❶ What is blockchain

Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system.

1. In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable. and an unforgeable distributed ledger.

2. Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, and uses cryptography to ensure data transmission. and access security, a new distributed infrastructure and computing method that uses smart contracts composed of automated script codes to program and operate data.

(1) Extended reading on blockchain:

1. In 2008, Satoshi Nakamoto proposed the concept of blockchain for the first time. In the years that followed, it became a core component of the electronic currency Bitcoin: serving as a public ledger for all transactions.

2. By 2014, "Blockchain 2.0" became a term about a decentralized blockchain database. For this second-generation programmable blockchain, economists believe that its achievement is that “it is a programming language that allows users to write more sophisticated and intelligent protocols. Therefore, when profits reach a certain level, You can earn income from completed shipping orders or dividends from shared certificates."

3. In 2016, the Central Securities Exchange of the Russian Federation (NSD) announced a pilot project based on blockchain technology. Many institutions with regulatory powers in the music industry are beginning to use blockchain technology to establish test models for collecting royalties and managing copyrights worldwide.

4. The timestamp service and existence proof of the blockchain, the time when the first blockchain was generated and the events that were happening at that time are permanently retained.

5. The Bitcoin company BTCC launched a service "Millennium Chain" in 2015, which is the blockchain engraving service, which uses the above principles. Users can engrave text on the blockchain through this service and save it permanently.

❷ Are there any netizens who were deceived by the BTC CIMB Exchange US Index?

This HitBTC exchange has long been banned by China and its official website cannot be accessed. China has explicitly banned virtual currency platforms such as hitbtc, bittok, and bigone. The central bank officially warned such illegal activities: So, don’t take any chances. Stay away from scams. Also note the huge risk of Bittok stealing ID card information. If you have been deceived, report the case as soon as possible and report the situation to the Anti-Money Laundering Center of the People's Bank of China.
Extended information:

❸ Why is the financial industry most interested in blockchain?

On May 3 this year, the People’s Bank of China decided to establish new projects in Shanghai and other free trade zones, Suzhou Industrial Park, Kunshan and other places, as well as 27 major national banks, have launched innovative pilot projects in cross-border financing. At present, the company can borrow foreign debt through the bank's overseas branches. After the currency swap portfolio product is designed, the funds will be settled into RMB of the same term. The financing cost is the RMB loan benchmark interest rate for the same period, which eases the company's domestic financing difficulties and repays principal and interest. Lock in fixed RMB denominated principal and interest to avoid negative exchange rate risks. Cross-border financing takes 10 working days from application to disbursement. At the time when the reform pilot is being carried out, in the face of trade financing innovation in the context of blockchain, the macro-prudential management of foreign debt seems to be inadequate. From the perspective of a financial practitioner, it is urgent to study blockchain.
Of course, not only the financial industry is interested in blockchain, but other industries are also interested in blockchain. For example, a content publishing platform DECENT developed using blockchain technology has recently appeared abroad. Similar to domestic self-media platforms.

❹ What are the public blockchain chains?

Blockchains include public blockchains, joint (industry) blockchains, and private blockchains. Public chain peer-to-peer electricitySub-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.

(4) Blockchain engraving extended reading

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

1. A blockchain that is open to the entire network and has no user authorization mechanism is called Public chain;

2. Allow authorized nodes to join the network and view information according to permissions. It is often used in inter-organizational blockchains, called alliance chains or industry chains;

< p>3. All nodes in the network are in the hands of an organization, which is 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.

❺ Which blockchain media are more professional?

1. Media that specializes in blockchain, such as Golden Finance and Babbitt. These media have relatively complete content, including information, Columns, trading data, strategies, etc., can be regarded as a one-stop platform;
2. Experienced self-media platforms, such as MarsFinance, ambition finance. This type of media often starts from the Internet and has a deep understanding of Bitcoin and blockchain;
3. Blockchain public accounts opened by some financial media;
4. Blockchain opened by Internet portals Chain sectors, such as Tencent Technology and Sina Technology, have already opened blockchain sectors.

❻ Which digital currency trading platform has the largest transaction volume

Digital currency trading platforms include BTCC, Yunbi.com, Youbi, Yibi.com, and China Bitcoin.

