马云的区块链,马云:区块链技术演讲视频

区块链：区块链是一种分布式数据库，它使用密码学原理将数据按照链式结构进行组织存储，每一个节点都可以查看整个链条上的所有数据，从而实现数据的去中心化管理。区块链的最大特点在于，它不仅可以存储数据，还可以在数据之间建立关联，从而实现更加安全可靠的数据验证，实现数据的安全保护。

密码学：密码学是一门研究对称和不对称加密技术，以及数字签名等安全技术的学科。它的主要目的是研究如何在可能存在攻击的网络环境下，使用数字签名和加密技术来保护网络上传输的信息。密码学的最大特点是它可以有效地保护数据的安全，使传输的信息不会被破解或窃取。

去中心化：去中心化是一种分布式系统，它不依赖中心化的服务器或者中心化的组织，而是将数据分布到多个节点，由多个节点共同维护数据的完整性和一致性。去中心化的最大特点在于，它可以有效地减少单点故障，提高系统的可靠性，避免单一组织或者服务器的攻击，从而实现更加安全可靠的数据管理。

① Jack Ma talks about what blockchain is. Blockchain is not a bubble. What do you think of the blockchain white paper just released by JD.com

Blockchain is indeed a thing. So blockchain is not a bubble. Because of its high technical requirements, many people do not understand it. Those who can make reasonable use of blockchain technology will create value. If you cannot use the blockchain itself, but blindly use the word blockchain as a cover to hype, it is a bubble.
For example, real estate is a real thing, and the real estate industry is about buying and selling real things, but blind speculation will lead to a big bubble.

② Is it true that Jack Ma has officially laid out the pi coin?

Jack Ma’s views on the pi coin are as follows:
Jack Ma believes that digital currency and blockchain are very powerful. solution. He is impressed by the innovation brought by digital currency and blockchain. He has been quoted numerous times by various media outlets regarding blockchain and cryptocurrencies. Although Jack Ma is still researching and evaluating the fundamental value brought by digital currencies, he emphasized that blockchain technology as a whole is a powerful innovation.
Pi is created by a PhD team from Stanford University. A virtual currency that can be “mined” on your mobile phone. Compared with mining Bitcoin, which requires a large number of mining machines, the method of mining Pibi is very simple, and you can mine it for free with the Pibi App.

Peibi is one of the more special entities, claiming to be an encrypted digital currency that can be “mined” on your mobile phone. According to the official website of Paibi Chinese Evangelist, Paibi was created by a PhD team from Stanford University and is an opportunity for ordinary people to make money. Compared with mining Bitcoin, which requires enough mining machines, the method of mining Picoin is the simplest in the currency circle.

Some understandings of Paibi

1) Send invitations to the world to recruit blockchain talents. Five people have been hired, mainly for building the ecosystem. This is the case for other currencies. There is nothing that can be done, and there is no way to do it. For example, when connecting to a mall, the network speed of Bitcoin will freeze as soon as it is connected to the mall, and it cannot be used in real life. Pi Coin strives to complete the test on the current test network, and then go to the main network. This requires investment of time, money, and technology.

2) After ten years of development, the blockchain era has arrived and the technology has matured. Pi Coin is the first blockchain that can be applied in practice, and PNM will also be the first in the world. The blockchain mall, like Taobao, has been under construction for a year and a half and will soon be connected to Pi App. Jack Ma has become the richest man in China because of Taobao, and the founder of Pi Coin is likely to succeed because of Pi Coin.

3) The difference between Pi Coin Mall and Taobao is that Taobao uses cash to purchase goods, while PNM uses Pi coins to purchase (people who want to shop first buy Pi coins before shopping).

Also, Jack Ma made Taobao’s profits, and the profits of Pi Coin Mall are reflected in the price of Pi Coins, allowing currency holders to share dividends together.

The founder makes money by owning 20% ​​of Pi coins (clearly stipulated in the white paper), and the miners are promoters of the founder (equivalent to salesmen). How many coins we own, this is our bargaining chip (Performance).

In fact, this is quite a naturally listed stock. If you want to have equity, you can mine Pi coins now or buy Pi coins in the future.

4) The Pi Coin project team is working hard to build an ecosystem in order to achieve a 20% appreciation of the currency (more than 40 million yuan has been invested in building a mall, connecting programs, servers, etc.). We continue to work hard to have more coins. promotion.

