Introduction

In today's era of rapid technological development, digital currencies are gradually entering the public eye. Whether it's mainstream digital currencies like Bitcoin and Ethereum, or various decentralized finance (DeFi) projects, digital currencies are transforming the face of traditional finance. So, what exactly does digital currency mean? What are the technological principles behind it? And what impact does it have on investors and society? This article will explore these questions in detail and provide you with practical productivity enhancement tips to help you better understand and utilize digital currencies.

What is digital currency?

Digital currency is a type of currency that exists electronically and is mainly used for exchange and transactions. Its characteristic is that transaction information is recorded in digital form, rather than with traditional paper money and coins. These currencies generally use cryptographic technology to ensure the security and privacy of transactions, and they typically operate on decentralized networks, reducing reliance on third-party financial institutions.

  • Blockchain technology
  • Blockchain is the core technology of digital currency, ensuring data immutability and transparency. Every transaction is recorded on the blockchain, forming a chain structure, with each block consisting of multiple transaction records and linked to the previous block through cryptographic algorithms. This allows transactions to be conducted directly between users without the need for intermediaries.

  • Encryption technology
  • The data of digital currencies is protected by cryptographic algorithms to ensure the security of transaction information. Common cryptographic algorithms include SHA-256 (used for Bitcoin) and Ethash (used for Ethereum), which can effectively prevent hacking and forgery.

  • Decentralization
  • Decentralization is a major feature of digital currencies. Traditional financial systems rely on banks and other financial intermediaries to conduct transactions, whereas digital currencies eliminate the need for these intermediaries through distributed networks. This enables users to transact in a trustless environment, enhancing economic autonomy and inclusiveness.
