比特币使用的区块链属于什么链?,比特币使用的区块链属于什么链接

区块链是近年来最受关注的技术之一，其实就是一种使用记录技术来维护不可变的数据库。比特币是一种使用区块链技术的加密货币，它利用区块链的分布式账本技术，可以实现货币的安全交易。那么，比特币使用的区块链属于什么链呢？今天，我们就来聊聊比特币使用的区块链属于什么链？

首先，比特币使用的区块链属于公有链。公有链是公开可见的区块链，任何人都可以参与，共同维护网络，也可以自由地在其中参与货币交易。比特币是一种去中心化的数字货币，其中所有的交易都是完全开放的，每一笔交易都将被记录在区块链上。比特币的发行和管理都是完全交给社区来实施，这也是公有链的一大特点。

其次，比特币使用的区块链属于去中心化链。去中心化链是指没有中心化管理机构的区块链，它是一种完全去中心化的分布式账本技术，它不需要任何中央机构来管理，只需要社区中的矿工来维护区块链的安全性，确保每一笔交易都是可信的。比特币的发行和管理都是完全交给社区来实施，这也是去中心化链的一大特点。

最后，比特币使用的区块链属于加密货币链。加密货币链是一种使用加密技术的区块链，它利用加密技术来保护比特币的安全性，以及保护比特币交易的安全性。比特币是一种加密货币，它使用区块链技术来实现安全的货币交易，而这种交易是完全不可逆的。比特币使用的区块链就属于加密货币链，它可以保证比特币的安全性，以及比特币交易的安全性。

总结一下，比特币使用的区块链属于公有链、去中心化链和加密货币链。公有链是一种公开可见的区块链，去中心化链是指没有中心化管理机构的区块链，而加密货币链是一种使用加密技术的区块链。比特币的发行和管理都是完全交给社区来实施，它利用区块链的分布式账本技术，可以实现货币的安全交易。

A. Comprehensive interpretation of blockchain and Bitcoin, teach you to understand the relationship between the two

01 Blockchain is the underlying technology of Bitcoin
< br />Blockchain is a distributed account, in short, a decentralized ledger that can be viewed and joined by many people. For example, each block is equivalent to each knot on the rope. When each new transaction enters the blockchain, it is equivalent to an event. To mark the occurrence of an event, a symbolic knot is made and the details are recorded on the specific knot

Bitcoin uses blockchain for value storage and transactions. In addition, the technical difficulty of the blockchain itself is not the greatest, but its application scenarios and regulatory issues include three types of blockchain: public blockchain, private blockchain and joint blockchain; the other classification is permissionless and permissions

Therefore, cryptocurrency uses blockchain technology, but blockchain technology does not entirely belong to cryptocurrency

02 When the financial crisis comes, blockchain technology It can prevent counterfeiting, trace the source, and simplify transactions in the financial industry. Some investors choose to invest in cryptocurrency to avoid corresponding asset risks and benefit from the mechanism of blockchain to solve trust problems. This technology has been applied to financial management and transactions. The main performance is that blockchain can track various types of transactions and can also play an anti-counterfeiting and traceability role in various scenarios. Copyright, trademark, academic fraud and other issues have been exposed one after another

In addition, blockchain technology can also simplify transactions, make the entire transaction process open and transparent, track the links of each transaction event, and ensure that both parties have certain rights. Degree of trust

03 The concept of Bitcoin is different from that of blockchain

During the "mining" process, the open source blockchain network can ensure trust and cannot be tampered with. When networked computers run through a precise algorithm and give the correct answer, the "absentees" will be rewarded for mining and have access to servers around the world, but the whole process is still very energy-consuming

Currency Chart B Coin: A comprehensive explanation of blockchain and Bitcoin will teach you to understand the relationship between them. Bitcoin is an open source version of blockchain technology, that is, a network developed for everyone, and it is popular for its decentralized advantages. However, as a public blockchain, Bitcoin consumes a lot of computing power due to mining, which leads to severe power consumption in many countries

Therefore, for an emerging technology, it is best not to be blind Trust or invest and recognize its true purpose in order to see everything objectively and be prepared.

B. What is the blockchain?

What is the blockchain? New applications of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, and encryption algorithmsmodel. Simply put, blockchain is a decentralized distributed ledger database.

The meaning of data storage:

Data storage is a temporary file generated during the processing of data flow Or the information you need to find during processing. Commonly used storage media are disks and tapes. How storage is organized varies depending on the storage medium. Data on the tape is only accessed in sequential file mode; on the disk, it can be accessed sequentially or directly according to the usage requirements.

The data storage method is closely related to the organization of data files. The key is to establish the correspondence between the logical and physical order of records and determine the storage address to improve the data access speed. Among the various connection methods between servers and storage, DAS was once considered an inefficient structure and inconvenient for data protection.