③ What does Jack Ma think of GEC environmental coins?

Jack Ma is not very interested in environmental coins. He is more interested in the technology and area of ​​environmental coins. Blockchain. The technology of eco-friendly coins is relatively powerful, and Alibaba is also trying to make the world a cashless society.

The model of environmentally friendly coins is based on ecological environment protection, zero investment, zero risk, and high returns. It generally relies on recruiting people to join the team and pull down the development capital chain. Some industry experts pointed out that environmentally friendly coins can basically be classified as coins.

The most powerful thing about GCE is that it is completely "blockchainized" and all transactions are conducted over-the-counter. meaning is. The buying and selling of coins are peer-to-peer transactions between members. The project party does not charge anything else for selling mining machines, only GEC. He just needs to use the "mining machine" and the mechanism of inviting people offline to get more people to buy the GEC currency, and then continue to sell the currency on the sidelines.

(3) Extended reading on Jack Ma’s blockchain in 2020:

Environmental coins are also called GEC, and the introduction on the official website also mentioned, " GEC Environmental Coin" is an open source software designed and released by the World Environmental Protection Entrepreneurship Foundation. It is a P2P digital currency. The issuance quantity of "GEC Environmental Coin" is based on the constant issuance of one GEC environmental entrepreneurial coin per capita of the global population, with a total of 8 billion GEC environmental entrepreneurial coins that will never be issued.

④ How to set private privacy of Jack Ma's blockchain

As a decentralized database technology, the private privacy setting of blockchain is a very important part. Jack Ma may set up the following aspects of privacy protection on his own blockchain:
1. Identity verification: On Jack Ma’s blockchain, individual users can protect their privacy through identity verification. This means that only authenticated users can access specific information.
2. Encrypted data: Jack Ma can use blockchain technology to encrypt personal data to prevent unauthorized access. This encryption technology protects user privacy by ensuring that only authorized users can access data.
3. Anonymous transactions: An anonymous transaction function can be set up on Jack Ma’s blockchain, allowing users to conduct transactions without exposing their identities. This approach can protect user privacy to the greatest extent.
4. Restrict access rights: Jack Ma can set access limits on the blockchain to only allow specific users or organizations to access specific information. This approach protects user privacy by ensuring that only authorized people have access to sensitive information.
In short, Jack Ma can pass identity or verification, encrypt data, anonymizeUse various means such as name transactions and restricted access permissions to protect your blockchain privacy. These measures ensure that users’ data and privacy are protected to the greatest extent possible.

⑤ What’s going on with Jack Ma’s purchase of 20 billion Bitcoins?

1. Judging from the current situation circulating on the Internet, Jack Ma did not purchase 2 million Bitcoins. This is likely to be a problem in the currency circle. It is a hype by bookmakers and a fantasy and carnival by those who are optimistic about Bitcoin. It is true that I have 200 NMC coins in my hand.

2. As the richest man, Jack Ma said that he is not interested in money. This sentence really shocked everyone. I believe that every friend will borrow money from Jack Ma. People all over the country owe Jack Ma money. He is indeed a person who is not interested in money. This time Jack Ma said that he is not interested in Bitcoin, but I heard that Jack Ma has been paying attention.

3. People all over the world are reveling in this virtual electronic currency and jumping into this big trend, and Li Xiaolai is also riding on this east wind and standing on the forefront. , bought a full 100,000 Bitcoins. At that time, he was just an ordinary person, not a rich man. 100,000 Bitcoins were enough to cover his entire net worth.

4. Bitcoin, how are you doing now? Bitcoin just came out.

5. The liquidation of Bitcoin exceeded 20 billion. The reason why so much funds were liquidated was because the price of Bitcoin dropped rapidly. Just a few days ago, the largest Bitcoin holding institution sold off itself. After buying more than 9,000 shares of Bitcoin, the trader of this holding institution liquidated all the Bitcoins in his hands, causing the Bitcoin market to receive a bad signal.

6. If the price of these Bitcoins has accumulated to 120 million U.S. dollars as usual, then James is the envied "person who bought Bitcoins in a daze" but the ending is not the same. Similarly, James accidentally lost his hard drive containing 7,500 Bitcoins when he moved a few years ago.

