❶ What are the three major public chains of blockchain?

The three major public chains of blockchain refer to BTC, ETH, and ADA
Blockchain public chains are also It is called a blockchain public chain. The public chain means that anyone can read the data in the system at any time. Public chains are often completely decentralized. This feature makes it impossible for everyone and institutions to Control or tamper with data on the chain.
Extended information:
Blockchain is a term in the field of information technology. In essence, it is a shared database, and the data or information stored in it has the characteristics of "unforgeable", "full traces left", "traceable", "open and transparent" and "collectively maintained". Based on these characteristics, blockchain technology has laid a solid foundation of "trust" and created a reliable "cooperation" mechanism, which has broad application prospects.
Types
1. Public Blockchains
Public Block Chains means: any individual or group in the world can send transactions, and the transactions can be effectively confirmed by the blockchain , anyone can participate in its consensus process. The public blockchain is the earliest blockchain and the most widely used blockchain. The virtual digital currencies of all major bitcoins series are based on the public blockchain. There is only one blockchain corresponding to this currency in the world. .
2. Consortium (Industry) Blockchains
Industry Blockchains (Consortium Block Chains): Multiple preselected nodes are designated within a certain group as bookkeepers, and each block is generated by all preselected nodes. Nodes jointly decide (pre-selected nodes participate in the consensus process), other access nodes can participate in transactions, but do not participate in the accounting process (it is essentially still managed accounting, but becomes distributed accounting, how many pre-selected nodes, how to decide each The bookkeeper of the block becomes the main risk point of the blockchain), and anyone else can conduct limited queries through the open API of the blockchain.
3. Private Blockchain
Private Block Chains: Only use the general ledger technology of the blockchain for accounting. It can be a company or an individual, and the blockchain can be used exclusively With write permissions, this chain is not much different from other distributed storage solutions. Traditional finance is trying to experiment with private blockchains, while applications of public blockchains such as Bitcoin have been industrialized, and application products of private blockchains are still being explored.

❷ How much does a bottle of this Guojiao 1573 38 degree wine cost?

800 yuan per bottle.

Guojiao 1573

Guojiao 1573 is a liquor brand under Luzhou Laojiao and is also a brand for Chinese liquor appreciation. Standard wine. Guojiao 1573 was built in 1573 AD.

Guojiao 1573 is one of the Luzhou Laojiao series wines. It originated from the "National Treasure Cellars" during the Wanli Period of the Ming Dynasty (i.e. 1573 AD) and uses distilled liquor.Due to the brewing process, the wine is colorless and transparent, has an elegant cellar aroma, is sweet and refreshing, soft and harmonious, has a long tail aroma, and has a typical style.

History and development

On September 9, 1999, 1999 bottles of 1999ml Guojiao 1573 were specially brewed. Among them, No. 0003 and No. 0002 were privately owned by Macau Chief Executive Ho Hau Wah and Hong Kong Chief Executive Tung Chee Hwa respectively. Collect it, and its number 0001 will be designated as a gift to the first chief executive after Taiwan returns to the mainland.

In November 1996, the State Council designated Luzhou Laojiao’s exquisite cellars with a cellar age of more than 400 years as a national key cultural relics protection unit for protection. This cellar complex was first built during the Wanli period of the Ming Dynasty and has been continuously used to this day. It has become a living cultural relic witness to the signing standard of Chinese liquor culture and the development of (solid-state) distilled wine brewing technology, so it is called the "National Cellar".

Birth

In 1996, relevant departments ordered the Luzhou Ming Dynasty wine cellar owned by Luzhou Laojiao Co., Ltd. to be protected as a national key cultural relic.

In 1573 of the Gregorian calendar, the first year of Wanli in the Ming Dynasty, the 13th emperor of the Ming Dynasty, Zhu Yijun (Shenzong), ascended the throne and changed the Yuan Dynasty. According to chronicles, Luzhou Laojiao began to form a large-scale wine cellar group.