Direct-attached storage cannot be shared, so it often happens that a certain server has insufficient storage space, while other servers have a large amount of idle storage space that cannot be used.

C. Classification of blockchains

Currently blockchains are divided into three categories, among which hybrid blockchains and private blockchains can be regarded as: generalized private chain, public area Blockchain public blockchain. This means that any individual or group in the world can send transactions, the transactions can be effectively confirmed by the blockchain, and anyone can participate in its consensus process. Public blockchain is currently the earliest blockchain and the most widely used blockchain. Each virtual digital currency of the Bitcoin series is based on a public blockchain, and there is only one blockchain in the world corresponding to this currency.
Extended information
1. Industrial blockchain industry blockchains: multiple pre-selected nodes in the group are designated as bookkeepers, and the generation of each block is jointly decided by all pre-selected nodes (pre-selected nodes participate in the consensus process), others Access nodes can participate in transactions but do not interfere with the accounting process (essentially, it is managed bookkeeping, but it becomes distributed bookkeeping). How many pre-selected nodes and how to determine the bookkeeper for each block become the main risk points of the blockchain ), anyone else can make limited queries through the blockchain’s open API. Private Blockchain Private Blockchain ((privateblockchains)): Only the general ledger technology of the blockchain is used for accounting. It can be a blockchain with exclusive written permission from a company or individual. This chain is not much different from other distributed storage solutions. At present (December 2015), conservative giants (traditional finance) want to try private blockchains, while the applications of public chains, such as Bitcoin, have been industrialized, and the application products of private chains are still being explored. Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. Blockchain is an important concept of Bitcoin. Essentially, it is a decentralized database.
2. At the same time, as the underlying technology of Bitcoin, it is a series of encryption methods related tolinked data blocks. Each data block contains a batch of Bitcoin network transaction information, verify the validity of its information (anti-counterfeiting) and generate the next block. In fact, the word blockchain does not appear in the original English Bitcoin white paper, but appears in blockchain. In the earliest Bitcoin white paper, blockchain was translated as blockchain. This is the time when the Chinese word "blockchain" first appeared. The Cyberspace Administration of China issued the "Blockchain Information Service Management Regulations" on January 10, 2019, which came into effect on February 15, 2019. In a narrow sense, a blockchain is a chained data structure that combines data blocks in chronological order, and a tamper-proof and forgery-proof distributed ledger guaranteed by cryptography. Broadly speaking, blockchain technology is a new distributed infrastructure and computing method that uses blockchain data structures to verify and store data, distributed node consensus algorithms to generate and update data, and cryptography to Ensure the security of data transmission and access, using smart contracts composed of automated script code to program and operate data.

D. What is the relationship between blockchain and Bitcoin

Blockchain technology is the basic technology of Bitcoin and is also the core and infrastructure of Bitcoin. Bitcoin has always been operated and managed without any centralized organization. Later, Bitcoin technology was abstracted and called blockchain technology, or distributed ledger technology.

(1) Blockchain is the core and infrastructure of Bitcoin:

1. In the Bitcoin system , "currency" is simply the unit of account used in that ledger. The most important thing is not the concept of "currency", but the concept of "ledger" without a central storage organization. For example: I lend 50 yuan to someone else. At this time, I asked the financial staff to help me keep accounts.

2. Blockchain technology is the basic technology of Bitcoin and the core and infrastructure of Bitcoin. Bitcoin has always been operated and managed without any centralized organization. Later, Bitcoin technology was abstracted and called blockchain technology, or distributed ledger technology.

(2) Blockchain is the core and infrastructure of Bitcoin:

1. In the Bitcoin system, “currency” is just the accounting used in the ledger. unit. The most important thing is not the concept of "currency", but the concept of "ledger" without a central storage organization. For example: I lend 50 yuan to someone else. At this time, I asked the financial staff to help me keep accounts. Bookkeeping must be paid, so I need to pay the financial staff.

Because an incentive mechanism has also been invented in the Bitcoin system technology, which is equivalent to what I just said, you can help me keep accounts and I will pay you, but not everyone can keep accounts. rewards. Therefore, the blockchain has designed a corresponding mechanism competition mechanism.

2. The competition mechanism uses a hash algorithm to determine the ownership of rewards. Generally speaking, everyone is given a math problem. The reward is for whoever calculates the result first. The calculation process of the hash algorithm uses a professional computer (we call itminer) The process of calculating results using a hash algorithm is called mining.

For the fastest and best bookkeepers, the system writes the recorded contents into the account books and sends the account book contents to everyone in the system for backup. This way, everyone in the system has a complete ledger called blockchain technology.

