continue to participate in company management.
At that time, Bitmain's mining machine chips had just achieved a certain lead in the standard design process. Jihan Wu believes that the next step must be to develop full customization technology, but Ketuan Zhan plans to invest resources in the research of mobile payment chips.
Ketuan Zhan met a mysterious person from the Party Central Security Bureau who claimed to be able to manipulate the Party Central Committee’s decision-making process for the next generation of mobile payment cryptography standards, but this direction is likely to lead to the fact that Bitmain has just gained the lead in the mining machine market. Regained.
Jihan Wu said that as a graduate of the School of Economics, with a little memory of his high school stage and the knowledge reserve of a computer technology amateur, he retrieves various materials and papers every day, learns theories related to full customization, and goes to Ketuan Zhan conducts persuasion work there.
Fortunately, in the direction of full customization technology, Ketuan Zhan finally listened to Jihan Wu's opinion. Bitmain quickly integrated the technical experts from the United States and Russia introduced by Jihan Wu, which greatly improved the design level of chips and complete machines.
In 2015, Jihan Wu suggested that Ketuan Zhan consider the direction of artificial intelligence. But Ketuan Zhan is not here, he prefers the CPU direction. After staying asleep at night, coupled with in-depth analysis by the Bitmain investment team, Ketuan Zhan finally agreed with this direction. It is a pity that after the Tianshi Chen brothers made major breakthroughs in theory and practice, Bitmain officially invested in the relevant direction, and it was still a step behind.
In the two years from 2016 to 2017, Bitmain's business performance has achieved rapid development, becoming a unique super unicorn in the blockchain industry. According to Froth & Sullivan, in 2017, Bitmain Technology Holdings was the second largest fabless chip design company in China and the tenth largest fabless chip design company in the world, and the fourth largest fabless ASIC chip design company in the world, accounting for 74.5% of global cryptocurrency market share.
However, the huge crisis has long been buried in the early days of entrepreneurship.
Ketuan Zhan's decision on major directions revealed his weakness of extremely lack of business understanding. But every mistake he made was blocked by the company's core employees. His overconfidence in his management ability led to the gradual intensification of conflicts, and the management differences between the two founders became more serious.
4.The giant gets lost
The contradiction between the two broke out on December 17, 2018. Ketuan Zhan used extreme means to force the management to compromise with him by canceling the option, so as to achieve the goal of sole control of the company. Jihan Wu returned to Beijing from Hong Kong overnight and negotiated with Ketuan Zhan all night. In the end, the two resigned as CEO. Jihan Wu retired. Ketuan Zhan has the exclusive rights of chairman in exchange for the implementation of the layoff plan.
Jihan Wu's voluntary retreat has intensified Ketuan Zhan's management to do whatever he wants.
A Bitmain employee commented on Ketuan Zhan's management skills, summed up in two letters-SM.
After becoming the sole helm of the company, Ketuan Zhan quickly "rectified" the department in charge of Jihan Wu as the chairman of the board. He guided the sales of mining machines at the dinner, and pointed out that the sales performance is not due to the sales staff. Ability is strong, but the company provides opportunities. Take two sales leaders as examples, saying that if the company hadn't given the opportunity, they would still be losers. In addition, Ketuan Zhan also instructed the sales staff on how to toast and imparted the wine table culture and experience.
After the meal, Ketuan Zhan came to the conclusion that the quality of Bitmain sales staff was too poor, and Huawei’s blood needs to be injected to drive the company’s progress. Soon, the marketing and sales director from Huawei officially took over Bitmain, opening the era of brand premium for Antminer.
In order to further understand and guide the sales work, Ketuan Zhan asked to meet the customers with the sales staff. During the negotiation process, Ketuan Zhan had a heated discussion with customers on the issue of Chinese and Western medicine, and had also forced the sales staff to be able to ship 10,000 machines due to insufficient production capacity.
Although the requirements for sales personnel are strict, Ketuan Zhan has provided a lot of convenience for "Mainland Ark". In addition to selling mining machines at a more favorable price, Bitmain's mining machines are also hosted in Ming Wang at a higher price than the market price. Mine. It is reported that both Ketuan Zhan and Ming Wang are shareholders of Ark.
The new sales strategy of Huawei's executives has also brought very obvious changes to Bitmain. The self-righteous brand premium reduces the price-performance ratio of Antminer, causing competing products to eat away at Bitmain's market share. Later, Bitmain found that the strategy was wrong and started to cut prices, and found that the mining machine market was saturated and the purchase demand of miners had decreased.
