3. What are the more reliable public blockchain chains in China at present?

In the past, whenever we mentioned blockchain, we would always think of foreign products, such as Ethereum, but when I talk about this topic today, I will think more of China’s own blockchain technology.

At present, the mature applications of blockchain technology are more concentrated in some public chain projects, because many application projects need to be developed based on this, so I think that the current global One of the general directions for implementation is public chain projects. It is still too early to talk about maturity. After all, Bitcoin and Ethereum are still very congested. There are still many old problems that have not been solved, and many new problems will arise. The more well-known ones are Bytom, Ulord (the project is abroad, but the technology is provided by the domestic company Hunan Tianhe Guoyun Co., Ltd.), Quantum Chain, Xiaoyi NEO, Gongxinbao, etc.

Ulord is a point-to-point value transfer public chain. By building the underlying blockchain architecture and digital resource distribution protocol, it supports third-party developers to build their own applications on top of its open source protocol, and interacts with many industries. Partners work together to build a complete ecosystem of blockchain technology and applications.

Based on various rules and protocols created by Ulord, it is convenient to graft various digital resource application scenarios including text, pictures, music, videos, software, etc., and provide direct communication between information creators and consumers. docking platform. Third-party developers can build their own economic systems in Ulord, or they can focus on building various applications around Ulord, using the UlordToken in Ulord as in-system credentials.

For example, an experience sharing platform can be built on Ulord. Experience sharers price the published experiences. People who obtain experience information trade on the platform and pay the experience sharers.Each fee will be credited immediately; product promoters can post ads on Ulord, price the ads, and people who are interested in the ads and click on the ads can get a certain amount of revenue, etc. Different from the previous model where information transmission requires the help of platforms or other centralized institutions for dissemination and profit, the intermediate links are removed, and information providers and consumers are directly connected through Ulord, ensuring the maximization of the interests of the original creator.

4. What are the blockchains?

Blockchain mainly solves the trust and security issues of transactions, so it proposes four technological innovations to address this issue:
(1) Distributed ledger means that transaction accounting is completed by multiple nodes distributed in different places, and each node records a complete account, so they can all participate in supervising the legality of transactions, and can also work together to Testify for it.
Different from traditional distributed storage, the uniqueness of blockchain distributed storage is mainly reflected in two aspects: First, each node of the blockchain stores complete data according to the block chain structure. Traditional distributed storage generally divides data into multiple parts for storage according to certain rules. Second, the storage of each node in the blockchain is independent and of equal status, relying on the consensus mechanism to ensure storage consistency, while traditional distributed storage generally synchronizes data to other backup nodes through the central node. [8]
No node can record ledger data independently, thus avoiding the possibility of a single bookkeeper being controlled or bribed to record false accounts. Also because there are enough accounting nodes, theoretically speaking, the accounts will not be lost unless all nodes are destroyed, thereby ensuring the security of the accounting data.
(2) Asymmetric encryption and authorization technology. The transaction information stored on the blockchain is public, but the account identity information is highly encrypted and can only be accessed with the authorization of the data owner, thus Data security and personal privacy are guaranteed.
(3) Consensus mechanism is how all accounting nodes reach a consensus to determine the validity of a record. This is both a means of identification and a means of preventing tampering. Blockchain proposes four different consensus mechanisms, which are suitable for different application scenarios and strike a balance between efficiency and security.
The consensus mechanism of the blockchain has the characteristics of "the minority obeys the majority" and "everyone is equal". "The minority obeys the majority" does not entirely refer to the number of nodes, but can also be computing power, the number of shares, or other factors. A characteristic quantity that a computer can compare. "Everyone is equal" means that when a node meets the conditions, all nodes have the right to give priority to the consensus result, which will be directly recognized by other nodes and may eventually become the final consensus result. Taking Bitcoin as an example, it uses proof of work. Only when more than 51% of the accounting nodes in the entire network are controlled, it is possible to forge a non-existent record. When there are enough nodes joining the blockchain, this is basically impossible, thus eliminating the possibility of fraud.
(4) Smart contracts, smart contracts areBased on these trustworthy and non-tamperable data, some predefined rules and terms can be automatically executed. Take insurance as an example. If everyone's information (including medical information and risk occurrence information) is true and trustworthy, it will be easy to automate claims settlement in some standardized insurance products.

5. Blockchain is very popular in 2018. How many of them currently have national blockchain licenses? Please answer.

Currently, there are quite a few US MSB license holders. The larger ones include Huobi and Binance. The smaller domestic second- and third-tier exchanges are all licensed to operate. Licenses are also a trend in the future. Moving towards compliance, there are probably more than 20 applicants for licenses every month.

