① The fourth issue of the private blockchain conference: from barbaric growth to big waves

This article is supported by the [Blockchain Research Club] high-quality tremolo content plan, and more For more in-depth articles about blockchain, please click Blockchain Research Club

On the afternoon of March 24, 2018, the weekly "Blockchain Private Meeting" Zhengzhou Special Session was held in Zhengdong New District The industry headquarters port was held as scheduled. More than 20 blockchain investors and practitioners from traditional Internet and various fields participated in this event.

This issue of "Blockchain Private Meeting" invited Mini Investment Partner Shi Yakun. As a long-term practitioner in the field of equity crowdfunding, Shi Yakun combined his own experience in the industry to share in depth how to transform blockchain investment and some thoughts during the transformation process. Shi Yakun said: "Because of the pain points in the traditional investment field such as difficulty in financing for traditional entrepreneurs and the long withdrawal period of traditional investors' funds, the irrational explosion of ICO financing methods has led to the bubble and hype caused by it. We think deeply that more than 99% of Tokens have no investment value."

He also gave examples of financial application scenarios such as financial cross-border payments, asset securitization, and insurance policies that combine blockchain technology. Shi Yakun said frankly that the blockchain industry must go through a process of ups and downs and proper market education in order for practitioners to become more standardized. The gradual entry of traditional investors will also promote the rational development of the entire industry.

Facing the hot blockchain technology, we must actively embrace it while treating it with a cautious eye. The biggest change brought about by the characteristics of blockchain such as non-tampering and decentralization is the subversion of the entire underlying business logic. Future opportunities belong to truly valuable blockchain applications and excellent Token system designs based on the existing ecology.

③ What is blockchain

In the simplest terms, blockchain is a distributed ledger.

To understand what this means, we first have to look at its opposite: a centralized ledger. Because blockchain technology started with finance, we will also introduce it below using banks as an example.

The following is our process for using bank debit card transactions:

You can swipe your card to purchase goods in stores.

BusinessSend a statement to your bank for the agreed upon amount.

Your bank will verify that you may have authorized the purchase.

The bank sends the money to the merchant.

Finally, the bank records this information in its ledger.

There’s a lot of technology involved here, but that’s basically it. The last step is important - the bank records all transactions made by the customer. This ledger goes all the way back to the first transaction the bank made.

This ledger is kept, maintained and regulated by the bank. You can read it in your online bank account, but you can't change it. The bank has complete control. If it decides to make a change, there's nothing you can do about it.

Crucially, if hackers were able to access a bank’s ledger, that could cause a lot of problems. They can change the account balance to make it look like certain transactions never occurred, etc.

This is why distributed ledgers are so cool.

Blockchain Network Visualization

If a bank operates on a distributed ledger, each member of the bank will have a copy of the ledger, and whenever any member of the bank When they make a purchase, they tell every other member of the bank.

Each member will validate the transaction and add it to the ledger (the added records are called "blocks"). This has some important benefits, as there is no centralized authority that can manipulate records. Hackers accessing one ledger won't be a big problem because other ledgers can easily verify it.

On the other hand, it requires a lot of work. In short, the second system is blockchain (at least in financial scenarios).

As mentioned above, blockchain is a decentralized list of transactions. If I send Xiao Ming 2 Bitcoins, I send a message to everyone in the network saying "I am sending Xiao Ming 2 Bitcoins" and they all record the transaction.

The future of blockchain, how will it change our lives?

One thing that is important about blockchain is that it is a public resource and no one really owns it because everyone owns it.

Blockchain is not just science fiction. We don’t need to understand the mechanism behind this technology, but you do need to understand that it may completely change our lives in the next 20 years.

This may sound bold, but remember, 20 years ago we were browsing the Internet on Netscape, using state-of-the-art Motorola flip phones, and buying our first DVD players. At that time, if we imagined that a computer could be held in our hands and that we could buy cars, make payments, and watch movies, it would have been considered a fantasy.

While blockchain may not have the same impact as the InternetObviously, it is not as tangible as a mobile phone, but blockchain will effectively solve many troubles in daily life. Such as intermediaries cheating people, transaction delays, etc. In our current lives, middlemen are everywhere and we take them for granted as a part of life. If one day these intermediaries cease to exist, you will find that the world will become a different place.

