What is the technical protocol at the bottom of the blockchain?

　　Jinwowo Network Technology analyzes the following points:

　　1-Consensus mechanism;

　　2-Distributed data;

　　3-Cryptographic technology;

　　4-Smart contracts;

　　5-Authentication access;

　　6-Node management. What is blockchain?

　　Blockchain (Blockchain) is the underlying technology of Bitcoin, like a database ledger, recording all transaction records. This technology has also gradually received attention from the banking and financial industries due to its security and convenience.

　　Blockchain (Blockchain) is an important concept of Bitcoin, which is essentially a decentralized database and also serves as the underlying technology of Bitcoin. Blockchain is a series of data blocks generated by cryptographic methods, each containing information about a Bitcoin network transaction, used to verify the validity (anti-counterfeiting) of the information and generate the next block.

　　The blockchain is public on the network and can be queried in each offline Bitcoin wallet data. The function of the Bitcoin wallet depends on the confirmation with the blockchain, and one valid check is called one confirmation. It usually takes several confirmations for a transaction to proceed. Lightweight Bitcoin wallets use online confirmation, which means that they will not download blockchain data to the device storage.

　　Many competing coins of Bitcoin also use the same design, but there are slight differences in the proof of work and algorithms. For example, using Proof of Stake and SCrypt, etc.

　　Blockchain is the underlying protocol and basic technology of digital encrypted currencies such as Bitcoin, Raitai Coin, Weimob Coin, Litecoin, and Ethereum.

　　What does blockchain technology mean?

　　Blockchain has two meanings:

　　1. Blockchain (Blockchain) is a new application mode of computer technology, including distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. The so-called consensus mechanism is a mathematical algorithm that enables different nodes in the blockchain system to establish trust and obtain rights and interests.

　　2. Blockchain is the underlying technology of Bitcoin, like a database ledger, recording all transaction records. This technology has also gradually received attention from the banking and financial industries due to its security and convenience.

　　Narrowly speaking, blockchain is a chain-like data structure that combines data blocks in chronological order and ensures the non-tamperable and non-forged distributed ledger in a cryptographic manner.

　　In a broad sense, blockchain technology is a new distributed infrastructure and computing method that uses block chain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses smart contracts composed of automated script code to program and operate data.

　　The English name for blockchain is Blockchain, which is translated into Chinese as a direct translation, just like the Internet. In fact, blockchain is a kind of underlying protocol, roughly speaking, it has several parts:

　　The first is the distributed ledger; the second is decentralized trust; the third is asymmetric encryption; the fourth is timestamp; the fifth is smart contract. These five underlying technologies sound a bit mystical and everyone sounds like they understand a little.

　　Why does the distributed ledger appear?

　　This involves the second issue, that in the Internet age, although the Internet has penetrated into every aspect of our lives, especially intelligent Internet and mobile Internet, it has completely changed our lives.

　　But the Internet has a very big bug, that is, the biggest problem to be solved at the beginning of its invention was the transmission of information.

　　We know that the transmission of human information has gone through a long era, from the earliest signal fire, without telegraph and telephone, China’s ancient imagination of the千里眼 (a mythical being with superhuman vision) and顺风耳 (a mythical being with superhuman hearing), to the later wired telephone, to the wireless telephone, and then to the network that connects the whole world into one family.

　　But what does the Internet actually transmit? It is information.

　　The earliest internet transmission only transmitted a few English letters, called ‘Login’, which is a word in English, meaning login—the letters ‘Login’ are login.

　　In order to test the transmission function of the internet, we need to verify and not transmit wrong information.

　　So on one hand, we use online transmission, and on the other hand, we also use phone lines to say that I want to send something to you, I sent an ‘L’, did you receive it? Everyone cheered, and it was received on the other side.

　　Then a ‘O’ was transmitted, did you receive it? Yes, I received it. But when it came to transmitting the third letter ‘G’, the system crashed and it didn’t send it.

　　So this is the first time in human history that the internet has transmitted, and it only transmitted two letters, ‘LO’.

　　Think about it, it’s quite tragic. If you want to send a text message to your girlfriend, saying ‘ILOVEYOU’, but the last two letters didn’t send, and it became ‘LO’, making your girlfriend think you are calling her a LOW person. A beautiful marriage may end up in vain.

　　People’s requirements for information are getting higher and higher. In the past, there was no mobile phone signal in many places, including basements.

　　The mobile phone signal equipment in many developed countries does not have such a high coverage as China’s mobile phone signal coverage.

　　In many places, there is no signal, and foreigners are also accustomed to this kind of life, without signal is fine.

　　But for Chinese people, the symbol of a region’s economic development is to see the extent of mobile phone signal coverage.

　　When encountering large-scale gatherings, both China Mobile and China Telecom need to dispatch emergency equipment because thousands of people will gather in an auditorium at once, and the signal of the phone is lost, so what should we do? We need to add emergency vehicles.