In 447 years (1573-2020 AD), these cellars were fermented year after year, which was of great significance and use value in brewing technology - China invented (solid state) distilled wine technology Finally, the taste quality basis of distilled spirits.

It mainly relies on fermentation pits, which is also the difference in the brewing process between Chinese distilled liquor and Wisky (whiskey) and Brandy (brandy). The maturity and aroma of Chinese distilled liquor mainly depend on the pits. The fermentation process is completed.

❹ Tchain: A new generation of underlying public chain created by Silicon Valley elites

Tchain is a very creative underlying public chain that integrates a number of innovative technologies and is determined to create a truly capable The underlying public chain that implements decentralized commercial-grade applications. The founding team of Tchain are all industry veterans with many years of experience. It can be said that Tchain is a star project born with a golden key.

Tchain’s mission is to accelerate the world’s transformation into a commercial application-oriented blockchain network. Team members are unanimously optimistic about the future of the decentralized world and are making unremitting efforts to accelerate the transformation of centralized business to blockchain. The goal of the Tchain team is ambitious. To achieve this goal, the team has formulated a detailed development plan so that investors can clearly see the future of Tchain, the ambition of Tchain, and the value of Tchain.

As early as July, the Tchain Research Foundation UBL (Universal Blockchain Ltd) was established in the United States with a registered capital of US$100 million. Rory, the core founder of Tchain, serves as a member of the board of directors. The foundation is mainly responsible for the development of Tchain public chain technology, global docking of Tchain ecological resources, etc., laying the foundation for the official launch of the project.Do a good job of paving the way.

In mid-August, the Tchain team hired American Legal Counsel as a special legal team for the public chain to be responsible for the compliance of public chain operations and prepare legal documents for subsequent operations: including ecological investment and financing, and external cooperation. , legal documents for currency listing on first-line exchanges, etc., to protect Tchain’s global ecological layout.

In September, the Tchain team officially released the Tchain white paper in Chinese and English, which elaborated on Tchain’s core technologies such as multi-layer side chains, resource isolation, and one chain, one scenario, etc., which attracted great attention from industry insiders. , many well-known media rushed to report it. At the same time, the founding team attended multiple offline exchange meetings, shared the goals, vision and motivation of creating Tchain with fans, and announced the official launch of the Tchain project.

In October, the internal beta versions of Wallet 0.1 and Testnet 0.1 were released at the same time.

❻ How to explain the underlying public chain of LikeLib in an easy-to-understand manner

“LikeLib realizes the decentralization of the system by establishing decentralized autonomous organizations (DCOs). Reconstruction and development. The LikeLib main chain handles the main application business model, and the side chain adapts to diversified and multi-matching application scenario access. It uses parallel computing to expand the blockchain to millions of users and millions of times per second. Transactions become possible, improving the efficiency of smart business development. LikeLib is a blockchain truly developed for commercial applications.

From the perspective of blockchain technology application, LikeLib is not just a cross-chain implementation A blockchain project for transactions and multi-asset interoperability, it is a complete blockchain development platform. While LikeLib realizes cross-chain transaction functions, it is also a blockchain network that can operate independently: it contains native coins and supports smart contracts, and has privacy protection controls for smart contract token transactions. Any developer can develop financial applications that meet needs on LikeLib based on application scenarios."

These two paragraphs are from LikeLib. The words in the white paper, simply translated, mean: First, LikeLib is a blockchain truly developed for commercial applications. Second, any developer, even an ordinary developer who has a little understanding of smart contracts, can develop a DApp.

Business applications are ever-changing and technology upgrades are changing with each passing day. The LikeLib community recognizes the fact that technology upgrades and business application logic are unpredictable, and has absorbed the modular thinking of Linux kernel design to develop the LikeLib micro-system. At the core, LikeLib design follows the principle of "everything is a module" and uses modularity to support technology updates and application adaptation.

