1. What is the relationship between Bitcoin and blockchain?
In simple terms:
1. Bitcoin is a digital currency, and blockchain It's a technology.
2. Blockchain is the underlying technology of Bitcoin, and Bitcoin is the first application of blockchain technology; as a state-supported and vigorously developed blockchain technology, it will be widely used in the future All walks of life.
3. Blockchain technology is not a new technology, but a new logic of thinking. It just rearranges and combines many previously unrelated algorithmic technologies.
4. Blockchain is a block connected to a block. Thousands of blocks form a chain. To connect the next block, you need to calculate the algorithm. The answer (mining), and the reward for mining is Bitcoin.

2. What is data blockchain (BlockChain)
What is data blockchain (BlockChain)? 1. Data blockchain is an important concept in the Bitcoin financial system. It records transaction record data on the entire Bitcoin network, and these data are shared by all Bitcoin nodes. Through data blocks, we can Query the history of every Bitcoin transaction.
2. Example:
There are three persons A, B and C. All the funds of A and B are kept by C. And every financial transaction must be recorded by C. Now assume that A and B each have 1 million in custody of C. Then:
A spends 80,000 yuan to B, then C’s record in the account book will subtract 80,000 yuan from A’s name, and add 80,000 yuan to B’s name.
If B transfers 50,000 yuan to A, then C will add 50,000 yuan to A’s name in the account book, and subtract 50,000 yuan to B’s name.
A spends 50,000 yuan to B, then C's account book record will subtract 50,000 yuan from A's name, and add 50,000 yuan to B's name.
3. The role of the data blockchain is similar to that of C’s account record book. It records the user’s ownership of Bitcoin and the records of all users’ Bitcoin transactions. It’s just that this “account record book” is recorded by the mining software of every Bitcoin miner on the Internet. If a Bitcoin transaction is confirmed by the data blockchain, the relevant information will be recorded in the data blockchain. Bitcoin’s “account record book” is called the data blockchain. All data blockchains on the Internet form Bitcoin’s decentralized network database system.
4. The essence of data blockchain technology is a decentralized and distributed structure of data storage, transmission and certification methods. Data blocks replace the current Internet's reliance on central servers, making all Data changes or transaction projects are recorded on a cloud system, which theoretically realizes self-certification of data during data transmission. In a far-reaching sense, this goes beyond the traditional and conventional information verification formalities that require reliance on a center.ization, reducing the cost of establishing global "credit". This point-to-point verification will produce a "basic protocol", which is a new form of decentralized artificial intelligence and will establish a new interface and sharing of human brain intelligence and machine intelligence. interface.
Blockchain is a new application model of computer technologies such as decentralized data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system. Shanghai Heshu Software Co., Ltd. is an innovative technology enterprise focusing on the R&D and application of blockchain technology and a professional blockchain technology service provider. The team has been developing blockchain technology since 2016, and has conducted in-depth research on blockchain technology fields such as blockchain encryption algorithms, consensus mechanism network security, decentralization, and point-to-point.

is a public list of all transactions that have been sent, which ensures that everyone knows the true owner (address) of each Bitcoin. All fully functional nodes on the network will retain a copy of the blockchain.
Block is an independent unit on the blockchain. Each block contains the hash value of the previous block (so it is impossible for someone to remove or modify any block on the blockchain without causing some of the hashes in the blockchain to mismatch), and also There are as many unconfirmed transactions as can be found on the Internet, and a number called a nonce. Someone who is building a block must find a suitable nonce so that the hash value of the block is below a certain threshold (the target value). This can only be done by trying all the nonces one after another. number until one produces the desired hash valueThe random number is found, the lower this target value the harder it is to find a suitable random number. Block creation is intentionally made so difficult to prevent someone from spending Bitcoin and then creating and advancing his own blockchain that does not contain the transaction that shows the Bitcoin has been spent, a wipe The transaction record just now allows him to spend the Bitcoin twice. When a valid block is created, it is distributed throughout the network and the search for the next block begins based on this block.
What is blockchain and what is big data
1. Blockchain: It is a new type of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Application mode. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system.
Blockchain is an important concept of Bitcoin, mentioned in the "2014-2016 Global Bitcoin Development Research Report" released by the Internet Finance Laboratory of Tsinghua University PBC School of Finance and Sina Technology. 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 and is used to verify the validity of the information (anti-counterfeiting) and generate the next block. .
2. Big data: refers to a collection of data that cannot be captured, managed and processed with conventional software tools within a certain time range. It requires new processing models to have stronger decision-making power, insight discovery and process optimization capabilities. massive, high-growth and diversified information assets.
The concept of blockchain is so popular! Will blockchain technology become a new trend?
In recent years, the development ecosystem of blockchain has gradually been improved and enriched. Industry insiders believe that with national policy support, widespread attention and financial support, blockchain technology can achieve gradual and stable progress. Although the upside prospects of blockchain technology are broad, we must remain calm about this.
What is the relationship between blockchain and big data? Will blockchain replace big data? The relationship between blockchain and big data is not very big. Big data is mainly about managing massive amounts of data, and the core of blockchain is to achieve high security and reliability of data without centralized intermediaries. Jinwowo Network Technology
Therefore, blockchain and big data do not conflict with each other, nor will they replace them. They are completely different solutions for data in different scenarios.
3. 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. Later, Bitcoin technology was abstracted and called blockchain technology, or distributedledger 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.
(3) BT technology and blockchain technology extended reading:
Bitcoin currency characteristics:
Decentralization: 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.
Worldwide circulation: Bitcoin can be managed on any computer connected to the Internet. 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.