More dangerous than the sales strategy is that the technical advantages of Antminer are being chased by competing products, and even overtaken. At the same time, the two mining pools under Bitmain also lost their first and second positions. The AI ​​business, which Jihan Wu placed high hopes and Ketuan Zhan personally supervised, became a laughing stock in the industry. Not only did it fail to make a profit, it almost brought down Bitmain.
Blindly introducing senior executives from Huawei to occupy important positions completely destroys the company's internal cultural foundation. The bureaucracy within Bitmain began to corrode from high-level employees to ordinary employees. Ketuan Zhan is not aware of this. He is still keen on recruiting Huawei employees, imitating Huawei's organizational structure and strategy, letting HR do sales and R&D personnel to do HR.
The organizational structure adjustment in October 2019 was the fuse for Ketuan Zhan to completely anger Bitmain management. This time, Ketuan Zhan completely marginalized Bitmain’s veteran employees, and suddenly promoted some of the “airborne soldiers” who had just joined the company to the position of person in charge, which caused the former person in charge to report to the new employees. The two managers who were originally equal The hierarchy becomes the subordinate relationship, the operation and development of different business lines are merged into a large department, the upward reporting process becomes more cumbersome, and the relationship between employees becomes delicate.
5. Headwind
On October 29, 2019, Jihan Wu urgently held a staff meeting. Prior to this, the legal representative of Beijing Bitmain has been changed to Jihan Wu, including the parent companies Hong Kong Bitmain and Cayman Bitmain. Jihan Wu stood in the lobby of Building 25, B1, announcing that Ketuan Zhan has been relieved of all duties. Any employee in the Bitmain Group shall no longer execute Ketuan Zhan’s instructions and participate in any meetings convened by Ketuan Zhan. If there is any violation, the company will demotion and expel the company based on the severity of the circumstances. If losses are caused to the company, the company will be held accountable.
Jihan Wu's speech is very long, which can be summarized as follows:
(1) Ketuan Zhan has been relieved of all duties. Also expelled from the original Huawei company HR Zhi Wang introduced by Ketuan Zhan at the end of 2018. Zhi Wang’s reputation on Bitmain was extremely poor and was ridiculed by employees as "nine thousand years" (In ancient China, the emperor was called "ten thousand years old", and the prince was "eight thousand years old." However, in the Ming Dynasty, there was an eunuch who caused harm to the country and the people. He called himself "nine thousand years old", meaning that he was only A little lower than the emperor's level).
(2) Ketuan Zhan's ability to control the company's option incentive plan has disappeared, and it is no longer possible to cancel employees' options at will.
(3) The organizational structure adjustment plan led by Ketuan Zhan was suspended.
(4) We are optimistic about the future of AI business, but the premise is that the main business can continue to make profits in order to support the company's continued investment in AI business.
In the speech, Jihan Wu also told employees the whole story of the "12.17 Incident" and bluntly said that the company is not in good condition. If no measures are taken, Bitmain is likely to go bankrupt in three quarters and he must come back to save the company.
At this time, Ketuan Zhan, who was on a business trip in Shenzhen, finally experienced the situation of Jihan Wu in the "12.17 Incident".
After the official return, Jihan Wu began to clearly point out the company's various problems in operation and management, and went deep into each business line to understand the situation. In the mining machine sales department meeting, employees spoke enthusiastically, reflecting on the difficulties and opinions encountered in the work, the marketing and sales director from Huawei asked with a surprised look, "Why didn't these issues be reported to me before?", and soon , The director was interviewed and "voluntarily resigned."
On November 2, 2019, Jihan Wu announced a salary increase for all employees. Bitmain’s last salary increase dates back to 2018. In principle, Bitmain has two salary increases every year.
On November 7, 2019, Ketuan Zhan spoke on social media for the first time, describing his hardship in starting a business, and condemning Jihan Wu for “stabbing a knife in the back”. At the end of the article, he also set himself a KPI for 2020, that is, the mining machine market share will reach 90%, and the AI ​​business will earn 1 billion.
But Ketuan Zhan's majestic plan did not make Bitmain employees feel emotional, but ridiculed him instead. Employees exposed that he insulted employees, advocated Chinese medicine, believed in Buddhism, drank in meetings, practiced Qigong...
However, there is less than half a year before the halving of Bitcoin production, and the cryptocurrency market shows no signs of recovery, which makes Bitmain management very anxious.