　　This time I went to the wine party and saw that the surrounding area was full of China Mobile’s emergency vehicles.

　　It was thought that there was an emergency event, but it was just to ensure that everyone receives the signal of the phone, contacts in time, and刷微信in time, Chinese people have a kind of information anxiety.

　　But the internet has only been able to solve the transmission of information so far, from the earliest transmission of a Login to slowly transmitting audio, video, and other things.

　　In the future 5G era, including Elon Musk’s Sky Internet, which is said to cover the entire Earth with satellites after that, the transmission speed will be 180 times faster than now. That is, if there is a movie, it can be transmitted to you at once.

　　However, the internet cannot solve the transmission of value.

　　What is the transmission of value?

　　For example, if I want to send you one yuan, then this requires a process called accounting.

　　I cannot say that I have given you one yuan and I still have one yuan in my account. This information is like this, I save an information here, I send it to ten people, but this information still exists.

　　It is said that information does not increase or decrease because of the number of times it is transmitted, but money is different.

　　If value is transmitted through the internet, some people will, like playing Mahjong, get confused.
betting online website lottery online and The latest method
　　Because when playing Mahjong, we all know that the money lost and won never match up.

　　At this time, for example, if you give someone one yuan, your account needs to be deducted one yuan, and the other person needs to be added one yuan.

　　If you give ten people ten yuan, then your account needs to be reduced by ten, and each of the ten people needs to be increased by one yuan.

　　So how is it solved at this time? In fact, now it is all using what is called centralized trust.

　　For example, why is Alipay so powerful? Because it solves the trust problem in online shopping.

　　The money is not given to the seller by the buyer first, but to Alipay first. After you receive the goods and verify that they are correct, the money is OK and then transferred to the seller’s account. Alipay plays the role of an intermediary.

　　Of course, Alipay was not invented by Jack Ma. The founder of PayPal, one of the earliest, was Elon Musk, who made his first fortune with the internet to solve centralized trust issues.

　　A通俗 explanation of blockchain

　　1. From an academic perspective, blockchain is a new application model of computer technology such as distributed data storage, peer-to-peer transmission, consensus mechanism, and encryption algorithm. Essentially, blockchain is a decentralized database.

　　2. Blockchain is a term in the field of information technology. Essentially, it is a shared database. The data or information stored in it has characteristics such as ‘unforgeability’, ‘全过程 traceability’, ‘traceability’, ‘openness and transparency’, and ‘collective maintenance’.

　　3. A通俗 explanation of blockchain: Simply put, blockchain is a decentralized distributed ledger database. The advantage of this distributed ledger is that buyers and sellers can directly trade without the need for any intermediaries, and everyone has a backup, so even if your copy is lost, it will not be affected.

　　4. Blockchain is a decentralized distributed ledger database. The advantage of this distributed ledger is that buyers and sellers can directly trade without the need for any intermediaries. Everyone has a backup, so even if your copy is lost, it will not be affected. Suppose you have an account book at home and you are responsible for keeping the accounts.

　　5. Blockchain is a term in the field of information technology. Essentially, it is a shared database, and the data or information stored in it has characteristics such as ‘unforgeable’, ‘全程留痕’, ‘traceable’, ‘open and transparent’, and ‘collectively maintained’.

　　How to correctly understand the protocol layer in blockchain technology?

　　1. For example: you borrowed 100 yuan from me. Everyone in the world knows about it and records it in their respective account books.

　　2. The protocol layer of the blockchain in Chongqing Jinwower analysis includes the following contents: in terms of technology used, the protocol layer mainly includes four aspects: network programming, distributed algorithms, encryption signatures, and data storage technology.

　　3. Blockchain is a type of data structure formed by linking blocks in an orderly manner. A block refers to a collection of data, including relevant information and records, which is the basic unit forming the blockchain. Why choose the Huanhuobao supply chain management system?

　　1. Save transaction costs. Driven by common interests, enterprises coordinate the relationships between trading partners through long-term agreements, which greatly saves the high costs of frequent negotiations, signing contracts, and high fees due to mutual distrust leading to the execution of contracts.

　　2. The supply chain management system helps corporate leaders make more scientific decision-making analyses.

　　3. Improve the supply transparency of enterprises when you have a suitable supplier management system, you can simplify the valuable information and data related to the supplier lifecycle.

　　4. Supply chain management is to coordinate the internal and external resources of enterprises to meet the needs of consumers. When we look at all the enterprises in the supply chain as a virtual enterprise alliance, and treat any enterprise in this virtual enterprise alliance as a department, then the internal management of the alliance is supply chain management.

　　5. (II) Information management. Information and the quality and speed of information processing are the key to whether a company can benefit from the supply chain, and also the key to realizing the overall benefits of the supply chain. Therefore, information management is one of the important aspects of supply chain management.
