Last week, I read the next three chapters of Bitcoin and Cryptocurrency Technologies and watched the corresponding video lectures, which are Bitcoin Mining, Bitcoin and Anonymity, Community, Politics, and Regulation.
1. Learned the mathematical principles of key sharing. Understand the threshold signature, lock time, multi-signature, and other technologies used to realize the multiple security mechanisms of Bitcoin.
2. Understand the three risk types of exchanges: runs, Ponzi schemes, and hackers. A simple market behavior model was established from the perspective of economics to understand the impact of Bitcoin supply and demand on the market.
3. Learned the development history of hardware required for Bitcoin mining, from CPU, GPU, FPGA to ASIC. Understand the current pool hopping and energy consumption problems faced by large professional mining centers, and have basic learning about the concept of mining shares and mining pool reward schemes.
4. Understand the importance of anonymity to Bitcoin, learn basic concepts such as anonymity set, pseudonymity, and unlinkability, and de-anonymization technologies such as transaction graph analysis and Mix Net.