On January 6, 2020, Bitmain ushered in another round of layoffs, with a layoff ratio of about 1/3. This time the layoffs have caused many employees who have just increased their salaries to feel very grieved. On the one hand, they were looking forward to Jihan Wu's return. On the other hand, the compensation for this layoff was less than 18 years.
Ketuan Zhan, who has been unable to enter the Bitmain office area, once again spoke on social media and firmly opposed to layoffs. We do not need to lay off staff and we cannot commit suicide.
During the Spring Festival, Covid-19 broke out. Mainland China has begun to extend the Spring Festival holiday and advocate working from home. Under the chain reaction caused by Covid-19, most companies have chosen to cut salaries or even lay off employees. In the first two months of 2020, China's exports fell by 17%, U.S. stocks were broken four times in a row, Bitcoin plunged 40% in 24 hours on March 12, 2020, and crude oil futures fell by 300% on April 20, 2020...
Obviously, Jihan Wu can't predict, but this layoff seems to be the right decision again. In addition, from January to April 2020, Bitmain's revenue exceeded US$400 million amid the spread of Covid-19 and the collapse of the financial market.
6. Fight to the death
When Jihan Wu tried to get the company back on track, Ketuan Zhan was not helpless. On April 28, 2020, Ketuan Zhan finally rolled back the legal representative of Beijing Bitmain to before October 28, 2019 by repeatedly submitting administrative reconsiderations, and restored his status as a legal representative.
On the morning of May 8, 2020, a piece of news about Bitmain quickly appeared on the real-time hot search rankings, and even dominated the headlines of the day. At window 52 on the second floor of the Haidian District Government Affairs Center, when Ketuan Zhan, the legal person of Beijing Bitmain Company, was receiving the business license, a group of unidentified people snatched the business license from the industrial and commercial administrative staff. A source at the scene said that the number of unidentified people in the group was about 60 people, of which Luyao Liu was directing at the scene.
This is a skillful piece of news. It first leads readers to think that Ketuan Zhan is a victim, using 60 people to grab business licenses as the focus. The masses accused Jihan Wu of lawlessness, but ignored whether the government affairs center could have 60 personnel. As for Hong Kong Bitmain to have the right to appoint a representative to obtain a business license, this is a deeper level of thinking.
The follow-up report restored the real situation at the scene. Only more than ten people were present, and both sides were equipped with security personnel. Bitmain employees also broke the news in the circle of friends, claiming that Ketuan Zhan's bodyguard had injured Bitmain's authorized person, and said in a threatening tone, "Be careful!"
However, the subsequent plot reversal did not have much effect. Jihan Wu's reputation has been greatly affected. From a bloody soldier who rescued the company in trouble to a lawless criminal, it can be said to be a world of war. do not.
Ketuan Zhan, who succeeded in the first battle, began to counterattack Bitmain continuously. On the afternoon of June 3, 2020, Ketuan Zhan led a team to pry open the back door of the Beijing Bitmain office and formally occupied the deserted Beijing headquarters.
On June 4, 2020, Ketuan Zhan called on Bitmain employees to resume work and promised to expand the company's market value to more than US$50 billion within three to five years. After that, Ketuan Zhan began to contact employees by phone, trying to acquire the options in the hands of employees at a valuation of 4 billion US dollars.
Subsequently, Ketuan Zhan recalled Huawei's executives and issued a series of personnel appointments and removals. As of June 9, 2020, Ketuan Zhan has successively eliminated CFO Luyao Liu, and Wenguang Wang, the head of the mining center. Luyao Liu is responsible for controlling Bitmain's IPO plan. He also appointed Yanwu Ma as the HR director, Gang Ren as the head of the mining center, Yonggang Sun as the head of the supply chain, Ling Gu as the financial director, and Bin Zhu as the head of the mining machine business department. Bin Zhu is the senior executive of Huawei who was interviewed and left as mentioned in the previous article. During his tenure, he reduced Antminer’s 90% market share to 50%, and received a large number of complaints from miners. Internal employees once speculated that he might be Compete against the spies sent by the company.
In addition to recalling senior executives of Huawei, Ketuan Zhan also urged employees to return to work. They can receive a bonus of 10,000 yuan when they return to work on the same day, which is only half the next day. Ketuan Zhan showed a very kind side. Every time the elevator door is opened, Ketuan Zhan's hot gaze can be met, shaking hands, taking photos, and receiving money. As there is no personnel information, Ketuan Zhan does not know whether the person receiving the money is a Bitmain employee, and these people did not resume work the next day.