As for which industries the public chain can bring changes to in the future, taking LikeLib as an example, perhaps we can look ahead:

(1) Public chain + information security: using blockchain technology Realize users’ rights to directly own and control their personal data, improve people’s lives and enhance privacy security by providing digital identities.

(2) Public chain + commodity traceability: Use blockchain technology to make data of various commodities into blocks, and then generate private keys according to relevant algorithms to prevent tampering, and then use timestamps, etc. The method forms a chain, which is exactly in line with the process production model of the commodity market. Commodity circulation itself is process-based. Raw materials are produced from the place of origin through a series of processes, and information is also produced fromFrom the information about the place of origin to the information about the processing, from raw materials to processing to circulation and finally to sales, it is a chronological process. The information in the blockchain is also sorted in chronological order and can be traced in real time. Yes, the two fit perfectly.

(3) Public chain + securities: With the application of blockchain technology in the securities industry, it is possible to establish a financial market that does not require the credit endorsement of a central institution and realize point-to-point securities transactions in a decentralized system. At the same time, utilizing the automated smart contracts and programmability features of blockchain can eliminate the transaction process on the stock exchange, improve transaction efficiency, and effectively reduce costs.

Of course, LikeLib's applications are by no means limited to these fields, but also include payment, insurance, credit reporting, supply chain, finance, etc. With the underlying public chain, it can provide solutions to the trust problems that currently exist in various industries, thereby promoting the implementation of project applications.

❼ What are the three major public chains of blockchain?

Public chain, short for public chain, means that anyone in the world can read it, anyone can send transactions and transactions can Obtain valid confirmation of a blockchain in which anyone can participate in the consensus process.

1. The top three public chains in the world
BTC, ETH, and EOS (by market capitalization) are three heavyweight products, representing Blockchain 1.0, Blockchain 2.0 and Blockchain 3.0 respectively. Three stage.

1. Bitcoin BTC (Blockchain 1.0)
Bitcoin has emerged as a new type of digital currency and global payment network since its birth in 2009. BTC is also the most successful and mature application of blockchain. , now in many situations, BTC is much more famous than blockchain.

2. Ethereum ETH (Blockchain 2.0)
In layman’s terms, Ethereum is an open source platform digital currency and blockchain platform that provides developers with a platform to build and publish applications on the blockchain. . Ethereum can program, decentralize, guarantee, trade anything, vote domain names, financial exchanges, crowdfunding, company management contracts and most agreements, intellectual property, and hardware-integrated smart assets, etc.

3. Yuzu EOS (Blockchain 3.0)
EOS appears as an enterprise-level blockchain operating system based on Bitcoin and Ethereum, which is easier to use and more powerful than the former. EOS provides all application developers with many functions such as database account permission settings, execution scheduling authentication, and network communication.

2. The world's three major exchange public chains: Huobi Chain, Binance Chain, and OKEx Chain OKChain
1. Developed by Huobi Chain, the world's largest trading platform, Huobi Chain is An independently innovative supervised blockchain operating system for the financial field, based on blockchain global asset digitization and financial market infrastructure. At the same time, based on injecting unified value into the long-term value of HT,For overall consideration, HT will serve as the only underlying token of the Huobi public chain.
2. Developed by Binance, the world's second largest trading platform, Binance Chain started early in application and is currently mainly circulated on DEX and asset chains. Binance Chain is a digital asset creation and exchange platform, with BNB as the main chain token
3. Developed by OKEx, the world's third largest trading platform, OKChain is a more scalable, high-transaction processing capability trading and smart contract platform, OKChain Developed based on Cosmos-SDK, the consensus uses DPOS. OKB is the underlying token of the OKEx ecosystem.

❽ What is the public chain in the blockchain?

