Course Introduction：Blockchain technology is a distributed ledger system used to securely and transparently record transactions. It consists of a chain of linked blockchains containing transaction information, previous block hash, and timestamp. Characteristics of blockchain include decentralization (maintained by a computer network), immutability (transactions cannot be changed once added to the blockchain), and transparency (all transactions are publicly traceable). It has wide applications in many fields such as cryptocurrency, supply chain management, and voting systems.

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.