The effect of gentleness was not good, Ketuan Zhan began to force employees to return to work. Seeing that there are still very few respondents, Ketuan Zhan threatened employees through SMS, phone calls, EMS, emails and other harassment, issued multiple threats such as termination of contract, suspension of payment of social insurance, suspension of wages, and even used personal information saved by employees to form a group of employees. Domicile threats, requiring employees to perform "work handover", trying to force employees to return work computers, etc.
On June 10, 2020, the media revealed that Ketuan Zhan had controlled Bitmain's Shenzhen factory and prohibited employees from delivering normal shipments to paid customers, which caused difficulties in the operation of the Bitmain mining machine department.
On June 13, 2020, Hong Kong Bitmain, the parent company of Beijing Bitmain, issued a statement accusing Ketuan Zhan of signing a "Sales Agency Agreement" with the Ark Data Technology Co., Ltd. in which it holds shares, in an attempt to embezzle Beijing Bit's assets.
On June 17, 2020, the media revealed that Ketuan Zhan started selling 14,000 T17+ series mining machines at low prices.
On June 20, 2020, Hong Kong Bitmain officially suspended the supply of chips to the Shenzhen factory.
On July 13, 2020, in the "A Letter to All My colleagues in the Shenzhen Factory" released by Bitmain in Hong Kong, more details were added on the series of Ketuan Zhan's actions in June.
The legal person Feng Zhou of the Shenzhen plant is related to Ketuan Zhan. After being relieved of Ketuan Zhan's post, Jihan Wu flew to Shenzhen to have a long talk with Feng Zhou. Jihan Wu believes that Feng Zhou is the right person to manage the factory and help the company overcome difficulties, and decides to leave Feng Zhou to continue to manage the factory.
This wrong decision staged a story of a farmer and a snake. When Ketuan Zhan began to counterattack Bitmain, Feng Zhou was also quickly instigated and began to assist Ketuan Zhan in seizing customer machines and transferring 17,000 T17 mining machines in the warehouse. Hainan Continental Ark Data Technology Co., Ltd., which is held by Ketuan Zhan, sold them at a low price.
In order to protect the interests of customers, Jihan Wu had to make a compromise and paid the payment for some goods to a bank account controlled by Ketuan Zhan in exchange for delivery. However, after the other party received a payment of 109 million, the delivery stopped. On July 8, 2020, 5600 mining machines have been overdue.
At the same time, the factory defaulted on suppliers’ accounts payable as much as 200 million yuan. Bank acceptance bills issued by the factory, exceeding 36 million yuan, will expire on July 17, and more than 34 million yuan will expire on July 23. It is understood that Ketuan Zhan, after receiving the bank's dunning call, made it clear that he would not repay the loan, which would destroy the company and the entire group's credit in financial institutions.
7、 This is not the end
So far, the power struggle between the founders of Bitmain has been more than half a year. The office building already occupied by Ketuan Zhan is still empty, and most employees choose to work from home. Some chip developers returned to the office with the acquiescence of Jihan Wu and continued to maintain research and development to reduce the impact of infighting on technological iteration and competitiveness.
This giant ship that once stood on top of the supercomputer chip is crashing into the iceberg due to the madness of the former helm. Ketuan Zhan's madness and Jihan Wu's compromise made mistakes again and again. Bitmain tried to save himself many times, but was unable to get out of the black hole.
If the time goes back to that day in 2013, would Jihan Wu and Yuesheng Ge still choose to dial Ketuan Zhan?

As we speak, cryptocurrency is experiencing a kind of cultural revolution

The blockchain, "an interesting organism" Vitalik, then 17, initially rejected the idea, before doing his own research on virtual currency. Soon, he wrote articles - paid in bitcoins - while studying computer science at the University of Waterloo in Canada, which eventually led him to co-found Bitcoin Magazine. In 2011, bitcoin was considered a technology so radical that many were convinced that governments would ban it, denouncing the black market that could flourish through this system. However, bitcoin survived, until it managed to negotiate at $ 19,000 stratospheric level at Christmas, despite the ensuing crash.
