What technologies are needed to learn blockchain

Time : 19/06/2021 Author : m7dxvs Click : + -
        Based on the future development prospects of blockchain technology and the serious shortage of blockchain talents, many people have initiated the idea of self-learning blockchain technology at present. However, as a technology that has only been emerging for a few years, how can we learn efficiently? Mastering a reasonable place is very important. Distinguishing primary from secondary and grasping the foundation is the only way for efficient learning. Here is a summary of some basic knowledge that you must know to learn blockchain. As the basic structural unit of blockchain, blocks are composed of block headers containing metadata and block bodies containing transaction data. The block header contains three groups of metadata (1) used to connect the previous block, index the data from the parent block hash value (2) mining difficulty, nonce (random number used for the counter of workload proof algorithm), timestamp (3) Merkle tree structure that can summarize and quickly summarize all transaction data in the verification block.
 
        Point to point technology, also known as "peer-to-peer Internet technology", relies on the computing power and bandwidth of the participants in the network, rather than concentrating the dependence on a few servers. An important goal of P2P network is to enable all clients to provide resources, including bandwidth storage space and computing power. Therefore, when a node joins and requests for the system increase, the capacity of the whole system also increases. Hash algorithm is a one-way cryptographic mechanism in blockchain to ensure that transaction information is not tampered with. After receiving a piece of plaintext, the hash algorithm converts it into a piece of hash data with short length and fixed digits in an irreversible way. It has two characteristics: (1) the irreversible encryption process means that we cannot deduce the original plaintext through the output hash data; (2) The output plaintext corresponds to the output hash data one by one. The change of any input information will inevitably lead to the change of the final output hash data.
 
        A timestamp is usually a character sequence that uniquely identifies the time of a moment. Each time stamped block is unique. The timestamp in the blockchain exists in the blockchain from the moment the block is generated. It corresponds to the authentication of each transaction record to prove the authenticity of the transaction record. The timestamp is written directly in the blockchain, and the generated blocks in the blockchain cannot be tampered with. Once tampered, the generated hash value will change and become invalid data. These are the basic knowledge of blockchain technology and the threshold that must be crossed to master blockchain technology. When you know the key points of learning and then face blockchain technology, you will no longer be at a loss.
 
        In addition, in order to improve learning efficiency, it is a good choice to often communicate with professionals or participate in training courses. Many friends don't know much about blockchain technology. But now, with the release of the front-end time, the high-level now recognizes that blockchain has to live. So what foundation do you want to learn blockchain? How to effectively learn and master a reasonable way is very critical. Distinguishing between primary and secondary, and grasping the foundation is the only way to effectively learn. Here is a summary of some basic knowledge that you must know to learn blockchain. Hash algorithm is a one-way cryptographic mechanism in blockchain to ensure that transaction information is not tampered with. After receiving a piece of plaintext, the hash algorithm converts it into a piece of hash data with short length and fixed digits in an irreversible way.

The above is the basic content of learning blockchain. I hope this article will be of some help to friends who want to learn blockchain technology.

        2. Bitcoin system is developed with C. Learning bitcoin system is only used to learn the principle of blockchain, and it is difficult to continue to develop on bitcoin system. When learning the principle of bitcoin, you can use any language such as Java, Java, Python and go. To sum up, learning blockchain development suggestions are based on go language and Java. The learning difficulty of go language is slightly lower than that of Java. Java is an object-oriented programming language, which not only absorbs the advantages of C language, but also discards the difficulty of understanding multiple inheritance in the concepts of C and pointer. Therefore, Java language has two powerful and easy-to-use features.
 
        Java is characterized by simplicity, object-oriented, distributed, robust, security, parallelism and portability, multithreading and dynamic. Java can write desktop applications, web applications, distributed systems and embedded system applications. C is the inheritance of C language. It can be the process of C language programming or abstract data types. As a feature of object-based programming, C can also bear the inheritance and polymorphism of object-oriented programming. C is good at object-oriented programming. It can also perform process based programming, so C is the size of the problem. Appears in the bitcoin project. As the distributed accounting platform behind bitcoin, blockchain has operated stably for nearly eight years without centralized monitoring, supporting a large number of transaction records.
 
        With the development of related applications, the field of blockchain is becoming hot. Many friends see the development prospects and space of blockchain, and they have devoted themselves to blockchain., It has the characteristics of decentralization, most nodes and fairness. Under the pow based consensus mechanism of bitcoin, as long as honest nodes can occupy most of the CPU computing power, attackers cannot tamper with data. If. ", And after that, we will continue to develop and improve the block content block header: block number, hash value of the previous block, hash value of this block, mining random number, mining. In the history of blockchain, bitcoin was first born. At that time, there was no technology and term blockchain. Then the industry extracted the technical architecture and system from bitcoin, which is called.
 
        ? Blockchain core key technologies (1) consensus mechanism: (2) cryptography technology: (3) distributed storage: (4) smart contract: The data released by toptal, the global elite freelancer platform, is even more incredible. From January 2017 to January 2018, the job market is right., Through the shallow to deep explanation, help you gradually deepen your understanding of digital currency and blockchain, then you can lay the foundation for rational investment in blockchain assets. [course content] the principle and implementation behind bitcoin. Let any number of nodes participating in the system calculate and record the communication data in the system over a period of time into a block through cryptographic algorithm, and generate the fingerprint of the block for linking (chain) the next block and consensus verification.
 
        2. Essence. It is a chained data structure that combines data blocks in chronological order, and a distributed ledger that cannot be tampered with and forged in a cryptographic way.
