数字货币（Digital Currency）是指一种以电子方式存在的货币，不同于传统的纸币或硬币。它可以用于在线交易、投资或储存。以下是一些关于数字货币的英文词典解释及相关概念： 1. **Digital Currency**: A type of currency that is available only in digital form and not in physical form. It is created and stored using digital technology and can be used for online transactions. 2. **Cryptocurrency**: A subset of digital currency that uses cryptography for security. It operates on decentralized networks based on blockchain technology, making it secure and resistant to fraud. Examples include Bitcoin, Ethereum, and Litecoin. 3. **Blockchain**: A distributed ledger technology that records transactions across multiple computers in a way that ensures the security and transparency of the data. It serves as the backbone for most cryptocurrencies. 4. **Fiat Currency**: Traditional government-issued currency that is not backed by a physical commodity. Examples include the US Dollar, Euro, and Yen. Fiat currencies can be held in both physical (cash) and digital forms. 5. **Wallet**: A digital tool that allows users to store, send, and receive digital currency. Wallets can be software-based (online or offline) or hardware devices designed specifically for cryptocurrency storage. 6. **Mining**: The process by which new cryptocurrency coins are created and transactions are verified on the blockchain. This involves solving complex mathematical problems, which requires significant computational power. 7. **ICO (Initial Coin Offering)**: A fundraising method through which new cryptocurrencies are launched. Investors can purchase tokens at a discounted price before the currency is officially launched. 8. **Exchange**: A platform that facilitates the buying, selling, and trading of cryptocurrencies. These can be centralized, where transactions are managed by a third party, or decentralized, which operate without an intermediary. 9. **Token**: A digital asset created on a blockchain that represents a unit of value. Tokens can serve various functions within a specific ecosystem, such as utility tokens or security tokens. 10. **Decentralized Finance (DeFi)**: A financial system that operates on blockchain technology without the need for traditional banking institutions. DeFi applications enable users to lend, borrow, and trade cryptocurrencies in a peer-to-peer manner. 通过了解这些术语，您可以更深入地理解数字货币的概念及其在现代经济中的应用。数字货币（Digital Currency）是指一种以电子方式存在的货币，不同于传统的纸币或硬币。它可以用于在线交易、投资或储存。以下是一些关于数字货币的英文词典解释及相关概念： 1. **Digital Currency**: A type of currency that is available only in digital form and not in physical form.