⑥ What has Alibaba done on the blockchain

Jack Ma: I want to know what Bitcoin can bring to society

At the two sessions, Jack Ma... Oh, sorry, Comrade Ma Yun, who didn't want to wear a red hat, did not attend the two sessions.

So, let’s review Jack Ma’s remarks when evaluating Bitcoin:

In November 2017, Alibaba, Ant Financial and Xiongan Signed a strategic cooperation agreement to build the "Digital Xiongan Blockchain Implementation Platform". Currently, Ant Financial has provided blockchain application technology in the rental field in Xiongan. It can be said that Xiongan has become Alibaba’s first experimental field for the overall implementation of blockchain technology.

⑦ Why did Jack Ma personally witness the birth of the world’s first blockchain cross-border remittance

The world’s first blockchain-based e-wallet cross-border remittance service was launched in Hong Kong on June 25 Launched - Hong Kong version of Alipay AlipayHK users can send money to the Philippine wallet Gcash through blockchain technology.

Ant Financial stated that AlipayHK cooperated with Gcash to become the world's first e-wallet to use blockchain for the entire cross-border remittance link, and Standard Chartered Bank will be responsible for the end of the day. Fund clearing and foreign exchange exchange. Gcash users can spend immediately after receiving the payment. Cross-border remittances can also be received in real time like domestic transfers, 24/7, saving money and trouble, being safe and transparent. It can be said to have redefined "cross-border remittances".

⑧ Ant Group has released another blockbuster blockchain application. Can it create another "Alipay"?

Prior to this, Alibaba has also repeatedly predicted that it will release a "subversive" application today. product". So, what pain points can Trusple solve? What are the application prospects? What difficulties and obstacles does the promotion of Trusple currently face?

Another “Alipay”

“Same as Alipay’s original intention of launching secured transactions, Trusple also aims to solve the problem of transaction trust. The difference is that since blockchain technology is solving With outstanding features in trust in complex processes, Trusple better meets the needs of solving trust in international trade." said Jiang Guofei, Vice President of Ant Group and President of the Intelligent Technology Business Group.

Specifically, on the Trusple platform, when a buyer and seller generate a trade order, it is automatically uploaded to the chain and begins to circulate. The bank will automatically pay based on the payment terms agreed upon in the order, avoiding the traditional model. Sellers need to urge buyers to transfer money offline, and at the same time, they can also prevent the frequent malicious delay in payment time. Buyers can also obtain financial services such as account terms based on real orders on the chain, which greatly improves capital utilization and procurement efficiency.

For buyers and sellers, every successful transaction on Trusple is a deposit of "on-chain credit". When a company has financing needs, financial institutions can submit a verification request to the Trusple platform to determine the authenticity of the company's trade. In this way, on the one hand, it reduces the financial service risks of banks and other financial institutions, and at the same time, it also revitalizes the survival and operating capabilities of small and medium-sized enterprises.

It is understood that five banks, including BNP Paribas, Citibank, DBS Bank, Deutsche Bank and Standard Chartered Bank, have become Trusple’s first partners.

How complex is traditional trade finance business? The following is the bank's letter of credit business flow chart:

As can be seen from the above, the traditional international trade financing model is not only complex in process, but also requires high service fees from banks. If there is a blockchain trade settlement platform and a trade settlement contract is developed, the exporter directly places the advance payment in the smart contract. When the exporter's goods arrive at the destination, the system verifies that the documents are qualified and then triggers the smart contract to release the money to the exporter. Business, not only the process is simple, but the service feeWith low usage, more importantly, it can reduce the capital occupation cycle and improve capital efficiency.

"This is the case with Trusple currently launched by Ant Group, and Ant Chain also supports smart contracts." Li Lianxuan said.

To sum up, the difference between traditional cross-border trade and Trusple is centralization and decentralization. In the traditional trade model, banks serve as the center, providing transaction credit or financing facilities to buyers and sellers to ensure the smooth progress of transactions. The "credit" in this is the bank's third-party credit. As for the trust model of blockchain, its "credit" comes from the blockchain itself and does not require a third-party intermediary.

Facing two major obstacles

The launch of Trusple also fulfilled a long-cherished wish of Ali for 19 years.