(3) The origin of blockchain:

1. The origin of the word "blockchain" is from the original English version of the Bitcoin white paper "Blockchain". When translating this sentence, the Chinese market directly used the word "blockchain" and then directly wrote it as "blockchain", which became a proper noun at the global blockchain technology level.

So, no matter who explains the blockchain, Bitcoin cannot be bypassed. If you want to introduce the history of cars, just like you can't avoid Carl Benz; if you want to introduce the history of airplanes, just like the Wright brothers.

2. Bitcoin "invented" and proved the feasibility of blockchain technology. Bitcoin is not the entire blockchain technology, just one of its applications. But without Bitcoin, or if Bitcoin's applications were not successful, blockchain might not have emerged, or at least not for many years. Therefore, it is difficult for the blockchain to be "isolated" from Bitcoin for a long time.

(4) What chain does the blockchain used by Bitcoin belong to? Extended reading:

Districts applied to digital currency Disadvantages of blockchain technology:

First, "delegation" does not have a circulation management agency. In essence, blockchain technology is a distributed database system, its logical structure is a one-way linked list, and its design model is based on P2P network, which determines that there is currently no unified virtual currency central control system based on blockchain technology. .

Second, quantity supply is difficult to effectively control. Based on blockchain technology, the issuance amount of virtual currency is fixed. According to the Fisher equation, at a certain price level, the total transaction volume of the whole society in a certain period has a certain ratio to the required nominal amount of money, and a fixed amount of money obviously cannot meet the requirements of the ever-increasing total price of social commodities.

Third, it is difficult for the “mining mechanism” to create recognized value. Bitcoin itself has no value and is not backed by national credit. Some people think that "value is injected into virtual currency by continuously consuming computing power and energy", but in order to find a hash value that meets the requirements, spending millions of calculations is obviously not the most efficient option.

Fourth, producers and early holders can easily obtain high seigniorage taxes. Any virtual currency based on blockchain technology will be held by a small number of people in the early stages of development. Take Bitcoin for example. At first, Bitcoin was just a product of a few people's game. In May 2010, the first transaction to buy Bitcoin was a $25 pizza purchased for 10,000 Bitcoins, and the first transaction completed in July of the same year was $0.04/Bitcoin.

E. What is blockchain technology? What exactly is blockchain?

Blockchain technology is one of the top ten typical judicial technology applications on the Internet.Use one. Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms.

Blockchain is an important concept of Bitcoin. In fact, it is a decentralized database. Blockchain, as the underlying technology of Bitcoin, is a series of data blocks generated using cryptographic methods. Each data block contains a batch of Bitcoin network transaction information, which is used to verify the validity of its information (anti-counterfeiting) and generate the next data block.

Blockchain originated from Bitcoin. On November 1, 2008, a person who called himself Satoshi Nakamoto published the article "Bitcoin: A Peer-to-Peer Electronic Cash System", which elaborated on P2P network technology, encryption technology, timestamp technology, and block technology. The concept of electronic cash system framework such as chain technology marks the birth of Bitcoin.

(5) What kind of chain does the blockchain used by Bitcoin belong to? Extended reading:

The birth of the blockchain:

The concept of blockchain was first proposed by Satoshi Nakamoto in 2008. In the following years, blockchain became the core component of the electronic currency Bitcoin: a public account for all transactions. By using peer-to-peer networks and distributed timestamp servers, blockchain databases can be autonomously managed.

The blockchain invented for Bitcoin made it the first digital currency to solve the problem of repeated consumption. Bitcoin design has become a source of inspiration for other applications. On December 20, 2016, the Digital Currency Alliance-China FinTech Digital Currency Alliance and FinTech Research Institute were officially established.

F. What is the relationship between blockchain technology and Bitcoin?

Blockchain technology is the underlying technology of Bitcoin. Bitcoin has always been operated and managed without any centralized organization. Running under the circumstances, Bitcoin technology was later abstracted and called blockchain technology, or distributed ledger technology.

Bitcoin is the first application of blockchain and will be expanded to more and more industries in the future.

Blockchain technology is called distributed ledger technology. It is an Internet database technology that is characterized by decentralization, openness and transparency, allowing everyone to participate in database records.

While Bitcoin is not issued by a specific monetary institution, the Bitcoin economy uses a distributed database composed of many nodes in the entire P2P network to confirm and record all transaction behaviors, and uses cryptographic design to ensure A currency that provides security in all aspects of currency circulation.

(6) What chain does the blockchain used by Bitcoin belong to? Extended reading:

Bitcoin currency characteristics:

Go Centralization: Bitcoin is the first distributed virtual currency. The entire network is composed of users and there is no central bank. Decentralization is the guarantee of Bitcoin’s security and freedom.

Circulation around the world: Bitcoin can be managed on any computer connected to the Internetreason. Anyone can mine, buy, sell or receive Bitcoin regardless of location.

