⑴ What is the concept of blockchain

Blockchain is a digital ledger that can be jointly recorded. It will record all transactions that have occurred and have been unanimously approved by the system. It's equivalent to the whole family mobilization method of accounting. You are accounting, and your father and mother are also accounting. They can all see the general ledger, but the information that has been saved cannot be tampered with.

The concept of blockchain was first proposed by Satoshi Nakamoto in 2008. Blockchain then became a core component of the electronic currency Bitcoin, serving as the public ledger for all transactions. By leveraging peer-to-peer networks and distributed timestamp servers, blockchain databases can be managed autonomously.

(1) Who is the blockchain? Extended reading proposed in 2008:

Types of blockchain

1. Public blocks Chain

Any individual or group in the world can send transactions, and the transactions can be effectively confirmed by the blockchain, and 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 pre-selected nodes are designated within a certain group as bookkeepers. The generation of a block is jointly decided by all pre-selected nodes (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, pre-selected The number of nodes and how to determine the bookkeeper of each block has become the main risk point of the blockchain). Anyone else can make limited queries through the open API of the blockchain.

3. Private blockchain

Only use the general ledger technology of the blockchain for accounting. It can be a company or an individual who has exclusive access to the writing of the blockchain. With access permissions, this chain is not much different from other distributed storage solutions.

⑵ Who proposed the idea of ​​blockchain

Satoshi Nakamoto (English: Satoshi Nakamoto), who claims to be Japanese-American, is often translated as Philosophy of Nakamoto in Japanese media. Man is the creator of the Bitcoin protocol and its associated software Bitcoin-Qt, but his true identity is unknown. Satoshi Nakamoto published a paper titled "Bitcoin: A Peer-to-Peer Electronic Cash System" in 2008, describing a method he called "Bitcoin." "Coin" electronic currency and its algorithm. In 2009, he released the first Bitcoin software and officially launched the Bitcoin financial system. In 2010, he gradually faded away and handed the project over to other members of the Bitcoin community. Satoshi Nakamoto is believed to beHolds approximately 1 million Bitcoins.

⑶ What does blockchain mean?

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.

(3) Who proposed the blockchain in 2008? Extended reading:

1. In 2008, Satoshi Nakamoto proposed the blockchain for the first time. The concept of the blockchain, in subsequent years, became a core component of the electronic currency Bitcoin: as a public ledger of 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.

⑷ What are the prospects of blockchain?

The application of blockchain has extended to many fields such as medical health, education, charity, social management, and finance. The biggest advantage of blockchain is that it truly completes the construction of credit in an anonymous society, bringing new opportunities to many fields, thus making various innovative applications possible. . The current blockchain is equivalent to the Internet 20 years ago. It is in its preliminary stage. In the future, it will definitely become a major part of the social economy and be used to benefit the people and society. Please wait and see!
Blockchain uses a distributed database to identify, disseminate and record informationAn intelligent peer-to-peer network, also known as the Internet of Value. The concept of blockchain was first proposed by Satoshi Nakamoto in his paper "Bitcoin: A Peer-to-Peer Electronic Cash System" published on the Bitcoin Forum in late 2008.
It is a chain data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be an untamperable and unforgeable distributed ledger.
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 the security of data transmission and access. A new distributed infrastructure and computing method that uses smart contracts composed of automated script codes to program and manipulate data.
Blockchain Investment
Blockchain investment is indeed one of the hottest investment methods in today’s society. Although blockchain seems to have just started, as such a novel existence, it It is indeed very unique. Many people don’t know what blockchain is. They only know that blockchain mining can make money, so they follow it in a fog. But to achieve a truly safe investment, I suggest that everyone still Understand it first, prepare well before taking action, and don’t fight an unprepared battle.
Blockchain technology does have huge room for growth in the future. Many people believe that it will be able to subvert many existing industries in the future. This is very important. This is the source of all your confidence. If you If you don’t recognize the value of blockchain from the bottom of your heart, then you are likely to be affected by some negative remarks and even doubt the entire industry, which will affect your entire decision-making and judgment.
If you just want to play casually or test the water, the chance of success is very small.
Once you are determined, be prepared and spend all your precious energy on research. When investing, you must do your homework! Never invest money without knowing what the project is about.
Finally, the blockchain is a new industry after all. It is currently in a mixed situation, and of course there are scammers. Therefore, when we invest, we must be careful and do not accept what others say. Bright eyes.
In addition, I still have to say that investment is risky, so you must be cautious!

Blockchain application fields

1. Financial field

Blockchain has potential huge application value in financial fields such as international exchange, letters of credit, equity registration and stock exchanges. The application of blockchain technology in the financial industry can eliminate the need for third-party intermediaries and achieve direct point-to-point connection, thereby greatly reducing costs and quickly completing transaction payments.

2. Internet of Things and Logistics Fields

Blockchain can also be naturally combined in the Internet of Things and logistics fields. Through blockchain, logistics costs can be reduced, the production and delivery process of items can be traced, and the efficiency of supply chain management can be improved. This field is considered a promising application direction of blockchain.

3. Public welfare field

The data stored on the blockchain is highly reliable and cannot be tampered with, so it is naturally suitable for use in social welfare scenarios. Relevant information in the public welfare process, such as donation projects, fundraising details, fund flows, recipient feedback, etc., can be stored on the blockchain and transparently and publicly disclosed conditionally to facilitate social supervision.

4. Insurance field

In terms of insurance claims, insurance institutions are responsible for fund collection, investment, and claims settlement, and often have high management and operating costs. Through the application of smart contracts, there is no need for the policy holder to apply or the insurance company to approve it. As long as the claim settlement conditions are triggered, the insurance policy can automatically settle claims.

⑺ Are Bitcoin and Blockchain the same?

No, Blockchain is a technology of Bitcoin. Chain is a blockchain company, you can learn more about it!
