**课程名称：** 区块链入门 (Blockchain for Beginners) **课程概述：** 本课程专为对区块链技术充满兴趣但毫无基础的初学者设计，旨在提供一个全面的区块链入门指南。通过本课程，学习者将能够深入理解区块链的核心概念，包括区块、节点、公有链和私有链，并了解其广泛的应用。课程将重点阐述区块链与互联网的关键区别。 **核心内容对比：互联网 vs. 区块链** * **互联网：信息机器 vs. 区块链：真相机器** * 互联网促进了信息的高效低成本传输。 * 区块链通过其数据结构、加密技术、时间戳等，确保数据一旦被记录就无法篡改、撤销且可追溯，因此被誉为“真相机器”。 * 与互联网不同，区块链实现了数据的不可篡改性，而互联网上的数据库数据是可以被修改和撤销的。 * **信任机制：核心差异** * 互联网依赖中心化信任机制。 * 区块链采用去中心化信任机制，通过算法构建信任并进行背书。 * 随着数字经济和数字生活比例的不断提高，在某些场景下，去中心化信任机制将比中心化信任机制更具效率和成本效益。 **课程目标：** * 掌握区块链的基本原理，包括区块、节点、公有链和私有链。 * 理解区块链在各个领域的应用。 * 清晰认识区块链与互联网在信息传播和信任机制上的根本区别。 **教学大纲：** (无)
A complete guide for total beginners with no prior knowledge but a keen interest to learn about this evolving technology of Blockchain. Learners will be able to have a complete understanding of blockchain beyond cryptocurrency. Anyone can start their understanding of the fundamentals of blockchain, the blocks, nodes, public and private blockchain, and its application. A COMPARISON BETWEEN BLOCKCHAIN AND INTERNETThe Internet is an information machine while the blockchain is a truth machine*) The Internet is a machine of information that allows people to transmit information to each other with lower cost and higher efficiency.*) The blockchain's data structure, along with a combination of cryptography, timestamps and other technologies, ensures that once a piece of data is linked, it is not tampered with or revoked, but is traceable.*) So blockchain is a truth machine compared to the Internet.*) This is a very big difference between the Internet and blockchain.*) In the Internet era, no matter what kind of database, the data can be revoked and changed, which means there's no Internet-based database is immutable.Trust mechanism is the core difference*) The trust mechanism between the Internet and the blockchain is completely different.*) There is no good or bad. The difference between centralized trust mechanism and the decentralized trust mechanism is not being good or bad, high or low.*) But when the proportion of the digital economy and digital life becomes higher and higher, we may no longer rely on the centralized trust mechanism to make a trusted endorsement in some environments and scenarios.*) Instead, using a decentralized trust mechanism is more efficient and lower-cost.*) This is the core difference between the Internet and blockchain.*) Decentralized trust mechanism relies on algorithms to build trust and make trust endorsement.