"For simplicity, a blockchain is a large distributed accounting register, stored on thousands of computers"
The blockchain is "an interesting organization, a new kind", says Vitalik Buterin after having walked with me the floor of the living room to cross the open space to a wooden dining table. It's an understatement, I say to myself. For simplicity, a blockchain is a large distributed accounting register, stored on thousands of computers. Thanks to the dispersion of these recordings and their security via Byzantine mathematical tools of cryptography, the blockchain is more difficult to forge than the traditional databases. Centralized pandora boxes, like your brain, are at risk of loss - and vulnerable to attack, as Equifax found from piracy of its client files. On the other hand,
Ethereum culture Vitalik Buterin's stroke of genius is to have perceived the potential behind the creation of his own blockchain, Ethereum, on which other companies of all types could rely, from payment services to games. The project quickly came to life, and everyone began to insist on the possibility of relying on this technology, from scientists to banks to entrepreneurs. At 19, Vitalik Buterin left the university to concentrate on the management of Ethereum.
We will sit down; after some awkward hesitation, he bends his bone frame in a chair. We procrastinate on food. I suggest tacos or pizzas. His associate, Thomas Greco, a developer who says he has worked with Vitalik Buterin for years, suggests Thai. Before I had time to find a menu on my phone, Greco went around the options to set his sights on the nearby Chaiya Thai Restaurant and order a boost.
Vitalik Buterin is the first to admit that he has spent a strange year 2017. The entrepreneurs backed by the Ethereum protocol started to use it to issue new chips to organize huge fundraisers in cryptocurrency for their projects, through an innovative financing mechanism called "initial coin offering" (ICO). The prices of bitcoin and ether broke records and ICOs exploded; but they have also fueled fears of a speculative runaway of the same type as tulipomania, speculation on tulip bulbs in the Netherlands, in the past. "We've created a culture where any hazardous project can raise $ 8 million, and we say 'oh yes, it's peanuts'," he says, "that's how you know. that you are in a bubble! "
"We've created a culture where any risky project can raise $ 8 million, and we say 'oh yes, it's peanuts, that's how you know you're in a bubble!'
The rise in the price of ether has made him a multimillionaire, but unlike Bitcoin fans who have tended to hang on to their assets, he was never convinced that crypto-currencies would take. When the prices seemed right, he cashed; and he "paid dearly for it financially," he notes cheerfully. He estimates that on paper, its fictitious capital, based on the value of its assets, would be three to four times larger if it had sold less cryptocurrency. After spending between $ 1 and $ 100, bitcoin jumped from less than $ 1,000 in January 2017 to more than $ 19,000 in December (the excitement has subsided, however, and has now stabilized at around 8 $ 1,000).
The young prodigy is under a lot of pressure to transform the test and move from the excitement of the blockchain to real results. He quickly explains his efforts to improve the Ethereum network, which recently became congested by the influx of users who exchange virtual chats in a game called CryptoKitties, where players raise and trade digital felines. The various tracks envisaged to increase the capacity of the blockchain bear names such as "sharding", "state channels" and "plasma". I am relieved when we move to simpler things, like his desire for immortality.
Vitalik Buterin dismayed Since childhood, Vitalik Buterin has been thinking of eternal life. When he was six, shortly after his family emigrated from Russia arrived in the United States, he came upon a book by Aubrey de Gray, a controversial British scientist with radical ideas to defeat aging. . While we sip a green tea prepared Thomas Greco while waiting for our meal, I ask him: why does he want to live forever? Vitalik Buterin is "puzzled enough to ask the question". If it is possible to live forever, then choosing not to do so is "the equivalent of jumping off a cliff," he explains. He will then reassure me: if life extension solutions have been slow in coming, they could be ready by 2060, which means it will be "probably still time for you". (I am 25.)
But then, "what would he do with eternal life?", I questioned him, imagining he might aspire to unlock the secret of unresolved mathematical puzzles. Not quite. "The most important thing is to enjoy it," he replies. During his flights, he studied languages ??he did not yet master watching French, German or Chinese films.
"If it is possible to live forever, then choosing not to do it is" the equivalent of jumping off a cliff ""
As we speak, cryptocurrency is experiencing a kind of cultural revolution. The first idealistic coders, who wanted the blockchain to transfer power from the hands of corporations and governments to those of individuals, began last year to be overtaken by intriguers motivated by the lure of a quick gain. Some ICOs have turned out to be scams. It is with consternation that Vitalik Buterin watched his blockchain be flooded by mercenaries in search of easy money.
"There are projects that have never had a soul, it's just, vroum-vroum, the price goes up," he says and typing in his long hands: "Lambo [rghini], vroum, vroum, buy, buy now! "Suddenly escaping a sharp remark about the Tron digital token, my host relaxes the atmosphere laughing loudly. Tron's market valuation reached $ 17 billion without any sign of life from a real underlying product.