Imagine that by 2040, blockchain may become a mature and widely used technology. When one day you can't live without the blockchain just like you can't live without the Internet now, you will be surprised to find that this decentralized accounting technology has simplified the complexity and become a part of your lifestyle

④ What are the introductory books on blockchain?

"New Economic Blueprint and Introduction"

Recommendation: This book is mainly for programmers. Combined with API programming, it tells you the principles and usage of cryptocurrency, and how to develop related software. For non-programmer readers, the first few chapters of this book are still applicable as an in-depth introduction to Bitcoin. (Download the book pdf: https://quant.la/Download)

⑤ Li Xiaolai once owned 100,000 Bitcoins, cashed out 13.5 billion and retired, what about now

Internet It has gradually developed around the world since the 1990s, and the Internet economy derived from it has given people the possibility to create wealth. Jack Ma, Ma Huateng, Liu Qiangdong, etc. did not make their fortunes by relying on the traditional real estate and energy industries, but relied on the Internet to become rich in the trend of the times. In recent years, the Internet has derived a new product - virtual currency. This product may even make you rich overnight!

⑥ What fields do these blockchain application companies mainly focus on?

There are many application scenarios for blockchain. The little secretary below will tell you about several fields that are currently widely used:

(1) Blockchain + electronic invoice

In August this year, Shenzhen The National Taxation Bureau and Tencent will jointly form a laboratory management committee and jointly release the first blockchain invoice in the country, marking that the era of blockchain invoices has arrived.

(2) Blockchain + product traceability

On Tmall’s Double 11 today, Tmall once again boasted a turnover of 213.5 billion yuan. Ant blockchain product traceability was applied to 150 million products such as diamonds, imported milk powder, beauty cosmetics, health products, Wuchang rice, and Moutai during Double Eleven, which once again demonstrated the charm of the new technology blockchain to consumers. In addition to Tmall, JD.com’s cold chain also traces the origin of JD.com’s fresh food. Many e-commerce platforms have also begun to apply blockchain in the field of product traceability.

(3) Blockchain + content
The first public chain - Ulord, users can use this platformBuild decentralized applications to share digital media content without third-party intervention. Ushare, the world's first decentralized experience value sharing platform based on the Ulord public chain, has begun public testing. Ushare gives non-head users the opportunity to advance through the ranks, eliminating the need for content middlemen. Through the pricing contract mechanism, tokens are distributed to everyone who forwards, likes, and reads, changing some of the current unreasonable interest patterns, making the entire mechanism more scientific, and the same content is distributed more widely.
(4) Blockchain + Finance

Technology giant IBM officially launched a blockchain-based cross-border payment solution at the end of August 2018 - IBM Blockchain World Wire. European banking groups, including HSBC, announced in July this year the completion of the first real-time blockchain-based cross-border financial transaction. In June 2018, Ant Financial announced that the world's "first" blockchain-based e-wallet cross-border remittance service was launched in Hong Kong, and the first remittance was completed on-site.
(5) Blockchain + Insurance

The mutual insurance that has suddenly become popular in the past two days is the innovative result of the combination of insurance and blockchain. After eliminating the high threshold of traditional commercial insurance, Mutual Insurance adopts a zero-yuan insurance purchase method to maintain fairness with the rule that one person's illness is shared by many people. Users can buy as they want and withdraw as they want. The platform only charges some management fees, which makes the district The concept of open and transparent distribution after decentralization of the blockchain is fully developed and exquisite. High transparency is achieved through blockchain technology, ensuring that there will be no insurance fraud or default.
(6) Blockchain + Intelligent Manufacturing

Alibaba, JD.com, IBM and other well-known domestic and foreign companies have begun to get involved in the blockchain + intelligent manufacturing business. IBM cooperated with Blue Ocean Camel to build a blockchain + foreign trade supply chain intelligent platform, Alibaba Cloud launched its own enterprise-level blockchain service BaaS (Blockchain as a Service), JD.com’s blockchain service platform Zhizhen Chain, etc.

(7) Blockchain + Medical

The main advantages of blockchain technology are decentralization, non-tamperability of information, and information transmission and sharing based on consensus mechanism. In all aspects, we can achieve the purpose of ensuring information security in various scenarios.

Overviewing the current development of blockchain technology and the characteristics of the medical field, we believe that the application of blockchain in the medical field can be mainly divided into the following four aspects: institutional medical information security and privacy protection; Personal medical information security and privacy protection, medical insurance and supply chain management.
