Hello everyone, I am Qianxun. A star friend asked before: "How should I choose a job in the development direction of blockchain and big data?" I answered and gave what I thought was a more appropriate suggestion. Fortunately, I Today, let’s talk directly to you about what blockchain is, the relationship between blockchain and Bitcoin, and the working principle of mining. Let’s discuss the principle, value and positive impact of this technology on future society. However, this article requires focused study. Bitcoin is a relatively sensitive word with boundaries. We focus on learning the technical principles of blockchain and the workflow of mining. Don’t do things you shouldn’t do. Ha, hhh.
1. The relationship between mining and blockchain
We have generally heard before that some people are using servers to mine. In fact, the so-called mining, as the name suggests, refers to the process of using computer hardware to perform complex mathematical operations. The principle of making money by mining is that you can get Bitcoin rewards. Bitcoin is a virtual currency and has a certain value relatively speaking. But don’t worry, let’s introduce Bitcoin specifically below. Mining In blockchain technology, mining is an important means of network maintenance and security. The mining process is actually a competition between nodes in the blockchain network to solve a complex mathematical problem. The node that solves the problem will have the right to package a series of transactions to be confirmed into a new block and add it to the block. on the chain.
During this mining process, nodes that solve mathematical problems will receive a certain amount of digital currency as a reward. These rewards not only motivate nodes to participate in maintaining the blockchain network, but also ensure the decentralized nature of the entire network. The figure below is the schematic diagram of the decentralized structure.
2. The relationship between mining and Bitcoin
As the first application of blockchain technology, Bitcoin is naturally inseparable from the mining process. During the Bitcoin mining process, miners use a lot of calculations to find the right hash value. Once found, they can package the pending transaction into a new block and add it to the Bitcoin blockchain. At the same time, miners will receive a certain amount of Bitcoin as a reward, which is how Bitcoin is issued.
It is worth mentioning that there is an upper limit on the total amount of Bitcoin, and the total amount is expected to be 21 million. As Bitcoin is issued, the difficulty of mining will gradually increase, and the rewards obtained by miners will also decrease. This design is intended to ensure Bitcoin’s value is stable.
Do you
3. My master’s degree is in blockchain, what should I do if I get a job?
Learning a direction will naturally be related to employment issues. Generally speaking, the research directions of a master's degree in computing include the following popular directions, deep learning, big data, cloud computing, distribution, blockchain, and of course, web3 research directions. As for Regarding employment, let’s first look at the fields in which blockchain technology is applied. Where there are applications of technology, there will naturally be technical needs.
Finance and payment: Blockchain technology is widely used in the financial industry, such as cross-border payments, digital currency, supply chain finance, insurance, bond issuance, etc.
Supply chain management: transparency and traceability of the supply chain are achieved through blockchain and tamper resistance, thereby increasing the efficiency and reducing risk of supply chain management.
Internet of Things (IoT): Blockchain technology can ensure secure and trusted transmission of data between IoT devices and improve the stability and reliability of the system.
Healthcare: Blockchain can be used in patient health data management, medical insurance claims, drug traceability, etc. to improve data security and privacy protection in the medical industry.
Energy field: Blockchain technology can be used in energy transactions, distributed energy resource management, power equipment tracking, etc. to improve the management efficiency and transparency of the energy industry.
Digital identity authentication: Realize decentralized management of digital identities through blockchain to improve personal privacy protection and data security.
Copyright protection and intellectual property: Use blockchain technology to ensure copyright protection of original works, intellectual property transactions, etc., and improve the level of intellectual property protection.
In fact, you can see that blockchain and "security" are inseparable. Its essence belongs to the direction of network security and is used to achieve decentralized security authentication and storage. Domestic companies specializing in blockchain are indeed not very popular. Most of them are in start-up companies, so if the research direction of the master's degree is blockchain, since finance was mentioned just now, technology development positions in some financial and securities fund institutions are more suitable. In the past two years, some banks have gradually started to Get involved with blockchain. As the current employment situation becomes more and more difficult, studying for a PhD in blockchain is also a good choice.
4. Face challenges with optimism
Although blockchain and Bitcoin have brought many positive impacts, they also face some challenges during their development. For example, energy consumption in the mining process, regulatory issues of digital currencies, etc. However, as technology continues to advance, more and more solutions are emerging. In short, the research and application of blockchain still have a long way to go, and it is a very promising direction.
I wrote this article in the hope that it will help everyone understand the relationship between mining, blockchain and Bitcoin. Each module of the decentralized distributed storage system of blockchain has research value, such as its consensus algorithm for each block, transmission between different blockchains, expansion of blockchain, and blockchain + applications, etc., focusing on learning principles. At the same time, blockchain especially has identity authentication conditions that cannot be modified with digital signatures, making it more efficient and safer than traditional data storage.
