1 Introduction
With the rise of artificial intelligence, more and more people are paying attention to its applications in various industries. In this era, blockchain is emerging as a new type of distributed database system.
Blockchain is a set of technology protocols used to create distributed databases. It can store, verify and share data, and reliably record the historical transformation of all data, thereby ensuring the authenticity, non-forgery and validity of the data. All this makes it very convenient for data to flow between different nodes.
But like any other new technology, blockchain technology also faces many technical challenges. One of the most prominent questions is how to implement it? How to deploy blockchain technology into actual production environments?
In order to solve this problem, the blockchain community, enterprises and individuals are constantly exploring various implementation solutions, such as improving the ease of use and adaptability of blockchain technology from the perspective of developers; from the perspective of operation and maintenance, Improve the stability and security of blockchain technology; promote blockchain technology from the user's perspective so that more people can understand and use it.
This article will use a practical approach and combine multiple typical scenarios to share the author’s experience and thoughts on the implementation of blockchain, hoping to help readers speed up the implementation of blockchain and better understand and apply blockchain technology.
This article mainly elaborates on the following four aspects:
① Background introduction: Current status and application scenarios of blockchain technology.
② Explanation of basic concepts and terms: including blockchain consensus algorithm, smart contract, distributed ledger, etc.
③ Explanation of core algorithm principles, specific operating steps and mathematical formulas: including blockchain consensus mechanism, cryptography principles and Paxos/Raft protocol, etc.
④ Specific code examples and explanations: Implement blockchain practice cases in multiple typical scenarios through Python language.