For example: MSB in the United States, Estonia, AUSTRAC in Australia

6. What are the domestic blockchain coins?

1. Bitcoin Introduction to BTC: The originator of digital currency, the most valuable virtual currency, known as the "King of Coins".
2. Introduction to Ethereum ETH: Ether is the currency name used in Ethereum and is used for payment calculations within the Ethereum Virtual Machine.
3. Introduction to Bitcoin Cash BCH: Bitcoin Cash is a fork of Bitcoin. In order to solve the problem of long Bitcoin transaction times, at 20:20 on August 1, 2017, a small number of mining machines began mining using 8M blocks, and the transaction confirmation speed was the number of Bitcoins using 1M blocks. Thousand times.
[Extended Information]
The concept of Bitcoin was first proposed by Satoshi Nakamoto on November 1, 2008, and was officially born on January 3, 2009.
The open source software designed and released based on Satoshi Nakamoto’s ideas and the P2P network built on it. Bitcoin is a P2P form of digital currency. Bitcoin’s transaction records are open and transparent. Peer-to-peer transmission means a decentralized payment system.
Unlike most currencies, Bitcoin does not rely on the issuance of a specific currency institution. It is generated through a large number of calculations based on a specific algorithm. The Bitcoin economy uses a distributed database composed of many nodes in the entire P2P network to confirm and record all Transaction behavior, and the use of cryptographic design to ensure the security of all aspects of currency circulation. The decentralized nature of P2P and the algorithm itself ensure that currency value cannot be artificially manipulated by mass production of Bitcoins. Design based on cryptography allows Bitcoin to be transferred or paid only by real owners. This also ensures the anonymity of currency ownership and circulation transactions. The total number of Bitcoins is limited. The currency system once had no more than 10.5 million in 4 years, and the total number will be permanently limited to 21 million thereafter.
In June 2021, El Salvador passed the "El Salvador Bitcoin Law", which makes Bitcoin legal tender in the country. On September 7, Bitcoin officially became El Salvador’s legal tender, becoming the first country in the world to grant legal status to digital currencies.
September 24, 2021, ChinaThe People's Bank of China issued a notice to further prevent and deal with the risks of speculation in virtual currency transactions. The notice states that virtual currencies do not have the same legal status as legal tender.
On November 10, 2021, the price of Bitcoin hit a new record high, approaching US$69,000 per coin for the first time.
In January 2022, Bitcoin continued to fall, falling below $42,000, touching a level not seen since September last year.

9. What are the public blockchain chains?

Blockchains include public blockchains, joint (industry) blockchains, and private blockchains. Public chain peer-to-peer electronic cash system: Bitcoin, smart contracts and decentralized application platform: Ethereum.

Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm.

Blockchain is an important concept of Bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of Bitcoin, it is a series of cryptographic methods related to each other. Each data block generated contains a batch of Bitcoin network transaction information, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block.

(9) What are the further readings of the nationally recognized blockchain< /p>

According to the different degrees of centralization of the blockchain network, there are three types of blockchains in different application scenarios:

1. Blocks that are open to the entire network and have no user authorization mechanism The chain is called a public chain;

2. Authorized nodes are allowed to join the network and can be checked according to permissions.Looking at information, it is often used in inter-organizational blockchains, called alliance chains or industry chains;

3. All nodes in the network are in the hands of one organization, called a private chain.

Consortium chains and private chains are also collectively called permissioned chains, and public chains are called non-permissioned chains.

Blockchain Characteristics

1. Decentralization. Blockchain technology does not rely on additional third-party management agencies or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes self-verification, transmission and management of information through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain.

2. Openness. The foundation of blockchain technology is open source. In addition to the private information of the transaction parties being encrypted, the data of the blockchain is open to everyone. Anyone can query the blockchain data and develop related applications through the public interface. Therefore, the entire System information is highly transparent.

3. Independence. Based on consensus specifications and protocols (similar to various mathematical algorithms such as the hash algorithm used by Bitcoin), the entire blockchain system does not rely on other third parties. All nodes can automatically and securely verify and exchange data within the system without the need for any human intervention.

4. Security. As long as you cannot control 51% of all data nodes, you cannot manipulate and modify network data at will. This makes the blockchain itself relatively safe and avoids subjective and artificial data changes.

5. Anonymity. Unless required by legal regulations, technically speaking, the identity information of each block node does not need to be disclosed or verified, and information transfer can be carried out anonymously.
