Blockchain, what is a block

Comprehensive interpretation of blockchain

When talking about blockchain, people always compare it with Bitcoin. On October 31, 2008, a person named "Satoshi Nakamoto" sent an email to a cryptography email group, claiming, "I have been working on a new electronic cash system, which is completely peer-to-peer and does not require Any trusted third party.” He launched a new system using Bitcoin as the transaction currency.

What is blockchain technology? What is blockchain?

Blockchain is a distributed shared accounting technology. What it wants to do is to allow all parties involved to establish a trust relationship at the technical level.

Blockchain can be roughly divided into two levels. One is the underlying technology of the blockchain; the other is the upper-layer application of the blockchain, that is, transformation based on the blockchain, Optimize or innovate applications.

What is the core meaning of blockchain? Our understanding is that the core meaning of blockchain is to establish data credit among participants, and to create a single transaction under clear regulations through unilateral confrontation. The ecology of all aspects jointly guarantees complete opportunities. This is a system. This establishment can end the problems before the blockchain. Before the blockchain, it was impossible to achieve new sharing when data was shared, even if it was targeted. It just gives you an interface. After the blockchain is established, the participants can realize the sharing of credit.

What are the underlying platforms of blockchain?

Answer: There are mainly the following categories:

1. Bitcoin. The earliest blockchain development was based on the Bitcoin blockchain network. Since Bitcoin is the most widely used and truly decentralized in the world, in terms of blockchain applications, Bitcoin is the most widely used blockchain in the world. A strong anchor with the greatest authority.

2. EtherSquare. It can be said that apart from Bitcoin, Ethereum is currently the most eye-catching blockchain platform. Ethereum is a Turing-complete blockchain one-stop development platform that uses multiple programming languages ​​to implement protocols. It uses a client written in Go language as the default client (i.e., the method of interacting with the Ethereum network, and supports many other language client).

3. IBM HyperLedger. Also called fabric, its goal is to build a super ledger that is jointly maintained by the whole society. Fabric originated from IBM. Its original intention was to serve industrial production. IBM open sourced 44,000 lines of code, which is a great contribution and allows us to have The opportunity is so close to explore the principles of blockchain that are different from Bitcoin.

4. LISK. It is a new generation of blockchain platform that allows the development of JavaScript (Javascript technology again, engineers, take note) and distribution-based decentralized applications using an easy-to-use, full-featured ecological blockchain system.

5. Online recording blockchain platform. It is the research and development result of the underlying technology of the Wanglu blockchain and a basic platform capable of commercial delivery. In addition to serving the Wanglu public chain, the Wanglu blockchain platform is also the basic platform for Wanglu to create private chains and alliance chains for customers.

What is blockchain? What is blockchain for digital currencies?

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 non-forgeable. 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, uses cryptography to ensure the security of data transmission and access, and uses automated scripts to A new distributed infrastructure and computing paradigm that uses smart contracts composed of code to program and manipulate data.
Nowadays, mainstream digital currencies are basically developed based on blockchain technology. Blockchain is the underlying technology of digital currency. The domestic tea-based digital currency Puyin was developed based on blockchain technology.

What is blockchain

The essence of blockchain is a decentralized accounting system, and Bitcoin is the currency that "exists in digital form" carried on this system. Blockchain is a system behind Bitcoin that consists of credit records and the settlement of credit records.

Blockchain is a new application model of computer technologies 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].
Blockchain is an important concept of Bitcoin. Huobi.com cooperates with Tsinghua University PBC School of Finance Internet Finance Laboratory and Sina TechnologyThe "2014-2016 Global Bitcoin Development Research Report" released mentioned that blockchain is the underlying technology and infrastructure of Bitcoin [2]. It is essentially a decentralized database and serves as the underlying technology of Bitcoin. Blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a Bitcoin network transaction, which is used to verify the validity of its information (anti-counterfeiting) and generate the next block< br /> The evolution of blockchain is:
▪ Blockchain 1.0 - digital currency
▪ Blockchain 2.0 - digital assets and smart contracts
▪ Blockchain 3.0— —IFMChain, blockchain officially links mobile terminals

❸ Advantages of blockchain technology Classification of blockchain technology

The development of blockchain technology continues to expand with the expansion of applications It is becoming more and more prosperous. This powerful development force coming from the needs of various industries has caused rapid changes in blockchain technology, making the results achieved by various industries more and more attractive, from professional technology to resources. The focus on this industry has brought the development of blockchain technology to a new stage, and the impact of this development of blockchain technology has also attracted much attention.