The public chain is also called the "public chain", which means that anyone in the world can enter the system at any time to read Fetch data, send transactions, and compete for accounting on the blockchain. Public blockchains are generally considered "completely decentralized" because no individual or institution can control or tamper with the reading and writing of data in it. In terms of application, public blockchain chains mainly include Bitcoin, Ethereum, Hyperledger, most altcoins, and smart contracts. The ancestor of the public blockchain chain is the Bitcoin blockchain, which has the following characteristics ：

1. The code is open source

The code is uploaded to github, and everyone can download the complete blockchain data and accept the test of the public.

2. Complete decentralization

Anyone can become a node, every node is public, everyone can participate in the calculation of the blockchain, and any node can It is not permanent, but periodic, and no center is mandatory for nodes. Anyone can read and send transactions, and transactions can be effectively confirmed on the blockchain, and anyone can participate in the consensus process. The consensus process determines which block can be added to the blockchain, and its exact current state. Everyone can receive financial rewards, proportional to their contribution in the consensus process. These public chains are often considered to be “completely decentralized.”

3. Develop decentralized applications

Program developers can easily develop decentralized applications through this public chain. Public chains can protect users’ rights and interests from the influence of program developers.

❾ What kind of operating system is needed for blockchain?

People often use the Internet for comparison when studying blockchain. There are three major operating systems in the Internet field. : windows, Android, IOS, windows occupy a large share of the PC side, and Android and IOS occupy the mobile side. So what is the operating system of blockchain? Based on the current public chains: ETH, EOS, AE NEO and other public chains, who will be Windows Android or IOS in the blockchain field? Today’s focus is to take a look at EOS!

Invested communityAn investment principle that I believe in: investing in projects means investing in people, especially serially successful entrepreneurs who are the favorites of investors. BM is the creator of the two projects BTS and STEEM. BTS STEEM has been running very stably to this day. Li Xiaolai, a big man in the investment industry The teacher commented on BM this way: BM is the only person in the world who can successfully build two blockchain projects. He will invest in no matter what projects BM does. This fully reflects the principle that investment is investment. At the beginning of 2017, BM announced that it had joined Block. One as the chief technology officer to develop the EOS project. So on June 1, 2017, the world's one-year-long ICO was launched, setting a new record in the world.

EOS is a blockchain underlying public chain system being developed by Block.One. It aims to solve the problem of low performance, poor security, high development difficulty and over-reliance on handling fees of existing blockchain applications. The problem. When EOS completes its system goals, any team can develop the required Dapps on EOS at a relatively fast speed. These Dapp applications can be easily used by ordinary people without any fees, and it is even difficult to feel the benefits of using them. It is a blockchain application. The high performance of EOS (100W+TPS, 100W packaging and accounting can be performed within 1 second) can carry a large number of Dapp applications, so it is foreseeable that EOS may be a super unicorn that can incubate many unicorn companies. Beast platform.

In layman's terms, EOS is a foundation with a nearly infinite area. This foundation is solid, exquisite, and beautifully designed. It also provides various "building blocks" on top of the foundation. Developers (Dapp applications) The team) can use these "building blocks" to easily build the commercial buildings, cinemas, office buildings or cabins in their design drafts. If users want to enter these real estate projects for consumption, they do not need to buy tickets first, but can enjoy various landscape.

Briefly summarize several features of EOS

1. Support millions of users

2. Free to use

3. Easy upgrade and BUG recovery

4. Low latency

5. Serial capability

6. Parallel capability

When people complain that Bitcoin transfers take too long, and even raising a cat on Ethereum is stuck to death, then will the arrival of Yuzu make you happy?
Global decentralized blockchain spirit; 2017-2018 EOS dominated the blockchain field, with the longest ICO time and the largest amount of funds. Lao Mao also commented: The second half of 2018 will be EOS’s home ground

ETH relies on smart contracts Functions and ICO chips, it was once in the leading and second position, with the highest currency price exceeding 10,000. When comparing ETH and EOS horizontally and vertically on the same platform, EOS has a million-level tps powerful transaction function and free use of core killing weapons that puts ETH to shame. EOS can We will wait and see whether it will replace ETH as the operating system of blockchain projects!