As early as 2001, Alibaba B2B Company tried to use a model similar to an intermediary guarantee to solve the problem of mutual distrust between buyers and sellers in foreign trade transactions, but was unable to do so due to technical constraints at the time. Two years later, the emergence of Alipay solved the trust problem among C2C business users. However, because transactions between enterprises are much more complex than between individuals, and payment methods and logistics methods are also very different, the plan 19 years ago has been shelved to this day. Until the emergence of blockchain provides new solutions. For this reason, Alibaba calls the launch of Trusple a major launch comparable to the birth of Alipay.

It is worth noting that although Trusple has similar functions to Alipay, both are designed to solve the trust problem between different subjects, but the solution ideas are completely opposite. Trusple aims to eliminate middle links and disintermediate, while Alipay is the largest intermediary with 1 billion users. Trusple only targets B-side users in cross-border trade, so it seems to be fine with Alipay for now. So if similar products are used in domestic C2C e-commerce scenarios in the future, it will revolutionize Alipay's life.

Alibaba’s blockchain layout

Blockchain is based on the characteristics of decentralization, openness and transparency, information traceability, anti-tampering, automatic execution of smart contracts, etc., and is a natural solution to trust issues. weapon. As The Economist said: Blockchain will become a “trust machine.” Therefore, Jack Ma said that Alibaba without blockchain would "die".

Jack Ma’s words are not alarmist. Alipay, which started as an e-commerce company, has played a key role in solving the trust issue between consumers and merchants in online transactions. It can be said that without Alipay, Alibaba would not have the e-commerce empire it has today. “Over the past decade or so, we have continued to promote the construction of trust mechanisms through technology and innovation,” Ant Group said in its IPO prospectus.

To this end, as early as 2015, Alibaba established a blockchain team and began to invest in blockchain research and development. In October 2017, Ant Financial (the predecessor of Ant Group) released the “BASIC Strategy” (blockchain, artificial intelligenceIntelligence, security, Internet of Things, cloud computing). In July this year, just before Ant Group applied for listing on the Science and Technology Innovation Board, Ant Blockchain was officially upgraded to "Ant Chain". Jack Ma personally named Ant Chain, which shows its status in the Alibaba ecosystem.

Today, Alibaba has implemented more than 50 blockchain application scenarios. Ant Chain is technically able to support 1 billion account sizes and can support 1 billion daily transactions, achieving 10 transactions per second. Wanbi cross-chain information processing capabilities (PPS).

In April this year, Ant’s “Open Alliance Chain” was officially launched, fully opening up its blockchain technology and application capabilities to small and medium-sized enterprises. Subsequently, the implementation of related blockchain applications further accelerated. In July, the Ant Chain all-in-one machine was released, which can save more than 90% of blockchain deployment time for government and enterprise developers; on September 18, it was opened to the public including data security computing hardware, The privacy and security "three-piece package" of 3D contract security services and data privacy computing services; Trusple is released today.

In terms of research and development, Alibaba’s blockchain patent applications have ranked first in the world for four consecutive years, and its self-developed cross-chain technology has also been recognized as an international standard.

According to the website of the Shanghai Stock Exchange, Ant Group’s Science and Technology Innovation Board IPO has entered the “submission for registration” stage. "After listing, the most important thing for Ant Group is to invest in technology. In the future, it will focus on the research and development of five major technology areas: artificial intelligence, risk management, security, blockchain, computing and technical infrastructure." Hu Xiaoming, CEO of Ant Group, said.

⑨ Is the blockchain now in the limelight and has no future?

Blockchain is in the limelight, no, right? Blockchain technology has been developing now, and there is no such thing as saying that it has no future. Not quite right.
The current development of blockchain is still OK. Here are a few recent examples: On June 14, led by the Information Center of the High People’s Court and co-sponsored by a total of 25 units, the “Blockchain Judicial Certificate Deposit” was launched. "Application White Paper" was officially released, and blockchain technology has already achieved results in the field of judicial evidence; VISA recently launched a blockchain payment network and entered the US$125 trillion cross-border payment market; Fuzhou City also recently issued "About Acceleration Three Measures for the Development of the Blockchain Industry" to promote the implementation of blockchain technology applications.
Further further, there are blockchain electronic invoices, blockchain traceability, etc. I won’t talk about these, so there is no future for this one. Crypto Finance focuses on blockchain, you can learn more here.