Wacky valuations are, he says, "far ahead of what this field has actually done for society".
While we await delivery, the cryptocurrency markets are in full collapse. At the end of the day, the ether will have dipped by 30%. Such volatility would give traders cold sweat, but it's nothing for veterans of crypto-currencies like Vitalik Buterin - he does not even watch his phone.
Pragmatic against the system Vitalik Buterin may be disappointed by the boom, but he has welcomed the massive investment in the blockchain from the general public. The Ethereum Enterprise Alliance (EEA) was founded in 2016 to explore potential blockchain applications for the corporate world. It counts among its members BP or JPMorgan. The EEA reflects the changing mentality of the creator of Ethereum. As a teenager, he shared the general opinion of the cryptic crusader community: "the system," that is governments, banks, and big business, "is fundamentally bad, and we must resist completely and build something new "(Vitalik Buterin has a childish tic: he adds a" s "at fault to certain verbs).
But he realized that these people "are not so different from others everywhere else". Purists might see it as a betrayal of the historical roots of the blockchain; But Vitalik Buterin describes this as pragmatism, tinged with anxiety over governments with "hundreds of billions of dollars in physical weapons, many prisons ... increased surveillance of the Internet".
Vitalik Buterin a de quoi se faire du souci?: il a vu comment les premiers spécialistes du bitcoin, qui utilisaient la monnaie pour le trafic de drogue, ont fini par se faire prendre. Il évoque Ross Ulbricht, l’incroyablement jeune libertarien américain qui dirigeait Silk Road, ce marché noir du darknet spécialisé dans l’échange de substances et de marchandises illicites, tournant en grande partie grâce au bitcoin. Par sa tristement célèbre décision de recruter des tueurs à gages, Ross Ulbricht aurait fait basculer le destin du bitcoin, selon Vitalik Buterin, transformant l’histoire d’“un éventuel martyr de la désobéissance civile” en celle d’“un véritable criminel et ennemi public”. Ross Ulbricht, qui entame aujourd’hui la trentaine, a perdu l’année dernière une bataille judiciaire qui a duré cinq ans, et il risque aujourd’hui la prison à vie.
"Even if your goal is to overthrow part of the system, you need to have a vision of how it can promote human progress, and convey that vision"
"Even if your goal is to overthrow part of the system, you need to have a vision of how it can promote human progress, and convey that vision," he says. "The Lord of the Rings and Star Wars could send people a very, very misleading picture of social conflict." His reference to Hobbits and Jedi evokes childish morality, which opposes righteousness to absolute evil; Vitalik Buterin has adapted to a world without villains or heroes.
Diplomatic tour in progress So who is the most important person in his life? For once, he is at a running class. "Hmmm." There is a white. "It's hard to think of one person. Yeah. "We are saved by the arrival of the delivery.
Two women on sofas strum on laptops covered with stickers. The atmosphere is that of a student house during the revision period before the end-of-year exams. Vitalik Buterin picks plates and forks (but no knives). We unpack spicy shrimps with a pasta dish and sautéed for him, and a curry of green vegetables with wormwood and rice for me.
I ask him about his memories of Russia, a country he left at the age of six. While peeling the shrimps from his long fingers with gnawed nails, he recites a description of his hometown, Kolomna: 140,000 inhabitants, 115 km from Moscow. He went to Moscow and St Petersburg last year, met with Vladimir Putin, and spoke with Russian officials about a "cryptorouble" project. He explained how he was siding with the system these days, but I can not understand why he would help an authoritarian government. He quotes Frederick Douglass, who has been criticized for being allied with slave owners, but said: "I would unite with anyone to do good; and with no one to do evil. " He later confided to me that he encourages the Kremlin to make "the people benefit from the benefits of cryptography", but adds, resignedly, that he "does not know how far the message actually passes".
"He encourages the Kremlin to make" the people benefit from the benefits of cryptography ", but adds, resignedly, that he" does not know how far the message actually passes ""
This willingness to discuss has propelled Vitalok Buterin on a diplomatic tour, apparently for an indefinite period. During the last month, he visited four countries: Thailand, Singapore, China, the United States. He does not have a fixed address. "At this moment, I flutter everywhere," he summarizes. So where does he leave his things while he travels? He leaves the room at full speed. Baffled, I stuck an eggplant with my fork. He returns with a bright pink travel bag overflowing with t-shirts. He does not have books? He points to his Android phone.