Exclusive ownership: Manipulating Bitcoin requires a private key, which can be isolated and stored on any storage medium. No one can obtain it except the user himself.

Low transaction fees: It is free to remit Bitcoin, but there will ultimately be a transaction fee of approximately 1 bit cent per transaction to ensure faster transaction execution.

No hidden costs: As a means of payment from A to B, Bitcoin has no cumbersome limits and procedures. You can make the payment by knowing the other party's Bitcoin address.

Cross-platform mining: Users can explore the computing capabilities of different hardware on many platforms.

G. What kind of blockchain does Bitcoin belong to?

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", created a reliable "cooperation" mechanism, and has broad application prospects. Bitcoin is a form of expression of blockchain. .

(7) What chain does the blockchain used by Bitcoin belong to? Extended reading

To mine Bitcoin, you can download a dedicated Bitcoin computing tool, and then Register for various cooperative websites, fill in the registered username and password into the calculation program, and then click the calculation to officially start. After completing the Bitcoin client installation, you can directly obtain a Bitcoin address. When others pay, you only need to post the address to others, and you can pay through the same client.

After installing the Bitcoin client, it will be assigned a private key and a public key. You need to back up your wallet data containing your private key to ensure that your property is not lost. If unfortunately the hard drive is completely formatted, one's Bitcoins will be completely lost.

H. What are the three major public chains of blockchain

Public chain, public chain The abbreviation refers to a blockchain that can be read by anyone in the world, anyone can send transactions, and transactions can be effectively confirmed and 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 release 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 the consideration of injecting the long-term value of HT into a unified value carrier, 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.

I. What is digital currency blockchain

1. Blockchain is a ledger that records digital currency transactions
Take Bitcoin as an example, it does not Entity form, but exists in a dedicated ledger. All Bitcoin transactions are recorded in the ledger. Through the transaction records, we can calculate the number of Bitcoins owned by each user. If a person owns Bitcoin, it means that transaction records related to him can be found in the ledger.
The ledger mentioned here is a piece of software, which we can download from the official Bitcoin website, and the underlying technology used in this software is the blockchain. To facilitate understanding, we usually say that the blockchain is the ledger.
The reason why blockchain is used as the underlying technology of the ledger is to achieve the decentralization of digital currency. It can be said that the starting point for a series of problems encountered by digital currencies and the solutions provided comes from decentralization.
2. Blockchain is a technology that ensures the safe use of digital currencies. Everyone knows that blockchain technology has two major characteristics: encryption and non-tamperability. It canThe probability of errors during the use of digital currency is reduced to 0. Since digital currencies have higher requirements for encryption, blockchain technology must be used to support them. Currently, not only many industries in our country are using blockchain technology, but many foreign countries are also actively using blockchain technology. Blockchain technology.
[Extended information]
Blockchain is the underlying technology of digital currency, and Bitcoin is the first successful application of blockchain.. To understand this problem, we must first recognize the facts: not all blockchains require Issuing digital currency, currently our country strongly supports "coinless blockchain". Generally speaking, public blockchain, that is, public chain, needs to issue tokens as "rewards" to motivate users and maintain system operation, while ordinary blockchain , often called a consortium chain, can or cannot be issued. Private blockchains are mostly used for company internal audits and generally do not need to issue coins. The following is a detailed explanation of the differences between the three blockchains:
1. Public block Chain: A blockchain in which anyone in the world can read and send transactions for validity confirmation, and anyone can participate in its consensus process. Bitcoin and Ethereum are typical applications of public blockchains. Public blockchains are a global Distributed blockchain, blockchain data is open, user participation is high, and it is easy to produce network effects, easy to apply and promote. Therefore, this kind of blockchain operation relies heavily on the incentive mechanism, Bitcoin Tokens such as Ethereum and Ethereum are used as "rewards" for incentives, so public chains need to issue tokens to maintain their own development and ecology.
2. Community Blockchain (Alliance Chain): It means that the participation of nodes in the blockchain is selected in advance. There are usually good network connections and other cooperative relationships between nodes. The data on the blockchain can be open It can also be internal. For partial distribution, we can regard it as "partial decentralization". Each alliance in the chain has its own centralized management. For example, R3CEV of more than 40 banks is a typical alliance chain. Chains usually don’t require a lot of money, but there are also individual alliance chains that choose to send money to motivate members within the alliance to contribute, so there are no restrictions on the chain.
3. Private blockchain: refers to a node with a limited scope of participation, such as a specific organization’s own users, strict permission management for data access and use.. Write permissions in a completely private blockchain It is only in the hands of the participants, and the read permission can be opened to the outside world or restricted to any extent. It is currently mainly used for internal audit work of the company. Therefore, the private chain does not need to issue currency, and it does not have the characteristics of decentralization. It is a kind of centralization management mechanism.