1. BTCC

Originally founded in 2011 under the name "Bitcoin China" and headquartered in Shanghai, it is China's first Bitcoin exchange and currently operates around the world. The oldest Bitcoin exchange. After five years of growth, BTCC has deployed in digital currency exchanges, mining pools, payment gateways, user wallets, blockchain engraving and other fields, and has become a comprehensive service platform.

Note:

1. Investing in digital currencies requires a lot of skills, and you also need to be very cautious. After all, not everyone can make money by investing. If you are not careful, you may fall into the abyss, so it is very important to supplement this knowledge.

2. In the short to medium term, you should not rely too much on digital currency investments. In the worst case scenario, you should be prepared to bear the loss of your entire capital.

❼ What is the Bitcoin blockchain technology that Microsoft is interested in?

Blockchain is an important concept of Bitcoin, which is essentially decentralized. The database also serves as the underlying technology of Bitcoin. The blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a Bitcoin network transaction and is used to verify the validity of its information (anti-counterfeiting) and generate the next block.
The blockchain is public on the Internet and can be queried in every offline Bitcoin wallet data. The functionality of a Bitcoin wallet relies on confirmation with the blockchain, and a valid check is called a confirmation. Usually a transaction requires several confirmations before it can proceed. Lightweight Bitcoin wallets use online confirmations, which means no blockchain data is downloaded to device storage.
Many altcoins of Bitcoin also use the same design, but are slightly different in proof of work and algorithm. For example, using proof of stake and SCrypt, etc.

Blockchain timestamp service and proof of existence
This concept was proposed in Satoshi Nakamoto’s white paper [1], who created the first block, the “Genesis block".
On January 3, 2009, Satoshi Nakamoto, the founder of Bitcoin, left a sentence in the genesis block that can never be modified:
“The Times 03/Jan/2009 Chancellor on brink of second lout for banks (January 3, 2009, FinanceChancellor is on the verge of implementing a second round of bank bailouts). ”
It was the moment when the British Chancellor of the Exchequer Darling was forced to consider a second step to relieve the banking crisis. This sentence was the title of the front page article of The Times that day.
The time of blockchain With stamping services and proof of existence, the time when the first blockchain was created and the events that were happening at that time are permanently preserved.
The Bitcoin company BTCC launched a service "Millennium Chain" in 2015 That is, the blockchain engraving service uses the above principles. Users can engrave text on the blockchain through this service and save it permanently.
Bitcoin, Litecoin, Ritecoin, and Qianjin Card are all A digital currency based on blockchain technology.

❽ The magical blockchain allows data to be retained permanently

At the beginning of this year, the Bitcoin fever wave had not completely passed, and another " "The flood" cannot stop the fire. This is the blockchain technology that has been hotly speculated in the financial and insurance fields recently, and even has a strong presence in the stock trading and voting industries.

To talk about the hot spots that various industries have paid attention to recently, this technology must be counted as one. Let’s take a look at the data: So far, the world’s largest investment projects in 2016 are all related to blockchain, and the investment amounts have reached US$55 million and US$6,000 respectively. Ten thousand US dollars, and the largest domestic blockchain project was also announced at the end of September this year with an investment scale of more than 20 million US dollars.

First of all, normatively speaking, this is a kind of distributed data A new application model that comprehensively utilizes computer technologies such as storage, point-to-point transmission, consensus mechanisms, and encryption algorithms. As a well-known global encrypted Internet currency, Bitcoin is developed based on blockchain technology, and smart contracts on the blockchain Support makes a wider range of point-to-point transfers of digital assets other than Bitcoin a reality. It is not difficult to understand why blockchain technology has become compelling as the cornerstone of the Internet of Value.

< p>So why does the blockchain have such charm? If today’s Internet is the point-to-point transmission of information through the TCP/IP protocol, it is the Internet of information. Then, value (such as electronic currency, electronic assets, etc.) is separated from a third party for point-to-point transmission. The transfer is made possible by blockchain technology.

In layman’s terms, blockchain is a decentralized distributed accounting system. Nodes in the system do not need to trust each other. Through a unified consensus mechanism A ledger is jointly maintained, and each node has a complete data record. Blockchain transactions are connected together through cryptographic algorithms, making the entire ledger open, transparent, traceable, and non-tamperable.< /p>

Compared with traditional third-party institution credit transactions, the process of blockchain in digital payment can be described as the following diagram:
