Course Introduction：Bitcoin has an anonymity mechanism based on decentralization, pseudo-anonymity and encryption, which can protect user privacy, improve security, and ensure financial freedom and transaction freedom. However, the anonymity of Bitcoin transactions is also limited by transaction transparency (blockchain recording), KYC/AML regulations, transaction aggregation, vulnerabilities and attacks, and regulatory scrutiny of privacy coins. Law enforcement agencies can investigate Bitcoin transactions and identify individuals through blockchain analysis, data correlation, enforcement actions, and international cooperation. Anonymization technology can further enhance privacy protection, but it may also be used by criminals.

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
