Abstract: This paper studies the economic functions of blockchain. First, by explaining blockchain technologies from an economic perspective, it introduces the Token Paradigm to summarize mainstream blockchain systems, discusses the true meanings of consensus and trustlessness in the blockchain field, and analyzes the functions of smart contracts. Next, it categorizes major blockchain applications according to how they use tokens and discusses relevant economic problems such as tokens’ monetary features, tokens’ impacts on blockchain platforms, blockchain’s governance functions, and the efficiency and security of blockchain systems. Finally, it discusses the concept of Blockchain as a Financial Infrastructure (BaaFI), which is represented by central bank digital currencies (CBDC) and global stable coins.