When his fortune went from 1 million to more than 10 to 20 million dollars (for once, he fixes a little the numbers), he did not say "youpi, I'll have more stuff". "It's rather that I will not have to worry about money for a long time," he says. He donates to the Bill Gates Foundation, GiveDirectly, and Aubrey de Gray's anti-aging organization, the SENS Research Foundation.
The weight of celebrity His most important source of inspiration, he says, is the Internet. And last June, the Internet killed him: a viral rumor that he was dead plunged Ethereum's $ 4 billion market capitalization, revealing how Vitalik Buterin is intrinsically linked to the Ethereum system in the spirit traders in cryptocurrency. "It's like OK, wow, it's weird," he recalls. "My family sent me WeChat messages to ask me if it was okay."
I notice dark circles under his piercing blue eyes. Despite all his public appearances, he struggles to become famous.
"Last year, it came to a point where [celebrity] has become more embarrassing than positive," he says. He remembers a man chasing him on a plane and across an airport, trying to talk to him.
This position of power, is it something he desired? "No," he answers quickly, without hesitation. So, how could this happen? "Hmmm. Ethereum has grown. "He lowers his head as if I have scolded him. "It turned out that Ethereum has evolved without other figures as important as me emerging, I guess."
"Last June, the Internet killed him: a viral rumor that he was dead plunged Ethereum's market capitalization by $ 4 billion, revealing how Vitalik Buterin is intrinsically linked to the Ethereum system."
Vitalik Buterin seems depressed. To try to relax the atmosphere, I ask him where he would like to be in five years. "I have no idea," he sighs. "I do not usually plan more than three months in advance, let alone five years." It is clear that Ethereum started as a project, not a career plan. He ridicules bitcoin millionaires who surfed the crypto-tsunami wave until they hoarded a fortune, boasting about it as an investment feat.
"It's Russian roulette, and everyone who won the lottery seems to have the impression that they deserved it because they would be smarter," said Vitalik Buterin. He imitates an enthusiastic "bull", having bet on bitcoin: "I was loyal and I was virtuous and I stood firm and so I deserve to have my five villas and 23 lambos!" We laugh.
After making just a bite of shrimp, he begins to pick up crumbs with his index finger and describes his recent wanderings in a dilapidated neighborhood in China. He makes a fixation on "shabby grocery stores, with five-year-olds helping mom and dad rearrange water bottles." These meetings reminded him that "these are the people to whom you can really be useful".
Facebook Marketplace in the United States soon available with crypto currency? The uses of a Facebook cryptocurrency could be numerous. One thinks of a use of the corner on the Facebook Marketplace, this home platform launched in August 2017 and which competes with Le Bon Coin; in the United States maybe first and then all over the world. The advantage of no longer backing transactions on a fiduciary currency would be a simplification of international trade. But remember that Facebook is also WhatsApp, Instagram or Oculus and a cryptocurrency on Facebook social network could also decline on its multiple subsidiaries.
Although Facebook, like Google and Twitter posted a rather hostile position with regard to virtual currencies by prohibiting the advertising of crypto-currencies on its network, the deal seems to have changed. Unless, as many commentators had predicted at the time, the Facebook decision was actually motivated by the launch of a house cryptocurrency that will not have to compete with other tokens. What totally upset the cryptocurrency sector when the FaceCoin out!
What is certain is that this project should not succeed in the immediate future. Indeed, last February David Marcus had said in an interview that Facebook had not planned to integrate cryptocurrency in its applications soon. At issue: the technical difficulties crypto-currencies currently face: "payments using virtual currencies are currently very expensive, very slow," said David Marcus, pointing out that when all these problems would be resolved, " maybe we'll do something.

ELI5: bitcoin mining (xpost in ELI5)

Ok so I’ve seen several places where bitcoin has been explained, but there is one thing about it that always seems kinda glossed over: mining. I know there have been other explanations on here but I’d like to throw in mine too. It seems either explanations are either too simple, saying that miners "solve a difficult math problem" or are too arcane, talking about such-and-such hash function this, algebraically that etc. So hopefully this will be helpful if you were like me and were trying to wrap your head around the concept of mining bitcoins. I’ll address the basics of how they are mined, what keeps them mined at a limited rate, and who sets the difficulty for this "mathematical problem". I’m writing this to be kind of a "hands on" approach so you can kinda see what’s going on. For all you technical people out there, please bear with me as i will be simplifying some concepts...