When talking about blockchain technology, Bitcoin has to be mentioned. Many people know that the electronic currency Bitcoin does not rely on the issuance of a specific monetary institution, but is generated through a large number of calculations by a specific algorithm. In fact, the core that truly supports Bitcoin is blockchain technology.

How does the invisible and intangible Bitcoin operate through blockchain technology? The interpretation circulated in the industry is that blockchain can be regarded as a technical solution for collectively maintaining reliable databases through "decentralization" and "trustlessness". In layman’s terms, this technology can be understood as a technology in which everyone participates in accounting. In the past, people used centralized servers to keep accounts, but in the blockchain technology system, everyone can participate in accounting and jointly identify Authenticity of records.

“Through this technology, even if there is no neutral third-party organization, two parties that do not trust each other can achieve cooperation. In short, the blockchain is like a ‘machine that creates trust’. "Bubi Company is a leading blockchain service provider in China. It has made many breakthroughs in the blockchain technology platform, can meet scenarios with tens of millions of users, and has the ability to quickly build upper-layer application businesses.

The blockchain technology used by all parties involved in recording and storing information adopts a decentralized distributed structure, which saves a lot of intermediary costs and can better ensure data security; at the same time, it cannot be tampered with Timestamps can effectively solve problems such as data tracking and information anti-counterfeiting.

Will it become the next trend of Internet finance?

Although blockchain emerged with Bitcoin, the derived value of this technology hasBeyond digital currency. Bubi Blockchain focuses on the innovation of blockchain technology and products. It already possesses a number of core technologies and has developed its own blockchain service platform. With decentralized trust as the core, we are committed to building an open value circulation network to allow digital assets to flow freely. What Bubi wants to do is to create a new technology and product - to realize real value circulation and bring the Internet to a new level. With the application of this technology, there will be no central organization when transferring assets, and direct transfer of assets between us can be achieved.

In the current international financial market, the U.S. Central Bank, Swiss Bank, and some insurance and futures companies are all competing to develop blockchain technology. Fang Liang introduced that in the Internet financial industry, blockchain technology will first affect financial infrastructure such as payment systems, securities settlement systems, and transaction databases; later, the technology will also expand to general financial services, such as credit systems and "anti-money laundering" "wait.

“The payment and clearing system in the financial field will evolve towards decentralization. The electronic ledger supported by blockchain technology is a reliable system that is error-free and cannot be tampered with. Quan and others have a profound impact." Li Yan said.

Therefore, industry insiders believe that blockchain technology may be the next trend in the Internet financial industry. As the interconnection of all things deepens, Yang Tao, assistant director of the Institute of Finance, Chinese Academy of Social Sciences, also said that blockchain will make it possible for all individuals to become important nodes in the allocation of financial resources, and will also promote the improvement of existing financial system rules. Build a shared and win-win financial development ecosystem.

Blockchain technology will affect many industries

“Blockchain technology has been widely used in the era of big data.” Li Yan said frankly that in addition to the Internet financial field, Blockchain technology has been applied in many fields and has shown great prospects.

For example, the healthcare industry has benefited greatly from blockchain technology. In reality, patient private information leaks often occur, and centralized database or file cabinet management in medical departments is no longer the optimal choice. Medical institutions are using blockchain technology to keep patients' private information confidential.

In addition, blockchain technology also has important legal implications. In some civil fields, it is often necessary to provide evidence to determine blame, and blockchain technology can record every step and help judicial authorities identify the specific responsible person.

“Especially in the field of assets, whether it is physical assets such as real estate and cars, or intangible assets such as health and reputation, this technology can be used to complete registration, transactions, and tracking. It can be said that any lack of Blockchain technology will be useful in all areas of trustful production and life."

The development of blockchain technology has also brought about changes in the operational concepts of various industries. New technologies and new concepts have promoted New developments in various industries, this driving force hasThe impact on society and the promotion of economic activities are also huge. Many new industry phenomena will occur one after another, and the public is also waiting and watching, expecting this brand-new technology to be used by various industries and better benefit all industries.