4. What technology will solve the problem of reliable transmission of trust and value on the Internet in the future labor environment
Blockchain technology will solve the problem of reliable transmission of trust and value on the Internet in the future labor environment.
Internet:
The Internet (English: internet), also known as the Internet or transliterated Internet, Internet, is the connection between networks. A huge network connected in series. These networks are connected by a set of universal protocols to form a logically single huge international network. This method of interconnecting computer networks can be called "network interconnection". On this basis, a global Internet network covering the world has been developed called the "Internet", which is an "interconnected network".
The Internet is not the same as the World Wide Web. The World Wide Web is just a global system based on hypertext links and is one of the services that the Internet can provide. When talking about the Internet alone, it usually refers to the Internet or a network connected to it. Sometimes it is simply called the Internet or the Network (theNet), which can be used for communication, social networking, and online trade.
5. Broad definition of blockchain technologyWhat is the definition of justice and chivalry?
The so-called blockchain technology,
referred to as bt (blockchain
technology), is also called distributed ledger technology and is an Internet database. Technology is characterized by decentralization, openness and transparency, allowing everyone to participate in database records.
Explained in layman’s terms: If we assume that the database is a ledger, reading and writing the database can be regarded as an accounting activity. The principle of blockchain technology is to find the fastest and most efficient accounting method within a period of time. A good person, this person will keep accounts, and then send this page of information in the ledger to everyone else in the entire system. This is equivalent to changing all the records in the database and sending them to every other node in the entire network, so blockchain technology is also called a distributed
ledger.
6. What is blockchain technology? What exactly is blockchain?
1. The so-called blockchain technology, referred to as BT (Blockchain technology), is also known as Distributed ledger technology is an Internet database technology that is characterized by decentralization, openness and transparency, allowing everyone to participate in database records.
Explain in layman’s terms: If we assume that the database is a ledger, reading and writing the database can be regarded as an accounting behavior. The principle of blockchain technology is to find out the accounting information within a period of time. The fastest and best person will keep accounts, and then send this page of information to everyone else in the entire system.
2. Blockchain is a new application model of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies.
Blockchain is an important concept of Bitcoin. It is essentially a decentralized database. As the underlying technology of Bitcoin, it is a series of cryptographic methods. Each data block generated by the association 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.
(6) Extended reading on bt technology and blockchain technology:
The blockchain system consists of data layer, network layer and consensus layer , incentive layer, contract layer and application layer. Among them, the data layer encapsulates the underlying data blocks and related basic data and basic algorithms such as data encryption and timestamps; the network layer includes distributed networking mechanisms, data dissemination mechanisms, and data verification mechanisms; the consensus layer mainly encapsulates network nodes Various consensus algorithms.
The incentive layer integrates economic factors into the blockchain technology system, mainly including the issuance mechanism and distribution mechanism of economic incentives; the contract layer mainly encapsulates various scripts, algorithms and smart contracts, and is the The basis of the chain's programmable features; the application layer encapsulates various application scenarios and cases of the blockchain.
7. Blockchain and Bitcoin haveWhat are the differences and connections?
Blockchain technology is a new technology derived with the development of the Bitcoin economy. Blockchain technology can effectively serve the Bitcoin economy, and they are interrelated. Bitcoin is a virtual currency that only circulates in a specific network economic environment. Blockchain technology can not only be applied to the economy, but can also be used in all walks of life. This is their difference.
Blockchain TechnologyBecause blockchain technology is still an emerging product, it does not yet have an accurate or definite definition and concept. Simply put, blockchain technology is a model for encrypted management of data, which can protect data to a large extent. Blockchain technology has the distinctive characteristics of decentralization, openness, independence, security and anonymity. Its characteristics are well adapted to today's requirements for information protection and information disclosure in all walks of life. On the one hand, it ensures data security and prevents data processing from being interfered by factors such as human subjective emotions and system failures. On the other hand, it is up to the individual data to decide whether to hide their details from the group to the greatest extent possible to achieve the purpose of protecting privacy.
At the same time, there is no doubt that blockchain technology is still in a preliminary state of development. Society's understanding of it is not deep enough, and scholars are still in the stage of continuous exploration. Through correct application, blockchain technology will bring many positive impacts to society.