Ok, first, i think the biggest misconception about mining bitcoins is that the analogy about computers solving difficult problems, while correct, is misleading. Mining is more akin to rolling dice than solving problems.
To understand mining, one needs to understand what a hash function is. Put simple, a hash function takes an input and creates a seemingly random output, however the output is consistent every time you perform the function on a given input, and it is very difficult to determine an input, given only the output. What i want you to do right now is open up a calculator on your computer. In the calculator, take the square root of 3. You should get 1.73205080756887729352744634150. Now take the digits from the 5th place after the decimal all the way to the 10th place after the decimal. As you can see, its 508075. Now try that with another prime number, let’s say 11. sqrt(11) = 3.3166247903553998491149327366707, and the digits in place 5 through 10 are: 247903. This is basically a very simple (and weak) hash function. For any given prime number (in this case it has to be prime), we can find a number (the 6 digit resultant output) that seems to have nothing to do with it, but can be consistently calculated easily. If i were to give you the output 512754, what would be the input? If i didn’t tell you it was 13, you would have to resort to trial and error to find it.
For the next example, we are going to use a different hash function, the SHA-256. This is the actual function used for mining bitcoin. This function doesn’t need a prime number as its input; it can use basically any text. Ok now for some hands-on. Open chrome/safari/IE/Firefox and search Google/Bing/yahoo for "sha-256 calculator" and click on probably the first hit. For me, it was http://www.xorbin.com/tools/sha256-hash-calculator but any result should work and yield the same results.
There should be a text box. In that text box type "pay me, joe, 25 bitcoins. 000001" without the quotes, then press calculate. You should get 4699f0e443b7… as your result. Now, anyone can do that. Why on earth would anyone give you bitcoins for that? There’s nothing special about that output, it’s just a seemingly random string of numbers, right? Well how can we prove that you have done work, and therefore give "scarcity" to the output? We can agree to only accept outputs that start with a zero! Ok so now what i want you to do are change that last digit in your input (the 000001) and make it a 000002, and then recalculate. Keep going until your output starts with a zero. I got all the way to 000013. Now my output is 0ac980.... tada! Scarcity, and therefore, "proof of work". I would just like to add here that obviously a bitcoin miner doesn’t use the words “pay me, joe…”, it uses computer code, and an receiving address, not a person’s name, but the gist is the same. Other data is also included in this hash input such as transactions, a timestamp, and, importantly, a reference to the previous solution so you can’t just reuse solutions. Transactions are a topic for another day.
Since no one knows how to take a given output to create a given input with this hash function, we can prove that it took some work to get an output that starts with a 0. "well that’s dumb" you may say "computers can calculate stuff like that super-duper fast," you continue, "why, I’ll be rich within a day or so." Easy slugger, bitcoin hash outputs need to start with about 14 zeroes at the time of this writing in order to be accepted by the network as a solution. When your computer finally does manage to find a solution, it sends the hash input that it found to other computers, which quickly check the hash output, and if it does, in fact, start with the required number of zeroes, it is relayed to other computers and so on, so forth, until it is propagated around the entire network. All computers now honor your address with 25 shiny new bitcoins. Also, no one can change “joe” to “bob” because that would change the entire hash output.
That number of zeroes that the output has to start with is known as the "difficulty." right now, the entire network of miners makes about 30 trillion(!) attempts at this solution every SECOND. You can see the "hash rate" at sites like bitcoincharts.com. A solution (which yields 25 bitcoins to the finder) is found approximately every 10 minutes.
Ok, so where’s that jerk that’s making the difficulty so high!? I’d like to give him a piece of my mind! The difficulty is set by all bitcoin users. On an individual basis, (not by some consensus) each bitcoin user calculates the difficulty of solutions that they will accept and relay to other nodes. That doesn’t mean that different nodes will accept different difficulties. Each one calculates (and arrives at the exact same conclusion) the difficulty by checking the timestamp on the most recent solution it has received, and comparing it with the timestamp on a solution that came 2016 solutions before the current one. (There are 2016 10-minute periods in 2 weeks) The amount of time that has elapsed SHOULD be two weeks, because solutions ought to be coming in about every 10 minutes. If the elapsed time is, say, one week, it means the difficulty is too easy, and solutions are pouring in too fast, and the new difficulty will be TWICE that of the previous difficulty so that the next solutions pour in once about every 10 minutes, and 2016 solutions will occur over the next 2 week period.
And there you have it, predictable scarcity. The one quality that a unit of currency or barter MUST have to make it worth something, or at least a placeholder for something that is worth something.
